Write the equation of a line that passes a given point and has the given slope. Answer in standard form. 1. Point (-3,5), m = -7 2. Point (4,7), m = 0
Answer:
y -5 = -7(x +3)y = 7Step-by-step explanation:
The point-slope form of the equation can be used for this. It is generally written as ...
y -k = m(x -h) . . . . . line with slope m through point (h, k)
__
1. For m=-7, (h, k) = (-3, 5), the equation is ...
y -5 = -7(x +3)
__
2. For m=0, (h, k) = (4, 7), the equation is ...
y -7 = 0(x -4)
y = 7
_____
Comment on the form of the answer
Since a point and slope are given, "the equation" is appropriately written in point-slope form. For the second problem the simplified version would be ...
y -7 = 0
Sometimes, "the equation" means the answer is expected in slope-intercept form. In that case, a little rearranging is necessary for the first answer. It becomes ...
y = -7x -16
There are perhaps a dozen different forms that a linear equation can be written in. Considering those, "the equation" is somewhat ambiguous. Your curriculum materials may offer a clue as to the form intended.

The graph shows the relationship between the height of a tree and its age in years. What is the unit rate of growth for the tree? 0.25 feet per year 0.5 feet per year 2 feet per year 3 feet per year
Answer:
The unit rate is 2 feet per year
Step-by-step explanation:
The graph is missing (See attachment)
To determine the unit growth;
First, we have to pick any two corresponding on the x and y axis
When x = 5; y = 10
When x = 1; y = 2
These can be represented as;
[tex](x_1,y_1) = (5,10)[/tex]
[tex](x_2,y_2) = (1,2)[/tex]
Next, is to determine the slope using;
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
Substitute values for x and y
[tex]m = \frac{2 - 10}{1 - 5}[/tex]
[tex]m = \frac{-8}{-4}[/tex]
[tex]m = 2[/tex]
Hence, the unit rate is 2 feet per year
Answer:
the unit rate is 2ft per year i got 100% on a quiz for this
Solve n/3 = 16
Please help :)
Step-by-step explanation:
To solve for n, we need to isolate the variable n.
Multiply both sides of the equation by 3 to cancel out the 3 on the left side, and multiply 3 by 16 to get our final answer.
[tex]\frac{n}{3}*3=n\\16*3=48[/tex]
Our final answer: n = 48
Functions stuff. Picture attached. 30 points. thanks <3
Answer:
A
Step-by-step explanation:
So we have the function:
[tex]f(x)=\frac{3+x}{x-3}[/tex]
And we want to find:
[tex]f(a+2)[/tex]
To do so, substitute in (a+2) for x:
[tex]f(a+2)=\frac{3+(a+2)}{(a+2)-3}[/tex]
Simplify the numerator and denominator. Add 2 and 3 in the numerator. Subtract in the denominator:
[tex]f(a+2)=\frac{5+a}{a-1}[/tex]
The answer is A.
Answer:
[tex]\Large \boxed{\mathrm{A}}[/tex]
Step-by-step explanation:
[tex]\displaystyle f(x) = \frac{3+x}{x-3}[/tex]
For f(a + 2), the input for the function f(x) is (a + 2).
Replacing x with (a + 2).
[tex]\displaystyle f(a+2) = \frac{3+(a+2)}{(a+2)-3}[/tex]
Simplify the rational function.
[tex]\displaystyle f(a+2) = \frac{(3+2)+a}{a+(2-3)}[/tex]
[tex]\displaystyle f(a+2) = \frac{5+a}{a-1}[/tex]
If g(x)= x^2-2x-6 and h(x)= 2x^2-5x+2 find (h-g) (-2)
Answer:
[tex](h - g)( - 2) = 18[/tex]Step-by-step explanation:
g(x) = x² - 2x - 6
h(x) = 2x² - 5x + 2
To find (h-g) (-2) we must first find h - g(x)
To find h - g(x) subtract g(x) from h(x)
We have
[tex](h - g)(x) = {2x}^{2} - 5x + 2 - ( {x}^{2} - 2x - 6) \\ = {2x}^{2} - 5x + 2 - {x}^{2} + 2x + 6 \\ = {2x}^{2} - {x}^{2} - 5x + 2x + 2 + 6[/tex][tex](h - g)(x) = {x}^{2} - 3x + 8[/tex]To find (h-g) (-2) substitute the value of x that's - 2 into (h - g)(x) that's replace every x in (h - g)(x) by - 2
That's
[tex](h - g)( - 2) = ({ - 2})^{2} - 3( - 2) + 8 \\ = 4 + 6 + 8 \\ = 10 + 8[/tex]We have the final answer as
[tex](h - g)( - 2) = 18[/tex]Hope this helps you

tan(theta)=40/58 How do u solve? How do u isolate theta? show work plz!
Answer:
34.60°
Step-by-step explanation:
[tex] \tan \theta = \frac {40}{58}[/tex]
[tex] \tan \theta = 0.689655172[/tex]
[tex] \theta =\tan^{-1} 0.689655172[/tex]
[tex] \theta =34.592288671\degree [/tex]
[tex] \theta =34.60\degree [/tex]
Answer:
[tex]\Large \boxed{\theta = 34.59228868\°}[/tex]
Step-by-step explanation:
tan(θ) = 40/58
To isolate theta (unknown angle), we must take the inverse tangent of both the sides.
tan^-1(tan(θ)) = tan^-1(40/58)
The inverse tangent and tangent cancels.
Simplify the equation.
θ = tan^-1(20/29)
θ = 34.59228868°

The perimeter of a scalene triangle is 14.5 cm. The longest side is twice that of the shortest side. Which equation can be used to find the side lengths if the longest side measures 6.2 cm? A scalene triangle where all sides are of different lengths. The base of the triangle is labeled 2a, is twice that of the shortest side labeled a. The other side is labeled b.
Answer:
9.3 + b = 14.5
Step-by-step explanation:
We are learning about perimeter.
Look for the formula of the perimeter,
P = a + b + c
The question states "The longest side is twice that of the shortest side."
A is the longest side while b is the shortest side.
The shortest side equation would be found below :
6.2 = 2c
c = 3.1
Making a completion of the longest side :
14.5 = 6.2 + 3.1 + b
14.5 + 9.3 + b

Answer:
x = 10 x = -2
Step-by-step explanation:
(x-4)^2 -28 = 8
This is a parabola on the left and a constant line on the right. The parabola will cross the line twice, so there will be two solutions
see attached
Add 28 to each side
(x-4)^2 -28+28 = 8+28
(x-4)^2 = 36
Take the square root of each side
sqrt((x-4)^2) = ±sqrt(36)
x-4 = = ±6
Add 4 to each side
x-4+4 = 4±6
x = 4+6 x = 4-6
x = 10 x = -2
Answer:
x = 10, and x = - 2
Step-by-step explanation:
This equation has two solutions, as it resembles a quadratic equation. When graphed it will be a parabola, and hence intersects the x - intercept at two points, giving us two solutions.
Let's start by expanding the equation,
(x - 4)² - 28 = 8,
(x - 4)² = 28 + 8,
(x - 4)² = 36,
x - 4 = √36, and x - 4 = - √36
x - 4 = 6, and x - 4 = - 6
Solution(s) : x = 10, and x = - 2
Divide 25)1,658.
To find the quotient, start by dividing
into
The required quotient would be 66 8/25 or 66.32 which is determined by dividing 1,658 by any divisor 25.
What is the Quotient?A quotient is defined as the outcome of dividing an integer by any divisor that can be said to be a quotient. The dividend contains the divisor a specific number of times.
What are Arithmetic operations?Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operation is called the arithmetic operator.
* Multiplication operation: Multiplies values on either side of the operator
For example 12×2 = 24
/ Division operation: Divides left-hand operand by right-hand operand
For example 4/2 = 2
We have to determine the quotient.
⇒ 1,658 ÷ 25
Apply the Division operation, and we get
⇒ 1,658 / 25
⇒ 66.32
⇒ 66 8/25
Therefore, the required quotient would be 66 8/25 or 66.32.

Louise is making bags of party favors. She has 16 stickers and 24 bracelets. She wants each bag to be alike, and she needs to use all of the stickers and bracelets. What is the greatest number of party bags she can make?
Find the multiples of each number:
16: 2, 4, 8, 16
24: 2, 3, 4, 6, 8, 12
Now for the greatest number of bags, use the greatest common factor.
The greatest common factor is 8
16 / 8 = 2
24 / 8 = 3
She can make 8 bags which contains 2 stickers and 3 bracelets in each bag.
Answer:
8 party bags.
Step-by-step explanation:
We are dealing with greatest common factor.
16= 1,2,4,8
24=1,2,3,4,6,8,12
Now we see the greatest common factor is 8 bags. Since we know its 8 bags, we can make this conclusion. 16/8= 2 stickers each bag. 24/8=3 bracelets each bag. So, the greatest number of party bags she can make is: 8 bags.
More info: 2 stickers each. 3 bracelets each.

Which is an equivalent equation solved for t? t = t equals StartFraction f minus v Over a EndFraction z. t = t equals StartFraction f minus a Over v EndFraction z. t = a(f – v) t = v(f – a)
Answer:
[tex]t=\dfrac{f-v}{a}[/tex]
Step-by-step explanation:
The equation that represents the final velocity of an object is given by :
f=v+at ....(1)
v is initial velocity
a is acceleration rate
t is time
We need to solve the above equation for t.
Subtracting both sides of equation (1) by v
f-v=v-v+at
f-v=at
Dividing both sides of the above equation by a
[tex]\dfrac{f-v}{a}=\dfrac{at}{a}\\\\t=\dfrac{f-v}{a}[/tex]
So, the value of t is [tex]\dfrac{f-v}{a}[/tex].

♡ Hope this helps! ♡
❀ 0ranges ❀
Answer:
45(1 + 2)
Step-by-step explanation:
To find the greatest common factor, we find the multiples of 45 and 90.
45: 1, 3, 5, 9, 15, 45
90: 1, 2, 3, 5, 6, 9, 15, 18, 45...
The easier way to do this is divide 90 by 2 to get our GCF, 45.
We place the 45 (GCF) in the first box and we place 1 and 2 in the parentheses because when you distribute, we get our original answer.

If she travels at only 20 miles per hour, and half of one hour is 30 minutes, then you would divide the amount of miles (20) by 2 to get 10. I'm sorry this isn't the best explanation, but I hope you understand what I am trying to say :((
A picture has an area of 35cm and is 7cm long.An enlargement of the picture is made is 21cm long.Find the area of the enlargement
Answer: The area of the enlargement is 315cm.
Step-by-step explanation:
If the picture has 35cm as the area and it has a length of 7cm then we can find the width by dividing the area by the length.
w= 35/7
w = 5
So in this care the width of the picture in 5cm.
Now is saying that the picture's length has been enlarge or been dilated to 21 cm. To get from 7cm to 21cm you will have to multiply by 3.
In this situation, we will have to multiply the original picture's width by 3 to find it enlargement.
w= 5*3 = 15
The width is 15cm and the length is 21cm so multiply them to find the area.
A = 15 * 21
A = 315cm
