Answer:
[tex]\huge\boxed{b=-8}[/tex]
Step-by-step explanation:
[tex]4b+8=3b\\\\4b+8-8=3b-8\\\\4b=3b-8\\\\4b-3b=3b-3b-8\\\\\boxed{b=-8}[/tex]
Answer:
b = -8
Step-by-step explanation:
4b+8=3b
Subtract 4b from each side
4b-4b+8=3b-4b
8 = -b
Multiply each side by -1
-8 = b
What is X I need help i dont know how to do this
Answer:
x = 75
Step-by-step explanation:
Triangle BDH
The angle must add to 180 degrees
36+ 39 + DHB = 180
75 + DHB = 180
DBH = 180-75
DHB = 105
DBH + x = 180 since it is a straight line
105+ x = 180
x = 75
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
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
Evaluate the function.
[tex]f(x) = - x^{2} - 7x - 5[/tex]
Find
[tex]f( - 5)[/tex]
===================================================
Explanation:
Everywhere you see an x, replace it with -5. Then use the order of operations PEMDAS to simplify
[tex]f(x) = -x^2 - 7x - 5\\\\f(-5) = -(-5)^2 - 7(-5) - 5\\\\f(-5) = -(25) - 7(-5) - 5\\\\f(-5) = -25 + 35 - 5\\\\f(-5) = 10 - 5\\\\f(-5) = 5\\\\[/tex]
Keep in mind that for the x^2 term, you are squaring all of x = -5, which includes the negative as well. So that means
x^2 = (-5)^2 = (-5)*(-5) = 25
but sticking a negative out front makes
-x^2 = -(-5)^2 = -25
If you're good at math i'd love some help :)
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

The members of one possible set C ={4,5,8,10}
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]
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°

What is the volume of the following prism?
A. 96 in³
B. 480 in³
C. 48 in³
D. 108 in³
Answer:
C
Step-by-step explanation:
To find the volume, we can multiply the area of the base by the height. The base is a triangle so its area is (4 * 3) / 2 = 6 and the height is 8 so the volume is 6 * 8 = 48 in³.
Answer:
C. Vol = 48 in³
Step-by-step explanation:
Vol = base area of a triangle x height.
Vol = ( 1/2 * 3 * 4 ) x 8
Vol = 48 in³

Answer:
90
Step-by-step explanation:
Be sure to use PEMDAS. Begin with parentheses, the move to multiplication, then adding.
20 + 3(7 + 4) + 5 + 2(7+9)
20 + 3(11) + 5 + 2(16)
20 + 33 + 5 + 32
You can add those final four numbers in any order you want, to get a sum of 90.
Answer:
Your answer will be 90
Step-by-step explanation
First you will have to answer what's inside the parentheses
7 + 4 = 11 , 7 + 9 = 16
Then you multiply what is next to the parentheses
3×11 = 33, 2×16 = 32
Finally you will have to add
20 + 33 =53
53 + 5 =58
58 + 32 = 90
The point is doing PEMDAS

You need to find the GCF (greatest common factor) of 45 and 90, which is 45.
45 times ? gets you 45
? would be 1
45 times 1 equals 45.
45 times ? gets you 90
? would be 2
45 times 2 equals 90
45(1+2) = 45+90 = 135
♡ 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.
45(1 + 2)

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.
Anna was driving east on a freeway at a constant velocity. She was 570 kilometers west of
her exit. In 2 hours, she drove one-third of the way to her exit. What was her velocity?
Answer:
Her velocity is 95 km/hour
Step-by-step explanation:
The given information includes;
The direction to which Anna was driving = Eastward
Her initial location on the journey = 570 kilometres west of her her exit
The distance she drove in 2 hours = 1/3 of the way to her exit
Therefore, the distance she drove in 2 hours = 1/3×570 = 190 m
Her velocity = Her distance covered/(The time it take to cover the distance)
Which gives;
Her velocity = (190 km)/(2 hours) = 95 km/hour
Her velocity = 95 km/hour.

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
