What is this
y=3x-4
Answer:
4/3 or 1.3
Step-by-step explanation:
y= 3x-4
To find x- intercept/zero, Substuite y=0.
0= 3 x -4
Move the variable to the left-hand side and change its sign
-3x= -4
Divide both sides of the equation by -3
x= 4/3
(1.3 as a decimal)
1) the sum of 8 and t
3) the product of 5 and b
Step-by-step explanation:
When we say sum we are referring to addition.
And a number and a variable(letter) can't be added. So the sum of 8 and t can't be added.
The sum of 8 and t is;
8+t
When we talk about product or finding the product of a number we are referring to the number we get after multiplying two or more numbers.
And note that with multiplication, a number and a variable(letter) can be multiplied.
The product of 5 and b is;
5×b=5b

Answer:
C. y + 7 = -7(x - 3)Step-by-step explanation:
The equation of a line is:
y - y₀ = m(x - x₀)
where m is the slope and (x₀, y₀) is the point which the line passes through
The product of slopes of two perpendicular lines is -1
so if given lines slope is ¹/₇ them:
¹/₇·m = -1
m = -7
(3, -7) ⇒ x₀ = 3, y₀ = -7
Therefore:
y - (-7) = -7(x - 3)
y + 7 = -7(x - 3)
At o degrees Celsius, the volume of a gas is 22 liters. For each degree the temperature T (in degrees Celsius) increases, the volume V (in liters) of gas increases by two twenty fifths. Write an equation that represents the volume of the gas in terms of the temperature.
Answer:
[tex]V=\dfrac{2}{25}T+22[/tex]
Step-by-step explanation:
It is given that,
At 0 degrees Celsius, the volume of a gas is 22 liters. For each degree the temperature T (in degrees Celsius) increases, the volume V (in liters) of gas increases by 2/25.
If we take a cartesian coordinate, the line passes through (0,22). The slope of the line is 2/25.
The equation of a point-slope form is given by :
[tex]y-y_1=m(x-x_1)\\\\y-22=\dfrac{2}{25}(x-0)\\\\y-22=\dfrac{2x}{25}\\\\y=\dfrac{2x}{25}+22[/tex]
Here, x will be temperature and y will be volume. So,
[tex]V=\dfrac{2}{25}T+22[/tex]
Hence, the equation that represents the volume in terms of the temperature is [tex]V=\dfrac{2}{25}T+22[/tex]

Please answer this there is a link to the photo
Answer:
588
Step-by-step explanation:
In a factor tree, I mostly like to look from down to up so that I can track down the non-square number. In a square number, there must be two factors that are exactly the same as each other, and when multiplied gives that square number.
So based on the 5 × 5, 2 × 2, and 7 × 7, we can tell that 25, 4 and 49 are all square numbers. We move up one level. Since the factors of 196 are square numbers, 196 is also a square number since it consists of 2² × 7².
We move another step up. 588 consists of 3 and 196. We know that 196 is a square number, but 3 is a prime number, which means that 3 only has a factor of 3 and itself. Thus, 588 is not a perfect square number since there should be a double factor for 3.
If A = 117 degrees, B = 12 degrees, and b = 12, find a. Round to the nearest tenth.
Answer:
a = 51.4Step-by-step explanation:
sinA = sinB
a b
sin(117) = sin(12)
a 12
a * sin(12) = 12 * sin(117)
a = 12 * sin(117)
sin(12)
a = 51.4

Write y – 3 = 23 (x – 2) in standard form. PLEASE HELP BEST ANSWER AND EXPLANATION WILL GET BRAINLIEST!!
Answer:
23x -y = 43
Step-by-step explanation:
in slope intercept form, we have y=mx+b where m=slope, b= y intercept
first let's simplify the expression 23(x-2)
y-3 = 23x - 23*2
y-3 = 23x - 46
now add 3 to both sides to move numbers to the right hand side
y -3 +3 = 23x -46 +3
y = 23x - 43
convert to standard form by having x and y on one side, numbers on the other.
add 43 to both sides
y+43 = 23x
subtract y from both sides
43 = 23x - y

Answer:p(x) = x^3 - 5x^2 - 4x + 20
Step-by-step explanation:
1, - 1, 2, - 2, 4, - 4, 5, - 5, 10, - 10, 20, - 20
P(2) = 2^3 - 5 × 2^2 - 4 × 2 + 20
= 8 - 20 - 8 + 20 = 0,
so, 2 is one of its roots (zeros)
So,
x - 2 is one of the factors of p(x)
So, on dividing p(x) by x - 2 we get
P(x) = (x - 2) (x^2 - 3x - 10)
= (x - 2) (x^2 - 5x + 2x - 10)
= (x - 2) {x (x - 5) + 2 (x - 5)}
= (x - 2) {(x - 5) (x + 2)}
P(x) = (x - 5) (x - 2) (x + 2)
For zeros, let p(x) = 0
=> (x - 5) (x - 2) (x + 2) = 0
Either
(x - 5) = 0
Or
(x - 2) = 0
Or
(x + 2) = 0
So, x = 5, 2, - 2
Solve the exponential equation: 6–2x = 62 – 3x
Question 1 options:
A)
4
B)
–2
C)
3
D)
2
Answer:
x = 56
Step-by-step explanation:
Collect like terms:6 - 2x = 62 - 3x
-2x + 3x = 62 - 6
1x = 56
x = 56
Check your answer:6 - 2(56) = 62 - 3(56)
6 - 112 = 62 - 168
-106 = -106

Is 2 a solution of 4x + 12= 4? Complete the statement. The equation is (true, false) when x = 2, so 2 (is, is not) a solution. WILL MARK BRAINLIEST
Answer:
The answer is false and is not
Explanation:
Given the equation - [tex]4x+12=4[/tex]
Substitute x = 2 in the equation
[tex]4(2)+12=4\\8+12=4\\20=4[/tex]
Thus, the equation is false. When the equation is false, meaning that the coordinate x-term isn't passed by the line. (Rather say that the point is not the part of the graph.)
The equation is false is our first answer.
If the equation is false, that means the given value is not part of the graph, thus making the x-value not the solution.
Answer:
The equation is FALSE when x=2, so 2 IS NOT a solution.

Identify the correct phrase to complete the statement.
A central angle has a measure of 1 radian if:
A. the length of the arc it intercepts is twice the length of the radius.
B. the central angle is 90°.
C. the length of the arc it intercepts is the same as the length of the
radius.
O D. the radius has a length of 1
Answer:
C.) the length of the arc it intercepts is the same as the length of the radius
Step-by-step explanation:
The length of the arc it intercepts is the same as the length of the
radius option (C) is correct.
What is a circle?It is defined as the combination of points that, and every point has an equal distance from a fixed point (called the center of a circle).
As we know, the relationship between arc length and the central angle:
s = rθ
[tex]\rm \theta = \dfrac{s}{r}[/tex]
Where 's' is the arc length and θ is the central angle, r is the radius of the circle.
If θ = 1 radian
Then,
s = r
Thus, the length of the arc it intercepts is the same as the length of the
radius option (C) is correct.

Walkway Over the Hudson, a bridge that crosses the Hudson River in Poughkeepsie, is 2.063
kilometers long. Anping Bridge, which was built in China 850 years ago, is 2.07 kilometers long.
a. What is the total span of both bridges?
Show your thinking
b. How much longer is the Anping Bridge
than the Walkway Over the Hudson?
Answer: 4.126 km
Step-by-step explanation:
First, We have to find total span of both bridges
As Question indicates 'total' ,that is, we have to find bridge length in total ( You can join Bridges to have better understanding)
Now, Walkway over hundson Bridge length= 2.063 km
Amping bridge length= 2.07 km
So, Total span of both bridges = 2.063+2.07 = 4.133 km
b) Now Leah wanna walk across and back on walkway over hudson ,that is, she wanna return to starting point from where she walk forth
So,that means, she walk double distance of length of walkway over hudson
So, total distance = 2× 2.063
= 4.126 km
hope this helps,
