Answer:

Slope intercept form is y = mx + b

m is slope

b is y intercept

y = -4/5x + -9

Answer:

yes.

Step-by-step explanation:

slope intercept form is y=mx+b

b is the y intercept, m is the slope, and x is x.

for

1. it would be

y= -4/5x -9

2. You take the points and do (y2-y1) DIVIDED BY (x2-x1)

it would look like:

(5- -3) / (3-0) = (8/3)

Then plug in one of the sets of numbers for x and y, to get y intercept.

5=8/3(3)+b

b=-3

So.. slope intercept would be y=8/3x -3

9) If m/1 = 45° and 21 and 22 are complementary angles. Find m22.

Allisa [31]

❄ Hi there,

keeping in mind that the sum of complementary angles is 90°,

set up an equation, letting $\angle2$ be x –

$\triangleright \ \sf{\angle1+x=90}$ {and we know that $\boxed{\angle1=45}$ }

$\triangleright \ \sf{45+x=90}$

$\triangleright \ \sf{x=90-45}$

$\triangleright \ \sf{x=45}$

$\triangleright \ \sf{\angle2=45\textdegree}$

__________

Keeping in mind that a right angle is 90°,

set up an equation, letting $\angle1$ be x:

$\triangleright \ \sf{x+\angle2=90}$ {and we know that $\boxed{\angle2=63}$ }

$\triangleright \ \sf{x+63=90}$

$\triangleright \ \sf{x=27}$

$\triangleright \ \sf{\angle1=47\textdegree}$

Given g(x) = −3x + 4

Goshia [24]

Answer:

The average rate of change of g from x = a to x = a + h is -3.

Step-by-step explanation:

We are given the function:

$g(x) = -3x + 4$

And we want to determine its average rate of change of the function for x = a and x = a + h.

To determine the average rate of change, we find the slope of the function between the two points. In other words:

$\displaystyle \text{Avg} = \frac{g(a + h) - g(a) }{(a + h ) - a}$

Simplify:

$\displaystyle \begin{aligned} \text{Avg} &= \frac{g(a + h) - g(a) }{(a + h ) - a} \\ \\ &=\frac{(-3(a+h) + 4) - (-3a+4)}{h} \\ \\ &= \frac{(-3a -3h + 4) + (3a - 4) }{h} \\ \\ &= \frac{-3h}{h} \\ \\ &= -3\end{aligned}$

In conclusion, the average rate of change of g from x = a to x = a + h is -3.

This is the expected result, as function g is linear, so its rate of change would be constant.

If x-9 is a factor of x-5x-36 what is the other factor

dimaraw [331]

The other factor would be (x + 4). We can find this by using synthetic division. To do this, we must first find the divisor, which would be 9, if we let x - 9 equal to zero and solve for x. Then, for the dividend, we can use the coefficients and constant term values.
9| 1 -5 -36
 9 36
1 4 0
Therefore, the other expression (x + 9) would be (x + 4). Hope this helped!

The length of a rectangular garden is 3yd more than twice it’s width. The perimeter of the garden is 36yd. What are the width an

Basile [38]

2L + 2W = 36
2(3+2W) + 2W = 36
6 + 4W + 2W = 36
6W + 6 = 36
-6 = -6
6W=30
W= 30/6 = 5 L= 3 + 2W = 3 +2 (5) = 3 +10= 13

Width is 5
Length is 13

PLSSSSSSS HELPPPPPPP I WILL GIVE BRAINLIESTTTTTTTTTT!!!!!!!!!!!!!!!!!!!!!PLSSSSSSS HELPPPPPPP I WILL GIVE BRAINLIESTTTTTTTTTT!!!

Darya [45]

Answer:

Step-by-step explanation:

so formula for the volume of a cylinder is:

(πr^2)*h

so the diameter is given to us which is

2r=10 cm

then r=5 cm

h=6 cm and r=5 cm so we just plug it in

(5^2)*6π

25*6π

150π cm^3 or approximately 471.239 cm^3
