Answer:

y = 9/2x -9

Step-by-step explanation:

it's kind of hard to see but it looks like the line intersects the y axis at -9. then using two points on the line, (2,0) and (0, -9) you can find the slope with the equation

m= y2-y1/x2-x1 or m = -9-0/0-2 = -9/-2 = 9/2

What is -16+4 (2g-18)=0

IgorLugansk [536]

-16 + 4(2g - 18) = 0

Distribute 4 inside the parentheses.

-16 + (8g - 72) = 0

Combine like terms (-16 - 72).

-88 + 8g = 0

Add 88 to both sides.

8g = 88

Divide both sides by 8.

$\boxed {g=11}$

Which of the following statements describe the graphs of the solution set flr this inequality select two that apply

Helga [31]

Answer:

1st . The shaded region of the graph ....

2nd. The graph line is solid.

4th. The ordered pair (2 ; 5) is part of the solution set.

Step-by-step explanation:

. Because y is greater or equal than the line, everything above the line is part of the solution.

. Since y is greater or equal, the line is solid. If y was only greater the line would have been dotted.

. The pair (2 ; 5) represent the x = 2 w/ y = 5, and reading the graph you can see the at this point the lines passes through it.

notsponge [240]

Answer: $=-7x+5$

Step-by-step explanation:

$-2\left(3x-4\right)-x-3$

$=-\left(2\left(3x-4\right)+x+3\right)$

$=-\left(6x-8+x+3\right)$

$=-\left(7x-5\right)$

$=-7x+5$

Calvin paints pictures and sells them at art shows. He charges $ 56.25 for a large painting. He charges $25.80 for a small paint

crimeas [40]

He made $ 394.90 because you need to add all the large paintings then the small ones then add them all

Write a linear function f with f(0)=7 and f(3)=1.

choli [55]

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

a = ( 0 , 7 ) & b = ( 3 , 1 )

First need to find the slope using the following equation :

$slope = \frac{y(b) - y(a)}{x(b) - x(a)} \\$

$slope = \frac{1 - 7}{3 - 0} \\$

$slope = \frac{ - 6}{3} \\$

$slope = - 2$

_________________________________

We have following equation to find the point-slope form of the linear functions using the slope and one of the through points .

$y - y(0) = m \times ( \: x - x(0) \: )$

$x(0) = x - coordinate \: \: of \: \: through \: \: point \\$

$y(0) = y - coordinate \: \: of \: \: through \: \: point \\$

$m = slope$

I choose point (( a )) to put in the equation.

$y - 7 = - 2 \times (x - 0)$

$y - 7 = - 2x + 0$

$y - 7 = - 2x$

Add sides 7

$y - 7 + 7 = - 2x + 7$

$y = - 2x + 7$

This the slope-intercept form .

Done...
