As Sally and George practice for the SAT their scores on practice test rise Sally’s current score is 850 and it is rising by 10

aleksley [76]

Answer:

a) 7 weeks b) George's

Step-by-step explanation:

Sally's score can be modeled by 10x+850.

George's score can be modeled by 50x+570.

We can set them equal to each other to see when they intersect.

10x+850=50x+570

40x=280

x=7

If George overtakes her in the 7th week, of course he'll have the higher score in 12 weeks.

Determine the slope of the line that passes through the points (-4, 6) and (0,4).

gavmur [86]

Answer:

B.) $m=-\frac{1}{2}$

Step-by-step explanation:

use the slope rule

$\frac{rise}{run} \\\\\\frac{y2-y1}{x2-x1}$

Fill in values

$\frac{4-6}{0-(-4)}$

Simplify

$\frac{-2}{4}\\-\frac{2}{4}$

Simplify further

$m=-\frac{1}{2}$

Done.

Solve for x. x + 14 5x - 74 x = [?]

otez555 [7]

Answer:

$\huge \fbox \pink {A}\huge \fbox \green {n}\huge \fbox \blue {s}\huge \fbox \red {w}\huge \fbox \purple {e}\huge \fbox \orange {r}$

x + 14 = 5x - 74 (corresponding angles are equal to each other)

$x + 14 = 5x - 74 \\ 14 + 74 = 5x - x \\ 88 = 4x \\ \frac{88}{4} = x \\ 22 = x$
