X is equal to -9 because you add 6 to both sides and get -x=9 but since your trying to get positive x you change it to -9. Hope that isn’t confusing!

What is the solution of y= -5x + 1 and y= 3x - 2

Nezavi [6.7K]

Answer:

x=3/8, y=-7/8. (3/8, -7/8).

Step-by-step explanation:

y=-5x+1

y=3x-2

----------

-5x+1=3x-2

-5x-3x+1=-2

-8x+1=-2

-8x=-2-1

-8x=-3

8x=3

x=3/8

y=3(3/8)-2=9/8-2=9/8-16/8=-7/8

The cost of a pound of nails increased from $2.17 to $2.52. What is the percent of increase to the nearest whole-number perce

Cloud [144]

Answer:

16% is the percent of increase to the nearest whole-number percent.

Step-by-step explanation:

As the cost of a pound of nails increased from $2.17 to $2.52.

$2.52 - $2.17 = $0.35

so dividing the 0.35 by 2.17 would give us the percetange of increase

0.35/2.17 = 0.16 which is 16%.

Therefore, 16% is the percent of increase to the nearest whole-number percent.

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...
