Consider the following system of equations:

Mashutka [201]

Answer:

Line $y=-2x+3$ intersects line $y=x-5$

Step-by-step explanation:

We are given that

$y=-2x+3$

$y=x-5$

Subtract one equation from other then we get

$-3x+8=0$

$3x=8$

$x=\frac{8}{3}$

Substitute the value of x in first equation then we get

$y=-2(\frac{8}{3})+3=-\frac{16}{3}+3=-\frac{-7}{3}$

Hence, the solution $(\frac{8}{3},-\frac{7}{3})$ is the intersection point of two line equations .

Answer:Line $y=-2x+3$ intersects line $y=x-5$

DerKrebs [107]

Answer:

C. 125 + 120x = 180 + 110x

t = $5.5

Step-by-step explanation:

A.125t + 120 = 180t + 110

B. 120t + 110t = 125 + 180

C. 125 + 120t = 180 + 110t

D. 125 - 120t = 180 - 110t

Friday

$125 + 120t

Saturday

110t + 180

equate Friday and Saturday

125 + 120t = 110t + 180

Collect like terms

125 - 180 = 110t - 120t

-55 = -10t

Divide both sides by -10

t = -55 / -10

= 5.5

t = $5.5
