enot [183]

Answer:

$y=4x+b$ (four being the slope)

Step-by-step explanation:

So lets use

ΔY/ΔX

or the y2-y1 over x2-x1

$\frac{-8+4}{-3+2}$

$\frac{-4}{-1}$

Therefore, the slope is 4

What is the solution to: <br> T/t-4=t+4/6

S_A_V [24]

$\frac{t}{t-4}= \frac{t+4}{6} \\ t \neq 4 \\ 6t= (t+4)(t-4) \\ 6t=t^2-16 \\ t^2-6t-16=0 \\ D=b^2-4ac=(-6)^2-4*1*(-16)=36+64=100 \\ t_{1,2}= \frac{-bб \sqrt{D} }{2a} \\ t_1= \frac{6-10}{2}=-2 \\ \ t_2= \frac{6+10}{2}=8$

Answer: t=-2, t=8

The original photo was 11 inches wide by 14 inches high the new photo will be 132 inches wide what will be the new height

Aleksandr-060686 [28]

They are similar rectangles. Therefore, the side lengths are proportional:

$\dfrac{11}{132}=\dfrac{14}{x}\ \ \ \ |\text{cross multiply}\\\\11x=132\cdot14\ \ \ \ |:11\\\\x=\dfrac{132\cdot14}{11}\\\\x=\dfrac{12\cdot14}{1}\\\\x=168$

Answer: The new height will be equal 168 inches.
