To make a poster, Jeff will enlarge the length and width of a photograph by a scale factor of 5. The photograph is 8 inches wide and 10 inches long,
What will be the area of the poster?

b

step-by-step explanation:

the word superfluous means unnecessary

2x^2+5x+17

your welcome. : )

my guess would be b and d, but i didn’t actually get out the pen and paper. lol

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4
