Answer:
D.
b = 175; which is the initial # of pages to start
Step-by-step explanation:
you can find the slope to find b or y-intercept (x=0) for equation
y=mx+b
to find m = (y2-y1)/(x2-x1)
(x1,y1) = (9, 100)
(x2, y2) = (15, 50)
m = (50-100) / (15-9) = -50/6 = -25/3
let use point (15, 50)
y=mx+b
50 = -25/3*x + b
50 = (-25/3)*(15) + b
50 = -125 + b
b = 175; which is the initial # of pages to start
Answer:
A). 1/2x + 4
Step-by-step explanation:
The slope is positive since the slant is towards the right and the slope is 1/2 since using rise/run shown that it is 1/2.
8,000 meters in 8 kilometers
let's first off apply a log rule of cancellation, keeping in mind that, first off is ln(), not in(), and that ln() is just a shortcut to logₑ.

Answer:
$120
Step-by-step explanation:
35% : 42
100% : X
42/35 = X/100
X = 100×42/35
X = $120
