Answer:
4
Step-by-step explanation:
7x = x² - 8
=> x² - 7x - 8 = 0
use quadratic formula:
a = 1, b = -7, c = -8
x = <em>(pls ignore the "A" I don't know why it's showing up)</em>
=> x =
=> x = = 4 or = -5 <em>(the answer is only 4 since it's asking for the positive solution)</em>
y<2/3x-1
plotted point is on -1
slope of the line is rise 2, run 3
so its the last option
a) 16, 19, 22, 25, 28, 31, 34, 37, 40
b) 1, 3, 9, 27, 81, 243, 729, 2187
a) Add 3 on every number.
b) Multiply every number by 3.
