4x - 3 = 9
4x = 9 + 3
4x = 12
x = 3
hope that helps, God bless!
<u>End behavior: </u>
The parent function is: f(x) = x³, which starts (from the left side) at -∞ and ends (on the right side) at +∞.
<u>Zeroes:</u>
f(x) = x³ + 2x² - 8x
0 = x³ + 2x² - 8x
0 = x(x² + 2x - 8)
0 = x(x + 4)(x - 2)
0 = x 0 = x + 4 0 = x - 2
x = 0 x = -4 x = 2
<u>Intervals:</u>
Put the zeroes in order: -4, 0, 2
since f(x) is increasing from the left then the interval from -4 to 0 is positive and the interval from 0 to 2 is negative.

Answer: X=6 or X= -6
Step-by-step explanation:
To find what x equals, square root both sides. The square root of 36 is positive or negative 6
Option 4 is twice as big as option 2 those two are the ones similar to each other
Answer:
a:30 b:70 c:80
Step-by-step explanation:
triangle= 180*
3:7:8= 180*
7+3+8= 18
180/18= 10
a= 3x10= 30*
b=7x10= 70*
c=8x10= 80*
