4x^2 = 9
x^2= 9/4
x= (9/4)^1/2
= + 3/2, - 3/2
Answer:
Step-by-step explanation:
PEMDAS
anything done in the parentheses comes first
so you have to add first then multiply
this is not the distributive property unless the two numbers in parentheses are not like terms
27pi
3/4 * r^2*pi = 36 * 3/4 * pi = 27 pi
Answer:
y = 7/2x+5
Step-by-step explanation:
To find the slope we need two points
(-2,-2) and (0,5)
We can find the slope from the formula
m = (y2-y1)/(x2-x1)
m = (5--2)/(0--2)
m = (5+2)/(0+2)
m = 7/2
The slope is 7/2
The y intercept, or where it crosses the y axis, is 5
Using the slope intercept formula for a line
y= mx+b
y = 7/2x+5
