Answer:
-3/2 and 3/2
Step-by-step explanation:
y=4x^2-9
y=0
4x^2-9=0
4x^2=9
x^2=9/4
x1=-√9/4=-3/2
x2=√9/4=3/2
Answer:
22 minutes
Step-by-step explanation:
First you take away the original amount away from the remaining amount.
$25 - $22.36 = $2.64
Then you take that number and divide it by the cents per minute.
$2.64 ÷ 12 = 0.22
Then that's your answer!
Her call lasted 22 minutes.
Answer:
Due to the distributive property the expression are the same.
Step-by-step explanation:
Sadie expression is "perimeter = 2*(length + width)", while Eric's is "perimeter = 2*length + 2*width". The value for both is always the same for any rectangle, because the expressions are the same due to the distributive property. To prove this we will expand Sadie's expression as shown below:
perimeter = 2*(length + width)
perimeter = 2*length + 2*width
Which is the same as Eric's.
A) f(-2)= - 1/2
f(-1)= -1
f(5)= 1/5
f(7)= 1/7
b) f(-3)= 3-1=2
f(-2)=f(2)= 1
f(0)= -1
f(1)= f(-1)= 0
c) {0}
d) R+
