To find the midpoint:
x=3-1/2= 1
y=5+7/2= 6
Answer:
f(x) = 4x² - 1
Step-by-step explanation:
The given function is; f(x) = x²
Now, when stretched vertically by a factor of 4, we have;
f(x) = 4x²
It's now shifted 1 unit down.. Thus, the final function will be;
f(x) = 4x² - 1
Answer:
3
Step-by-step explanation:
48/16=3
Answer:
$2.50
Step-by-step explanation:
This problem is asking for the unit rate. To solve this problem, you would do $12.50 divided by 5 to get $2.50.
$12.50 divided by 5 = $2.50
Rewrite the equation:
-2x^2 - 3x + 8 = 0
2x^2 + 3x -8 =0
Where a=2, b=3 and c=-8
Then b^2 - 4ac = 3^2 - 4(2)(-8) = 9 + 64 = 73
A positive discriminant implies that the equation has two different real solutions.
Answer: the discriminant is 73, so the equation has 2 real solution
