A lot of numbers and it really depends
Answer:
(3, 0 )
Step-by-step explanation:
Given a parabola in standard form
y = ax² + bx + c (a ≠ 0 )
Then the x- coordinate of the vertex is
= - 
y = 5x² - 30x + 45 ← is in standard form
with a = 5, b = - 30 , then
= -
= 3
Substitute x = 3 into the function for corresponding value of y
y = 5(3)² - 30(3) + 45 = 45 - 90 + 45 = 0
vertex = (3, 0 )
Answer:
1,414
Step-by-step explanation:
2,525 * ( 1 - 30% ) * ( 1 - 20%) = 2,525 *0.7*0.8 = 1,767.5 * 0.8 = 1,414
Answer:
m ≤ 4250
Step-by-step explanation:
What we know:
Mr. Loureiro has to pay $25 plus 10 cents every mile.
The equation becomes 25 + 0.1x = 450
25 + 0.1x = 450
0.1x = 450 - 25
0.1x = 425
x = 4250
So, Mr. Loureiro can travel no more than 4250 mi. (m ≤ 4250)
Answer:
2(8x)+5(8)
8
Step-by-step explanation:
The computation of the number that should go to finished the expression is as follows:
Given that
Kali earns $ 8 per hour.
If she worked for n hours so it would be $8n
And she worked on both monday and tuesday for x hours
So, the x hour earning is $8x and for both days it would be $2 (8x)
In addition to this, she worked 5 hours on thursday
So her earnings on thursday is 5×8=40
So, the total earning for the week is
2(8x)+5(8)
