Simplified expression for the amount is 10(9m + 50)
Step-by-step explanation:
- Step 1: Form an equation for the amount of money Troy has received after m months.
If the total months that Troy's grandfather has given him money is m, then the number of months that Troy's mother has given him money is m - 4.
⇒ Total amount in account = 700 + 40m + 50(m - 4)
= 700 + 40m + 50m - 200
= 90m + 500 = 10(9m + 50)
If we expand bx to jx and kx we have:
5y^2-2y-7
5y^2-7y+5y-7 then factor...
y(5y-7)+1(5y-7)
(y+1)(5y-7)
So the other factor is:
(y+1)
Answer:
$12
Explanation: 60 x .2= 12 + 60= $72
Answer:
See below ~
Step-by-step explanation:
(a) To find y-intercept :
- y = -x² + 2x + 15
- y = -(0)² + 2(0) + 15
- y = 15
- M is : (0, 15)
(b) Finding x-intercepts :
- 0 = -x² + 2x + 15
- -x² + 5x - 3x + 15 = 0
- x(-x + 5) + 3(-x + 5) = 0
- (x + 3)(-x + 5) = 0
- x + 3 = 0 ⇒ x = -3
- -x + 5 = 0 ⇒ x = 5
- P and Q are : (-3, 0) and (5, 0)
(C) Finding vertex :
- Vertex is (h, k)
- h = -b/2a = -2/2(-1) = 1
- k = -(1)² + 2(1) + 15
- k = -1 + 2 + 15
- k = 16
- The maximum point is : (1, 16)
Answer:
2x
Step-by-step explanation:
6x^2
-------
3x
6/3 =2
x^2/x =x*x/x =x
6x^2
------- = 2x
