Alright let’s start with (2m+2y+5). If m=2 and y=-1, then you can plug in (2(2)+2(-1)+5). 2(2) is 4, so 4+2(-1)+5. 2(-1) is -2, so now 4+-2+5. And addition sign and a negative sigh cancel to make 4-2+5.

Answer: 7

Now (1m+7y-10), again we plug in m=2 and y=-1. (1(2)+7(-1)-10). 1(2) is 2. 7(-1) is -7. So now (2+-7-10), and the addition sign and negative sign make it (2-7-10). 2-7 is -5 minus 10.

Answer: -15

Answer:

  P = -16(x -28)² +1024

Step-by-step explanation:

The equation can be written in vertex form as ...

  P = -a(x -h)² +k

where (h, k) is the vertex, and 'a' is a scale factor. We are given the vertex (h, k) = (28, 1024) and another point (x, P) = (10, -4160). Using these points, we can find the value of 'a'.

  -4160 = -a(10 -28)² +1024

  -5184 = -324a . . . . simplilfy

  a = 5184/324 = 16 . . . . divide by the coefficient of 'a'

A suitable quadratic relation is ...

  P = -16(x -28)² +1024

Ron works at the local bookstore for an hour every day. He earns $5 daily from this job. If he adds this amount to his daily all
eimsori [14]
$5

The equation is true when we plug 5 in for x. So, x=5 and therefore Ron’s daily allowance is $5.

7(5+5) = 70
7(10) = 70
70 = 70 ✔️

7(10+5) = 70
7(15) = 70
105 = 70 ❌

7(15+5) = 70
7(20) = 70
140 = 70 ❌

7(20+5) = 70
7(25) = 70
175 = 70 ❌
