Answer:
y = x - 3
Step-by-step explanation:
Do rise/run to find the slope
8/8 = 1
y = x + b
Plug in a point to find the y-intercept
-5 = -2 + b
-3 = b
The equation will be y = x - 3
The first thing we have is the following equation:
54 ÷ 9 = 6
Let's multiply both sides by 9 to not alter the equality:
(54 ÷ 9) * 9 = 6 * 9
Rewriting we have:
54 = 6 * 9
Answer:
An inverse operation that would be used to verify the equation is:
D. 9 × 6 = 54
The normal price of each cookie is $1.15 derived from the equation, c =today price of each cookie + 0.75
<u>Solution:</u>
Given, Today each cookie costs 0.75 less than the normal price.
Right now if you buy 7 of them it will only cost you 2.80
We have to write an equation to determine the normal price of each cookie(c)
And, we are given that, today 7 cookies cost 2.80
Let the cost of one cookie today be “n”
Then we get,
Today 7 cookies ⇒ 2.8
Then, 1 cookie ⇒ n
By criss cross multiplication we get,

Which means that, each cookie costs $0.4 today
Now, we know that,
<em>normal price of each cookie, c = today price of each cookie + $ 0.75 </em>
c = 0.4 + 0.75
c= 1.15
Hence, the normal cost of each cookie is $1.15 derived from the equation, c = today price of each cookie + 0.75
