Y - y₁ = m(x - x₁)
y - 5 = ⁵/₆[x - (-6)]
y - 5 = ⁵/₆(x + 6)
y - 5 = ⁵/₆(x) + ⁵/₆(6)
y - 5 = ⁵/₆x + 5
+ 5 + 5
y = ⁵/₆x + 10
y - y₁ = m(x - x₁)
y - 5 = -1¹/₅[x - (-6)]
y - 5 = 1¹/₅(x + 6)
y - 5 = 1¹/₅(x) + 1¹/₅(6)
y - 5 = 1¹/₅x + 7¹/₅
+ 5 + 5
y = 1¹/₅x + 12¹/₅
Take .26 • 52 = 13.52
So 26% of 52 = 13.52

Answer:
5t - 18
Step-by-step explanation:
(7 - 3t) - 5(-1.6t + 5)
First, we need to distribute the right side to get rid of the parentheses.
-5 * -1.6t = 8t
-5 * 5 = -25
8t - 25
Now, we have
(7 - 3t) + 8t - 25
We no longer need the parentheses on the left side.
7 - 3t + 8t - 25
Combine like terms.
-3t and 8t are like terms.
-3t + 8t = 8t - 3t
8t - 3t = 5t
7 and -25 are like terms.
7 - 25 = -18
5t - 18
Because 5t and -18 are NOT like terms, this is as far as we can simplify. So, we have our answer.
Please let me know if you have any further questions. I'm always happy to help!

Answer:
I believe that her theory is correct
Step-by-step explanation:
this is because the ratio of cups of sugar to cups of flour is 1:3 and if we times both sides by 3 we get 3:9 which is the answer she presents
