Answer:
y = 4
Step-by-step explanation:
Since this is an equilateral triangle, all the sides are equal.
7y + 5 = 9y - 3
5 + 3 = 9y - 7y
2y = 8
y = 8 ÷ 2
y = 4
Answer:
11
Step-by-step explanation:
dude just use a calculator lol
Red = r
Blue = b
Green = g
Step 1: Write as algebraic equations.
r = b + 6
g = b - 4
Step 2: Merge the two equations together to form one, by adding them together.
r + g = b + b + 6 - 4
Step 3: Simplify.
r + g = 2b + 2
Step 4: Make b the subject.
2b + 2 = r + g
2b = r + g - 2
b = 0.5(r + g - 2)
ANSWER
b = 0.5(r + g - 2)
Answer:
E’ is (11,-1)
Step-by-step explanation:
Here, we want to get the new coordinates of E
The translation is 4 units right ( add 4 to x-value) and 3 units down ( subtract 3 from y-value)
So for E, we have
(7 + 4, 2-3)
= (11, -1)
