Answer:
x = 6 y = -9 (I took a complicated route so if my explanation doesn't make sense It's fine)
Step-by-step explanation:
DAY = FUN
F = (7x+2y) = 24
If DAY = FUN then D = F making (7x + 2y) = 24
This means A = U so you have to find U with 24+126=150
A triangle is 180 degrees so you would do 180-150=30
U = 30
This also makes (8x+2y) = 30
8x + 2y = 30
-8x -8x
2y = 30 - 8x
Divide everything by 2
y = 15 - 4x
Doing this you can take 7x + 2y = 24 and plug in 7x + 2(15 - 4x) = 24
Multiply it 7x + 30 - 8x = 24
Add like terms -x + 30 = 24
Subtract 30 -x = -6
Divide by -1 x = 6
Now take one of the equations and plug it in 7(6) + 2y = 24
Multiply 42 + 2y = 24
Subtract 2y = -18
Divide by 2 y = -9
Answer:
15 m
Step-by-step explanation:
First split the shape into a square and a triangle, then find the area of the square by multipliyng the sides to get.
Next find the length of the traignel by subtracting 3 from 9 to get for then find the area of the triangle by multiplying 4 by 3 to get 12 then divide by 2 to get the area which is 6.
Finally add the 9 to the 6 to get 15
3 * 3 = 9
9 - 3 = 4
4 * 3 = 12/2 = 6
6+9=15
Answer:
NO WAY ITS INSANE
Step-by-step explanation:
Answer:
y = - 5x² - 10x + 2
Step-by-step explanation:
y = - 5(x + 1)² + 7 ← expand (x + 1)² using FOIL
= - 5(x² + 2x + 1) + 7 ← distribute parenthesis by - 5
= - 5x² - 10x - 5 + 7 ← collect like terms
= -5x² - 10x + 2 ← in standard form
Answer:
6
Step-by-step explanation:
Arc length = radius * central angle
s = rθ
A circle is 2π radians, so 1/3 of that is 2/3 π.
Given that s = 12 and θ = 2/3 π:
12 = r (2/3 π)
r = 18/π
r ≈ 6
