Answer:
Distributive law of multiplication
Step-by-step explanation:
The acute angles of a right triangle are complementary, so
α + β = 90
(5x/3 +20) + (2x/3) + 14) = 90 . . . . . . substitute given values
7x/3 +34 = 90 . . . . . . . . . . . . . . . . . . . collect terms
7x/3 = 56 . . . . . . . . . . . . . . . . . . . . . . . subtract 34
x = (3/7)*56 = 24 . . . . . . . . . . . . . . . . . multiply by 3/7
Then the value of α is ...
α = 5*24/3 +20 = 60
Answer:
(5,-1)
Step-by-step explanation:
when reflecting over the x-axis:
(x,y) → (x,−y)
get coordinates of D: (5,1)
get coordinates of D': (5,-1)
hope this helped!
Answer:
y = 28x
Step-by-step explanation:
To find the answer, we need to divide the number of bushels by the number of acres. If the quotient is the same for all three divisions, then the quotient is how many times x is multiplied to get y.
140 / 5 = 28
224 / 8 = 28
420 / 15 = 28
Therefore, y = 28x is our answer.
