Answer:
see explanation
Step-by-step explanation:
The opposite sides of a parallelogram are congruent, then
19x - 9 = 13x + 15 ( subtract 13x from both sides )
6x - 9 = 15 ( add 9 to both sides )
6x = 24 ( divide both sides by 6 )
x = 4
---------------------------------------------
Consecutive angles are supplementary, sum to 180° , that is
10y - 37 + 4y + 7 = 180
14y - 30 = 180 ( add 30 to both sides )
14y = 210 ( divide both sides by 14 )
y = 15
Then
∠ R = 10y - 37 = 10(15) - 37 = 150 - 37 = 113°
Then
∠ P = 113° ( opposite angles are congruent )
The answer to number 5 is 600 feet ,300 secondsThe answer to number 8 is 30 seconds will be 40ft,and 45 seconds will be 60 ft,90 seconds will be 120 ft.
Answer:
-1/3x+3 = x-1
Step-by-step explanation:
The solution is (3,-2)
Check and see if the point solves the equation
-1/3x+3 = x-1
-1/3(3) +3 = 3-1
-1+3 = 3-1
2=2 yes
Answer:
C
Step-by-step explanation:
so taking the slope from the points (0,1) and (2,2)
we get slope= 2-1/2-0=1/2 the y intercept is one
so y=mx+b(where m is the slope and b is the y intercept)
we get= y=1/2x+1
which is C
