Answer:
its the last answer, the $735
Step-by-step explanation:
2r + 2r + 5 + r + 4r - 3 = 38
9r + 5 - 3 = 38
9r + 2 = 38
9r = 38 - 2
9r = 36
9r/9 = 36/9
r = 4cm
Done!
Y=1\2x.
hopes this helps you
Y-intercept, where the graph crosses y-axiss is 0. that means in the equation: y = mx + b
b = 0
the m, is slope. looking at the graph you can see the points on the line are connect up 4 right 1. rise/run = slope = 4
y = 4x
-(-5 - 6x) = 4 (5x +3)
Pretend that there is a -1 in front of the first bracket
-1(-5-6x)= 4(5x+3)
Mutiply the first bracket by -1
(-1)(-5)(-1)(-6x)= 5+6x
Mutiply the second bracket by 4
(4)(5x)(4)(3)= 20x+12
5+6x= 20x+12
move 20x to the other side
5+6x-20x= 20x-20x+12
5+6x-20x= 12
5-14x= 12
move 5 to the other side
sign changes from +5 to -5.
5-5-14x= 12-5
-14x=7
divide by -14
-14x/-14= 7/-14
x= -1/2
Answer: x= -1/2
