Answer: D) 39/50
Step-by-step explanation:
-3/5 x 13/10 = -39/50
-39/50 + 39/50 = -78/50
-39/50 + -6/5 = -33/50
-39/50 + 39/50 = 0
0=0√
Draw a graph that joins the points (100, 120) and (50, 95) and has a slope = 2
Draw a graph that joins the points (120, 100) and (95, 50) and has a slope = 2
Draw a graph that joins the points (120, 100) and (95, 50) and has a slope = 0.50
Answer:
The correct answer is A. Draw a graph that joins the points (100, 120) and (50, 95) and has a slope = 0.50
Step-by-step explanation:
1. Let's review the information given to us for solving the question:
Total of megabytes of date used = x
Total monthly charges = y
x₁ = 50 Megabytes, x₂ = 100 Megabytes
y₁ = US$ 95, y₂ = US$ 120
2. Let's find out the best description of the steps to draw the graph and the slope.
Slope = (y₂ - y₁)/ (x ₂- x₁)
Slope = 120 - 95/ 100 - 50
Slope = 25/50 = 1/2 = 0.50
Remember that the coordinates of the points in the line are written this way:
(x, y) ⇒ (Total of megabytes of date used, Total monthly charges)
The correct answer is A. Draw a graph that joins the points (100, 120) and (50, 95) and has a slope = 0.50

Answer:
12
Step-by-step explanation:
Assuming that the shape of the playground is rectangular, we know that the area of a rectangle is length x width.
Let the length = x
width = x + 5
x(x + 5) = 204
x² + 5x = 204
x² + 5x - 204 = 0
(x + 17)(x - 12) = 0
x = -17 and x = 12
However, since x represents the length of the playground, length cannot be negative. The only value possible is x = 12.
Therefore, the playground has a length of 12 yd and a width of 12 + 5 = 17 yd.
Answer:
length = 17 yd, width = 12 yd
