A number between 60 & 65 ??
Answer:
Slope = 4
Step-by-step explanation:
The x-axis values to represent the number of correct answers.
The y-axis values to represent the number of points earned.
The points on the graph are: (17,68) , (20,80) and (24,96)
The slope(m) of the graph = change in y ÷ change in x
i.e
=
= 4
The equation of the straight line graph is;
y=4x
Answer:
add it up to see if it's 180
Answer:
x = 16
Step-by-step explanation:
Verticle angles are always congruent, so:
(8x + 15) = 143
Now, we can solve to isolate x:
8x + 15 - 15 = 143 - 15 (subtract 15 from both sides)
8x/8 = 128/8 (divide both sides by 8)
x = 16
You can always plug in the value of x to the original equation to check your answer:
8(16) + 15 = 143
