Answer:
42
Step-by-step explanation:
(1 + 6) × 12 ÷ 2 = 42
area of a trapezoid:
Answer:
y = 4x - 7
Step-by-step explanation:
Given the following data;
Points (x, y) = (4, 9)
Slope, m = 4
To write the equation in point-slope form;
The equation of straight line is y = mx + c
Where;
m is the slope.
x and y are the points
c is the intercept.
First of all, we would find the intercept c;
9 = 4*4 + c
9 = 16 + c
c = 9 - 16
c = -7
Next, we write the equation in point-slope form;
m = 4 and c = -7
y = 4x - 7
Answer:
x = 6
Step-by-step explanation:
3x - 1 = 17
add 1 to both sides:
3x = 18
divide by 3:
x = 6
Answer:
9
Step-by-step explanation:
If you add them all together and divide by how many numbers there are, you will get the answer.
