First find the slope/rate of change of the table. Find the difference between the intervals of the x and y values of the table. Each time the x value decreases by 2 the y value decreases by 4. To find the rate of change divide the -4 by -2 to get 2 as the slope.
Set up an equation using values from the table to figure out the y intercept or b value.
-6=-4(2)+b
-6=-8+b. Add 8 from both sides
both sides to get b
2=b
The y intercept is (0,2)
The equation of the line is Y=2x+2
Plug in 0 for y into the lines equation to get the x intercept
0=2x+2
-2=2x. Divide by 2 to isolate x
-1=x
The x intercept is (-1,0)

Answer:
length = 30 feet and width = 20 feet
Step-by-step explanation:
Let l is length and b is width of a rectangular yard. The area of a rectangle is given by :
A = lb ..(1)
A rectangular yard has a length that is 10 feet longer than the width.
length, l = 10+b ...(2)
ATQ,
Put the value of l in equation (1),
Width can't be negative. The width is 20 feet.
Put the value of b is equation (2),
l = 10+20
l = 30 feet
Hence, the length and width are 30 feet and 20 feet.
So, for
T = 2 pi square m / k
the steps would be:
1) multiply by k
2) divide by <span>2π</span><span>
3) square</span>
Hope this is useful
Answer:
The answer is 90 square units.
Step-by-step explanation:
Volume = the length (3) x height (6) x width (5)
3 x 5 x 6 = 90
