Answer! :
y = -2x + 5
Step by Step! :
slope intercept form:
y = mx + b
m being slope, b being the y intercept.
To find the slope, use this equation:
y^2 - y^1 / x^2 - x^1
Plug in your points.
(-1) - (7) / (3) - (-1)
-8 / 4
-2 is your slope! (y = -2x + b)
To solve for b, plug in any one of your points and solve for b. Let's use (3, -1)
-1 = -2(3) + b
-1 = -6 + b
5 = b
Your new equation is...
y = -2x + 5
Find the volume of 1 car by multiplying the length by the width by the height:
Volume of 1 car = 20 x 10 x 10 = 2000 cubic feet.
Now multiply the volume of 1 car by the total number of cars:
2000 x 100 = 200,000 cubic feet total.
So if I understand correctly, she had 7 1/8 pounds of birdseed and used 3/8 pound.
Convert the 7 1/8 to an improper fraction [(8*7)+1]/8 =57/8
57/8 - 3/8 = 54/8, which is 6 6/8 which reduces to 6 3/4 pounds left
If she had 7 pounds of birdseed and used 3/8 pounds, you need to find a common denominator to subtract if you can't do it in your head. 8 would be the common denominator, so:
56/8 - 3/8 = 53/8, which is 6 5/8 pounds left
-(-3) = +3
-6 + 3 is just removing 3 from -6 which leaves us with -3.
Answer:
a=-3
b=6
Step-by-step explanation:
equation 1: ax+6
equation 2: -3x+b
get the -3 from equation 2 and plug it into equation 1
get the 6 from equation 1 and plug it into equation 2
