Answer:
Y=2x - 3/4
Step-by-step explanation:
The slope is calculated by y-y over x-x. That equals 2. The. You put the x and y coordinates in to get the y intercept which is -3/4
145 will work. It is an odd number and is greater than 142 and is less than 156
142 < 145 < 156
Other numbers such as 143, 147, 149,151,153, 155 will work.
Answer:
Center ( 4 , -2) and r = 6
Step-by-step explanation:
x² - 8x + y² + 4y - 16 = 0
x² - 8x + y² + 4 y = 16
x²- 2*4x + y² + 2 *2y = 16
(x² - 2*4x + 16 ) - 16 + (y² + 2*2y + 4) -4 = 16
(x - 4)² + (y + 2)² = 16 + 16 + 4
(x - 4)² + (y -[-2])² = 36
(x- 4)² + ( y - [-2] )² = 6²
Compare with (x - h)²+ (y - k)² = r²
Center ( 4 , -2) and r = 6
-6/4 where -6 is your y value (six down) and 4 is your x value (four to the right)
1.5 cups x 7 days = 10.5 cups
(be ready, thisl come out ugly)
1 cup = 0.0625 gal
10.5 cups = 0.65625 gallons leaked per week
