The slope would have to be -3
Answer:
slope = -4/5
y intercept = -4
Step-by-step explanation:
-5y = 4x+20
divide each side by -5
y = 4x/-5 + 20/-5
y = -4/5 x -4
it is in the form y = mx +b where m is the slope and b is the y intercept
m = -4/5 and b = -4
Answer: x = -9
Step-by-step explanation:
-10x - 10y = -10
when y = 10
-10x - 10(10) = -10
-10x - 100 = -10
Add 100 to each side
-10x = 90
Divide each side by -10
x = -9
-10(-9) - 10(10)
90 - 100 = -10
Answer:
If Susan bought 12 ounces that would equal to .75 pounds
Step-by-step explanation:
The standard equation of a circle:
(y-k)² + (x-h)² = R² (1), where R is the radius and h, k are the coordinates of the center.: C(h, k)
In the problem the coordinates of the center C(2,-1).
Replace in (1) h by 2 and k by -1:
(y+1)² + (x-2)² = 25
