The Answer is 7.5. I hope this helped you
Answer:
B
Step-by-step explanation:
put both sides under square root.
x^2 + y^2 = 64
sqrt ( x^2 + y^2 ) = sqrt(64)
x + y = 8
r = 8.
Answer:
Constant of variation: 1/4
Slope of the line: 1/4
Step-by-step explanation:
The constant of variation means the relationship between variables does not change. When we want to identify the constant of variation for an equation, it is helpful to refer to one of the following formulas: xy = k (inverse variation) or y/x = k (direct variation), where k is the constant of variation.
The slope formula states that m = (y2 -- y1) / (x2 -- x1). The slope formula can be read as "slope equals the second y coordinate minus the first y-coordinate over the second x-coordinate minus the first x-coordinate".
(-4 1/2) / (-2 2/3) =.....turn to improper fractions
(- 9/2) / (-8/3) =...when dividing fractions, flip what u r dividing by, then multiply
-9/2 * -3/8 =
27/16 =
1 11/16 <==
Answer:
The answer would be D, 0 < x < 4
Step-by-step explanation:
Because Domian is left to right of a function, so left to right would be 0 to 4
