It looks to be D but if you still need help I'd recommend checking out Desmos sure it is a graphing calculator but it may be easier to understand it with that.
Answer:
Step-by-step explanation:
Let
y------> the total cost
c-----> the number of topping
we know that
----> linear equation that represent the situation
The two ratios that are equivalent to, 2:9 are 18:81 and 12:54. Hope it helps
Answer:
a. 18 cm
Step-by-step explanation:
We are given that a circle has an area of 324π cm2. We are required to determine its radius. The formula for the area of a circle with radius r units is;
We plug in the area given and solve for r;
The radius of the circle is 18 cm
Answer:
y = 0
Step-by-step explanation:
A parallelogram is a quadrilateral with opposite sides parallel. Then segment CD must be parallel to AB, and CB must be parallel to DA. Two different segments are parallel if they have the same slope.
slope of DA = (yA - yD)/(xA - xD) = (4 - 2)/(1 - (-1)) = 1
slope of CB = (yB - yC)/(xB - xC) = (2 - yC)/(1 - (-1)) = 1
(2 - yC) = 2 * 1
2 - 2 = yC
0 = yC
Note: coordinates of A are (xA, yA), of B are (xB, yB), of C are (xC, yC) and of D are (xD, yD)
