Answer:
y = -x^2
Step-by-step explanation:
First off you can tell that the graph represents a negative,
nonlinear function due to the direction of the 2 "lines" from
point (0,0). This simply means you can eliminate the graph
representing y = 2x^2 as one of the choices. Now as this is
squared function (^2) you can tell that every x value should be
squared to receive the y value. Here I am suggesting a simple
- x^2 to be defined for the graph. Take x = 1 as the first
example. If x is squared then y is equal to 1 as well. This is
represented as two coordinates on the graph, when the y value
is negative and when the y value is positive. Now say x = 2.
When x is squared y = 4, represented by the graph as two
points as well, when y is a negative value of 4 and a positive.
This shows that the graph resembles the function -x^2 (y = -x^2)
Answer:
The graph in the attached figure
Step-by-step explanation:
Let
x-----> the number of pints
y----> the number of servings
For x=3 pints, y=2 servings
This is a proportional variation
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form 
or 
so
The linear equation is equal to

Answer:
60.2 miles.
Step-by-step explanation:
43 / 2.5 = 17.2 << unit rate
17.2 x 3.5 = 60.2
Answer:
3 lol
Step-by-step explanation:
Answer:
1) 22.5 A
2) 112 B
3) 430 L
4) 576 P
5) 486 L
6) 624 S
Code is A B L P L S
Step-by-step explanation:
1) Area of a triangle = 1/2 * base * height = 1/2 *5*9 = 22.5
2) Area of a parallelogram = base x height = 14 x 8 = 112
3) Area of a rectangular prism = 2(length * width) + 2*(length + height) + 2 *(length *height)
= 2(15x7 + 15*5 + 7*5)
= 2(105 + 75 + 35)
= 2 * 215
= 430
4) Volume of a triangular prism = 1/2 * base * length * height
= 1/2 * 8 * 16 * 9
= 576
5) A cube has six surfaces. Each surface has an area of s x s where s is the length of each side. In this case, each side has area of 9x9 = 81. Total surface area = 6 x 81 = 486 and that is the paper required
6) The trailer is a rectangular prism so its volume = length x width x height = 13 6 x 8 = 624
Now you have to look at each value and see which letter it corresponds to. For example answer 1) is 22.5 which lies between 0-100 so it gets letter A, answer (2) is 112 which lies in the range 101-200 so it gets the letter B and so on
