We are looking for the number of children than can ride safely with 4 adults.
Since 4 adults are already seated, A = 4.
We substitute 4 for A in the inequality and solve for C.
150A + 100C + 200 ≤ 1500
150(4) + 100C + 200 ≤ 1500
600 + 100C + 200 ≤ 1500
100C + 800 ≤ 1500
100C ≤ 700

Which statement is true about the effects of the transformations on the graph of function f to obtain the graph of function g.
g(x) = f(x) + 4
A.
The graph of function f is shifted up 4 units.
B.
The graph of function f is compressed vertically toward the x-axis by a factor of 4.
C.
The graph of function f is stretched vertically away from the x-axis by a factor of 4.
D.
The graph of function f is shifted down 4 units.
Answer:
A
Step-by-step explanation:
The constant 4 is positive so the graph is shifted up by 4 units. If it was instead -4, then the graph would have been shifted down 4 units
How do I solve 6x-15+52=11x-12?
Answer:
x = 49/5 (fraction)
Step-by-step explanation:
Add and subtract the numbers: -15 + 52 =37
6x+37=11x-12
Subtract 37 on both sides:
6x+37-37=11x-12-37
Simplify:
6x=11x-49
Subtract 11x from both sides:
6x-11x=11x-49-11x
Simplify:
-5x=-49
Divide both sides by -5
-5x/-5=-49/-5
= 49/5

Answer:
23°
Step-by-step explanation:
There is not enough information given in this diagram to provide values for the marked angles. In order to solve the problem, we must assume some relation between those angles.
If they are equal, then ...
9x -22 = 6x -7
3x = 15 . . . . . . . . . . add 22-6x to both sides
x = 5 . . . . . . . . divide both sides by 3
m∠ABD = (9x -22)° = (9·5 -22)° = 23°
Iris paid $120.00 for a winter coat. She saved
25% off the original price.
What was the original price of the coat?
Answer:
$160, or answer A
Step-by-step explanation:
If 120 is 25% of the original, or 0.25 of the original(We will call it x), then 120 is 0.75x.
Form an equation like this: 0.75x=120
Turn this into fractions: 3/4x=120/1.
Divide by 3/4 on both sides.
x = 120/1 * 4/3
Simplify to get: 40/1 * 4/1
Multiply to get: 160
The original price of the coat is $160.
What is a percentage?A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.
Given. Iris paid $120 for a winter coat.
She saved 25% off the original price .
We have 4 options $160, $150, $145 and $30.
Now let $160 is the original price,
25% of 160 = 160 x 25 / 100
= $40
Therefore, the original price of the coat is $160.

B , C , D are polygons.1. In this figure, the unshaded region represents a painting and the shaded region represents a frame around the painting. All angles are night angles 6 in. 10 in 9.5 in 13.5 in (a) What is the area of the painting? Show your work (b) What is the area of the frame? Show your work Answer:
The area of a shape is the amount of space on the shape
The area of the painting is 60 square inchesThe area of the frame is 60.25 square inchesHow to determine the area of the paintingFrom the question, the dimension of the painting is 6 inches by 10 inches
So, the area of the painting is:
Area = 6 * 10
Area = 60 square inches
Hence, the area of the painting is 60 square inches
How to determine the area of the frameFrom the question, the dimension of the picture is 9.5 inches by 13.5 inches
So, the area of the picture is:
Area = 9.5 * 13.5
Area = 128.25 square inches
The area of the frame is the difference between the area of the picture and the painting.
So, we have:
Frame = 128.25 - 60
Frame = 68.25
Hence, the area of the frame is 60.25 square inches

The variables y and x have a proportional relationship, and y = 7 when x = 2. What is the value of y when x = 5? Enter your answer as a decimal in the box.
Answer:
y = 17.5
Step-by-step explanation:
A relationship between two variables, x, and y, represent a direct variation if it can be expressed in the form y/x = k or y = kx
Find the value of the constant k
we have:
y = 7 and x = 2
substitute
7/2 = k
k = 3.5
Thus, the equation is equal to
y = 3.5x
Find the value of y when x = 5
substitute in the equation
y = 3.5(5) = 17.5
Or we can put as:
y = 7 * 5 /2
Calculate the product or quotient: y = 35/2
Answer = 17.5
[RevyBreeze]
Answer:
y = 17.5
Step-by-step explanation:
If y is proportional to x, then:
[tex]y = kx[/tex] (for some constant k)
Given y = 7 when x = 2:
⇒ 7 = 2k
⇒ k = 3.5
Therefore, [tex]y=3.5x[/tex]
So when x = 5:
⇒ y = 3.5 x 5
⇒ y = 17.5

Which describes the slope of the line in the graph?
A)
zero
B)
positive
negative
D)
undefined
Answer:
C. Negative
Step-by-step explanation:
The line is not horizontal or vertical, therefore we the slope cannot be zero or undefined.
This leaves us with either positive or negative...
A positive slope goes from the lower left corner (Quadrant 3) of the graph up to the upper right (Quadrant 1).
A negative slope goes from the upper left corner (Quadrant 2) of the graph down to the lower right (Quadrant 4).
Since this line goes from the upper left corner to the lower right, it has a negative slope
