In the system of equations, x represents the, price to wash a car and y represents the price to wash an SUV.
If the system of equations is graphed in a coordinate plane, the coordinates (x, y) of the intersection of the two lines are the price of the car wash (x) and the price of the SUV wash (y)______.
x=12 and y = 18
x+y = 12+18 = 30
The total cost of 1 car and 1 SUV is $_30____.
5x+4y = 5(12)+4(18) = 60+ 72 =132
The total earnings for hour 3 are $_132_____.
Answer:
x: cost of 1 car wash
y: cost of each SUV wash
(12,18)
The total cost of 1 car and 1 SUV is $30
The total earnings for hour 3 are $132
Step-by-step explanation:
4x + 2y = 84
y = 42 - 2x
3x + 5y = 126
3x + 210 - 10x = 126
7x = 84
x = 12
y = 42 - 2(12) = 18
1 car and 1 SUV
12 + 18 = 30
For 3 hours:
5x + 4y
5(12) + 4(18)
132

Line segments AB and BC are tangents to Circle P. What is the value of x?
a.117
b.73
c.107
d.146
Answer:
c. 107°
Step-by-step explanation:
In the figure attached, Circle P, segments AB and BC, and angle x are shown.
From circumscribed angle theorem, we know that angle ABC and angle x are supplementary, then:
x + 73° = 180°
x = 180° - 73°
x = 107°

Answer: Snail ≈ 96,551.7 hours, North American X-15 ≈ 0.6 hours
Step-by-step explanation:
All you have to do is divide how many miles they go an hour by the total number of miles, which is 2,800.
Part 1: Garden Snail
= [tex]\frac{2,800}{0.029}[/tex]
≈ 96,551.7
Part 2: North American X-15
= [tex]\frac{2,800}{4,520}[/tex]
≈ 0.6

The scatterplot that represents the monthly values of stock ABC can be approximated by a line with a positive slope represents positive correlation. The correct option is C.
What is correlation?The relationship between variables is described by correlation. It can be either strong or weak, as well as positive or negative.
Correlations show that there is a relationship between two variables, but one does not always cause the other to change.
A positive correlation indicates that as one variable increases, so does the other.
In this case, the scatterplot of the monthly values of stock ABC can be approximated by a line with a positive slope, indicating that as the stock's value increases over time, so does the corresponding month. As a result, it is a positive correlation.
Thus, the correct option is C.

If a system of linear equations has one solution, what does this mean about the two lines?
A. The same line
B. Parallel lines
C. Intersecting lines
Answer:
It means two lines intersected.
C is correct
Hope this helps!
:)
If a system of linear equations has one solution, this means that the lines are intersecting lines
Intersecting lines are lines that meet at a point.
For parallel lines, they do not meet at any point. Hence the system of equation formed by these lines does not have a solution
For two intersecting lines, the equation of both lines can be equated to get the unknown variable. This unknown variable will serve as the solution to the system of equation
Hence If a system of linear equations has one solution, this means that the lines are intersecting lines

Madison received a share of $4230 for a fishing competition. She deposited it in the bank and left it for 3 years accumulating simple interest at 4.2%. Find her new balance in the bank after 3 years.
Answer:
$4785.68
Step-by-step explanation:
Original amount: $4230
Interest for 1 year: 4.2%
First year;
[tex]4230 + (4230 \times \frac{4.2}{100}) \\ = 4230 + 177.66 \\ = 4407.66[/tex]
Second year;
[tex]4407.66 + (4407.66 \times \frac{4.2}{100} ) \\ = 4407.66 + 185.12172 \\ = 4592.78172[/tex]
Third year (total balance after 3 years);
[tex]4592.78172 + (4592.78172 \times \frac{4.2}{100} ) \\ = 4592.78172 + 192.89683224 \\ =4785.67855224[/tex]

the total amount of fiber (in grams) in a package containing x apples and y oranges is given by the equation 5x + 10y = 110. is it possible for the package to contain 15 apples? EXPLAIN
Answer:
Step-by-step explanation:
The y intercept is the value of y when x = 0. Similarly, the x intercept is the value of x when y = 0. To find each of these, we separate the equation as shown in the attached image. After solving for x and y, we find that the y intercept is 11 and the x intercept is 22. For part e, we substitute 15 in for x. So instead of putting x in the equation, we will put 15 and solve for y. After solving, we see that y will equal 3.5. However, since we cannot have a "half apple" in the package, we see that it is not possible to have 15 apples in the package.
The volume of a cube is 64 cubic inches. Which expression represents s, the length of a side of the cube?
Recall the formula Cube V = 5
s=/64
CS= 64 +64 +64
S= 64
S=64.64.64
Answer:
Therefore the length of a side of a cube is [tex]\sqrt[3]{64}\ or\ 4[/tex]Step-by-step explanation:
The volume of a cube is expressed as L³ where L is the length of each side of the cube.
Given volume of a cube = 64in³
On substituting;
64 = L³
Taking the cube root of both sides to determine L we have;
[tex]\sqrt[3]{64} = (\sqrt[3]{L})^{3}\\\sqrt[3]{64} = L\\L=4[/tex]
Therefore the length of a side of a cube is [tex]\sqrt[3]{64}\ or\ 4[/tex]

Find the volume of the composite figure below:
5 in
8 in
6 in
10 in
Answer:
716in³
Step-by-step explanation:
The first step is to split the full prism into two, separate prisms. That means, we now have to find the volume of the half-a-cylinder, and the other base prism.
For the volume of the half-cylinder, we use the formula πr²h. That means, we do π·5·5·6, which is equal to around 471.24 cubic inches. However, we need to find the volume of half that cylinder, so we divide that answer by two. That should be about 235.62 cubic inches.
For the volume of the other prism, we simply have to do length times height times width, or 6·8·10. That is equal to 480 cubic inches, which is the volume of that prism.
To find the volume of the whole composite figure, you simple have to add the two underlined volumes above.
235.62+480= 715.62in³, or about 716in³.

What is the range of f(x)=(3/4)x-4
Answer:
Range of the function f(x) is all real numbers greater that -4, i.e., (-4,∞).
Step-by-step explanation:
The given function is f(x) = (3/4)x - 4
The value of (3/4)^x is greater than zero for any value of x. (3/4)^x > 0
Subtract 4 from both the sides. (3/4)^x - 4 > 0 - 4
f(x) > -4
The value of f(x) is greater than -4 for any value of x.
Therefore, the range of the function f(x) is all real numbers greater that -4. (-4,∞).

Answer:
x = 2
Step-by-step explanation:
(x² logₓ27) log₉x = x + 4
Use change of base formula.
x² (log 27 / log x) (log x / log 9) = x + 4
Simplify.
x² (log 27 / log 9) = x + 4
x² (log 3³ / log 3²) = x + 4
x² (3 log 3 / (2 log 3)) = x + 4
x² (3 / 2) = x + 4
3x² = 2x + 8
3x² − 2x − 8 = 0
(x − 2) (3x + 4) = 0
x = 2 or -4/3
Since x > 0, x = 2.

A Is congruent to A, B Is congruent to B, C Is congruent to C
Each triangle is a right triangle.
Each triangle is an isosceles triangle.
Answer:
A Is congruent to B and B Is congruent to C
Step-by-step explanation:
Given Figures A, B and C on a coordinate plane with the coordinates below:
Triangle A has points (1, -2), (3, -2), (3, -5).
Triangle B has points (4, 0), (6, 0), (6, -3).
Triangle C has points (4, 0), (6, 0), (6, 3).
The fact that each triangle is a right triangle only shows that the triangles are similar.
For any two shapes to be congruent, they must have in addition to the same shape, the same size.
Therefore, for Triangle A to be congruent to Triangle C, Triangle A must be congruent to Triangle B and Triangle B must be congruent to Triangle C.
