Find x if the angles are complementary
Answer:
B
Step-by-step explanation:
Complementary means that two angles add up to 90°.
We can make an equation to resemble the problem and solve for x.
(4x - 2) + (11x + 17) = 90
15x + 15 = 90
15x = 75
x = 5

In math class, the girl to boy ratio is 8 to 6. if there are 24 girls in the class how many boys are there?
Answer:
18
Step-by-step explanation:
We know that the girl to boy ratio is 8:6 and we are told that there are 24 girls.
We multiply 8 by 3 to give us 24, so if we multiply by 3 on one side we must multiply by 3 on the other side.
This gives us a final answer of 24:18, so there are 18 boys in the class.

Find the vertex of the graph of the quadratic function. Determine whether the graph opens upward or downward, find the y-intercept, and sketch the graph. f(x) = -x- 8x-7
The answer is : (-4, 9)
The given function is:
f(x) = -x^2 - 8x - 7
To find the vertex of the parabola, we need to complete the square as follows:
f(x) = -(x^2 + 8x) - 7
= -(x^2 + 8x + 16) + 16 - 7
= -(x + 4)^2 + 9
Hence, the vertex is (-4, 9).
Since the coefficient of x^2 is negative, the parabola opens downward.
To find the y-intercept, we set x = 0:
f(0) = -0^2 - 8(0) - 7 = -7
Therefore, the y-intercept is (0, -7).
To sketch the graph, we plot the vertex (-4, 9) and the y-intercept (0, -7). Since the parabola opens downward, it will have a maximum value at the vertex. We can also plot a few other points by choosing values of x and calculating the corresponding values of y.
Therefore, the vertex is (-4, 9).

Pleasee help I'm stuck on this question! At Cheng's Bike Rentals, it costs $23 to rent a bike for 4 hours. How many hours of bike use does a customer get per dollar? if necessary round to the nesrest hundredth.
Answer:
[tex]\huge\boxed{\text{0.17 hours}}[/tex]
Step-by-step explanation:
We can create two ratios to find how long you can use a bike for one dollar.
Let's set up a ratio in the form [tex]\frac{cost}{hours}[/tex]
We know it costs $23 to ride for 4 hours, so we can make the fraction [tex]\frac{23}{4}[/tex].
We also know that for $1, we'll have some unknown time for the bike. We can represent this as [tex]\frac{1}{x}[/tex].
Since the constant of proportionality has to be the same, we can set these two ratios equal to each other.
[tex]\frac{23}{4}=\frac{1}{x}[/tex]
We can now solve for x by cross multiplying.
[tex]1 \cdot 4 = 4\\\\4 \div 32 \approx 0.17[/tex]
So $1 will get you around 0.17 hours of bike time.
Hope this helped!

B. Plane
C. Angle

7-7+16x-12x-6+x=12x-13x-12
Answer:
x = −1
Step-by-step explanation:
Answer:
x = -1
Step-by-step explanation:
7 - 7 + 16x - 12x - 6 + x = 12x - 13x - 12
Combine like terms
−6 + 5x = -x - 12
Add x to both sides
6x -6 = -12
Add -6 to both sides
6x = -6
Divide 6 to both sides
6x/6 = -6/6
x = -1

Ast week, Shelly rode her bike a total of 30 miles over a three-day period. On the second day, she rode 4 5 the distance she rode on the first day. On the third day, she rode 3 2 the distance she rode on the second day. How many miles did Shelly ride on each day? Select your answers from the drop-down lists. On the first day, Shelly rode miles. On the second day, Shelly rode miles. On the third day, Shelly rode miles.
Answer: On the first day, Shelly rode 10 miles on first day.
On the second day, Shelly rode 8 miles.
On the third day, Shelly rode 12 miles.
Step-by-step explanation:
Let x = distance rod eon first day.
Shelly rode her bike a total of 30 miles over a three-day period.
Then as per given,
Distance rode on second day = [tex]\dfrac45x[/tex]
Distance rode on third day [tex]=\dfrac32\times\text{ Distance rode on second day}[/tex]
[tex]=\dfrac32\times\dfrac45x=\dfrac{6}{5}x[/tex]
Total distance rode = [tex]x+\dfrac45 x+\dfrac65x=30[/tex]
[tex]\Rightarrow\ \dfrac{5x+4x+6x}{5}=30\\\\\Rightarrow\ \dfrac{15x}{5}=30\\\\\Rightarrow\ 3x=30\\\\\Rightarrow\ x=\dfrac{30}{3}\\\\\Rightarrow\ x=10[/tex]
Hence, She rode 10 miles on first day.
Distance rode on second day = [tex]\dfrac45\times10=4\times2=8\text{ miles}[/tex]
Distance rode on third day [tex]=\dfrac{3}{2}\times8=3\times4=12\text{ miles}[/tex]
A box holds a white button, a brown button and a black button. What is the probability of picking a white button then without replacing it, picking a brown button on the second pick?(decimal)
Answer:
1/5
In decimal = 0.2
Step-by-step explanation:
A box holds a white button, a brown button and a black button.
Hence:
Number of white button= 1
Number of brown button= 1
Number of black button= 1
Total number of buttons = 3
The probability of picking a white button then without replacing it, picking a brown button on the second pick is :
= P(White) × P(Brown) [ without replacement]
= 1/3 × 1/2
= 1/5
In decimal = 0.2

Step-by-step explanation:
a resort hotel charges 12.5% in taxes. Additionally they charge a $25 resort fee each day. (The resort fee is not subject to sales tax.)
The following functions represents the situation:
f (a) = 1.125a
g (b) = b + 25
a. Match the following to their description
1. ___ a A. The cost of the hotel room and sales tax, but without the resort fee
2. ___ b B. The cost of the hotel room without sales tax or the resort fee.
3. ___ f (a) C. The cost of the hotel room, with sales tax and the resort fee.
4. ___ g (b)
Answer:
We know that the hotel charges 12.5% in taxes (or 0.125 in decimal form).
Then if the initial cost of the hotel, without taxes, is a, the price with taxes will be:
f(a) = a + 0.125*a = 1.125*a
And the hotel also charges a fee of $25 for each day (that is not subject to taxes) then if the total cost, with taxes, is b, the actual cost will be:
g(b) = b + 25.
Then:
a = The cost of the hotel room without sales tax or the resort fee.
f(a) and b= The cost of the hotel room and sales tax, but without the resort fee
g(b) = The cost of the hotel room, with sales tax and the resort fee.

The perimeter of a rectangle is 8(2x+1) inches. The length of the sides of the rectangle are 3x+4 inches and 4x+3 inches. Find the length of each side of the rectangle. (You will have two answers.)
Answer:
The lengths of the sides of the rectangle are 13 inches and 15 inches
Step-by-step explanation:
The perimeter of a rectangle
Given the two sides of a rectangle a and b. The perimeter of the rectangle is:
[tex]P=2(a+b)[/tex]
We are given the perimeter of a rectangle as:
[tex]P=8(2x+1)[/tex]
And each side has a length of 3x+4 and 4x+3. Calculating the perimeter:
[tex]P=2(3x+4+4x+3)=2(7x+7)[/tex]
We set up the equation:
[tex]8(2x+1)=2(7x+7)[/tex]
Dividing by 2:
[tex]4(2x+1)=7x+7[/tex]
Operating:
[tex]8x+4=7x+7[/tex]
Subtracting 7x:
[tex]x+4=7[/tex]
Subtracting 4:
x=3
The length of each side is:
3x+4=3*3+4=13
4x+3=4*3+3=15
The lengths of the sides of the rectangle are 13 inches and 15 inches

determine the range of the graph shown
A). [0,8]
B).(0,8)
C).[0,13]
D).[0,12]
Explanation:
The lowest point occurs when y = 0.
The highest point occurs when y = 12.
The range is therefore [tex]0 \le y \le 12[/tex] which converts to [tex][0,12][/tex] which is interval notation. The square brackets tell us to include the endpoints. So we're saying that y can be anything between 0 and 12, including both endpoints.
The range is the set of all possible y outputs of a function.

PLEASE HURRY ILL MAKE BRAINLIEST!!!!!
Answer:
the answer is y= 4x-6
Step-by-step explanation:
props to the person that asked the question <3
Option (c) is correct.
The equation of the line is y = 4x -6, when the coordinate system with the y-axis is numbered from negative 6 to 6 in increments of 2 and the x-axis is numbered from negative 4 to 4 in increments of 2.
What is the equation of a line?
A straight line's general equation is y = mx + c, where m denotes the gradient and y = c denotes the point at which the line crosses the y-axis. On the y-axis, this value c is referred to as the intercept. Key Concept.
Y = mx + c represents the equation of a straight line with gradient m and intercept c on the y-axis.
The given coordinates are:
(x,y) = (0,-6)
(x,y) = (1,-2)
(x,y) = (2,2)
So, when we substitute the values of x and y as given above in the equation: y = 4x -6, we get the same result of x and y.\
Hence, The equation of the line is y = 4x -6, when the coordinate system with the y-axis is numbered from negative 6 to 6 in increments of 2 and the x-axis is numbered from negative 4 to 4 in increments of 2.
