From the given information,
Carly earns $15 for each thirty-minute session and $25 for each sixty-minute session
Also,
She earned $230 this past weekend and had x thirty-minute sessions and x - 2 sixty-minute sessions

Two point form is a method for finding the equation of a function if two of its points are known. If (x1, y1) and (x2, y2) are the two points then equation of the function is given as-
(y - y1) = {(y1 - y2)/ (x1 - x2)} (x - x1)
Here, we are given that h(7) = -10 and h(-2) = 8
This, means that (7, -10) and (-2, 8) will satisfy the given function
Since, we have two points, we will use the two point form to find the equation of function h.
Substituting, x1 = 7, y1 = -10, x2 = -2 and y2 = 8 in the two point form equation we get-
( y - 7) = {(-10 - 8) / (7 + 2)} (x + 10)
y - 7 = (-18/9) (x + 10)
y - 7 = -2(x + 10)
y - 7 = -2x -20
y = -2x -20 + 7
y = -2x -13
Thus, h(x) = -2x -13
Hence, h(3) = -2(3) -13
= -6 -13
= -19
Therefore, h(3) = -19

Answer:
Any line with a slope of -5/8 would be parallel to this line.
Step-by-step explanation:
First write this in the slope intercept form of a line
y = mx + b. The number before the x will be the slope.

The given expression expressed in the form (x+A)^2+B is (x - 6)² + 65
A = -6 and B = 65
Completing the squareFrom the question, we are to express the given expression in the form (x + A)^2+B by completing the square
The given expression is
x² -12x + 101
Using the completing the square method
x² -12x + 101
Divide the coefficient of x by 2 and then square it
The coefficient of x is -12
Dividing by 2, we get
-12/2 = -6
Squaring
(-6)²
Now, add and subtract this value from the expression
x² -12x + (-6)² + 101 - (-6)²
Then, we can write that
(x - 6)² + 101 - (-6)²
(x - 6)² + 101 - 36
(x - 6)² + 65
Thus,
The given expression expressed in the form (x+A)^2+B is (x - 6)² + 65
By comparison,

Carlos and Shawn are selling fruit for a school fundraiser. Customers can buy small boxes of oranges and large boxes of oranges. Carlos sold 13 small boxes of oranges and 5 large boxes of oranges for a total of $133. Shawn sold 10 small boxes of oranges and 8 large boxes of oranges for a total of $148. Find the cost of each of one small box of oranges and one large box of oranges.
Answer: The cost of one small box of oranges is $6, while the cost of one large box of oranges is $11.
Step-by-step explanation:
First, set x for the cost of one small box of oranges in dollars, and y for the cost of one large box of oranges in dollars.
Hence, the equations will be:
[tex]13x+5y=133[/tex]
[tex]10x+8y=148[/tex]
Then solve for the equations using the method of elimination. In order to eliminate one of the variables, you need to make the coefficients the same. So, we can multiply the first equation by 8 and the second equation by 5. That would make the equations:
[tex]104x+40y=1064[/tex]
[tex]50x+40y=740[/tex]
Then you can eliminate the y by subtracting.
[tex]54x = 324[/tex]
Then divide by 54 on both sides.
[tex]x=6[/tex]
Now that x is solved, solve for y by substituting for x.
[tex]13(6) + 5y = 133[/tex]
[tex]5y+78=133[/tex]
[tex]5y=55[/tex]
[tex]y=11[/tex]
So, x=6 and y=11.

g(x) = (x – 2)2 + k
g(x) = (x + 8)2 + k
g(x) = (x – h)2 – 5
g(x) = (x – h)2 – 15
If the axis of symmetry for g(x) is located 2 units to the right of the origin, then the function g(x) = (x-2)2 +k describes this relationship. The best choice would be A in this case.
What exactly is a function?The function is a statement, rule, or law that specifies the connection between one variable and another variable. It does this by comparing and contrasting the two variables.
Functions may be found almost everywhere, and creating links between physical objects requires their use.
Given
The answer to the question f(x) is.
(x+3)^2 -10
The left side by three units serves as the axis of symmetry for the function f(x).
The axis of symmetry for g(x) may be found five units to the right of where f is located (x).
If this is the case, the axis of symmetry for g(x) will be found 2 units to the right of the origin.

motorcycle maker, says that it expects to build 312,000 motorcycles this year, up from 290,700 last year. Find the percent of increase in production.
Explanation:
A = last year's value = 290,700
B = this year's value = 312,000
C = change in values
C = B - A
C = 312,000 - 290,700 = 21,300
The positive result shows the increase of 21,300 more motorcycles made this year, compared to last year. A negative C value would represent a percent decrease.
Divide this change over the original.
C/A = (21,300)/(290,700) = 0.07327141382869
which is approximate. Let's say we rounded to four decimal places to get 0.0733 which then converts to the percentage 7.33%

Find a linear equation whose graph is the straight line with the given properties.
through (1, 4) with slope 6
Answer:
y = 6x - 2
Step-by-step explanation:
We will use the slope-intercept form of a line to help us. We know the slope, we need to determine the y-intercept. To find this, we need an x and y on the line and the slope. Fortunately, they have given us all of the information. An ordered pair is in the form (x,y) So we will use x = 1 and y = 4 from the point they have given us (1,4) They have also given us the slope of 6. We will plug this all into our equation and solve for b the y-intercept.
y = mx + b
4 = 6(1) + b
4 = 6 + b Subtract 6 from both sides of the equation.
-2 = b
Now, write the equation
y = mx + b
y = 6x -2
Graph the following figure in the coordinate plane. Find the perimeter. X(0,1), Y(4, -2), Z(-5, -2)

How to graph the figure in the coordinate plane and find the perimeter?The coordinates are given as
X(0,1), Y(4, -2), Z(-5, -2)
Next, we plot the above coordinates on a coordinate plane
See attachment for the plot of the coordinates on a coordinate plane
Next, we calculate the distance between the points using
d = √(x2 - x1)^2 + (y2 - y1)^2
So, we have
XY = √(0 - 4)^2 + (1 + 2)^2 = 5
XZ = √(0 + 5)^2 + (1 + 2)^2 = √14
YZ = √(4 + 5)^2 + (-2 + 2)^2 = 3
The perimeter is calculated as
P = XY + XZ + YZ
So, we have
P = 5 + √14 + 3

P = 8 + √14

You want the product of 6+3i and its conjugate.
ConjugateThe conjugate of a complex number is created by reversing the sign of the imaginary part.
(6 +3i)* = 6 -3i
Product of squaresThe product of a complex number and its conjugate is recognizable as the factored form of the difference of squares:
(6 +3i)(6 -3i) = (6)² -(3i)²
Of course, i² = -1, so this becomes ...
6² -(3i)² = 36 -(-9) = 36 +9 = 45
The product of 6+3i and its conjugate is 45.

Trying to find the inverse of a the function:
s(t) = - 85 - 7t
--------
10
The inverse function of the function is s'1(t) = 1/7(10t + 85)
What are inverse functions?Inverse functions are the opposite of an original equation.
This means that for a function f(x), the inverse of the function f(x) is f-(x); it also represents the opposite function
How to determine the inverse functions?The function f(x) is given as
s(t) = -(85 - 7t)/10
As a general rule, we start by writing s(t) as a variable (say s(t) = s).
So, the equation of the function becomes
s = -(85 - 7t)/10
The next step is to switch/swap the positions of s and t in the above equation s = -(85 - 7t)/10
The equation becomes
t = -(85 - 7s)/10
The next step is to make s the subject of the formula in the above equation t = -(85 - 7s)/10
The equation becomes
10t = -(85 - 7s)
Open the bracket
10t = -85 + 7s
So, we have
7s = 10t + 85
Divide by 7
s = 1/7(10t + 85)
Express as an inverse function
s'1(t) = 1/7(10t + 85)
Hence, the inverse function of the function is s'1(t) = 1/7(10t + 85)
