8x + 6y = 28
9x + 3y = 39
Set to equal y.
8x + 6y = 28
6y = -8x + 28
y = -8/6x + 28/6
y = -4/3x + 14/3
9x + 3y = 39
3y = -9x + 39
y = -9/3x + 39/3
y = -3x + 13
Set equal to each other.
-4/3x + 14/3 = -3x + 13
Combine like terms.
5/3x = 25/3
Multiply by 3/5
x = 5
Plug x in.
y = -3(5) + 13
y = -15 + 13
y = -2
(5, -2)
2.
-2x - 9y = -3
-7x - 9y= -33
Set equal to y.
-2x - 9y = -3
-9y = 2x - 3
y = -2/9x + 3/9
y = -2/9x + 1/3
-7x - 9y= -33
-9y = 7x - 33
y = -7/9x + 33/9
y = -7/9x + 11/3
Set equal to each other
-2/9x + 1/3 = -2/9x + 1/3
0 = 0

The estimated total cost, y, of a child's toy is partially based on the number of batteries used, x. The cost per battery is $0.50. They toy itself costs $15. Which equation represent the situation?
a
y = 0.50x - 15
b
y = 15x - 0.50
c
y = 15x + 0.50
d
y = 0.50x + 15
Answer:
D: 0.50x+15
Step-by-step explanation:
batteries used(each)- x, so you add the x in front of 0.50 representing multiplication between the #
you are doing total cost so you are doing addition (obvously) then its a plain $15 for the toy itself therefore,
y=0.50x+15 (hope this made sense)

Find g(6) when g(x) = x2-5
Answer:
g(6) = 31
Step-by-step explanation:
If g(x) = x^2 - 5, that means to solve for g(6) you just have to replace the x in the equation with 6.
g(6) = 6^2 - 5
g(6) = 36 - 5
g(6) = 31

The variables are x and y, the coefficients are -2 and 3/4, and the constant is 3/7 in the given algebraic expression 3x/4 − 2y + 3/7.
What is the algebraic expression?Algebraic expressions are mathematical statements that comprise at least two variables or integers.
What are arithmetic operations?Arithmetic operations can also be described via subtracting, dividing, and multiplying built-in functions.
We have been the given algebraic expression as :
⇒ 3x/4 − 2y + 3/7
Here variables are x and y
The coefficients are -2 and 3/4
The constant is 3/7
Therefore, the variables are x and y, the coefficients are -2 and 3/4, and the constant is 3/7 in the given algebraic expression 3x/4 − 2y + 3/7.

What is the equation, in slope-intercept form, of the line that passes through (0, 6) and has a slope of 4 (5 points)
Answer: y=4x+6
Step-by-step explanation: you replace the variables in the equation with the variables in the point given to find b.
Answer:
[tex]y = 4x+6[/tex]
Step-by-step explanation:
Equation of a line
The equation of a line can be written in the form:
[tex]y = mx+b[/tex]
Where m is the slope of the line and b is the y-intercept. We are given the value of m=4, thus the equation becomes:
[tex]y = 4x+b[/tex]
To find the value of b, we use the point (0,6):
[tex]6=4*0+b[/tex]
Solving:
[tex]b=6[/tex]
Thus, the equation in slope-intercept form of the required line is
[tex]\boxed{y = 4x+6}[/tex]

On a ferris wheel, Sarah observes that it takes 45 seconds for her chair to complete a full revolution. Her chair is 30 feet from the axle of the ferris wheel.
To the nearest hundreth, Sarah's angular velocity is _____ radians per minute.
Answer:
The angular velocity is 8.38 radians per minute
Step-by-step explanation:
From the question,
It takes 45 seconds to complete a full revolution,
That is, 1rev/45secs
First, we will convert this to revolutions per minute (rev/min)
1rev/45secs = [tex]\frac{1 revolutions}{45 seconds} \times \frac{60seconds}{1minute}[/tex]
= 4/3 rev/min
Now, we will convert this to radians per minute (rad/min)
1 revolutions = 2π rad
4/3 rev/min = [tex]\frac{\frac{4}{3} rev}{min} \times \frac{2\pi rad}{1 rev}[/tex]
= 8.38 rad/min
Hence, the angular velocity is 8.38 radians per minute

A teacher spent $240.75 including tax on school supplies. If the tax rate is 7%, find the price of the supplies before taxes. PLEASE HELP will mark as Brainliest
Answer:
$225.
Step-by-step explanation:
Let the price before taxes be x dollars. Then we have the equation:
x + 7% of x = 240.75
x + 0.07x = 240.75
1.07x = 240.75
x = 240.75/1.07
= $225.
The difference between the areas of the figures is less than 4.
An absolute value inequality that represents this situation is ___
The solution of the inequality is ___
Answer:
1. |40 – 4x| < 4
2. 9 < x < 11
Step-by-step explanation:
We'll begin by calculating the area of each figure. This can be obtained as follow:
For triangle:
Area = ½ × base × height
Base = 8
Height = 6
Area =?
Area = ½ × 8 × 6
Area = 4 × 6
Area = 24
For Rectangle:
Area = length × breadth
Length = x – 4
Breadth = 4
Area =?
Area = (x – 4) × 4
Area = 4x – 16
Summary:
Area of triangle (Aₜ) = 24
Area of rectangle (Aᵣ) = 4x – 16
1. Writing an absolute value for the inequality.
From the question given above, we were told that the difference between the areas of the figures is less than 4. This can be written as:
Aₜ – Aᵣ < 4
Area of triangle (Aₜ) = 24
Area of rectangle (Aᵣ) = 4x – 16
24 – (4x – 16) < 4
Simplify
24 – (4x – 16) < 4
Clear bracket
24 – 4x + 16 < 4
24 + 16 – 4x < 4
40 – 4x < 4
Thus, we can write the absolute value for the above inequality as:
|40 – 4x| < 4
2. Determination of the solution of the inequality.
This is illustrated below:
|40 – 4x| < 4
Thus the above equation can be written as
– 4 < 40 – 4x < 4
Subtract 40 from both side
– 4 – 40 < 40 – 4x – 40 < 4 –40
– 44 < – 4x < – 36
Divide through by –4
– 44/–4 < x < – 36/–4
11 > x > 9
Note: the inequality sign changed because we divided by a negative number
Thus, 11 > x > 9 becomes 9 < x < 11
Therefore, the solution to the inequality is 9 < x < 11
