f(x) = 3x - 5 and g(x) = 5x + 8. Find 3g(x) - 2f(x).
Answers
Answer:
9x + 34
Step-by-step explanation:
3g(x) - 2f(x); f(x) = 3x - 5 & g(x) = 5x + 8.
3(5x + 8) + - 2(3x - 5) (Plug g(x) & f(x) into equation)
15x + 24 + - 6x + 10 (Use distributive property)
9x + 34 (Combine like terms) - This is as much as it can be simplified.

its asking you to find the slope of the given lines by using the points that they have plotted on the lines
first you need to figure out what the points are, then insert it into the formula
the formula for this would be [tex]\frac{Y2- Y1}{X2-X1}[/tex]
Part 2:
its asking you to find the slope using the points that are written in each box

When solving an equation, which of the following is true
A. Use properties of equality to get the variable and constant terms on the same side of the equation
B. Always isolate the variable on the left side of the equation
C.Use properties of equality to get the variable on one side of the equation and constant terms on the other.
Answers
Answer:
C. Use properties of equality to get the variable on one side of the equation and constant terms on the other.
Step-by-step explanation:
In solving an equation, It is true that properties of equality should be used by putting the variable on one side and the constant on the other side.
Now let use an example to drive this;
Given:
2x - 9 = x + 8
This is an equation, and what we have on both sides should be equal.
Collect like terms;
2x - x = 8 + 9
x = 17
So the solution is 17.
This is the best way to solve an equation.
Solve in inequality: -2 (3x + 5) ≥ 10
Answers
Answer:
x ≤ -10/3
Step-by-step explanation:
Step 1: Write inequality
-2(3x + 5) ≥ 10
Step 2: Solve for x
Distribute -2: -6x - 10 ≥ 10Add 10 to both sides: -6x ≥ 20Divide both sides by -6: x ≤ 20/-6Simplify: x ≤ -10/3Here we see that any value less than or equal to -10/3 will work as a solution.

-6x > 20

x < -3.33 repeating

Boyle’s law states that when considering gases, volume varies inversely with pressure. If V represents the volume of the gas and P represents the pressure of the gas, what would the formula be that represents this relationship? If a balloon has a volume of 4 L of gas with a pressure of 5 atmospheres, what will the volume be when the pressure is 3 atmospheres?
The formula is V = kP, and when P = 3, V = 4/3
The formula is V = kP, and when P = 3, V = 5/3
The formula is k = VP , and when P = 3, V = 4.
The formula is k = VP, and when P = 3, V = 20/3
Answers
Answer:
D.
[tex]V = 20/3L[/tex]
Step-by-step explanation:
Given
[tex]P = 5atm; V = 4L[/tex]
Required
Determine V when P = 3atm
Boyles Law states that;
[tex]k = VP[/tex]
When : [tex]P = 5atm; V = 4L[/tex]
[tex]k = 5 * 4[/tex]
[tex]k = 20[/tex]
Using the same formula:
[tex]k = VP[/tex]
When [tex]P = 3atm[/tex]
We have:
[tex]20 = V * 3[/tex]
Solve for V
[tex]V = 20/3L[/tex]
Answer:
D.) The formula is k = VP, and when P = 3, V = 20/3

What is the equation of the line that passes through the point (-9. 6) and is
perpendicular to the line -5 + x = 3y
Answers
Answer:
The perpendicular equation is y = -3x -21
Step-by-step explanation:
Perpendicular lines have the exact opposite slope as the other equation and they never have the same y-intercept.
To find the perpendicular slope just look at the slope in the original equation and get the exact opposite.
First let's simplify the equation.
-5 + x = 3y (divide by 3 on both sides to get y by itself)
-5/3 + 1/3x = y or y = 1/3x + 5/3
The exact opposite of this slope would be -3.
Now plug in the point you were given so that we can find the y-intercept.
6 = -3(-9) + b (b = y-intercept)
6 = 27 + b (subtract 27 on both sides)
-21 = b
So the perpendicular equation looks like this.
y = -3x -21

A cable television station runs a marathon broadcasting 11 hours of program A, immediately followed by 11 hours of program B, immediatly followed by 11 hours of C. If the first episode of program A begins at 8pm. What time does the last episode of program C end?
Answers
Answer:
2 am
Step-by-step explanation:
We are told in the question that:
A cable television station runs a marathon broadcasting 11 hours of program A, immediately followed by 11 hours of program B, immediatly followed by 11 hours of C. If the first episode of program A begins at 8pm. What time does the last episode of program C end?
Program A
8pm + 11 hours = 6am
Program A ends by 6am
Program B
Starts by 6 am
6am + 11 hours = 4 pm
Program B ends by 4 pm
Program C
Starts by 4 pm
4 pm + 11 hours = 2am
Program C ends by 2 am
Answer:
[tex]End\ Time = 4am[/tex]
Step-by-step explanation:
Given
[tex]Start\ Time = 8pm[/tex]
[tex]A = 11\ hours[/tex]
[tex]B = 11\ hours[/tex]
[tex]C = 11\ hours[/tex]
Required
Determine when the last episode of C ends.
This is calculated as thus;
[tex]End\ Time = Start\ Time + A + B + C[/tex]
[tex]End\ Time = 8pm + 11\ hours + 11\ hours + 11\ hours[/tex]
[tex]End\ Time = 8pm + 33\ hours[/tex]
Split 33 hours into 24 hours + 9 hours
[tex]End\ Time = 8pm + 24\ hours + 9\ hours[/tex]
24 hours after a certain time equas the same time on a different day:
[tex]End\ Time = 8pm + 9\ hours[/tex]
9 hours after 8pm is 4am
Hence:
[tex]End\ Time = 4am[/tex]

Answers
Answer:
f(-2) = -5
f(0) = 5
f(1) = 10
Step-by-step explanation:
f(-2) = 5(-2) + 5 → -10 + 5 = -5
f(0) = 5(0) + 5 → 0 + 5 = 5
f(1) = 5(1) + 5 → 5 + 5 = 10
