3. Given a system of two equations in two variables, replacing one equation by the sum of that equation and a multiple of the other produces a system with the same solution. Show why this is true by solving the system of equations given. Justify the reason for each step. HINT: Use the addition property of equality and multiplication property of equality in your answers. (8 points: 1 point for each question)
5x + 2y = 7
3x – y = 2
To solve the system using elimination, first multiply the bottom equation by 2. Write the new system of equations. (1 point)
Why is this multiplication allowed? (1 point)
What variable will be eliminated when the equations are combined after
the multiplication? (1 point)
Next, add the equations together. Your answer should be a single equation with one variable. (1 point)
Why can you add the equations? (1 point)
Solve the equation for x. (1 point)
Substitute x back into one of the equations to solve for y. (1 point)
What is the solution to the system of equations? (1 point)
Answer:
Step-by-step explanation:
To solve the system using elimination, first multiply the bottom equation by 2. Write the new system of equations. (1 point)
5x + 2y = 7
6x –2y = 4
Why is this multiplication allowed? (1 point)
Because the entire equation was multiplied by the same number, the equation remains the same.
What variable will be eliminated when the equations are combined after the multiplication? (1 point)
The Y variable
Next, add the equations together. Your answer should be a single equation with one variable. (1 point)
11x = 11
Solve the equation for x. (1 point)
X = 1
What is the solution to the system of equations? (1 point)
X = 1 and Y = 1 so the answer is (1, 1)
(If you solve this again, but eliminate the X variable, you will still receive that answer 1, so Y = 1)

B 3(v + 5) = 2v + 15 + v

When solving: 1,175 ÷ 5, using partial quotients, how would you decide which power of 10, when multiplied by 5, should be subtracted first?
Answer:
1,165
Step-by-step explanation:
To solve 1,175 ÷ 5 by using partial quotient we should subtracted 10², when multiplied by 5.
What is mean by Subtraction?
Subtraction in mathematics means that is taking something away from a group or number of objects. When you subtract, what is left in the group becomes less.
Given that;
The expression is,
⇒ 1,175 ÷ 5
Now,
Solve the expression 1,175 ÷ 5 by using partial quotients as;
5 ) 1,175 (
- 500 100
------
675 135
-675
--------

The height of a free falling object is represented by the expression -16t2 + v02 + h0 where v o is the initial velocity of 80 feet per second. And h o is the initial height of 25 feet what is the height of the object at t = 2 seconds ( pls no fake answers )
Answer:
The height of the object after 3 seconds is 45 feets.
Step-by-step explanation:
The height of an object thrown into the air with an initial upward velocity of 63 feet per second is given as
Where, h(t) is height of the object in feet and t is the time in seconds.
We have to find the height of the object after 3 seconds. So, substitute t=3.
Therefore height of the object after 3 seconds is 45 feets.

Students on the softball team earned $295 from a car wash. How many team banners can they buy if each banner costs $8? Explain how you interpreted the remainder.
Answer:
37 banners (Or 36 since it would cause 1 dollar off.)
Step-by-step explanation:
The reason why the teams would be able to buy this much is because if we divide 8 and 295, to which it would give the number 36.

F(x) = 6 (1/8)^x is an example of
An exponential growth function
A logarithmic growth function
An exponential decay function
A logarithmic decay function
Answer:
Exponential decay. Your growth factor is 1/8, which is between 0 and 1. Thus, the value is decreasing exponentially.
If the growth factor is greater than 1, you have exponential growth. Logarithmic functions will always contain a logarithm, so you can quickly rule out those options.

How many 1/8 tps can go into 1/8 cup?
Answer:
6 tps
Step-by-step explanation:
3 tsp = 1 tablespoons
16 table spoons = 1 cup
therefore 48 teaspoons = 1 cup
therefore 1/8th cup =6 teaspoons
Answer:
(1/8) cup = 6 U. S. teaspoons
Step-by-step explanation:
Do a quick Internet search. Type '1 cup = teaspoons" into the address line as tho' you were doing a search. Result: 1 cup = 48 U. S. teaspoons.
We want to know the teaspoon equivalent of 1/8 cup. To get this, multiply both sides of the above equation by 1/8:
(1/8) cup = (1/8)(48 U. S. teaspoons), or (1/8) cup = 6 U. S. teaspoons.
