For this linear equation, give the number by which you would multiply the terms in each equation in order to eliminate one of the variables. Then solve this system:
5x+2y=-1; 3x+7y=11
This would be a big help if you also include the process to help me understand the answer!
Answer:
Step-by-step explanation:
The solution to this system of linear equations 3x – 2y = 14 and 5x + y = 32 is (x, y) is (6, 2).
Answer:
Step-by-step explanation:
If we choose to eliminate x, multiply the first equation by -3: -15x - 6y = 3
and multiply the second by 5: -15x - 35y = 55
Note that this allows us to eliminate x. We get:
-6y = 3
-35y = 55
which sum up to -41y = 58. Thus, y = -58/4.

Amy began with $25 in her bank account and spent $5 each day. Is this function linear or nonlinear? Explain your reasoning.
Answer: nonlinear
Step-by-step explanation:
Think of it.
She’s spending $5 each time. That would be going down.
So that would be nonlinear
Answer:
linear
Step-by-step explanation:
Because it is a straight line and has a pattern unlike a non linear which wouldnt be following a pattern
Emily has fixed monthly expenses that are taken directly out of her bank account.
Emily wants to know how much money she must deposit in her account each month to cover these expenses.
How can Emily use an additive inverse to find this amount?
Answer:
Emily must deposit each month.
Step-by-step explanation:
As you know that Additive inverse of any number
A = - A, For example additive inverse of 2 is - 2
or additive inverse of (-2) is 2.
Now, According to the question given
Emily has fixed monthly expenses that are taken directly out of her bank account.
As she wants to know, how much money she must deposit in her account each month to cover these expenses.
So, Expenses are Additive inverse of Deposit or Deposit are additive inverse of Expenses.
Out of the given Options Option D which is, Emily can add (-48) + (-12) + (-44) to find her total expenses. The additive inverse of this number is the amount Emily must deposit each month. is correct

Evaluate the expression for the given values.
8x+2yz, where x=12, y = 4, and z = 2
Answer:
112
Step-by-step explanation:
8x+2yz is our starting equation
8(12)+2(4)(2) I then substitute the variables for their numbers
96+2(4)(2) I then multiply 8x12, which equals 96.
96+8(2) I now multiply 2x4, which is 8.
96+16 I finally multiply 8x2 which is 16
112 Lastly I then add 96+16 which equals 112.

1/4 times the sum of a number and −3.2 is 1.8
What is the number?
Enter your answer as a simplified mixed number.
The mixed number for the given case can be obtained as 10²/₅.
How to write a linear equation?A linear equation for the given case can be written by assuming any variable as the unknown quantity. Then, as per the given data the required operations are done and it is equated to some value.
Suppose the number be x.
Then, the following equation can be written for information given as,
1/4(x - 3.2) = 1.8
It can be solved as,
x - 3.2 = 1.8 × 4
⇒ x = 7.2 + 3.2 = 10.4
It can be written in mixed form as below,
10.4 = 10 + 4/10
⇒ 10 + 2/5 = 10²/₅
Hence, the required number is 10²/₅.

pls help me with this problem i will give brainly.
Answer:
We are given that:
variables x and y vary directly, this means that:
y = kx where k is the constant of proportionality
Now, we are also given that:
y = 45 at x = 40.
We will use these values and substitute in the above relation to get k as follows:
y = kx
45 = 40k
k = 45/40 = 9/8 = 1.125
Based on the above calculations, the equation that relates x and y is:
y = 1.125x

what is bigger 5.62 or 5.5
Answer:
5.62
Step-by-step explanation:
5.62 is bigger than 5.5
5.62 is bigger by 0.12
You can prove this by subtracting 5.5 from 5.62
If you were to subtract 5.62 from 5.5 you'd end up with a negative number, so obviously 5.62 is bigger
Use the properties of exponents to complete the equivalent expression.

Answer:
10/12 simplified 5/6
Answer:
A) [tex]\frac{5}{6}[/tex]
Step-by-step explanation:
So solve, change the sign into multiplication and use the reciprocal of the second number.
To find the reciprocal, flip the numerator and the denominator.
The reciprocal of 4/5 is 5/4.
So you have [tex]\frac{2}{3}[/tex]×[tex]\frac{5}{4}[/tex]
Multiply like a normal expression.
You get 10/12, which can be simplified to [tex]\frac{5}{6}[/tex]
