using the elimination method how do I find x and y for the following problem:
3x+5y=-1
x + 5y = 4
Answers
Answer:
x is equal to -3, and y is equal to eight fifths, or 1.6
Step-by-step explanation:
Solving by elimination means to add or subtract one of the equations from the other, eliminating one of their common terms.
Because both of the provided ones have the term 5y (and no other y terms), let's use subtraction:
3x + 5y = -1
- ( x + 5y = 5 )
2x + 0 = -6
Which we can solve pretty quick:
2x = -6
x = -3
We can now solve either of the original equations for y:
x + 5y = 5
-3 + 5y = 5
5y = 8
y = 8/5, or 1.6
To make sure we're correct, let's test our results in the other equation:
3x + 5y = -1
3 × -3 + 5 × 8/5 = -1
-9 + 8 = -1
-1 = -1
So we're good!

Find f(3)
Answers
f(3) = -394
HELP ASAP (20 POINTS)
The function f is modeled by the equation f(x) = 5x + 4 What is the range of the function when the domain is {-2,3,5}? A. {19,-6,29}
B.{-6,16,29}
C.{-6,19,29}
D.{14,16,24}
Answers
The range of the function will be;
⇒ { - 6, 19, 29 }
What is Domain?The set of all inputs of the function is called Domain of set.
Given that;
The function is,
⇒ f (x) = 5x + 4
And, The domain = {-2, 3, 5}
Now,
Since, The function is,
⇒ f (x) = 5x + 4
We know that;
The range of the function gives the value of f (x).
So, We get;
The function is,
⇒ f (x) = 5x + 4
Put x = - 2;
⇒ f (-2) = 5 × - 2 + 4
= -10 + 4
= - 6
Put x = 3;
⇒ f (3) = 5 × 3 + 4
= 15 + 4
= 19
Put x = 5;
⇒ f (5) = 5 × 5 + 4
= 25 + 4
= 29
Thus, The value of range = { - 6, 19, 29 }

Step-by-step explanation:
So the associative and commutative properties basically say That you can change the orders of the numbers and the answer won't change (for multiplication and addition).
Your answer would be D because they added the numbers with a decimal place together, it makes it easier to look at, and add in your head.

What should be the first step in adding these equations to eliminate y?
8x + 3y = 2
+ 4x - 6y= -7
O A. Multiply the top equation by 4.
O B. Multiply the bottom equation by 8.
C. Multiply the bottom equation by 2.
D. Multiply the top equation by 2.
Answers
D. Multiply the top equation by 2.
Answer:
D
Step-by-step explanation:
Given the 2 equations
8x + 3y = 2 → (1)
4x - 6y = - 7 → (2)
Multiplying the top equation (1) by 2 and adding to (2) will eliminate y
16x + 6y = 4 → (3)
Add (2) and (3) term by term to eliminate y
20x + 0 = - 3
20x = - 3 ( y has been eliminated )

What is the length of the hypotenuse?
C=
meters
Answers
Pythagorean Theorem: a^2 + b^2 = c^2
A and B are the sides given to us, because they're not the hypotenuse. Square each at add them.
That leaves you with 289. Square root it, because we want to find C without being squared.
The square root of 289 is 17, so the hypotenuse is 17 m in length

Answers
Correct question is;
Peter wants to make four necklaces that are the same way. He asked his friends to cut the string for the necklace 15 paper clips long. Would all the lengths be the same? Explain your think
Answer:
No, the lengths would not be the same. This is due to the fact the the paper clips could be in different sizes.
Step-by-step explanation:
We are told that he wants to make four necklaces that are the same way and that he told his friends to cut the string for the necklace 15 paper clips long.
Now, we are not told the sizes of the paper clips and we know that paper clips come in different sizes. Thus the paper clips in which the strings are cut could be in different sizes. Therefore, the lengths wouldn't be the same due to that.

We have to check each option one by one, It is sum of two perfect square, As we know sum of two perfect square can't be factored. It is prime equation.
Here we have two factor (4x+4) and (x+1). In both factor degree of x is 1. It is complete factor form. Here we have two factor 4x and x²-4. For second factor it is further factor. Because it is difference of square. Factor of x²-4 = (x+2)(x-2)
Complete Factor: 2x(x+2)(x-2)[/tex],
Here variable are not same. So, it can't be factor (false)
