Answer:
A. (-3, 2)
Step-by-step explanation:
First step is to revert the equation into y = mx + b form.
-4x + 2y = 16 turns into y = 2x+8
Now just plug in the points given to see which one matches.
(-3,2) the x is -3 so if you plug that into the equation it should get you 2 which is the y.
2 = 2(-3) + 8
2 = 2
So we know that (-3, 2) is the solution.
If you plug in the other points they wont come out equal. For example, (4,-1)
-1 = 2(4) + 8
-1 = 16
So (4,-1) cant be a solution. The same thing applies for (2, -3).

A rectangle is 9 centimeters long and 5 centimeters wide. What is the diameter?
Answer:
A rectangle doesn't has a diameter
________________________________
But if you are asking about perimeter.
Step-by-step explanation:
Perimeter = 2(l + b)
l = 9cm
b = 5cm
Perimeter = 2(l + b)
= 2(9 + 5)
= 18 + 10
= 28cm
Solve for y.
14-y= b
The value of y in the expression 14 - y = b is y = 14 + b.
What is a numerical expression?A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.
Given, An expression 14 - y = b, Now solving for 'y' is the same as finding the value of y so we'll separate y on the LHS and all the other terms on RHS.
Therefore,
14 - y = b.
- y = b - 14.
- ( - y) = - (b - 14).
y = 14 + b.

-x + 1 = x + 21
solve for x
I need this asap
Answer:
x = -10
Step-by-step explanation:
-x + 1 = x + 21
(given)
__________
-x + 1 = x + 21
+x +x
(addition property of equality)
(add the x term on both sides to cancel out -x)
__________
1 = 2x + 21
-21 -21
(subtraction property of equality)
(subtract by 21 on both sides to get rid of the constant term on the x side)
________
-20 = 2x
÷2 ÷2
(division property of equality)
(divide to get rid of the coefficient of 2 in the x term)
_______
-10 = x
(symmetric property of equality)
(switch both sides so that x is on the left)
_______
x = -10
________________________________
Proof by substitution:
x = -10 because
x = -10 → -x + 1 = x + 21 → -(x) + 1 = (x) + 21 → -(-10) + 1 = (-10) + 21 → 10 + 1 = 21 - 10 →
11 = 11
Answer:
x=10
Step-by-step explanation:
Put both of the x on one side, and the numbers on the other side (this breaks down the equation).
This is make it easier for you to add/substract/divide/multiply.

Answer: 5/8
Step-by-step explanation:
When multiplying two fractions together, always try to cross-cancel if possible as your first step.
In this problem the 3 and 6 reduce to 1 and 2.
Next we simply multiply across the numerators and multiply across the denominators and we have our answer which is 5/8
The area of a square is (9x2 − 12x + 4) square units. Determine the length of each side of the square by factoring the area expression completely
Step-by-step explanation:
9x2 − 12x + 4 = 18 - 12x + 4 = 22 - 12x = 2(11 - 6x)
length of 1 side = ± sqrt 2(11-6x) (rej neg value)

The graphs of functions f and g are shown.
Function g is defined as . What is the value of c?
The value of c is __.
Answer:
The value of c is 3
Step-by-step explanation:
Here, we want to get the value of c
From the question, we can select a single x-point
when x = 16
f(x) = 2
g(x) = -1
Thus;
g(16) = f(16) - c
-1 = 2 - c
c = 2 + 1
c = 3

Megan's bank account is charged $9.95 per month for an online newspaper subscription how can you represent a change in her account balance after three months of charges
Answer:
T = C - (9.95 * 3)
Step-by-step explanation:
The account balance total can be calculated with the following equation where the variable T represents the final balance while the variable C represents her current balance before the three months...
T = C - (9.95 * 3)
The monthly charge is multiplied by the three months that Megan will be charged and then discounted from her current balance in order to give the new Total Balance after paying the subscription for the three months.
You newton, and Descartes volunteer this summer. You have 2 times as many volunteer min as newton Descartes have 5040 volunteer min altogether how many min do you volunteer
Complete question is;
You, newton, and Descartes volunteer this summer. You have 2 times as many volunteer min as newton and Descartes. You all have 5040 volunteer min altogether. how many min do you volunteer?
Answer:
2520 volunteer minutes
Step-by-step explanation:
You have 2 times as many volunteer minutes as Newton and Descartes.
Now, if Newton and Descartes each have x volunteer minutes, it means you have 2x volunteer minutes.
Since the total volunteer minutes of the 3 of you is 5040,then we have;
2x + x + x = 5040
4x = 5040
x = 5040/4
x = 1260
Since you have 2x volunteer minutes, then you have: 2 × 1260 = 2520 volunteer minutes
