A refrigerator costs $429 to buy and its label says that estimated energy costs are $43 per year. Another brand costs $399, but its energy costs are $48 per year. If x is the years of ownership and y is the total dollars spent, write the ordered pair (x,y) that shows at what point the owner would have spent the same amount of money on either brand.

Use the Distributive Property to simplify the expression.
3(x+10)
Answer:
[tex]3x + 30[/tex]
3 times x +3 times 10
Hi, let me help you out!
- - - - - - - - - - - - - - - - - - - - - - - - - - - - -
In order to simplify this expression, we will use the Distributive Property:
—> a(b+c)=ab+ac
Simplify:
3(x+10)
Multiply 3 times x and 10:
3x+30
Hence, we conclude that the answer is: 3x+30.
I hope it helps you! Have an awesome day.

Find A, B so that y = A sin(2) + B cos(2) is a solution to the differential equation
4y'' +y' + 5y = 2 cos(x).
A=
BE
Submit Question
If y = A sin(x) + B cos(x), then
y' = A cos(x) - B sin(x)
y'' = -A sin(x) - B cos(x)
Substitute these into the ODE:
4y'' + y' + 5y = 2 cos(x)
4 (-A sin(x) - B cos(x)) + (A cos(x) - B sin(x)) + 5(A sin(x) + B cos(x)) = 2 cos(x)
(-4A - B + 5A) sin(x) + (-4B + A + 5B) cos(x) = 2 cos(x)
(A - B) sin(x) + (A + B) cos(x) = 2 cos(x)
Then
A - B = 0
A + B = 2
Adding these equation gives
(A - B) + (A + B) = 0 + 2
2A = 2
A = 1 → B = 1

Answer:
C: 2x - 7 = - 11
Step-by-step explanation:
If you insert -2 into the place of "x", you will have 2(-2) - 7.
2(-2) = -4, and -4 - 7 = -11.

What is the product of 1/4x-1/2 and 5x^(2) - 2x + 6? Write your answer in standard form. Show your work. Please this is due by tomorrow :c
Solution:
(4x2 - 2x) - (-5x2 - 8x)
= 4x2 - 2x + 5x2 + 8x.
= 4x2 + 5x2 - 2x + 8x.
= 9x2 + 6x.
= 3x(3x + 2).
Answer: 3x(3x + 2)
Solution:
(4x2 - 2x) - (-5x2 - 8x)
= 4x2 - 2x + 5x2 + 8x.
= 4x2 + 5x2 - 2x + 8x.
= 9x2 + 6x.
= 3x(3x + 2).
Answer: 3x(3x + 2)
Solution:
(4x2 - 2x) - (-5x2 - 8x)
= 4x2 - 2x + 5x2 + 8x.
= 4x2 + 5x2 - 2x + 8x.
= 9x2 + 6x.
= 3x(3x + 2).
Answer: 3x(3x + 2)

Solve the equation for all real solutions in simplest form.
3z^2+17z+16=0
Answer:
[tex]x=\frac{-17+\sqrt{97}}{6}[/tex], [tex]x=\frac{-17-\sqrt{97}}{6}[/tex]
Step-by-step explanation:
Use the quadratic formula to solve for all real solutions.
Quadratic formula: [tex]x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]
Plug in and solve:
[tex]x=\frac{-17\pm\sqrt{17^2-4(3)(16)}}{2(3)}\\\\x=\frac{-17\pm\sqrt{289-4(3)(16)}}{2(3)}\\\\x=\frac{-17\pm\sqrt{289-12(16)}}{2(3)}\\\\x=\frac{-17\pm\sqrt{289-192}}{2(3)}\\\\x=\frac{-17\pm\sqrt{97}}{6}\\[/tex]
Since that's the farthest we can simplify to, your answers would be the positive and negative versions of the expression:
[tex]x=\frac{-17+\sqrt{97}}{6}[/tex]
and
[tex]x=\frac{-17-\sqrt{97}}{6}[/tex]
The perimeter of a rectangle is 36 feet. The length is 2 less than 3 times the width. What is the length? What is the width?
(Please I will mark BRAINLIEST, not lie)Use this equation to solve for the missing variable:
y = 8x + 12
If x = -6, y = _____
If y = 13, x = _____
Answer:
If x = -6, y = -36
If y = 13, x = [tex]\frac{1}{8}[/tex]
Step-by-step explanation:
There is one equation and are asked to find x and y if there is a certain value to substitute either x or y.
Let's start with x, we know that x = -6. Meaning that we need to subtitute x for -6. Do as followed :
y = 8(-6) + 12
y = -48 + 12
y = -36
Now do y, we know that y is 13. Meaning that we need to substitute y for 13. Do as followed :
8x + 12 = 13
We need to isolate x alone, so do as followed :
Subtract 12 from both sides to get 8x alone :
8x = 1
Divide 8 from both sides to get x alone :
x = 1/8
