To solve this system of equations, we have to cancel out a variable:
12x-4y+28=0
16y-110=48x
Reorder:
12x-4y=-28
-48x+16y=110
Multiply first equation by 4:
4(12x-4y=-28)

3x2 + 7x - 6; x = 5
WILL GIVE BRAINLIEST WITH EXPLANATION
Answer:
[tex]3x^{2}[/tex] +x -6 ; x = 3
Step-by-step explanation:
PART 1: The Polynomial
1. Set up the Equation: (x+3)(3x-2) - 6x
You want to find the area of the larger of the 2 rectangles that way you can subtract the area of the smaller one to get the shaded area (if that makes sense). You multiply length by width to get the area so you will multiply (x+3) by (3x - 2). The same applies to the smaller of the two rectangles, so that will be 6x.
2.FOIL: [tex]3x^{2}[/tex] - 2x + 9x -6 - 6x
You are going to want to foil (x+3) and (3x-2). If you are unfamiliar with the FOIL method I would recommend watching a Khan Academy video about it.
3. Simplify: [tex]3x^{2}[/tex] +x -6
Add and subtract like terms. This will be your polynomial.
PART 2: The Value of x
1. Set up the Equation: [tex]3x^{2}[/tex] +x -6 = 24
You will set the polynomial to equal 24 the polynomial and number both equal the size of the shaded area
2. Subtract: [tex]3x^{2}[/tex] +x -30 = 0
Subtract 24 from both sides.
3. Factor: (3x + 10)(x - 3) = 0
4. Set each group to equal zero.
a. 3x + 10 = 0
3x = -10
x = -10/3
----------------
b. x - 3 = 0
x = 3
5. Check both the answers in [tex]3x^{2}[/tex] +x -6 = 24 to see if your answers are correct. The answer would be x = 3.
Polynomial representing the area of the shaded region will be (3x² - x - 6) square units and the value of 'x' is 3.
Area of a rectangle:Area of a rectangle is given by the expression,Area of a rectangle = Length × Width
Given in the picture,
Larger rectangle with measures,Length = (x + 3) units
Width = (3x - 2) units
Small rectangle with measures,Length = x units
Width = 6 units
Area of the shaded region = Area of the larger rectangle - Area of the smaller rectangle.
Area of the larger rectangle = (3x - 2) × (x + 3) square units
Area of the smaller rectangle = 6x square units
Area of the shaded region = (3x - 2)(x + 3) - 6x
= 3x(x + 3) - 2(x + 3) - 6x
= 3x² + 9x - 2x - 6 - 6x
= (3x² + x - 6) square units
If the area of the shaded region is 24 square units.
3x² + x - 6 = 24 [Substitute the values]
3x² + x - 30 = 0
3x² + 10x - 9x - 30 = 0 [Factor the equation]
x(3x + 10) + 3(3x + 10) = 0
(x - 3)(3x + 10) = 0
[tex]x=3,-\frac{10}{3}[/tex]
Therefore, polynomial representing the area of the shaded region will be (3x² - x - 6) square units and the value of x is 3.

Find the volume of the cylinder in terms of pi.
Answer:
The volume of the cylinder would be 226.19in however if you need it in terms of pi it would be V = 72 π in3
Step-by-step explanation:
V=πr2h=π·62·2≈226.19467, hope I was able to help you
And that is basically what you have to do
Answer:
72π inches^3
Step-by-step explanation:
The volume of a cylinder can be found using:
v=πr^2h
We know that the radius is 6 inches, and the height is 2 inches. So, we can substitute 6 in for r, and 2 in for h.
v= π 6^2 *2
Evaluate the exponent
v= π 36*2
Multiply 36 and 2
v= π72
So, the volume in terms of pi is:
72π inches^3

Simplify each side of the equation.
6-4 = k-3k
Answer:
k = -1
Step-by-step explanation: 6-4 = k-3k
subtract: 2 = -2k
divide both sides by -2: k = -1
simplifying is easy! we simply add or subtract like terms on each side.
6-4=2
1-3=-2 and then add k which is the variable so -2k
The equation would be 2=-2k and then we can divide both sides by -2 to isolate the variable to get -1=k

6% of it is 27
I need help. Someone please give me a explanation of how to do this.
Answer:
You take 6% of a number and the resulting number is 27.
To do this you need to change the percent into a fraction.
6% = 6/100
This is the number you need to multiply to the number you need to find, A.
6/100 A = 27
Solve for x
6 A = 27x100
A= 2700/6
A = 450
Check your answer:
6/100 (A) = 27
6/100 (450) = 27
(6x450) /100 = 27
2700 / 100 = 27
27 = 27

If you have a cubic polynomial of the form y = ax^3 + bx^2 + cx + d and lets say it passes through the points (2,28), (-1, -5), (4, 220), and (-2, -20) what would the coefficients a, b, c, and d equal? So confused, I'd greatly appreciate help! Thank you!
Answer:
a = 3
b = 2
c = 0
d = -4
Step-by-step explanation:
Form 4 equations and solve simultaneously
28 = a(2)³ + b(2)² + c(2) + d
28 = 8a + 4b + 2c + d (1)
-5 = -a + b - c + d (2)
220 = 64a + 16b + 4c + d (3)
-20 = -8a + 4b - 2c + d (4)
(1) + (4)
28 = 8a + 4b + 2c + d
-20 = -8a + 4b - 2c + d
8 = 8b + 2d
d = 4 - 4b
Equation (2)
c = -a + b + d + 5
c = -a + b + 4 - 4b+ 5
c = -a - 3b + 9
28 = 8a + 4b + 2c + d (1)
28 = 8a + 4b + 2(-a - 3b + 9) + 4 - 4b
28 = 6a - 6b + 22
6a - 6b = 6
a - b = 1
a = b + 1
220 = 64a + 16b + 4c + d (3)
220 = 64(b + 1) + 16b + 4(-b - 1 - 3b + 9) + 4 - 4b
220 = 60b + 100
60b = 120
b = 2
a = 2 + 1
a = 3
c = -3 - 3(2) + 9
c = 0
d = 4 - 4(2)
d = -4
Step-by-step explanation:
Step 1: Solve using the first point
(2, 28)
[tex]28 = a(2)^3 + b(2)^2 + c(2) + d[/tex]
[tex]28 = 8a + 4b + 2c + d[/tex]
Step 2: Solve using the second point
(-1, -5)
[tex]-5 = a(-1)^3 + b(-1)^2 + c(-1) + d[/tex]
[tex]-5 = -a + b - c + d[/tex]
Step 3: Solve using the third point
(4, 220)
[tex]220 = a(4)^3 + b(4)^2 + c(4) + d[/tex]
[tex]220 = 64a + 16b + 4c + d[/tex]
Step 4: Solve using the fourth point
(-2, -20)
[tex]-20 = a(-2)^3 + b(-2)^2 + c(-2) + d[/tex]
[tex]-20 = -8a + 4b - 2c + d[/tex]
Step 5: Combine the first and fourth equations
[tex]28 - 20 = 8a - 8a + 4b + 4b + 2c - 2c + d + d[/tex]
[tex]8 = 8b + 2d[/tex]
[tex]8 - 8b = 8b - 8b + 2d[/tex]
[tex](8 -8b)/2 = 2d/2[/tex]
[tex]4 - 4b = d[/tex]
Step 6: Solve for c in the second equation
[tex]-5 + 5 = -a + b - c + d + 5[/tex]
[tex]0 + c = -a + b - c + c + d + 5[/tex]
[tex]c = -a + b + d + 5[/tex]
Step 7: Substitute d with the stuff we got in step 5
[tex]c = -a + b + (4 - 4b) + 5[/tex]
[tex]c = -a + b + 4 - 4b + 5[/tex]
[tex]c = -a - 3b + 9[/tex]
Step 8: Substitute d and c into the first equation
[tex]28 = 8a + 4b + 2(-a - 3b + 9) + (4 - 4b)[/tex]
[tex]28 = 8a + 4b - 2a - 6b + 18 + 4 - 4b[/tex]
[tex]28 - 22 = 6a - 6b + 22 - 22[/tex]
[tex]6 / 6 = (6a - 6b) / 6[/tex]
[tex]1 + b = a - b + b[/tex]
[tex]1 + b = a[/tex]
Step 9: Substitute a, b, and c into the third equation
[tex]220 = 64(1 + b) + 16b + 4(-(1 + b) - 3b + 9) + (4 - 4b)[/tex]
[tex]220 = 64 + 64b + 16b + 4(-1 - b - 3b + 9) + 4 - 4b[/tex]
[tex]220 - 100 = 60b + 100 - 100[/tex]
[tex]120 / 60 = 60b / 60[/tex]
[tex]2 = b[/tex]
Step 10: Find a using b = 2
[tex]a = b + 1[/tex]
[tex]a = (2) + 1[/tex]
[tex]a = 3[/tex]
Step 11: Find c using a = 3 and b = 2
[tex]c = -a - 3b + 9[/tex]
[tex]c = -(3) - 3(2) + 9[/tex]
[tex]c = -3 - 6 + 9[/tex]
[tex]c = 0[/tex]
Step 12: Find d using b = 2
[tex]d = 4 - 4b[/tex]
[tex]d = 4 - 4(2)[/tex]
[tex]d = 4 - 8[/tex]
[tex]d = -4[/tex]
Answer: [tex]a = 3, b = 2, c = 0,d = -4[/tex]

Using multiplication, the equation has the solution is -7/2.
What is multiplication?
The multiplication is "the process of multiplying one number is to multiply to its certain number of times".
According to the question,
[tex]\frac{8}{x} + 3 = \frac{1}{x} +1[/tex]
[tex]\frac{(8+3x)}{x} = \frac{1+x}{x}[/tex]
8 + 3x = 1 + x [By cancel 'x' on both denominator]
8 - 1 = x - 3x
7 = -2x
x = - [tex]\frac{7}{2}[/tex]
Hence, using multiplication the equation has the solution is -7/2.
