Answer:
y = 0
Step-by-step explanation:
Plug in 28 for x. Solve for the equation:
x + 3y = 28
(28) + 3y = 28
Isolate the variable, y. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS. First, subtract 28 from both sides:
28 (-28) + 3y = 28 (-28)
3y = 0
Isolate the variable, y. Divide 3 from both sides:
(3y)/3 = (0)/3
y = 0
y = 0 is your answer.

If p(x)=2x^2-4x and q(x) = x-3, what is (p o q)(x)
Answer:
2x² - 16x + 30
Step-by-step explanation:
To evaluate (p ￮ q)(x)
Substitute x = q(x) into p(x)
2(x - 3)² - 4(x - 3)
= 2(x² - 6x + 9) - 4x + 12
= 2x² - 12x + 18 - 4x + 12
= 2x² - 16x + 30

3[–x + (2 x + 1)] = x – 1 solve for x
Hey there! :)
3[-x + (2x + 1)] = x - 1
Simplify the parenthesis!
3[-x + 2x + 1] =x - 1
Add like terms.
3[x + 1] = x - 1
Simplify!
3x + 3 = x - 1
Subtract 1x from both sides.
3x + 3 - 1x = x - 1 - 1x
Simplify.
2x + 3 = -1
Subtract 3 from both sides.
2x = -4
Divide both sides by 2.
2x ÷ 2 = -4 ÷ 2
Simplify.
x = -2

What is the solution of the equation 92x = 6? Round your answer to the nearest ten-thousandth.
Answer:
The solution of the equation 92x = 6 is x= 0.065
Step-by-step explanation:
We need to solve the equation 92x = 6 and find the value of x.
Given: 92x = 6
Divide both sides of the equation with 92
92x/92 = 6/92
x = 3/46
x = 0.065
So, the solution of the equation 92x = 6 is x= 0.065

Answer:
d = 6
Step-by-step explanation:
d = sqrt((x2 - x1)^2 + (y2 - y1)^2 )
Givens
x2 = -12
x1 = -6
y2 = 4
y1 = 4
Solution
d = sqrt (-12 - - 6)^2 + (4 - 4)^2 )
d = sqrt ( ( - 6)^2 + 0)
d = sqrt(36)
d = 6
Answer:
6
Step-by-step explanation:
Calculate the distance (d) using the distance formula
d = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = (- 6, 4) and (x₂, y₂ ) = (- 12, 4)

Find the output y, when input x is 6
Answer:
0
Step-by-step explanation:
Final answer:
To find the output y for an input x of 6, assuming a linear relationship based on a derivative example provided, we use the equation y = 3x + 6. Substituting x with 6 gives us y = 24.
Explanation:
The question requires us to find the output y when the input x is 6. The equation provided in the excerpts can be interpreted in many ways due to lack of clarity in the given information. However, a linear function example is given by dy/dx = 6+3x, where the derivative suggests an initial value of 6 increasing by 3 with each unit increase in x. If we assume a linear relationship y = mx + b, we can use the pattern in the derivative example and set the slope m as 3 and the y-intercept b as 6. This yields the equation y = 3x + 6. When x is 6, the output y is calculated as y = 3(6) + 6 = 18 + 6 = 24.
Remember, the equation provided in the tutorial only applies if we assume a linear relationship based on the derivative example mentioned. It is important to have the exact equation or context to provide the precise output y.
The cost of performance tickets and beverages for a family of four can be modeled using the equation 4x + 12 = 48, where x
represents the cost of a ticket. How much is one ticket?
$3.00
$4.00
$9.00
$15.00
Answer:
C) $9.00
Step-by-step explanation:
You're trying to find the value of x. 4x + 12 = 48 Subtract 12 from both sides to get:4x = 36 Then, divide each side by 4 to get:x = 9For this case we have that the cost of a ticket is given by the variable "x". We have the following equation:
[tex]4x + 12 = 48[/tex]
By clearing "x" we have:
We subtract 12 on both sides of the equation:
[tex]4x = 48-12\\4x = 36[/tex]
Dividing between 4 on both sides of the equation:
[tex]x = \frac {36} {4}\\x = 9[/tex]
Then, a ticket costs $ 9.00

OXY is the longest side.
Angle X is the largest angle.
Angle Z is greater than angle Y.
XZ is opposite the largest angle.
XZ is the shortest side.
Save and Exit
Answer: 2nd, 3rd, and 5th are true
Step-by-step explanation:
The first statement cannot be true, if n ≥ 5, which is given, then ZY must be greater than XY
The second statement must be true, as long as n ≥ 5, ZY will always be greater than XZ and XY, and therefore, the angle opposite to ZY will always be the greatest angle, so X is the largest angle
The third statement must be true for the same reasoning as the second statement. The side opposite to angle Z will always be greater than the side opposite of angle Y, meaning that angle Z will always be greater than angle Y (assuming n ≥ 5).
The fourth statement is false, we already proved that X is the largest angle and XZ is not opposite of angle X.
The fifth statement is true, XZ will always have the lowest value as long as n ≥ 5.
All the correct statements regarding the sides and angles of the triangle are,
⇒ Angle X is the largest angle.
⇒ Angle Z is greater than angle Y.
⇒ XZ is the shortest side.
What is mean by Triangle?A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.
Given that;
Triangle XYZ is shown,
where n ≥ 5
Now, We get;
For n = 5;
XY = n + 4 = 5 + 4 = 9
YZ = 2n = 2 x 5 = 10
ZX = n - 2 = 5 - 2 = 3
Hence, We get;
⇒ ZX < XY < YZ
And, ∠X > ∠Z > ∠Y
Thus, All the correct statements regarding the sides and angles of the triangle are,
⇒ Angle X is the largest angle.
⇒ Angle Z is greater than angle Y.
⇒ XZ is the shortest side.

6) A cereal box has the following dimensions:
height of 12 inches and width of 2 inches. If
the volume of the box is 192 cubic inches.
find the length of the box.
Hint: V = lwh
Answer:
8 inches
Step-by-step explanation:
The problem gives us a basic formula, the volume formula for a rectangular prism. All we have to do is use this formula, plug in all the values that are given, and solve for the unknown value.
[tex]V = lwh[/tex]
[tex]192 = l(12)(2)[/tex]
[tex]192 = 24l[/tex]
From here, all we need to do is divide 24 from both sides of the equation, since what you do to one side of the equation you must do to the other!
[tex]8 = l[/tex]
The length of the box will thus be 8 inches.
it is going to be 8 inches Hope it helps !!!!!
The sum of two numbers is 90. The larger number is 14 more than 3 times the smaller number. Find the numbers
The larger number is 71 and the smaller number is 19.
Two equations can be derived from the question:
x + y = 90 equation 1
x = 14 + 3y equation 2
The larger number would be represented with x and the smaller number would be represented with y.
Substitute for x in equation 1
14 + 3y + y = 90
Add similar terms
14 + 4y = 90
Make y the subject of the formula
4y = 90 - 14
4y = 76
y = 76 / 4 = 19
Substitute for y in equation 1
x + 19 = 90
x = 90 - 19
x = 71

The sum of numbers is the addition of the numbers.
The numbers are 19 and 71
Let the two numbers be x and y, where y is greater than x.
So, we have:

The sum of the numbers is:
[tex]\mathbf{x +y = 90}[/tex]
Substitute [tex]\mathbf{y = 3x + 14}[/tex]
[tex]\mathbf{x +3x + 14 = 90}[/tex]
[tex]\mathbf{4x + 14 = 90}[/tex]
Subtract 14 from both sides
[tex]\mathbf{4x = 76}[/tex]
Divide both sides by 4
[tex]\mathbf{x = 19}[/tex]
Substitute [tex]\mathbf{x = 19}[/tex] in [tex]\mathbf{y = 3x + 14}[/tex]
[tex]\mathbf{y = 3(19) + 14}[/tex]
[tex]\mathbf{y = 71}[/tex]

Simplify 8x + 9x completely.
Answer:
[tex]17x[/tex]
Step-by-step explanation:
[tex]8x + 9x = 17x[/tex]
To simplify the expression 8x + 9x, you combine the like terms by adding the coefficients. The result is 17x.
Explanation:The process involved in simplifying an equation like this is known as combining like terms. In this example, the terms are 8x and 9x. Because they both contain the same variable, x, you can combine them.
To perform this operation, you add the coefficients (the numbers in front of the variable). In this case, the coefficients are 8 and 9. So, 8x + 9x simplifies to 17x.
Therefore, the simplified form of the equation 8x + 9x is 17x.

Which expression is equivalent to..? Assume
Answer:
The equivalent ratio of (3m⁻²n)⁻³/6mn⁻² = m⁵/2n
Step-by-step explanation:
Points to remember
Identities
xᵃ * xᵇ = x⁽ᵃ ⁺ ᵇ⁾
xᵃ/xᵇ = x⁽ᵃ ⁻ ᵇ⁾
(xᵃ)ᵇ = xᵃᵇ
x⁻ᵃ = 1/xᵃ
To find the equivalent ratio of (3m⁻²n)⁻³/6mn⁻²
By using identities,
(3m⁻²n)⁻³ = 3m⁶n⁻³
(3m⁻²n)⁻³/6mn⁻² = 3m⁶n⁻³/6mn⁻²
= 3m⁽⁶⁻¹⁾n⁽⁻³ ⁻ ⁻²⁾/6
= m⁵n⁻¹/2
= m⁵/2n
Therefore the equivalent ratio of (3m⁻²n)⁻³/6mn⁻² = m⁵/2n
