Answers
Answer:
x=20
Step-by-step explanation:
Answer:
x=20
Step-by-step explanation: Sorry the explination is long i got it of a website i use for my math tests.
Simplifying
3x + 3 = 6x + -57
Reorder the terms:
3 + 3x = 6x + -57
Reorder the terms:
3 + 3x = -57 + 6x
Solving
3 + 3x = -57 + 6x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-6x' to each side of the equation.
3 + 3x + -6x = -57 + 6x + -6x
Combine like terms: 3x + -6x = -3x
3 + -3x = -57 + 6x + -6x
Combine like terms: 6x + -6x = 0
3 + -3x = -57 + 0
3 + -3x = -57
Add '-3' to each side of the equation.
3 + -3 + -3x = -57 + -3
Combine like terms: 3 + -3 = 0
0 + -3x = -57 + -3
-3x = -57 + -3
Combine like terms: -57 + -3 = -60
-3x = -60
Divide each side by '-3'.
x = 20
Simplifying
x = 20

Please help me solve this problem ASAP
Answers
Here’s Why:
We first see that -6x is subtracted from both sides to cancel the +6x out on the left side and combine it with the other like term on the right side, which is 16x. That step is correct.
The next step, we see that -40 is subtracted from 400. THIS IS THE ERROR. To cancel out the 400, then -400 should be taken from it and not -40! This is because the constant of 400 on the left side must be canceled out by -400 from it to make it 0, so that it can combine like terms with the constant on the left side of 150.
So, the error is that -40 was taken instead of -400.

Find the x and y intercepts for the following equation. 2x– 7y=-14
A. X int. = -7 Yint. = 2
B. X int. = 7 Yint. = -2
C. Xint. = 2 Yint. = -7
D. X int. = -2 Y int. = 7
Answers
Answer:
C: Xint = 2, Yint. = -7
Step-by-step explanation:
Given the equation, 2x - 7y = -14:
The y-intercept is the point on the graph where it crosses the y-axis, and has coordinates (0, b). It is also the value of y when x = 0. To solve for the y-intercept, set x = 0:
2x - 7y = -14
2(0) - 7y = -14
0 - 7y = -14
-7y = -14
Divide both sides by -7 to solve for y:
-7y/-7 = -14/-7
y = 2
Therefore, the y-intercept = 2.
Next, the x-intercept is the point on the graph where it crosses the x-axis, and has coordinates, (a, 0). To find the x-intercept, set y = 0 and substitute into the given equation:
2x - 7y = -14
2x - 7(0) = -14
2x - 0 = -14
2x = -14
Divide both sides by 2 to solve for x:
2x/2 = -14/2
x = -7
x-intercept = -7.
Therefore, the correct answer is C: Xint = 2, Yint. = -7

what function models the height of the periscope lens at time t? If the periscope reaches its maximum Heught after ascending for 22 seconds, what is the maximum height in feet? ( 24 inches above the surface and ascends at 6 inches per sec.)
Answers
Answer:
Step-by-step explanation:
First we are going to find the function which models the height of the
periscope lens at time t.
Let the 2 be height of the periscope.
The height of the periscope at the beginning is 24 inches. It ascends at 6
inches per second. The expression which describes how much it has raised,
at the moment, is 6t.
The function is sum of beginning height and how much it has raised, 2 = 24 + 6t.
To find maximum height of the periscope, we need to evaluate function
for + = 22.
2 = 24 + 6(22)
= 24 + 132
156
Substitute 22 for t.
Multiply.
Maximum height in inches is 156.
We know that 1 foot is 12 inches.
So the function that describes converting feet to inch is y :
= 12x. Where y
represents number of inches and a number of feet.
U = 12.2
156
12x
12
-n=
156
12
2 = 13
Substitute 156 for y.
Divide both sides by 12.
Maximum height in feet is 13.
The height function modeled by the periscope is an illustration of a linear function.
The height function modeled by the periscope is [tex]\mathbf{h(t) = 24+ 6t}[/tex]The maximum height is 156 inchesThe given parameters are:
[tex]\mathbf{Start = 24\ inches}[/tex]
[tex]\mathbf{Rate = 6\ inches/second}[/tex]
The function model of the height is calculated using:
[tex]\mathbf{h(t) = Start + Rate \times t}[/tex]
Where: t represents the time in seconds
So, we have:
[tex]\mathbf{h(t) = 24+ 6\times t}[/tex]
This gives
[tex]\mathbf{h(t) = 24+ 6t}[/tex]
After 22 seconds, the height of the periscope would be
[tex]\mathbf{h(22) = 24+ 6 \times 22}[/tex]
Multiply
[tex]\mathbf{h(22) = 24+ 132}[/tex]
Add
[tex]\mathbf{h(22) = 156}[/tex]
Hence, the maximum height is 156 inches

Step-by-step explanation:
This equation is called a "difference in perfect squares".
The resulting answer should be: [tex](x + y)(x-y)[/tex] where the y variable is the square root of the given number. In this instance, the integer 9
So knowing that the square root of 9 is 3 we can plug in 3 for both of the y spots which results in our answer.
