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

Answer:
[tex](x+3)(x-3)[/tex]
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.
If you wish to check this answer you can peform the "FOIL" method (first, outside, inside, last) in order to solve the equation which would result in:

what is 3x+3=6x-57 i need ur help
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.
What is the multiplicative inverse of 1 5/42
Answers
Answer:
I'm not to sure
Answer:
inverse of 5/42 = -42/5 = -8 2/5 = -8.4
inverse of 15/42 is flipped -42/5 = -2.8
The decimal steps are;
if 5/42 then show -1/1 = 5/42 = 42/5 = 8 2/5
= 8.4
if 15/42 then -1/1 ÷15/42 = -14/5
= -2.8
Step-by-step explanation:
if the question was 15/42 then we divide by -1 /15/42 = -42 / 15
so we can divide all by -1 or -1/1
The calculation steps are ;
-1/1÷ 15/42
= -1/1×42/15
= -1 × 42 / 1 × 15
= -42/15
The decimal steps are;
if 5/42 then show -1/1 = 5/42 = 42/5 = 8 2/5
= -8.4
if 15/42 then -1/1 ÷15/42 =–14/5
= –2.8
