Answer: A

Step-by-step explanation:

For the x-intercept, we know y=0. We can eliminate B and D.

We know either A or C is the correct answer. This line is linear so there should be only one x-intercept. We can solve this equation to see which is correct. Let's plug in A and C into the equation to see which is right.

A. Correct

7(-\frac{3}{7} )=2(0)-3

-3=-3

C. Incorrect

7(\frac{3}{2} )=2(0)-3

\frac{21}{2}\neq  -3

Answer:

(-3/7, 0)

Step-by-step explanation:

7x=2y-3

To find the x intercept, set y = 0 and solve for x

7x = 0-3

7x = -3

Divide each side by 7

7x/7 = -3/7

x = -3/7

The x intercept is

(-3/7, 0)

I need answer please​
zhenek [66]

Answer:

We know that lines <em>l</em><em> </em>and <em>m</em><em> </em>are parallel. The alternate interior angles rule states that the alternate interior angles formed by parallel lines are equal. So let's equate them.

2x + 22 = 4x

putting variables on one side,

22 = 4x - 2x

Thus 2x = 22

x becomes 22÷2

Therefore,<u> x = 11.</u>

*If you add two integers with different signs, how can you tell whether the sum will be positive, negative, or zero?
irina [24]

Answer:

Please see explanation

Step-by-step explanation:

When two integers are being added there can be three cases in the answer

  • <u>Positive</u>

The sum will be positive if both the integers are positive and in case of addition of one positive and negative integer, the sum will be positive if the integer with larger magnitude is positive

  • <u>Negative</u>

The sum will be negative if both integers are negative and in case of addition of one positive and negative integer, the sum will be negative if the integer with larger magnitude is negative

  • <u>Zero</u>

The sum will be zero if both the integers have same magnitude and different signs.
