Which equations represent the line that is parallel to 3x − 4y = 7 and passes through the point (−4, −2)? Select two options. y
andriy [413]

Answer:

Step-by-step explanation:

We want a line parallel to 3x − 4y = 7.  Any such line will have an equation of the same form but a different constant.

If the new line is to pass through the point (-4, -2), replace x with -4 and y with -2.  We obtain:

3(-4) − 4(-2) = -12 + 8 = -4.  Thus, the desired new equation is 3x − 4y = -4.

This could also be written as 3x − 4y + 4 = 0.  We could also solve this for y, obtaining:

3x + 4 = 4y, or  y = (3/4)x + 1.

9514 1404 393

Answer:

  arc AC = 63°

Step-by-step explanation:

Arc BC is twice the measure of inscribed angle BAC, so is ...

  arc AC = 2×89° = 178°

The remaining arc of the circle is the difference between 360° and the sum of the other two.

  arc AC = 360° -119° -178°

  arc AC = 63°

11Alexandr11 [23.1K]

Answer: 0.03 and 0.4

Step-by-step explanation:

3.0 would turn into 3.

3 divided by 100 is 0.03.

20 divided by 50 is 0.4

So, I think that it would be either 0.03 or 0.4
