Answer:

y = -4x - 16 or y +4x + 16 = 0

Step-by-step explanation:

Gradient (m) = -4

Equation of a line given gradient and one point=

y - <em>y </em>= m(x - <em>x)</em><em> </em>where (<em>x </em>, <em>y </em>) are the coordinates of the point.

Substituting...

y -(-4) = -4(x -(-3))

y + 4 = -4(x + 3)

y + 4 = -4x - 12

y = -4x - 12 - 4

y = -4x - 16 or y +4x + 16 = 0

In the addition problem at the right, each letter stands for a digit and different letters stand for different digits. What digi
AVprozaik [17]

In the addition problem attached, the letters H = 2, E = 3, A = 9. See the explanation below.

<h3>What is the explanation for the above?</h3>

In the problem, A depicts a single digit i.e; A < 9.

=> 4H<10

=>H<3

i.e; H should be 1 or 2.

In units column, 4E should have H in units place in the result. i.e; 1 or 2

As 4E is always an even number, H cannot be 1.

=> H = 2

If H = 2, E can be 3 or 8 for 4E to end in 2.

If E = 8, the result will be a three-digit number => E = 3

So if H = 2 and E = 3

A = 9

Therefore, the letters

H = 2,

E = 3, and

A = 9.

Which equations represent the line that is parallel to 3x − 4y = 7 and passes through the point (−4, −2)? Check all that apply.
Kryger [21]
<span>3x − 4y = 7
4y = 3x - 7
  y = 3/4 x - 7/4 slope = 3/4

</span><span>parallel lines, slope is the same so slope = 3/4
</span><span>passes through the point (−4, −2)
</span>equation
y + 2 = 3/4 (x + 4)
4y + 8 = 3x + 12
3x - 4y = -4
