Use the numbers 0 through 9 to complete each equation so the statement about it's solution is true

belka [17]

For the first equation, to get an equation that only has 1 solution your two missing numbers could be 3x and 6. This is because when you solve it, you get 7x + 2 = 3x + 6
- 3x
4x + 2 = 6
- 2
4x = 4
x = 1

For the second equation, your two numbers could be 7x and 4, because it means that x has to be different as 7 multiplied by one number and added to 2 cannot equal 7 multiplied by the same number but added to 4.

I hope this helps!

The equation of the line through (3 -4) with slope 2/3 is:<br> WILL GIVE BRAINLIST

LUCKY_DIMON [66]

Answer:

$y = \frac{2}{3}x - 6$ .

Step-by-step explanation:

(3 , -4) ; slope(m) = 2/3

y - y1 = m (x -x1)

$y - [-4] = \frac{2}{3}(x - 3)\\\\y + 4 = \frac{2}{3}x - 3*\frac{2}{3}\\\\y +4 = \frac{2}{3}x-2\\\\ y = \frac{2}{3}x - 2 - 4\\\\ y = \frac{2}{3}x - 6$

What are the coordinates of the image of point L(4, 2) after a reflection over the line y = –1?

andrey2020 [161]

Answer:

L'(4, -4)

Step-by-step explanation:

When you're given a midpoint, you can find the point equidistant on the other side of the midpoint by subtracting the relevant coordinate from <em>double that of the midpoint</em>.

Here, the line of reflection is the horizontal line y=-1, so you know only the y-coordinate will change. The reflected point will be ...

(x, y) ⇒ (x, -2-y)

so the point of interest is ...

L' = (4, -2-2) = (4, -4)
