Elimination using addition and subtraction. <br> -4x+4y=-20<br> -2x+4y=-2

goldfiish [28.3K]

I would subtract the 2nd from the first one

so -4x - -2x = -2x

4y - 4y = 0

-20 - -2 = -18

-2x = -18

now I would divide that by -2 to get the value for x

so no we have x = 9

now you just have to substitute that into one of the equations and simplify to get y

-2 X 9 + 4y = -2

-18 + 4y = -2

4y =16

y = 4

Bogdan [553]

Answer:

160% of 35 is 56.

$\frac{56}{y} :\frac{160}{100}$

y · 160 = 56 · 100

160y = 5600

160y ÷ 160 = 5600 ÷ 160

The graph of y=|x|y=∣x∣y, equals, vertical bar, x, vertical bar is shifted down by 999 units.

frosja888 [35]

Answer:

$y = |x| -9$

Step-by-step explanation:

The base function is given as

$y = |x|$

This graph opens up and has its vertex at the origin.

When we shift the graph of this function down by 9 units, its vertex is now at (0,-9)

The equation of this new graph is

$y = |x| -9$
