Answer:

x= 1.5

y= 4.125

Step-by-step explanation:

Step one:

given the two equations

-2x - 8y = -30-------1\\\\2x + 8y = 36--------2

Step two:

let us subtract the equations

-2x - 8y = -30-------1\\\\ -(2x + 8y = 36)--------2\\\\0x-16y=-66

-16y=-66\\\\16y=66

divide both sides by 16

y=66/16\\\\y=4.125

put y= 4.125 in equation 2

2x + 8(4.125)= 36\\\\2x+33=36\\\\2x=36-33\\\\2x=3\\\\x= 3/2\\\\x= 1.5

Graph: y=|x - 4| + 2
kramer

Answer:

See attached graph.

Step-by-step explanation:

We can graph this with relative ease on the calculator or computer (see attachment) but let's make sure we understand it theoretically and algebraically!

y=|x - 4| + 2

First of all, this is an absolute value function, so it'll look like a v where every input equals its positive output (2, 2) (-3,3) etc. You can't get a negative number with a graph of y=|x| unless you translate it.

Next, there's a -4 inside the abs val. According to the formula y = |x - h| + k, where h is the horizontal shift, this means we need to shift the vertex right 4.

There's a +2 outside the abs val. K is the vertical shift, so we need to shift the vertex up 2.

O.6 as a mixed number
ella [17]

Answer:

3/5

Step-by-step explanation:

To make 0.6 as a fraction (you can't make it a mixed number because there is no number to the left of the point) place a 1 under it to make it a fraction:

0.6/1

Since you can't have a decimal on a fraction, multiply by 10;

0.6/1 × 10/10 =6/10

Simply your answer (6/10) to get 3/5
