Multiply the equation 2x+7y=-1 by -2

add to othe equaiton
4x-3y=-19
<u>-4x-14y=2 +</u>
0x-17y=-17

-17y=-17
divide both sides by -17
y=1

sub back
2x+7y=-1
2x+7(1)=-1
2x+7=-1
minus 7 from both sides
2x=-8
divide both sides by 2
x=-4

x=-4
y=1

The output with the y being -4
aivan3 [116]

For this case we have a function of the form y = f (x), where f (x) = - 4x. We must find the values of "and" according to the following function:y = -4x

So:

f (-6) = - 4 (-6) = 24\\f (-2) = - 4 (-2) = 8\\f (3) = - 4 (3) = - 12

Thus, the values are:

24,8, -12

Answer:

24,8, -12

What is greater 3 x 1/10 plus 4 x 1/100 plus 8x 1/1000 greater than one and two tenths
Elena L [17]
So, first let's change these numbers into decimal form:
3*0.1 + 4*0.01 + 8*0.001 ? 1.2
Multiply:
0.3 + 0.04 + 0.008 ? 1.2
0.348 < 1.2
One and two tenths is larger.
Hopefully this is what you're asking, as this question is unclear
