What does x equal in y=|x| when y=-3

1 answer:

4 0

Replace all the variables that we know the value for.

-3 = |x|

Make to equations from this one.

-3 = x and -3 = -(x)

Solve the first one.

-3 = x
x = -3 <-- Switch it around

-3 = -(x)
-(x) = -3 <-- Switch it around
x = 3 <-- Divide both sides by -1

So, there are two possible answers, -3 and 3.

Consider this linear function y=1/2x+1 plot all ordered pairs for the values in the domain D:{-8,-4,0,2,6}

devlian [24]

Answer:

Following are the calculated points to the given question:

Step-by-step explanation:

$When\ x=-8\\\\y=\frac{1}{2}(-8)+1=-3\\\\$

so,

$Point \ A(-8,-3)$

$When\ x=-4\\\\y=\frac{1}{2}(-4)+1=-1\\\\$

so,

$Point \ B(-4,-1)$

$When\ x=0\\\\y=\frac{1}{2}(0)+1=1\\\\$

so,

$Point \ C(0,1)$

$When\ x=2\\\\y=\frac{1}{2}(2)+1=2\\\\$

so,

$Point \ D(2,2)$

$When\ x=6\\\\y=\frac{1}{2}(6)+1=4\\\\$

so,

$Point \ E(6,4)$

Mickey used these calculations to find how much he would spend on 7 cartons of eggs, if 12 cartons of eggs cost $22.20. Describe

timofeeve [1]

Mickey incorrectly calculated the unit price:
$\frac{12}{22.20} = 0.54$

The correct operation is:
$\frac{22.20}{12} = 1.85$

Each carton costs 1.85, so 7 cartons cost
$1.85 \times 7 = 12.95$
