Answer:

Step-by-step explanation:

y = -2x - 4

y = 3x + 3

Since both lines have different slopes, they're non-parallel.

Any pair of non-parallel lines meet an one point. So exactly one solution

y=-2x-4

y=3x+3

2x+y=-4

-3x+y=3

2x+y=-4

3x-y=-3

+---------

5x=-7 //5

x=-7/5

3*(-7/5)+y=3

y=-6/5

x=-7/5

y=-6/5

(x – 2)^2 + 20 = 0

seraphim [82]

Answer:

x = 2 ± 2 sqrt(5)i

Step-by-step explanation:

(x – 2)^2 + 20 = 0

Subtract 20 from each side

(x – 2)^2 + 20 -20=0 -20

(x – 2)^2 =- 20

Take the square root of each side

sqrt((x – 2)^2) =±sqrt(- 20)

x-2 = ±sqrt(- 20)

We know sqrt(ab) = sqrt(a) sqrt(b)

x-2 = ±sqrt(- 1) sqrt(20)

We know the sqrt (-1) = i

x-2 = ±i sqrt(4*5)

x-2 = ±i sqrt(4) sqrt(5)

Add 2 to each side

x-2+2 = 2 ±i sqrt(4) sqrt(5)

x = 2 ±i 2 sqrt(5)

x = 2 ± 2 sqrt(5)i

Olivia baked 16 mini-loaves of banana bread to be sliced for snacks at a craft fair. She will place an equal number of loaves in

lukranit [14]

Answer:

The number of whole loaves at each location = 5 loaves

Step-by-step explanation:

This problem is essentially testing your ability to use simple division within remainders, and the number of whole loaves is calculated as follows:

Numer of loaves of bread = 16

number of locations = 3

next, we will divide the number of loaves by the number of locations since Olivia placed an equal number of loaves in 3 different locations:

$= \frac{16}{3} = 5\frac{1}{3}$

This means that there will be 5 whole loaves and 1 loaf that will be divided equally into the three places.

Therefore, the number of whole loaves at each location = 5 loaves

<em>but remember that there will be a remainder of 1 loaf.</em>

Alexis loves to work out on the treadmill. On Monday, she ran 1.52 miles. On Tuesday she ran 0.75 miles. On Wednesday she ran 2.

poizon [28]

Answer:

1.08 Miles

How I Found The Answer:

2.65 + 1.52 + 0.75 = 4.92

6 - 4.92 = 1.08

I Said Alexis Wished To Have An Even Number So She Ran 1.08 Miles.
