{4z=8}<br> {3x-2z=11}<br> {x-4y+z=11}

tino4ka555 [31]

Step-by-step explanation:

4z = 8

z = 8/4

z = 2

3x - 2z = 11

3x - 2.2 = 11

3x - 4 = 11

3x = 11 + 4

3x = 15

x = 15/3

x = 5

x - 4y + z = 11

5 - 4y + 2 = 11

-4y = 11 - 5 - 2

-4y = 4

y = 4/-4

y = -1

Solution → {x,y,z} = {5,-1,2}

1) Andrea rents a bike for a day. The rental charges can be determined by

iris [78.8K]

Answer:

$0.5

Step-by-step explanation:

We have been given an equation $R=\$0.5d$ , where R is rental charges and d is number of days Andrea rents the bike. We are asked to find the unit rate.

We know that unit rate represents the ratio between two different quantities. Unit rate represents how many units of one quantity are equal to one unit of another quantity.

Let us divide both sides of given equation by d:

$\frac{R}{d}=\frac{\$0.5d}{r}\\\\\frac{R}{d}=\$0.5$

Therefore, the unit rate for our given problem would be $0.5, which represents rental charges per day.

Given the functions k(x) = 2x2 − 8 and p(x) = x − 4, find (k ∘ p)(x).

sweet-ann [11.9K]

$(k_ {0} p) (x) = 2x^2 -16x + 24$

<em><u>Solution:</u></em>

<em><u>Given functions are:</u></em>

$k(x) = 2x^2 - 8\\\\p(x) = x-4$

To Find: $(k_ {0} p) (x)$

By definition of compound functions,

$(k_ {0} p) (x) = k (p (x))$

Substitute p(x) value in x place in k(x)

$(k_ {0} p) (x) = 2(x-4)^2-8\\\\Expand\\\\(k_ {0} p) (x) =2(x^2 -8x +16) - 8\\\\(k_ {0} p) (x) = 2x^2 -16x + 32-8\\\\Simplify\\\\(k_ {0} p) (x) = 2x^2 -16x + 24$

Thus the required is found

Writing a mixed number and an improper fraction for a shaded...<br> Each circle counts as one whole

Lostsunrise [7]

Answer:

Mixed number = 2 $\frac{1}{4}$

Improper fraction = $\frac{9}{4}$

Step-by-step explanation:

These are the answers because:

1) The mixed number is 2 $\frac{1}{4}$ because there are two whole circles that are filled in, and the third circle is $\frac{1}{4}$ shaded in. Therefore, the mixed number is 2 $\frac{1}{4}$

2) The improper fraction is $\frac{9}{4}$ because there 2 whole circles that are filled in which is $\frac{8}{4}$ , and then $\frac{8}{4}$ + $\frac{1}{4}$ is $\frac{9}{4}$

Hope this helps!
