I'm not 100 percent sure but I don't think it has a direct variant.

Which sets of ordered pairs are from linear functions? Select the TWO answers that apply. Group of answer choices {(0,1),(1,2),(

Karo-lina-s [1.5K]

Answer:

{(0,1),(1,2),(2,3),(3,4)}
{(0,4),(1,6),(3,10),(5,14)}

Step-by-step explanation:

When x-differences are the same, y-differences will be the same for a linear function. When they are not the same, they will be proportional for a linear function.

{(0,1),(1,2),(2,3),(3,4)} - x-differences are all the same; y-differences are all 1 (linear, y=x+1)

{(0,0),(1,1),(2,4),(3,9)} - x-differences are all the same; y-differences increase (this is a quadratic function: y=x^2)

{(1,1),(2,8),(3,27),(4,64)} - x-differences are all the same; y-differences increase (this is a cubic function: y=x^3)

{(0,4),(1,6),(3,10),(5,14)} - x-differences are 1, 2, 2; y-differences are 2, 4, 4, so are proportional to (double) the x-differences (linear; y=2x+4)

Matt gets paid at home for doing extra chores. Last week, he did 6 loads of laundry and 1

emmasim [6.3K]

Matt earns $4 and $3 for 1 load of laundry and 1 load of dishes respectively

<u>Solution:</u>

Given, Matt gets paid at home for doing extra chores.

We have to find How much does Matt earn for completing each type of chore?

Let the amount for 1 load of laundry be m and amount for 1 load of dish be n.

Now, last week, he did 6 loads of laundry and 1 load of dishes, and his parents paid him $27.

Then, 6 $\times$ amount for 1 load of laundry + 1 $\times$ amount for 1 load of dish = 27

$\rightarrow 6 \mathrm{m}+\mathrm{n}=27 \rightarrow(1)$

The week before, he finished 1 load of laundry and 9 loads of dishes, earning a total of $31

Then, 1 $\times$ amount for 1 load of laundry + 9 $\times$ amount for 1 load of laundry = 31 ⇒m + 9n = 31 ⇒ (2)

Now let us solve equations (1) and (2)

0 – 53n = - 159

-53n = -159

53n = 159

n = 3

Now, substitute n value in (1) ⇒ 6m + 3 = 27 ⇒ 6m = 24 ⇒ m = 4

Hence, matt earns $4 and $3 for 1 load of laundry and 1 load of dishes respectively.

If arc VY = 132° and ∠YUV = 41°, what is the measure of arc XV?

Tom [10]

Answer:

50

Step-by-step explanation:

Use this equation

$\frac{b - a}{2} = angle \: yuv$

where b is arc VY, A is arc XV.

Substitute the equation in

$\frac{132 - a}{2} = 41$

$132 - a = 82$

$- a = - 50$

$a = 50$

so our arc measure is 50
