0 7

X values pair with y values

Plug in x to get a y

for example plug in 2 to get 7-4=3

y = 7 which you subtract from 2x which means 2 times x so you use all of those as the value of 2 to see what the answer would be after you multiply it by 2

What is the measure of EAB in circle F? 72° 92° 148° 200°

Arada [10]

We have been given a diagram. We are asked find the measure of arc EAB.

First of all, we will find the measure of arcs ED and CB using our given information.

We know that measure of an inscribed angle is half the measure of intercepted arc.

We can see that angle EBC is inscribed angle of arc EDC, so measure of arc EDC will be twice the measure of angle EBC.

$\widehat{EDC}=2\times m\angle EBC$

$\widehat{EDC}=2\times 80^{\circ}$

$\widehat{EDC}=160^{\circ}$

Similarly, we will find the measure of arc DCB.

$\widehat{DCB}=2\times m\angle DEB$

$\widehat{DCB}=2\times 70^{\circ}$

$\widehat{DCB}=140^{\circ}$

$\widehat{ED}=\widehat{EDC}-\wdiehat{DC}$

$\widehat{ED}=160^{\circ}-88^{\circ}$

$\widehat{ED}=72^{\circ}$

$\widehat{ED}+\widehat{DCB}+\widehat{EAB}=360^{\circ}$

$72^{\circ}+140^{\circ}+\widehat{EAB}=360^{\circ}$

$212^{\circ}+\widehat{EAB}=360^{\circ}$

$\widehat{EAB}=360^{\circ}-212^{\circ}$

$\widehat{EAB}=148^{\circ}$

Therefore, the measure of arc EAB is 148 degrees and option C is the correct choice.

Summer is approaching, so workers at the Lawrenceville Community Center are filling the pool. The volume of water in the pool x

Vanyuwa [196]

9514 1404 393

Answer:

The pool is being filled

Step-by-step explanation:

The function definition tells you ...

f(5) = the volume of water in the pool 5 minutes after they start

f(10) = the volume of water in the pool 10 minutes after they start

So, the inequality ...

f(5) < f(10)

means the volume of water in the pool 10 minutes after they start is greater than it is 5 minutes after they start. In short, they are filling the pool.

Which of these triangle pairs can be mapped to each other using a single reflection?

kondor19780726 [428]

Answer:

Second triangle pair

Step-by-step explanation:

In a reflection, the shape is flipped. In the first pair, the corresponding sides as shown by the lines, and the corresponding angle are already in the same position. In the second pair, Δ MLN can be reflected so that line LN match with EG and line LM matches with line EF. ∠L and ∠E will also be mapped to each other when one triangle is reflected.

A tree is 7 ft tall when it is planted and this type of tree grows two feet per year. How tall will the tree be in 6 years? How

s344n2d4d5 [400]

2x+7=?

X=6

2(6)+7=

12+7=19

In six years, the tree will be 19ft

2x+7=44

Minus seven on both sides

2x=37

Divide two from both sides

X=18.5

Thus, it will take 18 and a half years for the tree to reach 44ft
