Evaluate the expression -8x + 5 - 2x - 4 + 5x when x = 2 before and after simplifying.

Alex777 [14]

Answer:

Step-by-step explanation:

all we have to do is plug in 2 for x into the equation:

-8(2) + 5 -2(2) -4 + 5(2)

-16 + 5 -4 -4 + 10

-11 -8 + 10

-19 + 10

the answer is

-9

to simplify the equation we’ll combine like terms

-8x + 5 -2x -4 + 5x

-10x + 1 + 5x

-5x + 1

now we’ll plug in 2 for x

-5(2) + 1

-10 + 1

the answer is still

-9

Given: circle k(O), m∠P=95°, m∠J=110°, m∠LK=125°<br> Find: m∠PJ

IRINA_888 [86]

Answer:

The measure of the arc PJ is $75\°$

Step-by-step explanation:

step 1

Find the measure of angle L

we know that

In a inscribed quadrilateral opposite angles are supplementary

$m$

we have

$m$

substitute

$m$

step 2

Find the measure of arc KJ

we know that

The inscribed angle measures half that of the arc comprising

$m$

substitute the values

$95\°=\frac{1}{2}(125\°+arc\ KJ)$

$190\°=(125\°+arc\ KJ)$

$arc\ KJ=190\°-125\°=65\°$

step 3

Find the measure of arc PJ

we know that

The inscribed angle measures half that of the arc comprising

$m$

substitute the values

$70\°=\frac{1}{2}(65\°+arc\ PJ)$

$140\°=(65\°+arc\ PJ)$

$arc\ PJ=140\°-65\°=75\°$
