The Figure Shows Two Angles. What Is The Value Of X?

Answers

Answer 1

Answer:

x=70

Step-by-step explanation:

First subtract 30 from 180

180-30=150

Subtract 10 from 150

150-10=140

Divide 140 and 2

140÷2=70

Answer 2

Answer:

x=70

Step-by-step explanation:

angles on a straight line add to 180

so first you do 180-30 which equals to 150

this means that 2x+10=150

take away 10 from both sides and your left with

2x=140

since you are finding x

you divide both sides by 2

x=70

How many root(s) does the following equation have? Explain how you know for credit.
-6x2 - 6x + 7 = 7

Answers

Answer:

This equation has two roots.  We know this because of the format it is in.  Any expression in the form ax² + bx + c is a quadratic one, which describes a parabola and has two roots.

In this case, the roots are -1 and 0.

Step-by-step explanation:

Let's see if we can find those values:

-6x² - 6x + 7 = 7

-6x² - 6x = 0

x² + x  = 0

x(x + 1) = 0

x = -1, 0

We could also run through solving this by completing the square:

-6x² - 6x + 7 = 7

-6x² - 6x = 0

x² + x  = 0

x² + x + 0.25 = 0.25

(x + .5)² = 0.25

x + .5 = ±√0.25

x + .5 = ± 0.5

x = -0.5 ± 0.5

x  = -1, 0

Which symbol makes the statement true?-2x> or equal to 16 so x ? -8

Answers

Given:

The inequality is

[tex]-2x\geq 16[/tex]

To find:

The correct symbol for the inequality x __ -8.

Solution:

We have,

[tex]-2x\geq 16[/tex]

When we divide or multiply an inequality by a negative number, then we need to change the sign of inequality.

Divide the given inequality by -2.

[tex]\dfrac{-2x}{-2}\leq \dfrac{16}{-2}[/tex]

[tex]x\leq -8[/tex]

The correct symbol for the blank is ≤.

Therefore, the correct option is J.
