Answers

Answer 1

Answer:

b=70 degrees

Step-by-step explanation:

a= 8x+6. b= 4x+38

a=b alternate exterior

combine like terms

8x+6=4x+38

Subtract 4x from both sides and 6

4x=32

Divide by 4

x=8

Plug in= 8 for B equation

b= 4(8)+38

b=70 degrees

Answer 2

Answer:

x = 8

m∠B = 70°

Step-by-step explanation:

The alternate exterior angles theorem states that m∠A and m∠B are the same. So,

8x + 6 = 4x + 38

Subtract 6 from both sides.

8x = 4x + 32

Subtract 4x from both sides.

4x = 32

Divide both sides by 4.

x = 8

Now to find the measure of m∠B, substitute x = 32 into 4x + 38.

8 * 4 + 38 =

32+ 38 = 70

m∠B = 70°

Just in case, let's double check our answer. Because m∠A is equal to m∠B, m∠A should be equal to 70.

70 = 8x + 6

70 = 8 * 8 + 6

70 = 64 + 6

70 = 70

Thus, x = 8 and m∠B = 70° is true.

I hope this helps! Feel free to ask any questions!

128= 4^2x times 2^x
What is x?

Answers

Answer:

x=7/5

Step-by-step explanation:

We can write it in exponential form

128= 2^2*2x * 2^x

2^4x+x=5x

2^5x=128

2^5x=2^7

5x=7

x=7/5

The value of x in the equation given is

[tex] \frac{7}{5} [/tex]

To solve :

[tex]128 = {4}^{2x} \times {2}^{x} [/tex]

Change all values to have the same root :

[tex] {2}^{7} = {2}^{2(2x)} \times {2}^{x} [/tex]

[tex] {2}^{7} = {2}^{4x} \times {2}^{x} [/tex]

[tex] {2}^{7} = {2}^{(4x + x)} [/tex]

[tex] {2}^{7} = {2}^{5x} [/tex]

The roots cancel out

[tex] 7 = 5x[/tex]

Divide both sides by 5

[tex]x = \frac{7}{5} [/tex]

Therefore, the value of

[tex]x = \frac{7}{5} [/tex]

Y+3= -5(x-1) write the equation in slope intercept form

Answers

Answer: The equation in slope-intercept form: [tex]y=-5x+2[/tex]

Step-by-step explanation:

The given equation of a line : [tex]y+3= -5(x-1)[/tex]

The equation of a line in slope -intercept form: y=mx+c, where m= slope , c=y-intercept.

We first use distributive property(a(b+c)=ab+ac) to simplify the given equation, we get

[tex]y+3=-5x+5[/tex]

Subtract 3 from both sides, we get

[tex]y=-5x-2[/tex]

Hence, the equation in slope-intercept form: [tex]y=-5x+2[/tex]

What is a coordinate system?

When determining the location of points or other geometrical elements on a manifold, such as Euclidean space, a coordinate system in geometry uses one or more numbers or coordinates.

The value of the coordinate x and the value of the coordinate y are both negative in the fourth quadrant's coordinate system.

As a result, it is true to say that both the x- and y-coordinates are negative. The correct response is B.

61 degrees

Answer:

Step-by-step explanation:

First set up the equation

130 + x + 30 + x + 22 = 180  (triangle angles always add up to 180)

then start to solve to find x

130 +2x + 30 + 22 = 180

182 + 2x = 180

-182          -182

2x = -2

/2     /2

x = -1

Then just plug it back into the equation
