Answer 1
So for the top one the mistake is they didn’t multiply by a negative(2 is supposed to be negative)so your answer would be -6 and just put down the the other steps and change that.

Answers

Answer:

9³

Step-by-step explanation:

We need to find the value of [tex]\dfrac{9^5}{9^2}[/tex].

We know that,

[tex]\dfrac{x^a}{x^b}=x^{a-b}[/tex]

Here, a = 5 and b = 2.

So,

[tex]\dfrac{9^5}{9^2}=9^{5-2}\\\\=9^3[/tex]

So, the answer to the given expression is 9³.

1) A straight line is perpendicular to y=2x+5 and passes through (0,3).
What is the equation of the line??
2) A straight line is perpendicular to y=0.5x+3 and passes through (3,5).
What is the equation of the line??
3) A straight line is perpendicular to y=4-5x and passes through (20,5).
What is the equation of the line??

Answers

Answer:

See explanations below

Step-by-step explanation:

We are going to be using the point slope form of equation of a line for all the question, This is expressed as;

y-y0 = m(x-x0)

1) For a straight line is perpendicular to y=2x+5 and passes through (0,3).

Slope of the line m = 2

Slope of the line perpendicular M = -1/m

M = -1/2

Substituting M = -1/2 and the point (0,3) into the equation

y-y0 = m(x-x0)

y - 3 = -1/2(x-0)

y-3 = -x/2

2(y-3) = -x

2y-6 = -x

-x-2y = -6

x+2y = 6

The required equation is x+2y = 6

2) For a straight line is perpendicular to y=0.5x+3 and passes through (3,5).

Slope of the line m = 0.5

Slope of the line perpendicular M = -1/m

M = -1/0.5

M  = -2

Substituting M = -2 and the point (3,5) into the equation

y-y0 = m(x-x0)

y - 5 = -2(x-3)

y-5 = -2x+6

y+2x = 6 + 5

y+2x = 11

The required equation is y+2x = 11

3) A straight line is perpendicular to y=4-5x and passes through (20,5).

Slope of the line m = -5

Slope of the line perpendicular M = -1/m

M = -1/-5

M  = 1/5

Substituting M = -2 and the point (20,5) into the equation

y-y0 = m(x-x0)

y - 5 = 1/5(x-20)

5(y-5) = x-20

5y-25 = x-20

5y-x = -20+25

5y-x = 5

The required equation is 5y-x = 5

Yes, that is true.

find the measure of angle 8
​

Answers

Answer: 18

Step-by-step explanation:

First we need to solve for x to find the measure of the adjacent angle.

-6x+64 = 8x + 162

subtract 162 to leave x by itself

-6x- 98 = 8x

add 6x to both sides

-98 = 14x

now divide by 14

x = -7

Now solve one of the given equations to find the measure of the adjacent angle.

8(-7)+162

-56 + 162 = 106

Meaning the measure of angle 8 is 18

because they'll add up to 180(The measure of the line)

Answer:

measure of angle 8 is 16 6/7

Step-by-step explanation:

-6x+64=8x+62 because there is a transversal.

2=14x

x=2/14

so, now you have to find 8x+162. 163 1/7 degrees. (Plug in variables)

measure of the angle we just found + measure of angle 8 is 180 degrees.

(straight line definition) so 180-163 1/7= 16 6/7

measure of angle 8 is 16 6/7

Rosa loves to run. She set a goal to run greater than 490 miles this year. To date, she has run 145 miles. If she begins to run 15 miles per week, how long will it take Rosa to reach her goal?
Write an inequality, using x as the variable, that represents this situation.

Answers

Answer:

Step-by-step explanation:

145+15x>490. subtract 145 from both sides

15x>345, divide both sides by 15

x>23

So she will need to run for more than 23 weeks to reach her goal.
