Answer: 13) 90 degrees, 14) 137 degrees, 15) 93 degrees 16) 96 degrees

Step-by-step explanation:

Answer:

13) ?=90°

14) ?=180°-48° (int angles, u//v)

=132°

15) ?=93° (alt angles, u//v)

16) ?=96° (alt angles, u//v)

Answer:

D.

Step-by-step explanation:

Your graph of f(x)= [tex]x^2[/tex] is the parent function. What you need to know for this graph what the stretch or compression is and what the flip is. When you flip somehting over the x-axis, which is g(x), your [tex]x^2[/tex] is negative. Also, since your graph gets skinnier, the number before the x would be a whole number, with no fractions. The only answer that fulfills this is answer choice D.

Answer:28 / 4 = -7.

Step-by-step explanation:

28 / 4 = -7.28 / 4 = -7.28 / 4 = -7.

Answer:

6x²-2x+2

Step-by-step explanation:

For g(f(x)), we have to first do f(x), and then substitute it into the "x" in g(x)

So, f(x) = 3x²-x+1

We need to substitute the "x" in g(x) with this entire thing

So, g(x) = 2x

When we substitute f(x) into it, it instead becomes 2(3x²-x+1)

Next, we have to expand the brackets, and doing so gives us the following:

6x²-2x+2

So that becomes our final answer!

Let me know if it makes sense! :)

Answer:

line 1

Step-by-step explanation:

perpendicular is the opposite so therefore line 1 is the answer

From the given figure, line AB perpendicular to line 1.

We need to check which line is perpendicular to AB.

In elementary geometry, two geometric objects are perpendicular if they intersect at a right angle. The condition of perpendicularity may be represented graphically using the perpendicular symbol, ⟂. It can be defined between two lines, between a line and a plane, and between two planes.

From the given figure we can see that line AB perpendicular to line 1.

The line AB perpendicular to line 1, intersect each other and made an angles 90°.

Therefore, from the given figure, line AB perpendicular to line 1.

Answer:

-4 1/2

-4.5

-4.5 / 4 = -1.125

Answer: -1.13, or -1 1/8

Step-by-step explanation:

Answer:

1) x + 4 = 11

Subtract 4 on both sides, to get x = 7 .

2) x + 3 = 24

Subtract 3 on both sides, to get x = 21 .

3) 4x = 12

Divide 4 on both sides, to get x = 3 .

4) 5x + 3 = 33

First subtract 3 on both sides to get

5x = 30, now divide 5 on both sides, to

get x = 6 .

5) 8x + 5 = 3x + 20

First subtract 5 from 20 in order to

move it, now you have 8x = 3x + 15 .

Next subtract 3x from 8x in order to

move it, now you have 5x = 15 . Lastly

divide 5 on both sides, to get x = 3 .

1) 1/2 x = 4

Multiply both sides by 2, to get 1x = 8,

or x = 8 .

2) 4/3 x = 4

Multiply both sides by 3, to get 4x = 12 .

Next divide 4 on both sides to get

x = 3 .

3) 2x + (-4) = 8

Add 4 on both sides, to get 2x = 12 .

Next divide 2 on both sides to get

x = 6 .

4) 1/3 x + 1/2 x = 20

First multiply the denominators to get a

common denominator of 6 and then

add 3 and 2, to get the numerator. Now

you have 5/6 x = 20 . Next multiply 6

on both sides to get 5x = 120 . Lastly

divide 5 on both sides to get x = 24 .

5) 1/3 x = 1/5 x + 10

First multiply the denominator to get a

common denominator of 15 and then

subtract 3 from 5 to get the numerator.

Now you have 2/15 x = 10 . Next

multiply 15 on both sides to get

2x = 150. Lastly divide 2 on both sides

to get x = 75 .

Answer:

(1 , 2) and  (3 , 6)

Step-by-step explanation:

the point P : (x , y) -> (x , 2x)    ... ordinate of P point is twice its abscissa, y = 2x

√10 = √(x-4)² + (2x-3)²

5x² - 20x + 25 = 10

x² - 4x + 3 = 0

(x-1)(x-3) = 0

x = 1    or    x = 3

Descending order:

14560g

13.6kg

13.25kg

12000g

a.) [tex]\frac{18}{5}[/tex]

b.) [tex]\frac{25}{2}[/tex]

Step-by-step explanation:

To find the difference between kg or g, either divide kg by 100 to convert to g, or multiply g by 1000 to convert to kg.

If we were to put everything into g:

14560g

13600g

13250g

12000g

See how they are still in the correct order?

If we were to put everything into kg:

14.56kg

13.6kg

13.25kg

12kg

Still in descending order!

___________________

Now to find out how to put the decimals into fractions:

Multiply by 10 (since there is only 1 digit behind the decimal, for every digit behind the decimal you multiply by another factor of 10, so if you have 2.55 you multiply by 100)

Following this we get:

36

125

Now divide by the same factor (10), we can't change the value of the number, just the way they look!

[tex]\frac{36}{100}[/tex]

[tex]\frac{125}{10}[/tex]

All that's left is it reduce!

[tex]\frac{18}{5}[/tex]

[tex]\frac{25}{2}[/tex]

And as you can see, we are back to the number I had put in the solution!
