can someone please help me:/!!! i’m a sophomore in hs, this is integrated math 2 chapter 2 test!

Answer:

Step-by-step explanation:

To find the inverse of the function you need to swap x and y

g(x)=y so therefore if you switch x and y, you get

x= 2y+ 10/4

Next, you need to get all of the values on the y side over to the x side. To do this you need to subtract 10/4 from the y side of the equation.

x-10/4=2y+10/4-10/4

The end product of this should be... (This is not your answer)

x-10/4=2y

Now you need to get rid of the 2 on the y side. To do this you need to divide both sides of the equation by 2

2/x-10/4=2y/2

So your answer is...

x-10/4 over 2 = y

OR

2/x + 5/4 = y

Answer:

Step-by-step explanation:

[tex]6x + \frac{1}{4} (4x + 8) > 12[/tex]

Expand the terms in the bracket

That's

[tex]6x + x + 2 > 12 \\ 7x + 2 > 12[/tex]

Subtract 2 from both sides of the inequality

That's

[tex]7x + 2 - 2 > 12 - 2 \\ 7x > 10[/tex]

Divide both sides by 7

That's

[tex] \frac{7x}{7} > \frac{10}{7} [/tex]

We have the final answer as

[tex]x > \frac{10}{7} [/tex]

Answer:

1:3

Step-by-step explanation:

To find the probability of selecting a certain type of item from a collection, simply divide the number of items of that type by the total number of items.

There are 3 + 2 + 1  = 6 marbles in total. There are 2 yellow marbles, so the probability of choosing a yellow marble on the first draw is 2/6. This can be further simplified to 1:3.

Answer:

i would say 2:4

Step-by-step explanation:

think about them as basketball teams

The yellow team has two players

the mix team has 4 players

so the game is 2 players on 4 players

Answer:

-225 feet

Step-by-step explanation:

The submarine started at -40 feet and wend down 185 feet which means the submarine is now at -225 feet.

Work:

-40 + (-185)

-40-185

-225

Final Answer: -225 feet

without an explanation your answer is (B) She lined up the front numbers instead of the decimal places.

if you need an explanation here:

________________________________________

For a problem with a decimal in the numbers, you ALWAYS have to line them up or your answer will be incorrect.

She should have put: 13.47

                                 +  1.56

                                    15.03

therefore, 15.03 would have been her correct answer. :-)

Answer:

[tex]\frac{3}{6}=\frac{7}{14}=\frac{29}{58}[/tex]

Step-by-step explanation:

By hit and trial method,

Given series of fractions will be,

[tex]\frac{3}{6}=\frac{7}{14}=\frac{29}{58}[/tex]

Since, [tex]\frac{3}{6}=\frac{3\times 1}{3\times 2}[/tex]

             [tex]=\frac{1}{2}[/tex]

[tex]\frac{7}{14}=\frac{7\times 1}{7\times 2}[/tex]

    [tex]=\frac{1}{2}[/tex]

[tex]\frac{29}{58}=\frac{29\times 1}{29\times 2}[/tex]

    [tex]=\frac{1}{2}[/tex]

Therefore, [tex]\frac{1}{2}=\frac{1}{2}=\frac{1}{2}[/tex] is the reduced form of the fractions.

[tex]\frac{3}{6}=\frac{7}{14}=\frac{29}{58}[/tex] will be the answer.

Step-by-step explanation:

To find the coordinate of the midpoint of segment QB, first, find the distance from Q to B.

QB = |4 - 8| = |-4| = 4

The coordinate of the midpoint of QB would be at ½ the distance of QB (½*4 = 2).

Therefore, coordinate of the midpoint of QB = the coordinate of Q + 2 = 4 + 2 = 6

OR

Coordinate of B - 2 = 8 - 2 = 6

Coordinate of the midpoint of QB = 6

Coordinate of W = -8

Coordinate of A = 0

distance from W to A (WA) = |-8 - 0| = |-8| = 8

The coordinate of the midpoint of WA would be at ½ the distance of WA = ½*8 = 4.

Therefore, coordinate of the midpoint of WA = the coordinate of W + 4 = -8 + 4 = -4

Or

Coordinate of A - 4 = 0 - 4 = -4

Coordinate of the midpoint of WA = -4

Now, let's find the midpoint between the two new coordinates we have found, which are -4 and 4

Distance of the segment formed by coordinate -4 and 4 = |-4 - 4| = |-8| = 8

Midpoint = ½*8 = 4

Coordinate of the midpoint = -4 + 4 = 0

Or

4 - 4 = 0

Step-by-step explanation:

Answer:

Step-by-step explanation:

Let the angles be x and y

If the two angles are complementary then their sum is 90 i.e x+y = 90

x = 90-y

If the two angles are supplementary, then their sum is 180 i.e x+y = 180

x = 180-y

If two times the complement of an angle is 23 less than the supplementary of the angle, this is written as;

2(90-y) = (180-y)-23

180-2y = 157-y

-2y+y = 157-180

-y = -23

y = 23

Hence the angle is 23°

Step-by-step explanation:

Kerry will earn $244.50 in total.

It is a method where we find the value of a single unit from the value of multiple units and the value of multiple units from the value of a single unit.

Steps to Use Unitary Method

First, let us make a note of the information we have. There are 5 ice-creams. 5 ice-creams cost $125.

Step 1: Let’s find the cost of 1 ice cream. In order to do that, divide the total cost of ice-creams by the total number of ice-creams. The cost of 1 ice-cream = Total cost of ice-creams/Total number of ice-creams = 125/5 = 25. Therefore, the cost of 1 ice cream is $25.

Step 2: To find the cost of 3 ice-creams, multiply the cost of 1 ice cream by the number of ice-creams. The cost of 3 ice-creams is cost of 1 ice-cream × number of ice-creams = 25 × 3 = $75. Finally, we have the cost of 3 ice-creams i.e. $75.

Given:

Kerry charges $25.50 per lawn to cut grass on Saturdays

and $28.50 per lawn to cut grass on Sundays.

If 4 lawns cuts in Saturday then the charges would be

=25. 50 x 4

=102

and, If 5 lawns cuts in Sunday then the charges would be

=28. 50 x 5

=142.5

Hence, the total she will earn 244.50.
