Answer:

the systems of equations corresponding to the given solutions, in order

Step-by-step explanation:

Answer:

P' (-7, -4) , Q' (7, -8) , R' (-8, 4)

Step-by-step explanation:

Reflection in the y -axis:

The rule for a reflection over the y-axis is (x, y) → (−x, y).

P (7, -4) → P' (-7, -4)

Q (-7, -8) → Q' (7, -8)

R (8, 4) → R' (-8, 4)

Answer:

y = 7/4x - 3

Step-by-step explanation:

y = mx + b

y = 7/4x - 3

Answer:

I do not understand she question do you mean the sum of their income is 2640

if so, then the answer is 440 to be x income

Step-by-step explanation:

x income = 20% or 1/5 of y income

y income = 5 of x income

we know that the sum of their income = 2640

which means that

x + y = 2640 =

1/5y + y = 2640

6y/5 = 2640

cross multiply to give us

6y = 5(2640)

6y = 13200

divide through by 6 to give us,

6y/6 = 13200/6

y = 2200

since we know that x income is 20% y income,

therefore, x income =

20/100 * 2200

= 440

therefore,

x income = 440

y income = 2200

Isolate the variable by dividing each side by factors that don't contain the variable and solve for x.

Answer:

188cm³

Step-by-step explanation:

Answer:  Let the 2 numbers be x and  

sum of two numbers is 28....Eq 1:  x + y = 28

sum of 6 times the 1st number and 3 times the 2nd number is 105....Eq 2:  6x + 3y = 105

Rearrange Eq 1 to solve for x.

x + y = 28

x = 28 - y  --> Substitute into Eq 2, you get

6(28 - y) + 3y = 105

168 - 6y + 3y = 105

-3y = -63

y = -63 / -3 = 21

Now solve for x using Eq 1.

x = 28 - y = 28 - 21 = 7

Answer: x intercept is (-6,0) and y intercept is (0,-3)

Step-by-step explanation: the y intercept is when x=0. the x intercept is when y=0.

to solve this for the y intercept, we set x=0 in the equation y=-1/2x-3. so it would be y=-1/2(0)-3 therefore y= 0-3 and y=-3. the y intercept is (0,-3)

to solve for the x intercept, we set y=0. we plug it into the equation y=-1/2x-3 so 0=-1/2x - 3. this means we can change the sign of -1/2x from negative to positive and move it to the other side. so 1/2x=-3 to solve for x, we divide both sides by 1/2 so x=-6. so the x intercept is (-6,0)

Answer:

56 Burgers

Step-by-step explanation:

First, add the 3 + 4 for a total of 7, because the total of the ratio will equal the total amount of "the dinners sold".

Then divide 98/7, which will give you 14.

Then in the ration 3:4, 4 represent burgers so multiply 14 x 4.

Which gives you 56 burgers.

Answer:

Answer:

1225.50

Step-by-step explanation:

14% of 1075 =0.14 x 1075=150.5

1075 +150.5 = 1225.5

The 14% of $1075 is $150.5 thus the total cost for the hotel room overall 5 nights including tax will be $1225.50.

The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.

The percentage is also called the indicating hundredths. Thus, 2% is two-hundredth, which means 2%=2/100=0.02.

As per the given,

The total cost before tax was $1,075.

The tax rate is 14%

14% of $1075 will be,

(14/100)1075 = $150.5

Total cost includes tax = $1075 + $150.5 = $1225.50

Hence "The 14% of $1075 is $150.5 thus the total cost for the hotel room overall 5 nights including tax will be $1225.50".

Answer:

x = 9

AB = 9

BC = 15

Step-by-step explanation:

x + x + 6 = 24

2x + 6 = 24

2x = 24 - 6

2x = 18

x = 18 / 2

x = 9

AB = x = 9

BC = x + 6

= 9 + 6

BC = 15

Answer:

Just as one die has six outcomes and two dice have 62 = 36 outcomes, the probability experiment of rolling three dice has 63 = 216 outcomes. This idea generalizes further for more dice. If we roll n dice then there are 6n outcomes.

We can also consider the possible sums from rolling several dice. The smallest possible sum occurs when all of the dice are the smallest, or one each. This gives a sum of three when we are rolling three dice. The greatest number on a die is six, which means that the greatest possible sum occurs when all three dice are sixes. The sum of this situation is 18.

When n dice are rolled, the least possible sum is n and the greatest possible sum is 6n.

Step-by-step explanation:

Answer: 4(5y−2)=40

Divide both sides by 4.

5y−2=  

4

40

​

Divide 40 by 4 to get 10.

5y−2=10

Add 2 to both sides.

5y=10+2

Add 10 and 2 to get 12.

5y=12

Divide both sides by 5.

y= 12/5 or 2.4 please give brainliest

50°

Step-by-step explanation:

40° + 90° + ? = 180°

130° + ? = 180°

? = 180° - 130°

? = 50°

Answer: 50 degrees

Step-by-step explanation: The interior angles add up to 180.

1. 40 + 90 + ? = 180

     130 + ? = 180

   -130         - 130
