helpppp pleease. point p (-2 -3) is reflected across line L. its image is point Q(8, 12). Find the equation of line L. Describe the steps you took.

Answer:

y = -2x  - 2

Step-by-step explanation:

Slope intercept form of equation is y = mx + c

c is intercept and m is slope

given that slope is -2

m = -2

thus, equation in slope intercept will be

y = -2x + c

The given line passes through (-1,0)

y = -2x + c

lets substitute y = 0 and x = -1 in the given equation

0 = -2*-1 + c

0 = 2 + c

c = -2

Thus, the complete slope intercept equation after using the value of c as -2

we have

y = -2x  - 2   answer

Answer:

6 toppings

Step-by-step explanation:

The pizza is charged to 9$ per pizza and topping are 1.25, but heatehr bought it for 15.25$, so all you have to do is the full amount minus the price the pizza is so, 15.25-9=6.25, but its toppings so round it to 6

Answer:

The cargo plane flew 1208 miles, and it took 4 hours.

Step-by-step explanation:

4608 miles is the distance between the passenger plane and the cargo plane.

This distance can be expressed as the sum of the distance that the passenger plane had flown and the distance that the cargo plane had flown.

Distance Apart = Distance Flown (Passenger) + Distance Flown (Cargo)

So, to find the distance flown by the cargo plane, we need both the distance between the 2 planes and the distance flown by the passenger plane.

We know that the distance apart is 4608 mi.

We can find the distance flown by the passenger plane by multiplying its speed by the time it was flying.

[tex]distance = speed * time[/tex]

Speed = 425 mph

Time = 8 hours

[tex]distance\ (passenger) = 425 * 8\\distance\ (passenger) = 3400[/tex]

The passenger plane flew 3400 mi.

Now we can find the distance flown by the cargo plane:

Distance Apart = Distance Flown (Passenger) + Distance Flown (Cargo)

[tex]4608 = 3400 + distance[/tex]

Subtract 3400 from both sides:

[tex]1208 = distance[/tex]

The cargo plane flew 1208 miles.

If we want to find for how long it flew, we can divide the distance by its speed.

[tex]distance = speed * time[/tex]

[tex]time = \frac{distance}{speed}[/tex]

Distance = 1208 mi

Speed = 302 mph

[tex]time = \frac{1208}{302} = 4[/tex]

Answer: The cargo plane flew 1208 miles, and it took 4 hours.

Answer:

500,000

Step-by-step explanation:

200,000 + 100,000 = 300,000 = pump B

300,000 + 200,000 = 500,000

Pump B + Pump A = Total Amount

Answer:

23

Step-by-step explanation:

If you have something that says it is the f(x) or just f(something) then that is just telling you what the x equals. In this case, x=4 so you plug that into the equation.

This gives you f(4)=4(4)+7. From here, you will use the order of operations to solve.

f(4)=4*4+7

f(4)=16+7

f(4)=23

Answer:

f(4)=23

Step-by-step explanation:

1.f(4)=4(4)+7

2.f(4)=16+7

3.f(4)=23

Answer:

b

Step-by-step explanation:

The decimal number 3.4 terminating decimal. So, it is rational number. Therefore, option B is the correct answer.

Rational numbers are in the form of p/q, where p and q can be any integer and q ≠ 0. This means that rational numbers include natural numbers, whole numbers, integers, fractions of integers, and decimals (terminating decimals and recurring decimals).

A) The decimal number 3.456733244… is not repeating and non recurring

So, it is irrational number

B) The decimal number 3.4 terminating decimal

So, it is rational number

C) Infinity is not a rational number because it is undefined as far as being an integer.

D) ∛4 =1.58740105197 is not repeating and non recurring

So, it is irrational number

The decimal number 3.4 terminating decimal. So, it is rational number. Therefore, option B is the correct answer.

0,2x =-6

x=-6 :0,2

x=-30

Hey there!

Your answer would be -32.5.

First, you would multiply both sides by 10, and simplify. That would bring you to 4x + 25 = 2x - 40. Now you can start isolating the varible. Subtract 25 from both sides, and simplify. That gives you 4x = 2x - 65. Next, subtract 2x from both sides, and simplify once again. That brings you to 2x = -65. Finally, divide both sides by 2 and once more, simplify. It gives you your answer x=-65/2 or -32.5

Answer:

u=2

Step-by-step explanation:

8u-21 = 2u-9

+21             +21

8u= 2u + 12

-2u    -2u

6u= 12

divide by 6, u=2 !!

Answer:

u = 2

Step-by-step explanation:

8u - 21 = 2u - 9

subtract 2 u from both sides

6u - 21 = -9

add 21 to both sides

6u = 12

divide both sides by 6

u = 2

hope this helps

Answer:

1) 3²=9 so the statement is FALSE

2) √64=8 so the statement is TRUE

3) the statement is TRUE

4) (-2)³=-8 so the statement is FALSE

x = 5

explanation

70 + 23x - 5 + 110 + 14x = 360

first you group the like terms

23x + 14x + 70 - 5 + 110 = 360

then combine the like terms

23x + 14x    70 - 5 + 110

37x + 175 = 360

subtract 175 from both sides

175 - 175 = 0     360 - 175 = 185

to get

37x = 185

divide both sides by 37

37x/37 = 0     185/37= 5

which gives you

x = 5
