I need help quocl

Answers

Answer:

-2m - 5n + 12

Step-by-step explanation:

Simplify:

(4m + 7) + (- 5n + 4) + (- 6m + 1) = 4m + 7 - 5n + 4 - 6m + 1 = (4 - 6)m - 5n + 12 = -2m - 5n + 12

Answer:

[tex](4m + 7) + ( - 5n + 4) + ( - 6m + 1) \\ = 4m + 7 - 5n + 4 - 6m + 1 \\ = \boxed{- 2m - 5n + 12}✓[/tex]

(-2m-5n+12) is the right answer.

A cyclist travels 12 miles in 45 minutes.
What is his average speed in mph?

Answers

Pretty sure it is 16 mph

Answer: 16 mph

Step-by-step explanation: To get speed in mph.

Divide the miles by the time. First we can change minutes to hours.

45/60 = 3/4 hour

12 divided by 3/4 hour is 12 ÷ 3/4

Invert the denominator and multiply:

12 × 4/3

16 mph

what is my average grade if i have seven 100's and one 0

Answers

Answer:

90/100 or 81.8%

Step-by-step explanation:

w = 0,1 , then your grade will be 81

It depends upon how many total points are available and what the zero was out of possible points. If you have a 90/100 and a 0/100, that gives you a 45%, which is failing. If you have 90% of 1000 points and get a 0/100, that will land you with an 81.8%.

Answers

Answer:

Point A: (-3,3)

Point B: (3, -2.5)

Point C: (-4, -4)

point D: (1,0)

Step-by-step explanation:

Answer:

1. Point A (-3, 3)

2. Point B (3, -2.5)

3. Point C (-4, -4)

4. Point D (1, 0)

Explanation:

to identify the coordinates of each point, begin by locating where the point is across from the x axis and y axis.

These coordinates are in the form (x, y)

where x is the horizontal [left and right] orientation or location in respect to the x axis, and y is the vertical [up and down] orientation or location in respect to the y axis.

Point A is 3 units to the left and 3 units up from the origin [(0, 0)] so the coordinate of this point is (-3, 3).

Point B is 3 units to the right and 2.5 units down from the origin [(0, 0)] so the coordinate of this point is (3, -2.5).

Point C is 4 units to the left and 4 units down from the origin [(0, 0)] so the coordinate of this point is (-4, -4).

Point D is 1 unit to the right and 0 units down from the origin [(0, 0)] so the coordinate of this point is (1, 0).

what is x's value 4x+4y=44 y=2x+2

Answers

Answer: x = 11 + y

Step-by-step explanation: Simplifying

4x + -4y = 44

Solving

4x + -4y = 44

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '4y' to each side of the equation.

4x + -4y + 4y = 44 + 4y

Combine like terms: -4y + 4y = 0

4x + 0 = 44 + 4y

4x = 44 + 4y

Divide each side by '4'.

x = 11 + y

Simplifying

x = 11 + y

I need help with a geometry problem! It’s about reflection

Answers

Step-by-step explanation: Here, we're asked to reflect ΔQRS over

the x-axis so we begin by reflecting point Q over the x-axis.

Since point Q is 2 units below the x-axis, point Q will reflect

over the x-axis to a position 2 units above the x-axis.

We label this point as Q' which is the ordered pair (1, 2).

Next we reflect point R over the x-axis.

Since point R is 2 units below the x-axis, point R will reflect

over the x-axis to a position 2 units above the x-axis.

We label this point as R' which is the ordered pair (3, 2).

Now connect the points to get our reflection.

Next we reflect point S over the x-axis.

Since point S is 6 units below the x-axis, point S will reflect

over the x-axis to a position 6 units above the x-axis.

We label this point as S' which is the ordered pair (1, 6).

Answer:

The value of a = -12

Step-by-step explanation:

Given the equation

[tex]\frac{8^{-55}}{8^a}=8^{-43}[/tex]

Determining the value of a

Given the equation

[tex]\frac{8^{-55}}{8^a}=8^{-43}[/tex]

Apply the exponent rule: [tex]\frac{x^a}{x^b}=x^{a-b}[/tex]

[tex]\:8^{-55-a}=8^{-43}[/tex] ∵ [tex]\frac{8^{-55}}{8^a}=8^{-55-a}[/tex]

[tex]-55-a = -43[/tex]

Add 55 to both sides

[tex]-55-a+55=-43+55[/tex]

Simplify

[tex]-a=12[/tex]

Divide both sides by -1

[tex]\frac{-a}{-1}=\frac{12}{-1}[/tex]

Simplify

[tex]a=-12[/tex]

Therefore, the value of a = -12
