What is the definition of rate of change?

Answer:

The answer is 77 degrees

Answer:

y=7x/4-3

Step-by-step explanation:

We can use the formula y=mx+b. m=slope so y=7/4x+b. We know that the line intersects the point (0,-3) so we plug it in, x=0 and y=-3. -3=(7/4)*0+b. b=-3. Therefore, the equation is y=7x/4-3.

Answer:

The resulting line will be the same for all three because the verbal statement, the equation, and the table all represent the same situation. They just do it in different ways.

Answer:

x=-3. y=-5

Step-by-step explanation:

Equating both equations,

6x + 13 = 2x + 1

6x - 2x = 1 - 13

4x = -12

x = -3

Plug in the value of x in the given first equation,

y = 6* (-3) + 13 = -18 + 13 = -5

Answer:

{y,x} = {-5,-3}

Step-by-step explanation:

System of Linear Equations entered

y - 6x = 13

 y - 2x = 1

Graphic Representation of the Equations

-6x + y = 13        -2x + y = 1  (attached)

Solve by Substitution

y = 2x + 1

(2x+1) - 6x = 13

   - 4x = 12

4x = - 12

    x = - 3

  y = 2x+1

   x = -3

 y = 2(-3)+1 = -5 (final answer)

hope it helps you!

Answer:

-7.5

Step-by-step explanation:

Whole numbers are natural numbers from 0 to infinity. This does not include decimals or fractions. For example, these numbers are 0, 1, 2, 3, 4...

Integers are whole numbers, but they include negative numbers. So, from negative infinity to positive infinity. This does not include decimals or fractions. For example, these numbers are ... -3, -2, -1, 0, 1, 2, 3 ...

A rational number is any number that can be expressed as a fraction. So, this includes -7.5, as -7.5 can be expressed as -[tex]\frac{15}{2}[/tex].

Therefore the answer is -7.5.

Part A: Create an equation that shows the amount of money earned, E, for working x hours in a week when there is no overtime. (3 points)

x hours in a week and there is no overtime and x <= 35 so equation:

E(x) = 16x

Part B: Create an equation that shows the amount of wages earned, T, for working y hours of overtime. Hint: Remember to include in the equation the amount earned from working 35 hours. (3 points)

Regular hours = E(x) = $16 x 35 = $560

T(y) = 21y + 560

Part C: Marco earned $602 in 1 week. How many hours (regular plus overtime) did he work? Show your work. (4 points)

21y + 560 = 602

21y = 42

y = 2

Marco worked 37 hours (35 regular plus 2 hours overtime)

Answer:

10:8 or 10 to 8

both the same thing worded differently.

Step-by-step explanation:

There are 10 erasers and 8 pencils so you say 10:8

Answer:

2

Step-by-step explanation:

Two negatives makes a positive, - (-6) can be rewritten as +6 or simply just 6.

Proceed to do simple calculations, 6 - 4 = 2.

Answer:

2

Step-by-step explanation:

Multiply the -6 by -, and it equals a positive 6 (When you multiply a negative number by a negative number it becomes a positive).

Finish the equation by subtracting 6 - 4 = 2

I know it might not make sense but trust me, I had to do problems like this.

Hope this helps!

Answer:

i need a graph to answer this

Step-by-step explanation:

Answer:

the first one is (6.5,13)

the second one is (4,4)

Step-by-step explanation:

-2x-0=-13    

-2x=-13 divide -2 by -13

x=6.5

-2(0)-1y=-13

0-1y=-13

-1y=-13

13

so that gives you (6.5,13)

2x+2(0)=8

2x+0=8

2x=8 divide two by eight

x=4

2(0)+2y=8

0+2y=8

2y=8 divide two by eight

y=8

Answer:

6

Step-by-step explanation:

Answer:

6

Step-by-step explanation:

Since there are two white bars (which equals 4 each) it equals 8.

There are 2 shaded blocks (which equals -2 each) and that amounts to -2.

8 - 2 = 6

Answer:

He can fit 2 more DVD's on the shelf.

And he'll have about 12 mm of extra space left.

Step-by-step explanation:

40×1.4 = 56cm  This is the length of space the 40 DVD's will take up.

60-56 = 4cm  This is the amount of space left.

4/1.4 = 2.857   the number of DVD's that will fit.

Of course, the decimal represents a partial DVD which is worthless.

Just to be sure, 2×1.4 = 2.8cm OK. But  3×1.4=  4.2cm which is 2mm too much

Answer/explanation:

Given:

m<8 = 23°

a. m<1 = 180° - m<8 (corresponding angles theorem and supplementary angles theorem)

m<1 = 180 - 23 = 157°

b. m<2 + m<1 = 180° (linear pair)

m<2 + 157° = 180°

m<2 = 180° - 153° = 23°

c. m<3 = m<1 (vertical angles are congruent)

m<3 = 157°

d. m<4 = m<2 (vertical angles are congruent)

m<4 = 23°

e. m<5 = m<1 (corresponding angles)

m<5 = 157°

f. m<6 = m<8 (vertical angles are congruent)

m<6 = 23°

g. m<7 = m<5 (vertical angles are congruent)

m<7 = 157°

Answer: 60%

Step-by-step explanation:

Given: Climbing rate at the end of week 1 = 25 steps per minute.

Climbing rate at the end of week 4 =   60 steps per minute

The  percent increase in Maggie's rate of climbing steps from the end of week 1 to the end of week 4 will be :

[tex]\dfrac{\text{Climbing rate after week 4 - Climbing rate after of week 1}}{\text{Climbing rate after week 1}}\times100[/tex]

[tex]=\dfrac{40-25}{25}\times100\\\\=\dfrac{15}{25}\times100=15\times4=60\%[/tex]

Hence, the percent increase in Maggie's rate of climbing steps from the end of week 1 to the end of week 4 = 60%

Answer:

Step-by-step explanation:

rm x 3/11 ÷ 3/11

Answer:

{the question is asking to find the value of x not m}

The value of x is 9°

Step-by-step explanation:

8x-2°+47° = 12x+9°{an exterior angle formed by producing the side of triangle is equal to two non adjacent angle}

or, 8x+45° = 12x+9°

or, 8x-12x = 9°-45°

or, -4x = -36°

or, x = -36°/-4

or, x = 9°
