4/7

Step-by-step explanation:

4/7 is the slope of the line

Answer:

It has zero solutions since its a contradiction

Answer:

No Solution

Step-by-step explanation:

1/2x+6=1/4(2x-24)

Distribute numbers in parenthesis

1/2x+6=1/2x-6

When you try to move both of the x's to the same side, you are left with 0x

6≠-6

Therefore no solution

Answer: the rate of change is 1/2

Step-by-step explanation:

The formula for slope is y2 - y1/ x2 - x1

I picked points (2,2) (x1 & y1) and (6,4) (x2 & y2)

4 - 2 = 2

6 - 2 = 4

2/4 is the rate of change, and 1/2 is 2/4 simplified

Answer:15

Step-by-step explanation:

Answer:

$20.57

Step-by-step explanation:

First you have to find how many hours he/she works per week (38) and how many weeks he/she works a year (50) and how much he/she makes a year (39,095)

Now in order to find this we have two ways I will use the simpler way so it makes it easier to write and tell to you're teacher :)

First you multiply 50 and 38

50 × 38 = 1900

Since you know how much he/she makes a year you just divide.

39,095 ÷ 1900 = 20.57

So that makes your answer 20.57, Hope this helps and if it did and if I deserve it pls give brainlyest thank you :)

Answer: 0.27, 1/3, 1 1/4, 1.35

Step-by-step explanation:

Answer:

D. 0.27. 1/3. 1 1/4. 1.35

Step-by-step explanation:

1/3 = 0.3

1 1/4 = 1.25

1. 0.27

2. 0.3 or 1/3

3. 1.25 or 1 1/4

4. 1.35

Answer: {5, 1, 3}

Step-by-step explanation:
Plug in the numbers in parentheses for x.

a: f(-2) = 1-2(-2) = 1+4 = 5

b: f(0) = 1-2(0) = 1-0 = 1

c: f(2) = 1-2(2) = 1-4 = -3

Answer: 5, 1, -3

Step-by-step explanation:

1. f(-2) = 1-2x(-2) = 1+4 =5 ; f(-2)= 5

2. f(0) = 1-2(0) = 1-0 = 1 ; f(0) = 1

3. f(2) = 1-2(2) = 1-4 = -3 ; f(2) = -3

Answer: B

Explanation:

Correct way to write down co-ordinates: x,y

Dog 1's position: (-6,3)

Dog 2's position: (-6,-3)

Similarity: Both co-ordinates have -6 on the X axis (left to right line)

Difference: Dog 2's Y co-ordinate is NEGATIVE 3 while dog 1's Y co-ordinate is POSITIVE 3

The position is going to be reflected across the X axis because their X co-ordinates are the same, so dog 1 will be on the positive section for the Y axis (line that goes up and down) while Dog 2 will be on the negative section of the Y axis since it has negative 3 as its Y co-ordinate.

Answer:

ur  answer is 120 trust me and when u get it right give me brainly

Step-by-step explanation:

a) The step where Mardie first made an error is given as follows: Step 1, as the negative sign means that the sign of each term inside the parenthesis should be changed.

b) The correct expression is given as follows: -8.6b + 28.

The expression in the context of this problem is defined as follows:

(-3.78b + 12) - (4.82b - 16).

The negative sign before the parenthesis means that the sign of each term inside the parenthesis is changed, hence:

-3.78b + 12 - 4.82b + 16.

This is the step where Maddie made the first error.

Then, to simplify the expression, we combine the like terms, as follows:

b(-3.78 - 4.82) + 12 + 16 = -8.6b + 28.

Answer: 1/2, 0.51, 11/20

Step-by-step explanation:

Use 100 as a common denominator so you can compare all the numbers in like terms:

1/2 = 50/100

0.51 = 51/100

11/20 = 55/100

Answer:

[tex]\frac{1}{2} 0.51, \frac{11}{20}[/tex]

Step-by-step explanation:

First, you want to change the decimal into a fraction.  0.51= [tex]\frac{51}{100}[/tex]

Then, find the common denominator.  In my example, I used 100.  Find the equivalent fraction for the fractions with 100 as their denominator

[tex]\frac{11}{20} = \frac{55}{100} \\\\\ \frac{1}{2} = \frac{50}{100}[/tex]

Next, line them up in order of their numerators

[tex]\frac{50}{100} \frac{51}{100} \frac{55}{100}[/tex]

Finally, match the new fraction with their reduced fraction or decimal:

[tex]\frac{1}{2} = \frac{50}{100} \\\\0.51 = \frac{51}{100} \\\\\frac{11}{20} = \frac{55}{100}[/tex]
