Answer:

y=1/3x+3

Step-by-step explanation:

We can write this in a y=mx+b format.

b is the y-intercept and m is the slope.

The y-intercept is where x=0, or where the line intersects the y-axis. We can see that there is a point on the y-axis: (0,3). Therefore, the y-intercept, or b, is 3.

So far, we have y=mx+3.

Now we can find the slope with rise over run. (rise being the change in y and the run being the change in x.)

From one point to the other, it goes up 1 (the rise) and over 3 (the run).

m=rise/run=1/3.

y=1/3x+3.

Hope this helped.

Answer:

The first one is 14.5 and the second one is that the decimal moves to the left every time a zero is added to the first number

Step-by-step explanation:

Answer:

1. 14.5

2. 100/5=20. If you move the decimal places for both numbers, it would be the same thing. 10 and 0.5 were moved one decimal place to the left so the answer is still 20.

Step-by-step explanation:

1.

   14.5

3/43.5

 -3

    15

Notice the decimal place of all the choices, they each match.

The restriction is that x ≠ -4 is not in the domain of the given function.

Function, in mathematics, an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).

The given function is

[tex]f(x)=\frac{x-1}{x+4}[/tex]

This is not defined when the denominator is zero.

Hence the restriction is on the denominator.

This implies that

[tex]x+4 \neq 0[/tex]

[tex]x\neq-4[/tex]

The restriction is that x ≠ -4 is not in the domain of the given function.

Answer:

the scale factor is 3

Step-by-step explanation:

Answer: See explanation

Step-by-step explanation:

1. Step 1: Add up all the numbers.

12 + 15 + 10 + 15 + 11 + 12 + 15 = 90

Step 2: Count how many numbers there are.

There are 7 numbers

Step 3: Divide the sum of the numbers by amount of numbers.

90 ÷ 7 = 12.85

12.85 ≈ 12.9

Mean = 12.9 in tenth place or 13 in whole place

2. The mode is the number that appears the most

15 appears 3 times.

3. 38 / +38

4. 1 week = 7 days

7 × 2 = 14

9 weeks = 9 × 7 = 63

63 × 3 = 189

189 + 14 = 203

203 miles in all

5. Area of 1st rectangle: b × h

4 × 14 = 56

Area of 2nd rectangle: b × h

4 × 14 = 56

56 + 56 = 112

Area of polygon = 112

Hope this helps!
