Answer:

y = 7x-17

Step-by-step explanation:

y=mx+ c

substitute the values,

-3=14+c

c=-17

y=7x-17

Answer:

25

Step-by-step explanation:

3 over 3 = 1

5 x (4-1)

5 x 4 = 20

5 x 1 = 5

20 + 5 = 25

Answer:

3/2

if you put the equation in slope intercept form you get y=3/2x-5

Answer:

  cost = 1.35n

  $33.75 for 25 songs

Step-by-step explanation:

Based on the numbers given, the cost is proportional to the number of songs downloaded. The constant of proportionality is the cost of one song: 1.35.

  cost = 1.35n

For 25 songs, ...

  cost = 1.35·25 = 33.75 . . . . dollars

__

The equation is ...

  cost = 1.35n

Answer:

60 Degrees

Step-by-step explanation:

Supplementary means it equals 180 together, so you divide it by 3 because the one is twice as big and you take the smaller answer

[tex]\frac{180}{3} =60[/tex]

Small and large angle are 60° and 120°.

Given that;

Angles are supplementary

Computation:

Assume;

Smaller angle = a

So,

Large angle = 2a

So,

In supplementary

a + b = 180

a + 2a = 180

3a = 180

a = 60

Smaller angle = 60°

Large angle = 2(60)

Large angle = 180°

Answer:

11/3

Step-by-step explanation:

Multiply the 3 by the 3 and then add 2.

Answer:

x = -11.2

Step-by-step explanation:

0.1 + 0.2x + 0.3 + 0.05x = -2.4

Combine like terms on the left side.

0.25x + 0.4 = -2.4

Subtract 0.4 from both sides.

0.25x = -2.8

Divide both sides by 0.25.

x = -11.2

Step-by-step explanation:Beacsue that is way smaller than usal...the angle is 180 degress so if you do 55+65=120 so it defintly isn't 120 because that is correct so ya.

Answer:

y=-3x+13

Step-by-step explanation:

y=-3x-9+4

-9+9= 0 so that cancel out

next u do

4+9=13

and thats when u drop the variables and the 13 down then it will be

y= -3x + 13

Answer:

y = x + 4

Step-by-step explanation:

Let the equation of the linear function represented by the table is,

[tex]y-y_1=m(x-x_1)[/tex]

where m = slope of the line

And this line passes through the points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]

Slope of the given line = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

From the given table two points lying on the function are (-4, 0) and (1, 5).

Slope 'm' = [tex]\frac{5-0}{1+4}[/tex] = 1

Therefore, equation of the linear function passing through (1, 5) and slope 1 will be,

y - 5 = (x - 1)

y = x + 5 - 1

y = x + 4

  the prediction was about 35% too low

Step-by-step explanation:

We generally define percent error as the difference between a measurement and an actual value, as a fraction of the actual value. Here, the actual value is 6.5 inches, so we can compute the error to be ...

  (4.25 -6.5)/6.5 × 100% = -34.6%

Burns' prediction was about 35% too low.

Answer:

4. 120

5. 20

6. 55

Step-by-step explanation:

All straight lines have a degree of 180, so the angle measures all have to add up to 180 degrees.

Answer:

4) 120°

5) 20°

6) 55°

Step-by-step explanation:

4) 180°-60°=120°

5) 180°-160°=20°

6) 90°+35 = 125°

   180°-125°=55°

Answer:

D

Step-by-step explanation:

Polynomials are always closed with addition, subtraction, and multiplication. Division cannot be used to close a polynomial because when you divide two polynomials, its not going to come out as polynomial. All the other operations after completed will create another polynomial.

The answer is x = 7

Step-by-step explanation:

Divide each term by  3  and simplify. Move all terms not containing  x  to the right side of the equation.

Answer:

[tex]\huge\boxed{x=7}[/tex]

Step-by-step explanation:

In order to solve for x, our goal is to isolate it on one side of the equation. We can do this by reversing the equation.

Let's apply the distributive property on the left side:

[tex](3 \cdot x) + (3 \cdot -10) = -9\\\\3x-30=-9[/tex]

Add 30 to both sides:

[tex]3x - 30 + 30 = -9 + 30\\\\3x = 21[/tex]

Divide both sides by 3:

[tex]3x \div 3 = 21 \div 3\\\\x = 7[/tex]

So x = 7.
