A store buys 14 sweaters for $154 and sells them for $448. How much profit does the store make per sweater?

Answers

Answer:

Profit = $21

Step-by-step explanation:

14 sweaters = $154

Cost of 1 Sweater = 154 ÷ 14

= $11

New Cost for 14 Sweaters = $448

New Cost of 1 Sweater = 448 ÷ 14

= $32

Profit Per Sweater = 32 - 11

= $21

Full Profit = 448 - 154

= $294

Write the equation of the line in fully simplified slope-intercept form. ​

Answers

Answer:

 y = 4/3x - 3

Step-by-step explanation:

1. Find two pints on the line: ((3,1) and (6, 5).

2. Find the slope: Slope = (change in y-values)/(change in the x-values).

   Slope = (5 - 1)/(6 - 3) = 4/3

3. Use the slope and one point and substitute into y = mx + b to solve for "b"

     y = mx + b                 slope = 4/3   and point (3, 1)

      1 = 4/3(3) + b              4/3 · 3/1 =  12/3 = 4

      1 = 4 + b

      1 - 4 = b

       -3 = b

4.  Write the equation of the line: m = 4/3 and b = -3  Substitute into y = mx + b

      y = 4/3x - 3

16. The measures of the acute angles of a right triangle have a ratio of 2 :7.
What is the measure of the smaller angle?

Answers

Answer:

The smaller angle is 20 degrees.

Step-by-step explanation:

A triangle's interior angles must have a sum of 180 degrees. Hence the two acute angles must have a sum of 180-90=90 degrees.

Say that the angles have 2x and 7x length:

2x+7x=90

9x=90

x=10

Hence the acute angles have degrees 2*10=20, 7*10=70.

The smaller angle is 20 degrees.

Answer:

  19. m = -3; f(x) = -3x +5

  21. m = 0; f(x) = 9

  24. m = -3/2; f(x) = -3/2x +18 1/2

Step-by-step explanation:

The slope of the function is given by the slope formula ...

   m = (y2 -y1)/(x2 -x1)

The y-intercept (b) can be found from the table when it includes a point (x, y) = (0, b). If the table doesn't have the y-intercept, it can be found from ...

  b = y -mx

When m and b are known, the slope-intercept equation is ...

  f(x) = mx +b

__

19.

  m = (11 -14)/(-2 -(-3)) = -3/1 = -3

The slope is -3. The function is f(x) = -3x +5.

__

21.

  m = (9 -9)/(2 -3) = 0/-1 = 0

The slope is 0. The function is f(x) = 9.

__

24.

  m = (14 -17)/(3 -1) = -3/2

  b = 17 -(-3/2)(1) = 18 1/2

The slope is -3/2. The function is f(x) = -3/2x + 18 1/2.

Find x in terms of the other letters a( x + b ) = c( x + d )

Answers

Answer:

[tex]x=\frac{cd-ab}{a-c}[/tex]

Step-by-step explanation:

The question is worded in a complicated way. All it says is to solve the equation for x. Do this by isolating x on one side of the equation.

First step is to distribute the a and c on either side,

ax+ab=cx+cd

Subtract cx from both sides,

ax+ab-cx=cd

Next, subtract ab from both sides,

ax-cx=cd-ab

Then, factor out x from the left side,

x(a-c)=cd-ab

Finally, divide both sides by a-c,

[tex]x=\frac{cd-ab}{a-c}[/tex]

If f(1) = 5 and f(n) = 4f(n − 1) - 2 then find the value of f(5).​

Answers

Hi,

This is the same situation as a sequence case.

You have two informations :

[tex]\left \{ {{f(1)=5} \atop {f(n)=4f(n-1)-2}} \right.[/tex]

You need to solve this rank by rank for n = 1, 2, 3, 4 and 5.

We already have f(n) for n = 1 : it is f(1) = 5.

n = 2 :

f(2) = 4 * f(2-1) - 2 = 4 * f(1) - 2 = 4 * 5 - 2 = 20 - 2 = 18 because f(1) = 5

n=3 :

f(3) = 4 * f(3-1) -2 = 4 * f(2) -2 = 4 * 18 -2 = 72 - 2 = 70

n = 4 :

f(4) = 4 * f(4-1) -2 = 4* f(3) - 2 = 4* 70 - 2 = 280 - 2 = 278

n = 5 :

f(5) = 4 * f(5-1) - 2 = 4*f(4) - 2 = 4 * 278 - 2 = 1112 - 2 = 1110

so f(5) = 1110

What is the average rate of change of the function f(x)=4x^2+3x on the interval [1,5]

Answers

Answer:

7, though I don't know if it's 100% correct. I tried to help.

Step-by-step explanation:

f(x) = 4x^2 + 3x interval [1,5]

f(1) = 4(1)^2 + 3(1)

f(1) = 4 + 3

f(1) = 7

Answer:

[tex]\boxed {\boxed {\sf 27}}[/tex]

Step-by-step explanation:

The average rate of change is the change in the output from one input to another. Essentially, it is the change in y over the change in x.

[tex]\frac {\Delta y}{\Delta x} = \frac { f (x_2)- f(x_1) }{x_2-x_1}[/tex]

Let's assign 1 to x₁ and 5 to x₂.

[tex]\frac {f(5)-f(1)}{5-1}[/tex]

We must find the outputs f(5) and f(1). Substitute the value in for each x in the function.

f(x)= 4x² + 3x

f(5) = 4(5)² + 3(5) f(5)= 4(25) + 15 f(5) = 100 + 15 =115

f(1)= 4(1)² + 3(1) f(1)= 4(1) + 3 f(1)= 4+ 3 =7

Now we can find the average rate of change. We know the outputs and we know the inputs.

[tex]\frac {f(5)-f(1)}{5-1}[/tex]

[tex]\frac {115 -7}{5-1}[/tex]

[tex]\frac {108}{4}[/tex]

[tex]27[/tex]

The average of change of the function f(x) = 4x² + 3x on the interval [1,5] is 27.

please help !! find the measure of ∠1 and ∠2. justify your answers

Answers

Answer:

angle 1 = 45° because vertical angles

angle 2 = 135° because supplementary angles

Step-by-step explanation:

∠1 = ∠a, ∠a = 45°

∠2 + ∠a (45°) = 180°

180° - 45° = 135°

Answer:

Angle 1= 45 degrees, angel 2= 135

Step-by-step explanation:

you know that line b has a 45 degree angle on a 180 total, so to find angle 1 you just move the 45 as they are the same, to find angle b you substract 45 from 180 getting 135
