Step-by-step explanation:

f(x) = 1-3x, x = 4 , x = 4+h

(a) find the net change of f(x):  

f1= f(x=4) = 1-3(4) = 1 - 12 = -11

f2= f(x=4+h) = 1-3(4+h) = 1-12 + 3h = -11 - 3h

Net change = f2 - f1 = -11 -3h - -11 = -3h

(b) average rate of change = slope = (f2 - f1)/(x2-x1) = -3h/((4+h)-4 =-3

Answer:

10 pairs

22.50x+6.50<_250

Step-by-step explanation:

If you do 22.50 times 10 you get 225 then you add 6.50 which would give you 231.50. You cant add any more pairs of shoes because you would go over the $250 limit. For example if you added 22.50 one more time you would be at 254. Therefore it would be 10 pairs of shoes.

Answer:

I see no solution.

Step-by-step explanation:

The sum of the angles of a triangle is 180°

Given

x+ x + 10 +y = 180. and

2x -50 + 50 + y = 180

y represents the angles with no value indicated.

Simplifying:

2x +y +10 = 180

2x + y = 180

This looks like a no solution system.

If I'm missing something, I hope someone else can explain it.

The two triangles are similar when two angles of the triangle are equal.

The possible value of x which the two triangles are similar is x = 60°

Reasons:

Required;

To find the values of x for which the two triangles are similar

Method:

Given that two angles of the triangle are specified, the triangles can be

similar for only one value of x.

Solution:

The two triangles are similar when we have;

x + 10° = 2·x - 50°

Which gives;

2·x - x = 50° + 10° = 60°

x = 60°

Checking gives;

x + 10° = 2·x - 50° = 70°

Two angles of the first triangle are;

70° and 60°

The third angle of the first triangle is (180° - (70° + 50°)) = 60°

The three angles of the first triangle are therefore; 70°, 60° and 50°.

Two angles of the second triangle are;

70° and 50°

The third angle of the second triangle is (180° - (70° + 50°)) = 60°

The three angles of the second triangle are therefore; 70°, 60° and 50°

Therefore, the two triangles are similar by AAA similarity.

When x = 50°, we have;

x + 10° gives;

50° + 10° = 60°

∴ ∠(x + 10°) = 60°

The two angles of the first triangle are; 60° and 50°

The third angle on the second triangle is 180° - (60° + 50°) = 70°

On the second triangle, we have;

2·x - 50° gives;

2 × 50° - 50° = 50°

∴∠(2·x - 50°) = 50°

Therefore, the two angles of the second triangle are; 50° and 50°

The third angle on the second triangle is 180° - (50° + 50°) = 80°

Therefore, the two triangles are not similar when x = 50°

Similarly, the two triangles are not similar when x + 10° = 50°

Therefore;

The possible value of x which the two triangles are similar is x = 60°

2.88

Step-by-step explanation:

Consider this quadratic equation.

x ^2+ 2x + 7 = 21

Subtract 7 from both sides

x ^2+ 2x + 7 -7= 21-7

x^2+2x = 14

x^2+2x -14 = 0

Factorize

x = -2±√2²-4(-14)/2

x= -2±√4+56/2

x = -2±√60/2

x = -2±7.75/2

x = -2-7.75/2 and -2+7.75/2

x = -9.75/2 and 5.75/2

x = -4.88 and 2.88

Hence there are 1 number of positive solution

Answer:

  c) points: (0, 600), (1, 400); equation: y = 100 +500·(0.6^x)

Step-by-step explanation:

c) It is convenient to choose points that are on the grid intersections. Two such points are ...

  (0, 600) and (1, 400)

From part (a), you know that the horizontal asymptote is 100, so this is the value that is added to the exponential function. That is, the exponential term of the function decays from 600-100 = 500 at x=0 to 400 -100 = 300 at x=1. The "growth factor" is then 300/500 = 3/5 = 0.6.

The exponential equation is then ....

  y = (horizontal asymptote) + (initial exponential term)(growth factor)^x

Using the numbers we just developed, this is ...

  y = 100 + 500(0.6^x)

Answer:

For $1 its 12.5lbs

Step-by-step explanation:

Answer:

6 units

Step-by-step explanation:

AM = MC

AM = x + 20

MC = 5x - 4

x + 20 = 5x - 4

20 = 4x - 4

24 = 4x

x = 6

The required length of the AM is 27.

Given that,
M is the midpoint of line segment AC,
AM = x + 20, and MC = 5x - 4.
To find the length of AM.

The midpoint is that point the line whose distance from both the ends of the line is equal.

Here,
M is the midpoint of line segment AC, i.e.
AM = AC                             - - - - - - - - - - -- - - (1)
AM = x + 20, and MC = 5x - 4
Put  AM and MC in equation 1

x + 20 = 5x - 4
5x - x = 20 + 4
4x = 24
x = 24 / 4

x = 7

Now,
Length AM =  x + 20
Length AM =  7 + 20
Length AM =  27

Thus, the required length of the AM is 27.

Answer: 32 sq.cm

Step-by-step explanation:

If you think of it as there being 2 squares instead of 1, you can think well since the whole one side of the rectangle is 8cm and the half side is 4 then that must mean that the other square that you just divided up must be 3 by 4 so then you can multiply those and get 12 and you do the same for the other one which would be 4 by 5 and when you multiply those you will get 20 and when added you get 32.

Answer:

11

Step-by-step explanation:

first 3-2=1 the divide 90 by 3 then add the 1 the subtract that by 20 and you will get 11

The result of the expression 90 divided by 3 plus the quantity (3 minus 2) minus 20 is 11.

To evaluate the expression 90 divided by 3 + (3 - 2) - 20, we can follow the order of operations (also known as PEMDAS/BODMAS), which stands for Parentheses/Brackets, Order/Exponents, Division/Multiplication, and Addition/Subtraction:

First, let's simplify the expression within the parentheses:

3 - 2 = 1

Now we can substitute the simplified expression back into the main expression:

90 ÷ 3 + 1 - 20

Next, perform the division:

90 ÷ 3 = 30

Now we have:

30 + 1 - 20

Next, perform the addition:

30 + 1 = 31

Finally, perform the subtraction:

31 - 20 = 11

Therefore, the value of the expression 90 divided by 3 + (3 - 2) - 20 is 11.
