Answer:

21, -4, 5

Step-by-step explanation:

In the function we are changing x into -5 :

So :

(-5)² - 4

25 - 4 = 21

f(0) will be :

0² - 4

0 - 4 = -4

f(3) will be :

(3)² - 4

9 - 4 = 5

In linear equation ,242 total number of members within 5 weeks.

What is linear equation ?

a manual computation on how 1 member recruits his members until week 5. Then multiply the sum by 2.

                            old      new

1:   1

2:   1 x 3 = 3 ⇒        1         3       *only new members recruit 3 more

3:   3 x 3 = 9 ⇒        4         9

4:   9 x 3 = 27⇒     13       27

5: 27 x 3 = 81 ⇒    40       81

40 + 81 = 121. Total number of members under 1 founding member.

121 x 2 founding members = 242 total number of members within 5 weeks.

Answer: Option C

Step-by-step explanation:

1. y = 5x + 15.

2. y = total cost

x = number of calendar

m = cost per calendar = slope = 5

b = initial value/y-intercept = 15

3. $1,015.

4. The equation in slope-intercept form is: y = 5x + 15

5. Slope (m) = 5

6. y-intercept (b) = 15; x-intercept = -3.

7. See attachment below for the graph.

Using the information given, we can create an equation in slope-intercept form y = mx + b, where m would be the slope and b would be the y-intercept of the linear equation.

Let,

1. To create an equation that models the situation, substitute m = 5 and b = 15 into y = mx + b:

y = 5x + 15.

2. The variables and numbers in the equation are:

y = total cost

x = number of calendar

m = cost per calendar = slope = 5

b = initial value/y-intercept = 15

3. Substitute x = 200 into y = 5x + 15

y = 5(200) + 15

y = 1,015

Total cost = $1,015.

4. The equation in slope-intercept form is: y = 5x + 15

5. The slope (m) = 5

6. The y-intercept (b) = 15

To find the x-intercept, substitute y = 0 into y = 5x + 15

0 = 5x + 15

-5x = 15

x = 15/-5

x = -3

The x-intercept = -3.

7. See attachment below for the graph.

The ordered pair given are not inverse to each other because:

When two functions are inverse to each other substituting a value A in function say AA will give answer say X, substituting the answer X to the the other function say BB returns the value A.

Instance

say function AA, plug in A gives X

the inverse will be:

say function BB plug in X gives A

So, we have  f(x)=2x+5 and g(x)= x-5/2

plugging in say 5/2 in f(x) will give

f(x) = 2 * 5/2 + 5

f(x) = 5 + 5

f(x) = 10

We plug in 10 to g(x)= x-5/2

g(x) = 10 - 5/2

g(x)= 7/2

since 7/2 ≠ 5/2 the pair of functions are not inverse to each other

Step-by-step explanation:

Based on the concentration of the saline solution and the cubic centimeters of the saline solution, the amount that should be mixed is 140 cubic centimeters

Assuming that the quantity of the saline solution that Kent should mix is denoted by x, the formula would be:
0.08x + (0.18 x 60) = 0.11 (x + 60)

Solving gives:

0.08x + 10.8 = 0.11x + 6.6

10.8 - 6.6 = 0.11x - 0.08x

4.2 = 0.03x

x = 4.2 / 0.03

x = 140 cubic centimeters

In conclusion, 140 cubic centimeters of the saline solution is needed.

∠ C = 50°

Step-by-step explanation:

• each lower base angle is supplementary to the upper base angle on the same side.

then

∠ C + ∠ D = 180°

∠ C + 130° = 180° ( subtract 130° from both sides )

I don't know and your read in which class

====================================================

Reason:

Focus on the numerator for now. The [tex](11^8)^2[/tex] is the same as [tex]11^{16}[/tex] because we multiply the exponents. The general rule is [tex](a^b)^c = a^{bc}[/tex]

Alternatively we can think of it like this

[tex](11^8)^2 = (11^8)(11^8) = 11^{8+8} = 11^{16}[/tex]

So far we have [tex]\frac{(11^8)^2}{11^3} = \frac{11^{16}}{11^3}[/tex]

------------

The last step is to subtract exponents due to the rule [tex]\frac{a^b}{a^c} = a^{b-c}[/tex] and the order of subtraction is important.

Therefore, [tex]\frac{(11^8)^2}{11^3} = \frac{11^{16}}{11^3} = 11^{16-3} = 11^{13}[/tex]
