Answer:

[tex]4x + 0.9 \geq 0.1[/tex] is equivalent to the inequality [tex]40x+9 \geq 1[/tex]

Step-by-step explanation:

Given inequality : [tex]4x + 0.9 \geq 0.1[/tex]

We are supposed to find Which of the following is equivalent to the inequality

[tex]4x + 0.9 \geq 0.1[/tex]

[tex]\Rightarrow 4x+\frac{9}{10} \geq \frac{1}{10}[/tex]

Multiply both sides by 10

[tex]\Rightarrow 4(10)x+\frac{9}{10}(10) \geq \frac{1}{10}(10)[/tex]

[tex]\Rightarrow 40x+9 \geq 1[/tex]

[tex]4x + 0.9 \geq 0.1[/tex] is equivalent to the inequality [tex]40x+9 \geq 1[/tex]

So, Option B is true

B) [tex]40x+9 \geq 1[/tex]

Step-by-step Answer:

Whenever we have a problem like this, we can have 2 solutions (either one can work) because, in absolute equations, we need to find how far away the number is from 0.

So the answer would simply be that a>2 and a<-2

a can be anything greater than 2 or a can be anything less than 2

Answer:

y = -5

Step-by-step explanation:

4y−3=5y+2

add 3 both sides

4y−3+3=5y+2+3

4y=5y+5

subtract 5y both sides

4y−5y=5y−5y+5

-y=5

divide both side by -1

-y/-1=5/-1

Answer:

20 chairs

Step-by-step explanation:

Since we are given the amount total budget and the total amount for the desks then the only variable missing is the maximum amount of chairs. This can be solved with the following equation in which s represents the number of chairs, and we simply solve for s.

800 = 320 + 24s  ... subtract both sides by 300

500 = 24s ... divide both sides by 24

20.83 = s

Now we see that the maximum number of chairs that the librarian can buy is 20 because 21 would make her go over the budget and you cannot have 0.83 of a chair.

Answer:

The librarian can buy a maximum of 20 chairs to stay within the budget.

Step-by-step explanation:

The total budget is:

T = 800

From that budget, he spends 320 on desks (D), so he has the remaining amount to buy chairs (C):

[tex] C = 800 - 320 = 480 [/tex]

Since each chair costs 24, and he has 480 he can buy the following number of chairs:

[tex] n = \frac{C}{24} = \frac{480}{24} = 20 [/tex]

Therefore, the librarian can buy a maximum of 20 chairs to stay within the budget.

The correct answer is

-1.5

Answer:

Option (A)

Step-by-step explanation:

Function to represent the cost of producing 't' tires is,

C(t) = -0.45t² + 12t + 450

Since average rate of change of the function in the interval (a, b) is given by,

Average rate of change = [tex]\frac{f(b)-f(a)}{b-a}[/tex]

Following this rule,

Average rate of change in the interval (2, 4)

= [tex]\frac{C(4)-C(2)}{4-2}[/tex]

= [tex]\frac{490.8-472.2}{4-2}[/tex]

= 9.3

Average rate of change in the interval (46, 48)

= [tex]\frac{-10.8-49.8}{2}[/tex]

= -30.3

Average rate of change in the interval (12, 14)

= [tex]\frac{529.8-529.2}{2}[/tex]

= 0.3

Average rate of change in the interval (22, 24)

= [tex]\frac{478.8-496.2}{24-22}[/tex]

= --8.7

Average rate of change is greatest in the interval (2, 4)

Option (A) will be the answer.

Answer:

Average rate of change is greatest in the interval (46. 48)

Step-by-step explanation:

Average rate of change in the interval (2, 4)

= 9.3

Average rate of change in the interval (46, 48)

= -30.3

Average rate of change in the interval (12, 14)

= 0.3

Average rate of change in the interval (22, 24)

= --8.7

Answer:

C x=12

Step-by-step explanation:

x - 17 = -5        add seventeen to both sides

x = 12

Answer:

c

Step-by-step explanation:

Using translation concepts, it is found that the point (0, 0) on the graph of f(x) corresponds to point (7, 9) on g(x).

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.

here, we have,

Considering the translations, the equivalent point is found as follows:

x -7 = 0 -> x =7.

y = 0 +9-> y = 9.

Hence the point (0, 0) on the graph of f(x) corresponds to point (7,9) on g(x).

Answer:

im dumb im sorry but u can look it up

Step-by-step explanation:

Answer:

x= -1/5

Step-by-step explanation:

1

Add 9x9x to both sides.

x+9x=-2x+9x=−2

2

Simplify  x+9xx+9x  to  10x10x.

10x=-210x=−2

3

Divide both sides by 1010.

x=-\frac{2}{10}x=−102

4

Simplify  \frac{2}{10}102  to  \frac{1}{5}51.

x=-\frac{1}{5}x=−51

Thank you for the extra points

Answer:

2. x=25°

3. x=15°

4. x=26°

Step-by-step explanation:

For problem 2, we know the sum of the angles of a triangle is 180°. Also, supplementary angles are 180°.

30+20+x=180                  [combine like terms]

50+x=180                         [subtract both sides by 50]

x=130

Now that we have the missing angle, we can use that to solve for x.

2x+130=180                     [subtract both sides by 130]

2x=50                               [divide both sides by 2]

x=25°

Now, we know that x=25°.

For problem 3, we know the sum of the angles of a triangle is 180°. This means, we add all the angles together and get 180°.

8x+25+2x+5=180            [combine like terms]

10x+30=180                     [subtract both sides by 30]

10x=150                            [divide both sides by 10]

x=15°

Now, we know that x=15°.

For problem 4, we know the sum of the angles of a triangle is 180°. This means, we add all the angles together and get 180°.

x+12+52+90=180             [combine like terms]

x+154=180                        [subtract both sides by 154]

x=26°

Now, we know that x=26°.

Answer:

3. x = 5        4. x = 26

Step-by-step explanation:

3.

(2x + 5)  + 8x + 25 = 180

10x +30 = 180

10x = 150

x = 15

4.

52 + 90 + x+12 = 180

52 + 90 + 12 = 142

x + 142 = 180

x = 180 - 154

x = 26
