Answer:

[tex]\huge\boxed{x=9}[/tex]

Step-by-step explanation:

We know that ∠A and ∠B are the same exact length. Since one of the angles is given to us in an exact length, we can set the measures equal to each other.

[tex]4x + 9 = 45[/tex]

Let’s solve for x.

[tex]4x +9-9=45-9\\\\4x=36\\\\x=9[/tex]

Answer:

Original number of sixes = 6

Original number of nines = 10

Step-by-step explanation:

We are told in the question that:

A certain number of sixes and nines is added to give a sum of 126

Let us represent originally

the number of sixes = a

the number of nines = b

Hence:

6 × a + 9 × b = 126

6a + 9b = 126.....Equation 1

If the number of sixes and nines is interchanged, the new sum is 114.

For this second part, because it is interchanged,

Let us represent

the number of sixes = b

the number of nines = a

6 × b + 9 × a = 114

6b + 9a = 114.......Equation 2

9a + 6b = 114 .......Equation 2

6a + 9b = 126.....Equation 1

9a + 6b = 114 .......Equation 2

We solve using Elimination method

Multiply Equation 1 by the coefficient of a in Equation 2

Multiply Equation 2 by the coefficient of a in Equation 1

6a + 9b = 126.....Equation 1 × 9

9a + 6b = 114 .......Equation 2 × 6

54a + 81b = 1134 ........ Equation 3

54a + 36b = 684.........Equation 4

Subtract Equation 4 from Equation 3

= 45b = 450

divide both sides by b

45b/45 = 450/45

b = 10

Therefore, since the original the number of nines = b,

Original number of nines = 10

Also, to find the original number of sixes = a

We substitute 10 for b in Equation 1

6a + 9b = 126.....Equation 1

6a + 9 × 10 = 126

6a + 90 = 126

6a = 126 - 90

6a = 36

a = 36/6

a = 6

Therefore, the original number of sixes is 6

Answer:

132

Step-by-step explanation:

3 = 1/44x

÷1/44. - 1/44

= 132. = x

Answer:

x = 132

Step-by-step explanation:

3 = (1/44)x

3/(1/44) = (1/44)x/(1/44)

132 = x

Answer:

[tex]f(x) = \frac{2x}{2x + 3}[/tex]

Step-by-step explanation:

Given

[tex]h(x) = \frac{2x + 3}{x}[/tex]

[tex]g(x) = \frac{2}{x}[/tex]

[tex]g(f(x)) = h(x)[/tex]

Required

Find f(x)

[tex]g(x) = \frac{2}{x}[/tex]

Substitute x for f(x)

[tex]g(f(x)) = \frac{2}{f(x)}[/tex]

Recall that

[tex]g(f(x)) = h(x)[/tex]

This gives

[tex]\frac{2}{f(x)} = \frac{2x + 3}{x}[/tex]

Cross Multiply

[tex]f(x) * (2x + 3) = 2 * x[/tex]

[tex]f(x) * (2x + 3) = 2 x[/tex]

Make f(x) the subject of formula

[tex]f(x) = \frac{2x}{2x + 3}[/tex]

Step-by-step explanation:

The first oval is the domain and the second oval is the range.

Answer:

x=6 and x=12 are parallel.

Step-by-step explanation:

If you graph x=6 it will be a straight verticle line on the x-axis where 6 is, same with x=12 (put a vertical line on 12 for the x-axis). When you put these both on the same graph you see they are directly across from each other but will never touch. Therefore, they are parallel. If you are writing this on paper, simply draw a graph to show this.

Answer:

0.5 or -0.5

Step-by-step explanation:

4x - 3 = 3x - 1

-1 + 3 = 2

4x = 3x - 2

4 - 3 = 1

1x = -2 or positive 2

1x ÷ -2

-0.5 or 0.5

-----‐------------------------

4x-3 = 1

3x -1 = 0.5

f= 1

g= 0.5

1 x 0.5 = x

x= 0.5

The required value for which h(x) = 18 is given as x = 7.

Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.

Here,
The function h(x) = 2x + 4 - - - - (1)

Since h(x) =18

Substitute h(x) = 18 in equation 1,
18 = 2x + 4

Simplify
18 - 4 = 2x
x = 14 / 2
x = 7

Thus, the required value for which h(x) = 18 is given as x = 7.

Step-by-step explanation:

The contrapositive is formed by negating both statements and swapping them, as here.

Answer:

C

Step-by-step explanation:

58*24=1392, which is closest to 1200.

Or, you could round the numbers to the nearest tens place, which would give you 60*20, giving you the exact answer of 1200. I think this was the preferred way of solving it.

Answer:

450

Step-by-step explanation:

The idea is to use the tangent line to [tex]f(x)=\sqrt x[/tex] at [tex]x=25[/tex] in order to approximate [tex]f(25.3)=\sqrt{25.3}[/tex].

We have

[tex]f(x)=\sqrt x\implies f(25)=\sqrt{25}=5[/tex]

[tex]f'(x)=\dfrac1{2\sqrt x}\implies f'(25)=\dfrac1{10}[/tex]

so the linear approximation to [tex]f(x)[/tex] is

[tex]L(x)=f(5)+f'(5)(x-5)=5+\dfrac{x-5}{10}=\dfrac x{10}+\dfrac92[/tex]

Hence [tex]m=\frac1{10}[/tex] and [tex]b=\frac92[/tex].

Then

[tex]f(25.3)\approx L(25.3)=\dfrac{25.3}{10}+\dfrac92=\boxed{7.03}[/tex]
