Answer:

We conclude that:

f(g(3)) = 2

Hence, option B is correct.

Step-by-step explanation:

Given the f(x) table

x         2          3            4          5

f(x)      0           1             2         3

Given the g(x) table

x         1           2           3            4

g(x)      1           2            4           8

We need to determine f(g(3)).

In order to determine f(g(3)), first, we need to determine g(3)

It is clear from the table of g(x),

at x = 3, g(3) = 4

so

f(g(3)) = f(4)

Now, we need to check the value of f(4) at x = 4 using the table f(x)

It is clear from the table of f(x),

at x = 4, f(4) = 2

Thus,

f(g(3)) = f(4) = 2

Therefore, we conclude that:

f(g(3)) = 2

Hence, option B is correct.

C)
y =1/2x + 5/2

Answers

Answer:

D

Step-by-step explanation:

y_2 - y_1 / x_2 - x _1

4 - 2 / 3 - (-1) = 2/4 = 1/2

y +4 = 1/2 (x + 3) distributive property

y + 4 = 1/2x + 1.5

y= 1/2x - 5/2 subtraction (you subtract 4 from both sides) (-5/2 = -2.5)

therefore your equation is y = 1/2x - 5/2

Which expression is equivalent to (-5/6) / (10/3)?

Answers

Answer:

[tex]\frac{\left(-\frac{5}{6}\right)}{\left(\frac{10}{3}\right)}=-\frac{1}{4}[/tex]

Step-by-step explanation:

Given the expression

[tex]\frac{\left(-\frac{5}{6}\right)}{\left(\frac{10}{3}\right)}[/tex]

Let us solve the expression

[tex]\frac{\left(-\frac{5}{6}\right)}{\left(\frac{10}{3}\right)}=\frac{-\frac{5}{6}}{\frac{10}{3}}[/tex]

Apply fraction rule:  [tex]\frac{-a}{b}=-\frac{a}{b}[/tex]

         [tex]=-\frac{\frac{5}{6}}{\frac{10}{3}}[/tex]

Divide fractions:  [tex]\frac{\frac{a}{b}}{\frac{c}{d}}=\frac{a\cdot \:d}{b\cdot \:c}[/tex]

         [tex]=-\frac{5\cdot \:3}{6\cdot \:10}[/tex]

Multiply the numbers: [tex]6\cdot \:10=60[/tex]

         [tex]=-\frac{5\cdot \:3}{60}[/tex]

Multiply the numbers:  [tex]5\cdot \:3=15[/tex]

         [tex]=-\frac{15}{60}[/tex]

Cancel the common factor:  15

         [tex]=-\frac{1}{4}[/tex]

Therefore, we conclude that the equivalent expression is:

[tex]\frac{\left(-\frac{5}{6}\right)}{\left(\frac{10}{3}\right)}=-\frac{1}{4}[/tex]

(25-a) divided by 7=3

Answers

Answer:

a = -0.57

rounded to the nearest tenth: a = -0.6

Step-by-step explanation:

(25 - a) ÷ 7 = 3

25 - a ÷ 7 = 3

25 ÷ 7 - a = 3

3.6 - a = 3

3.57 - 3.57 - a = 3 - 3.57

a = -0.57

The value of "a" in the equation (25 - a) ÷ 7 = 3 is 4.

To find the value of "a" in the equation (25 - a) ÷ 7 = 3.

we can solve for "a" by isolating it on one side of the equation.

(25 - a)/7 = 3.

Multiply both sides of the equation by 7 to get rid of the division:

7(25 - a)/7 = 3 × 7.

25 - a = 21.

To isolate "a," subtract 25 from both sides of the equation:

25 - a - 25 = 21 - 25.

Simplifying further, we get:

-a = -4.

Multiply both sides of the equation by -1 to solve for "a":

-1 × (-a) = -1× (-4).

a = 4.

Therefore, the value of "a" in the equation (25 - a) ÷ 7 = 3 is 4.
