I need help with this plzzzz it's difficult?

Answer:

Option 3

Step-by-step explanation:

Option 1

f(a) = a² - 4

g(a) = √a

(gof)(a) = [tex]\sqrt{a^{2}-4}[/tex]

Option 2

f(a) = [tex]\frac{1}{2}a-1[/tex]

g(a) = 2a - 2

(gof)(a) = [tex]2[\frac{1}{2}a-1]-2[/tex]

           = (a - 2) - 2

           = a - 4

Option 3

f(a) = 5 + a²

g(a) = [tex]\sqrt{(a-5)}-2[/tex]

(gof)(a) = [tex]\sqrt{(a^2+5-5)}-2[/tex]

           = |a| -2

Option 4

f(a) = 3 - 3a

g(a) = 4a - 5

(gof)(a) = 4(3 - 3a) - 5

            = 12 - 12a - 5

            = 7 - 12a

Therefore, Option 3 is the answer.

Answer:

4 miles

Step-by-step explanation:

2100+150x=2700

2100-2100+150x=2700-2100

150x=600

Divide by 10.

15x=60

x=4

Answer:

12x² - 6; 21 inches ⇒ A

Step-by-step explanation:

Let us solve the question

∵ The side lengths of a triangle are 4x² - 3 in., 4x² - 2 in., 4x² - 1 in.

∴ S1 = 4x² - 3 inches

∴ S2 = 4x² - 2 inches

∴ S3 = 4x² - 1 inches

→ The perimeter of the triangle is the sum of the lengths of its 3 sides

∵ P = S1 + S2 + S3

∴ P = 4x² - 3 + 4x² - 2 + 4x² - 1

→ Add the like terms

∵ P = (4x² + 4x² + 4x²) + (-3 + -2 + -1)

∴ P = 12x² + -6

→ Remember (+)(-) = (-)

∴ P = 12x² - 6

∴ The expression of the perimeter of the Δ is 12x² - 6

∵ x = 1.5

→ Substitute x in the perimeter expression by 1.5

∵ P = 12(1.5)² - 6

∴ P = 12(2.25) - 6

∴ P = 27 - 6

∴ P = 21 inches

∴ The perimeter of the triangle is 21 inches

The expression can be used to find the perimeter of the triangle is 12x² - 6 and its perimeter is 21 inches when x = 1.5

Answer:

its A. 12x2 −6; 21 inches

Answer:

C I believe.

Step-by-step explanation:

Answer:

If we rearrange one of the triangle in different position the two triangles will be similar. And the angle between them will be equal. Therfore the answer is SAS

Answer:

(2,-4)

Step-by-step explanation:

The minimum value is the lowest point on the graph.

Answer:

minimum value = - 4

Step-by-step explanation:

The minimum value is the value of y at the minimum vertex.

The vertex is at (2, - 4 ) with y = - 4

Thus minimum value is y = - 4

Answer:

(-5, -1)

Step-by-step explanation:

Note that a parallelogram is a quadrilateral formed by two pairs of parallel lines.

Notice that to get to (0,1) from (2,7), we must move 2 to the left and 6 down. We can use this to get from (-3, 5) to the missing point.

2 to the left of (-3, 5) is (-5, 5)

6 down from (-5, 5) is (-5, -1)

Therefore, (-5, -1) is our answer.

Answer: x=5

Step-by-step explanation:

2x+22=4(x+3)

First distribute

2x+22=4x+12

Now intractable 2x from both sides

22=2x+12

Now subtract 12 from both sides

10=2x

Now divide by 2 to get x alone

5=x

So

x=5

Answer:

The answer is x = 5, see comments for explanation.

Answer:

-300=j

Step-by-step explanation:

Lets set it up so we can cross multiply.

-60/1=j/-5

-300=j

Hope this helps :3

Answer:

j=300

Step-by-step explanation:

first you move the negative sign to the left so you will get

-60 = -

after multiply both sides 5 so you will get

-60 *5 =-j

after simplify to -60 * 5 to 300 so you will get

-300 = -j

then multiply both sides by -1

then switch the sides and that's how you get your answer .

Step-by-step explanation:

Answer:

y=2/3x+4

Step-by-step explanation:

M is rise over run, so in this graph is 2 rise over 3 run and positive. The y intercept is 4 because x=0 there and that is the y axis.

Answer:

Equivalent expressions

Step-by-step explanation:

Example

Lets start with numbers

1 + 2 = 3

The expression 1 + 2 is equivalent to 3

They have the same value

Now with algebras

2(x + 3) is equivalent i.e also equals to 2x + 6

3(x + 1) - 23 is equivalent to the following expressions:-

3x + 3 - 23

& 3x - 20

In conclusion equivalent expressions are different expressions that have the same values.

Answer:

False. 32.55 rounds to 33

Step-by-step explanation:

If the number after the decimal is larger than 4, then you round up.

Answer:

This isn't true.

Step-by-step explanation:

This isn't true because the fives (5) in 32.55 causes the number to be rounded up to 32. If this doesn't make sense, please message me and I can help you further!

Answer:

7 1/2 x - 3/4 y

Step-by-step explanation:

Answer:

Yes because of the Side-Angle Side postulate

Step-by-step explanation:

It is given that line BC is congruent to line BC

It is given that line AC is congruent to line EC

We now that angle DCE is congruent to angle ACB because they are vertical angles

I'm sorry if this is not the right explanation, but I do believe my answer is correct

Answer:

I believe that there would not be enough information because according to the SAS theorem (side, angle, side) you would need angle measure along with segment lengths to prove congruence, and the stated information does not contain an angle measure.
