f(x) =2x-4 and g(x) =-3x+2 find: f(g(x))

Answers

Answer:

[tex]f(g(x))=-6x[/tex]

Step-by-step explanation:

Composite Function

Given f(x) and g(x) as real functions, the composite function named [tex](f\circ g)(x)[/tex] is defined as:

[tex](f\circ g)(x)=f(g(x))[/tex]

It can simply be found by substituting g into f.

Our functions are:

[tex]f(x)=2x-4[/tex]

[tex]g(x)=-3x+2[/tex]

Substituting g into f:

[tex]f(g(x))=2(-3x+2)-4[/tex]

Operating:

[tex]f(g(x))=-6x+4-4[/tex]

Simplifying:

[tex]\boxed{f(g(x))=-6x}[/tex]

10 times the sum of half a number x and 4 is 6

Answers

Answer:

-10.4

Step-by-step explanation:

Assume that the number we are looking for is x.

Now, we want to get 10 times the sum of half the number and 6 and equate this expression to 8. Then we can solve for x

step by step

half the number is 0.5x

the sum of half the number and 6 is 0.5x + 6

10 times the sum of half the number and 6 is 10(0.5x +6)

10 times the sum of half the number and 6 equals 8 is 10(0.5x+6) = 8

Now solve for x

10(0.5x + 6) = 8

5x + 60 = 8

5x = 8 - 60

5x = -52

x = -52/5

x = -10.4

Is number 1 = 90 ?

Answers

Yes you are correct. The diagonals of any kite are perpendicular.

This can be proven by showing that triangle KGH is congruent to triangle KJH through the SSS congruence theorem. From there you break up the triangles focusing on triangle JRK and triangle GRK, now using the SAS rule to conclude that angle JRK = angle GRK. Since those are a linear pair, those angles must be right angles.

Side note: A kite is defined to be any quadrilateral in which it has two pairs of adjacent congruent sides. Not all four sides are the same length though (otherwise we would have a rhombus).

D) 5/6 as 5/6 = 0.833333333333333 and the three will keep repeating

Answer:

D.

Step-by-step explanation:

You meant which one is a repeating decimal.

Okay to find out you would have to divide each.

4 divided by 5 = 0.8

1 divided by 2 = 0.5

3 divided by 4 = 0.75

5 divided by 6 = 0.833333333...

See how the three keeps on repeating? That makes it a repeating decimal.

5-y=-3x in standard form

Answers

Answer:

y = 3x + 5

Step-by-step explanation:

The linear formula follows this general form: y = mx + c

Hence, to put 5-y=-3x in standard form, you would rearrange it

-y = -3x - 5

y = 3x + 5

Answer:

3x-y=-5

Step-by-step explanation:

standard form is Ax + By = C

5-y=-3x      move the y to the other side by adding it to the -3x

-3x+y=5     The x cant be negative so switch all the signs

3x-y=-5

What is an equation that goes through (12, 5); m = -3
Please help

Answers

Answer:

Step-by-step explanation:

Use this formula:

y - y1 = m ( x - x1 )

We are told m = -3 and given the point (12 , 5) ---- > so x1 = 12 and y1= 5

Put these values into the formula above and you get:

y - y1 = m ( x - x1 )

y - 5 = -3 ( x - 12 )

y - 5 = -3x + 36

y = -3x + 36 + 5

y = -3x + 41

Part A
Joseph runs 2 miles on Monday. Each day after that, he runs the same 1 mile route every morning. His goal is to run at least 6 miles
by the end of the week. Which inequality represents the least number of days after Monday that Joseph needs to run to reach his goal?

Answers

Sine he runs 2 miles on Monday, we already have a +2.

Then, he runs by a constant rate of 1, which is the constant rate of change per day.

Let x represent the number of days he runs and y the total amount of miles he runs. Now, the equation is y = x + 2

However, he needs to run at least 6 miles. At least means greater than or equal to. The values for y can be greater than 6, or equal to 6.

y ≥ 6

y = x + 2

Now substitute x + 2 for y.

x + 2 ≥ 6

Subtract 2.

x ≥ 4

This is the inequality. He has to run for at least 4 days.
