20 If f(x) = 15x + 4, find f(x) when x = 2.
A 90
B 21
C 34
D 25

Answers

Answer 1

Answer:

C 34

Step-by-step explanation:

f(x) = 15x + 4      x = 2

f(x) = 15(2) + 4

f(x) = 30 + 4

f(x) = 34

Answer 2

Answer:

Your answer is C. 34

Step-by-step explanation:

Solve f(x) = 15x + 4 where x = 2

f(x) = 15x + 4

Substitute:

f(2) = 15(2) + 4

Multiply:

f(2) = 30 + 4

f(2)= 34

Your answer is C. 34

determine the vertex of y=4(x-25)2+ 91

Answers

Answer:

             (25, 91)

Step-by-step explanation:

y = a(x - h)² + k        ← vertex form of  the equation of the parabola with vertex (h, k)

So y = 4(x - 25)² + 91  means:

a = 4

x - 25 = x - h    ⇒  - 25 = - h  ⇒  h = 25

+ 91 = + k     ⇒    k = 91

Therefore vertex is:

                               (25, 91)

3(2x+5)=3

3 • 2x] + [3 • 5] = 3 

6x + 15 = 3 

6x = –12 

x = –2

2x – 2(3x – 2) = 2(x –2) + 20

2x – 2(3x – 2) = 2(x –2) + 20

2x – 6x + 4 = 2x – 4 + 20 

– 4x + 4 = 2x + 16 

–4x + 4 – 4 –2x = 2x + 16 – 4 -2x

–6x = 12 

x = –2

Step-by-step explanation:

If y=15 when x=5, find y when x=7, given that y varies directly with x.

Answers

Answer:

when x = 7, y = 21

Step-by-step explanation:

This is about direct variation. If y varies directly with x, then there is a constant  factor of variation, k. The constant of variation can be found by ʸ⁄ₓ

k = ʸ⁄ₓ

k = ¹⁵⁄₅ = 3

Now that we have found k, we simply multiply x by it to find y (this is because y is directly proportional to x). We plug in our x = 7 to find y at this point.

y = 3x

y = 3(7)

y = 21

7(x-3)=28 what is the value of x

Answers

Answer:

x=7

Step-by-step explanation:

Distribute the 7

7x-21=28

Add 21 to both sides(because the number is positive)

7x=49

Divide both sides by 7

x=7

Answer:

A and C are correct

Answer:

The slope is negative and it is also proportional (A and C)

Step-by-step explanation:

I used process of elimination.

If you look at the graph you will realize that x is positive and y is negative. Most times this will mean that the slope is negative, since positive and negative = a negative.

You can also tell that the y-intercept is not -3 because the line never intersects at -3 for the y line.

The relationship is proportional it goes through the origin and is also a straight line.

However, for the -6 slope, I can't really see the graph well, so I can't tell what the coordinate points are. If you can tell me, I can edit my answer and help.

the total cost of playing an online game is $170. the base cost of the game is $50, and it costs $30 per month to play the game. The equation 170=30x+50 can be used to find the x (the number of months you play the game). How many months will you get to play the game if the total cost is $170?

Answers

Answer:

x = 4 (4 months)

Step-by-step explanation:

170 = 30x + 50

Step 1: Subtract 50 from both sides

170 - 50 = 30x + 50 - 50

120 = 30x

Step 2: Divide by 30 on both sides

120/30 = 30x/30

x = 4

Step 3: Check

170 = 30(4) + 50

170 = 120 + 50

170 = 170 ✔️
