Answer:

Step-by-step explanation:

AB + BC = AC

14 + 3x-4 = 4x+4

Combine like terms

10 +3x = 4x+4

Subtract 3x from each side

10+3x-3x = 4x+4-3x

10 = x+4

Subtract 4 from each side

10-4 =x-4+4

6 =x

We want AC

AC = 4x+4 = 4*6+4 = 24+4 = 28

Let's see

AB+BC=AC14+3x-4=4x+43x+10=4x+410-4=4x-3xx=6

18. Mabel gave Margo a bag containing red, white, and
blue marbles. The bag contained half as many red
marbles as blue ones, and 1/4 of the marbles in the
bag were white. If 8 of the marbles were red, how
many marbles were in the bag?

Answers

So if the bag contains half as many red marbles as blue ones, and there are 8 reds then there are 16 blues. 16 + 8= 24 if you want there to be 1/4 white marbles add 6. 6/30 is 1/4.

So the answer comes out to be 30 marbles in the bag

Answer:

32.

Step-by-step explanation:

Let the number of red marbles be x then the number of blue = 2x

So we have 8 red and 16 blue marbles.

If the total number of marbles are y marbles the number of white one = y/4.

So  y = y/4 + 8 + 16

3/4y = 24

y = 24 * 4/3

= 96/3

= 32 marbles.

What is the value of the expression?

When the relevant factors and natural laws of a mathematical model are given values, the outcome of the calculation it describes is the expression's outcome.

The quadratic expression is given below.

⇒ 5x² - 11x + 18

The value of the expression at x = 2.4, then the value of the expression will be

⇒ 5(2.4)² - 11(2.4) + 18

⇒ 28.8 - 26.4 + 18

⇒ 20.4

The value of the expression at x = -3, then the value of the expression will be

⇒ 5(-3)² - 11(-3) + 18

⇒ 45 + 33 + 18

⇒ 96

The value of 5x² - 11x + 18 is when x = 2.4 and when x = -3 will be 20.4 and 96.

Use the graph of f to find F(2).

A. 0.5
B. Does not exist
C. -8
D. -0.5

Answers

Hey there! Before we start with the problem, you mean f(2) instead of F(2) if I'm correct. In maths, variables are case-sentitive so F and f both are different.

First, f(2) means the value of y at x = 2.

f(2) is when we substitute x = 2 in and receive the output (y-value).

In coordinate plane, we have (x,y) as a point. What we have to do is to look at the graph, you will see the point that contains (2,-8)

That's it! Refer above, f(2) is when we substitute x = 2 and get y-value.

Hence, f(2) = -8

Find the mean, median, and mode of 14, 15, 3, 15, 14, 14, 18, 15, 8, 16.

Answers

Answer:

mean: 13.2 (average)

median: 14.5 (Center)

mode: 14 and 15 (because data is bimodal so there are two modes

Step-by-step explanation:

Answer:

mean = 13.2, median = 15.5, mode = 18

Step-by-step explanation:

mean = 14+15+3+15+14+14+18+15+8+16/10

= 132/10 = 13.2

median =[ (n/2)th term + (n/2+1)term ]/2

here n is even so this formula is applied and before this is done, the numbers given are to be arranged in ascending or descending order

= [10/2 + (10/2+1)]/2

= [5th term + 6th term]/2

= (15+16)/2

= 31/2 = 15.5

mode = 18

please answer this question I have for you now

Answers

Answer:

A. 10

Brainliest, please!

Step-by-step explanation:

(1, 2)(x, 5) = 1/3

5 - 2 / x - 1 = 1/3

3 / x - 1 = 1/3

x - 1 = 3 / 1/3

x - 1 = 9

x = 9 + 1

x = 10

Perpendicular lines have gradients that multiply to make -1. In this case 1/3 x -3 = -1
(5 - 2)/(x - 1) = -3
3 / (x - 1) = -3
So (x - 1) = -1
x = 0

Given the linear function f(x)= - 5/8x + 16, does the point (1,2) lie on the line?

Answers

No, it doesn’t lie on the line.

For a point to lie on the line, you have to be able to plug the x coordinate into the x and the y coordinate into f(x) and the math has to be true. In this case, plug in the x and y and you get 2=-5/8(1) + 16
Simplify the math and the two sides are not equal, therefore that point does not lie on the line. Points that lie on the line are solutions that make the equation true.
