Answer:

A. 6

Step-by-step explanation:

10x \degree + 30 \degree = 90 \degree \\(complementary \:angles) \\\\ 10x \degree  = 90 \degree  - 30 \degree\\  \\ 10x \degree  = 60 \degree  \\  \\ 10x = 60 \\  \\ x =  \frac{60}{10}  \\  \\ x = 6

There are 2 red, 3 blue, and 4 green marbles in a jar?<br><br> What does the ratio 4 to 9 represent?
MrMuchimi

Hello!

How many marbles are in the jar all together?

3 + 2 + 4 = 9

We also know that there are 4 green marbles in the job.

So, I would assume that the answer is;

Green Marbles : Total Marbles or Green Marbles to Total Marbles.

10x-2y=18 8x=y solve by substitution
lana [24]

Answer:

x = -1 and y = 18

Step-by-step explanation:

Given the system of equations

y + 8x = 10... 1

2y - 4x = 40 ... 2

From 1; y = 10-8x

Substitute into 2;

2(10-8x) - 4x = 40

20 - 16x - 4x = 40

20 - 20x = 40

-20x = 40 - 20

-20x = 20

x = -1

Recall that y = 10-8x

y = 10 - 8(-1)

y = 10 + 8

y = 18

therefore your answer is  x = -1 and y = 18

Michele wanted to measure the height of her school’s flagpole. She placed a mirror on the ground 48 feet from the flagpole, then
zepelin [54]
Refer to the diagram below for the sketch of the position of the mirror, Michelle, and the flagpole.

Using similar triangle concept, to find the height of the flagpole, we first need to find out the scale factor of the horizontal distance. 
We write this as ratio
Mirror to Michelle : Mirror to Flagpole
            12ft             :             48ft
             1                :               4

So the ratio of the height is
Michelle : Flagpole
     1         :       4
    5ft       :      20ft

Answer: A

A 2-column table with 6 rows. The first column is labeled x with entries negative 3, negative 2, negative 1, 0, 1, 2. The second
ikadub [295]

The largest interval of x-values where the function is increasing is (-1, 1)

<h3>How to determine the largest increasing interval?</h3>

The table of values is added as an attachment

From the table, the function f(x) decreases from x = -3 to x = -1 and x = 1 and x = 2

So, we make use of the intervals

x = -1, 0 and 1

From the table,

From x = -1 to 0, the change is 3

From x =  0 to 1, the change is 3

From x =  -1 to 1, the change is 6

Using the above highlights, the largest increasing interval is (-1, 1)

Hence, the largest interval of x-values where the function is increasing is (-1, 1)
