6k-4m

Combine like terms, 4k + k + k= 6k.
You cannot combine 4m and 6k because they are not like terms. You are left with 6k - 4m

Can someone explain how to do this - 3/4 divided by 1/4
svetoff [14.1K]

(you flip 1/4 and it went a moltiplication and semplify 4 with 4 (4:4=1), multiply -3 * 1 = -3

-3/4 : 1/4 =

-3/4 * 4/1 =

-3 * 1 =

On the ceiling of a cavern, a stalactite grows downward
Tcecarenko [31]
The stalactites become 0.004 + 0.006 = 0.01 inches closer each year, and begin 10 feet apart, or 120 inches apart. 

let y be the distance between them, and x be the number of years that go by:
y = -0.01x + 120

We want to find where y = 0, where they meet:
0 = -0.01x + 120        Add 0.01x to both sides
0.01x = 120               Multiply both sides by 100
x = 12,000 

The stalagmite and stalactite will meet in 12,000 years

Acellus help slope intercept
Serjik [45]

Greetings.

The answer is y = 2x + 7.

Explanation:

If you are an expert in graph then you are able to find the slope without calculating. (Rise over Run by looking at the graph.)

We can also find the slope by calculating m-value.

m=\frac{y_2-y_1}{x_2-x_1}   ---> Rise Over Run

<em>But how are we gonna calculate if we don't have any two given ordered pairs?</em>

The answer is, we can just pick two ordered pairs that are part of the graph, or rather say that the graph passes through.

The graph passes through (-3,1) and (-2,3).

Then we can calculate the slope by using rise/run.

m=\frac{3-1}{-2-(-3)}\\m=\frac{2}{-2+3}\\m=\frac{2}{1}\\m=2

Thus, the slope is m = 2.

However, we are not done yet. We just only found out the slope. We need to find the y-intercept too.

From Linear Function - y=mx+b

Where m = slope and b = y-intercept.

Since b = y-intercept, we don't need to calculate/substitute x = 0. We simply find which number the graph has y-intercept at.

Which is (0,7), the y-intercept.

Then we substitute b = 7 as y-intercept.

Thus the answer is y=2x+7

Anthony writes a numerical expression 2+10x3-2 and says that the expression has a value of 34. Is Anthony correct? Explain your
lapo4ka [179]

Answer:

Anthony is incorrect

According to the order of operations(PEMDAS), you must first multiply 10 × 3

which equals 30, then you add 2, which equals 32, finally you subtract 2, which brings you back to 30

10 × 3 = 30

2 + 30 - 2 = 30
