The answer would be H, because it is rotating 90 degrees which would end up on Quadrant l (+, +).

Add the two expressions.<br><br> −2.4n−3 and −7.8n+2
Sphinxa [80]

Answer:

-10.2n - 1

Step-by-step explanation:

We have two expressions in variable n and we have to add the two expressions.

An important thing to note is that only like terms can be added. i.e. the term with "n" can only be added or subtracted to the term with "n". Similarly a constant can only be added or subtracted to a constant.

(-2.4n-3)+(-7.8n+2)\\=-2.4n-3-7.8n+2\\=-2.4n-7.8n-3+2\\=-10.2n-1

Thus, the two given expressions add up to -10.2n - 1

I need help on this one
bulgar [2K]

Answer:

16 months

Step-by-step explanation:

Look at the chart on the left and look at what number of months is closest to 15,000. 16 is at 15,034

To solve mathematically:

y is the balance that his account would have. You want to find the amount of months it will take before it becomes $15,000, so 15000 is your y value

15,000= - 440.91x+22,060.7

-7,060.7= - 440.91x    Subtract 22,060.7 from both sides

16.0139=x   Divide both sides by - 440.91

frutty [35]

Answer:75

Step-by-step explanation:First isolate x by getting rid of the 100 so the equation becomes 3x=x +150 then you subtract x From both sides so it’s 2x=150 then divide by two on both sides so you get X = 75
