Y=6x – 11 -2x – 3y =-7

Mathematics
1 answer:
Eva8 [605]4 years ago
4 0

Answer:

x=2   and   y=1

Step-by-step explanation:

1). Plug the y value into the second equation. It will look like the following afte you plug in what y equals:

              -2x-3(6x-11)=-7

2). Then, you distribute the "-3" to all the terms inside the parenthesis.

              -2x-18x+33=7

3). Then, you subtract the positive 33 from both sides to try to get the x alone on one side.

              -2x-18x=-40

4.) Then, you combine all of the terms containing an x.

              -20x=-40

5). Finally, you divide both sides by -20 and the outcome is x=2.

6).  Hold up...we ain't done yet..

7).  Next, you have to plug the x back into the either equation to get the outcome of what y will be, but for this purpose I will plug it back into the first equation.

              y=6(2)-11

8). I will then distribute the 6 into the all the terms in the parenthesis and then it will look like this.

              y= 12-11

9). Do the math...and the answer is y=1.

8t-9 is less than or equal to 79
sattari [20]

Answer:

t ≤ 11 (or all values 11 or less)

Step-by-step explanation:

8t - 9 ≤ 79

<em>So, I am assuming you are trying to find the value(s) of "t".</em>

Add 9 to both sides.

8t ≤ 88

Divide 8 by both sides.

t ≤ 11

The initial count of a certain type of bacteria in a culture is 350. If the bacteria grows at the rate of 20% per hour, which fu
raketka [301]
I think it is 350(1.2)^t because you take the starting amount (350) and then multiple it by the growth rate (which is 20%, but when added to 100 and the put into a decimal is 1.2) raised by the number of hours (t).
I hope this helps.

A full rotation is 360 degrees, if the fan moves 75 degrees (360-75) the fan will have a total of 285 degrees left too rotate in order to make a single, full rotation.

39an angle measures 76° less than the measure of a complementary angle. what is the measure of each angle?
torisob [31]

Answer:

14 ° and 76 °

Step-by-step explanation:

We have that two angles are complementary, if the sum of their amplitudes is 90 °.

The complementary angles need not be consecutive or have any point in common.

Alpha and Beta are complementary if:

Alpha + Beta = 90 °

In this case it would be:

X - 76 ° = 90 °

X = 90 ° - 76 °

X = 14 °

Which means that each angle measures 14 ° and 76 °
