Are you trying to find x or y? Or if so both.

I will show you how to find both here:

- If you have a graphing calculator, you can press the “y=“ button and put in both of your equations. Then, press Graph and then watch the graph plot the certain points. The two equations will have a point in which they meet. Take this point and that is your answer.

Harrizon [31]

Answer:

  44.2 years

Step-by-step explanation:

If we assume the interest is compounded annually and the investment is a one-time deposit into the account, its value each year is multiplied by 1+6.25% = 1.0625. After n years, the value in the account will be ...

  19000 = 1300·1.0625^n

Dividing by 1300 and taking logs, we have ...

  log(19000/1300) = n·log(1.0625)

  log(190/13)/log(1.0625) = n ≈ 44.24 . . . .  years

It will take about 44.2 years for the account to reach $19,000.

Fill in the missing reason for the last step.

Answer:

Division

Step-by-step explanation:

You divided both sides of the inequality by -3. Multiplying/dividing by negative numbers change the sign of the inequality, so you have ">" turned into "<".

Drag the tiles to the correct boxes to complete the pairs. Not all tiles will be used.
maxonik [38]

Answer:

1) shifts f(x) 4 units down  = g(x) = 2x-10

2) stretches by factor 4    =  g(x) = 8x-24

3) shifts f(x) 4 units right   =  g(x) = 2x-14

4) compresses by factor 4 =  g(x) = 8x-6

Step-by-step explanation:

1)<em> When we have to move the function down by 4 units, subtract the whole function by -4, that is y -4.</em>

Thus, f(x) becomes  g(x) = 2x-6-(4) = 2x-10

2) <em>When the function is stretched away from x axis, it means in Y direction.</em>

<em>  Thus, when stretched 4 units in Y direction, the function becomes 4(f(x))</em>

 =  g(x) = 4(2x-6) = 8x-24

3)<em>When we have to move the function right by 4 units, replace x with (x-4) in the function.</em>

Thus, f(x) becomes  g(x) = 2(x-4)-6 = 2x-8-6 = 2x-14

4) <em>When the function is stretched towards y axis, it means in X direction.</em>

<em>  Thus, when compressed 4 units in X direction, replace the x by 4x.</em>

 =  g(x) = 2(4x)-6 = 8x-6

What is 7500 over 320 in simplest form?
Nina [5.8K]
When writing fractions in simplest form, there are two rules to follow. First, ask if the numerator and denominator can be divided by the same number. Second, see if at least one number in the fraction is a prime number. We do as follows:

7500 / 320 / 20/20 = 375 / 16

a bus travels 48 km in 6 liters of cng gas . how much quantity of cng gas will be needed to go 112 km? ​
makvit [3.9K]

We have:

  • 48 km ---------------- 6 liters of cng gas
  • 112 km ---------------- ? liters of cng gas

So:

\frac{48}{6}  =  \frac{112}{x}

x =  \frac{112 \times 6}{48}  = 14

P/s: x is a quantity of cng gas will be needed to go 112 km.

Answer: 14 liters of cng gas

Ok done. Thank to me :>
