What is 2,200x in scientific notation?

1 answer:

5 0

Answer: 2.2x * 10^3
You would have to move the decimal place 3 times for 2.2x to get 2,200x, thus you get 10^3.

Hope this helps!

Answer: $f(-735) = -\frac{2}{3}(-735) + 490 = 980$

Step-by-step explanation:

$f(x) = -\frac{2}{3} x + 490 =0$ Subtract 490 from both sides

$\frac{3}{2}* -\frac{2}{3} x = -490 *\frac{3}{2}$ Then flip $-\frac{2}{3}$ multiply both sides by $\frac{3}{2}$ to cancel out $-\frac{2}{3}$

$x= -735$ Thus giving you -735 as your $x$ .

Then you plug it back into the equation to solve.

Y+1=3(x – 4)<br> 2-intercept:<br> C<br> y-intercept:

kiruha [24]

Answer:

x-intercept is (13/3, 0)

y-intercept is (0,-13)

Step-by-step explanation:

change y+1 = 3(x-4) into slope-intercept form:

y+1 = 3x-12

y = 3x-13

y-intercept is (0,-13)

to get x-intercept, plug zero in for 'y' and solve for 'x':

0 = 3x-13

13 = 3x

13/3 = x

x-intercept is (13/3, 0)

Carl collects coins compulsively, but he only likes quarters and dimes. Carl currently has 125 coins for a total of $26.00. How

faust18 [17]

We need to find the two equations that represents the total amount of coins Carl has that makes $26.00 and the number of quarters and dimes.

Carl has 35 dimes and 90 quarters. The equations are $0.1x+0.25y=26$ and $x+y=125$ .

Let the number of dimes be $x$

Let the number of quarters be $y$

The total number of coins is $125$

So, the first equation will be

$x+y=125$

The value of the coins is $26. So,

$0.1x+0.25y=26$

Let us solve the equations

$x=125-y$

$0.1\times (125-y)+0.25y=26\\\Rightarrow 12.5-0.1y+0.25y=26\\\Rightarrow 0.15y=13.5\\\Rightarrow y=\dfrac{13.5}{0.15}\\\Rightarrow y=90$

$x+y=125\\\Rightarrow x=125-90\\\Rightarrow x=35$

The number of dimes is 35 and the number of quarters is 90.

Step-by-step explanation:

she has 3.85 miles left to go because she already ran 1.45 and if you subtract that from the 5.3 you get 3.85 left to run.
