PLEASE HELP ME this is really hard please

Answer:

  1100

  2200

Step-by-step explanation:

Since speed is constant, the distance is proportional to the time. We notice that the number in the second column is 1650/3 = 550 times the number in the first column, so the two missing numbers are ...

  2 × 550 = 1100

  4 × 550 = 2200

Answer:

1 \frac{7}{12}  \: or \: 1.583

Step-by-step explanation:

nine fourths is also

\frac{9}{4}

two thirds is also

\frac{2}{3}

subtract,

\frac{9}{4}  -  \frac{2}{3}

L.C.M = 12

\frac{27 - 8}{12}

\frac{19}{12}

1  \frac{7}{12}  \: or \: 1.583

Graph y equals 1/2 x - 3​
Elis [28]

Answer:

Resulting plot in the image attached

Step-by-step explanation:

Start by making a table of (x,y) pairs that satisfy this equation. Notice that two pairs would be enough, but it is always safer to obtain at least three to see them actually "aligned".

We are trying to find values for y when x= 0, 2, and 4 to make our calculations simple:

y=\frac{1}{2} x-3

When x = 0 then: y=\frac{1}{2} (0)-3=-3 So we plot the value (0,-3) on the x-y plane.

When x = 2 then: y=\frac{1}{2} (2)-3=1-3=-2 So we plot the value (2,-2) on the x-y plane.

When x = 0 then: y=\frac{1}{2} (4)-3=2-3=-1 So we plot the value (4,-1) on the x-y plane.

Please see the points and the resulting line in the image attached

Irrational numbers are numbers with infinite decimals values that are not repeating (ex. Pi 3.14159265....). Whole numbers don’t have decimal values in the first place, so all whole numbers are therefore rational.

Keep in mind that just because a number has decimal values doesn’t mean it’s irrational (ex. 4.5 is a rational number). It needs to have infinite non-repeating decimal values to be irrational.
