    -4-2= -6
   =(x-4)(x-2)

3. the answer is A
    if you plug in the points into the equation y=x
    y= 1/2x + 4
given point: (4,6) x=4 y=6

Plot the intercepts to graph the equation. x+y=3
andrey2020 [161]

Answer:  You will have points plotted at +3 on the y axis, and +3 on the x axis.

The attachment shows what your graph should look like.

Step-by-step explanation:

The intercept is where the graphed line crosses an axis.

To find the y-intercept, substitute 0 for x and solve for y:

0 + y = 3.  Subtracting 0, you have y = 3

So you can plot a point at +3 on the y axis.

To find the x- intercept, substitute 0 for y, and solve for x

x + 0 = 3  Again, subtracting 0, x = 3

So plot a point on the x-axis at +3

Use the line tool to connect the two points.

Genelle is paid $1,122.38 semimonthly. What is her average monthly net or take home pay ?
sveta [45]

Answer: $2244.76

Step-by-step explanation:

Well, <em>semimonthly </em>means that she is paid the amount of $1,122.38 twice a month. I am making the assumption that taxes have already been taken out of this amount, and the amount listed above is how much she will take home. I then multiplied $1,122.38 × 2 which equaled $2244.76. This is how much Genelle will take home monthly.
