Solve by inspection: X+4=15

Mathematics

x + 4 = 15

- 4        -4

x = 11

You would subtract 4 because you need to isolate the x to get the value of x. You would subtract it to both sides because whatever you do on one side, you have to do it to the other side.

Explanation:

x+4=15

subtract by 4 both sides of an equation.

x+4-4=15-4

then simplify.

15-4=11

<u><em>x=11 is the final answer.</em></u>

Hope this helps!

Thanks!

Have a great day!

Graph the system of inequalities to show all possible solutions.<br> {y&lt;3x-2<br> {y ≥ -x+3
Semmy [17]

Answer:

see attachment for graph

Step-by-step explanation:

< or > : dashed line

≤ or ≥ : solid line

< or ≤ : shade below the line

> or ≥ : shade above the line

<u>To graph the line y < 3x-2</u>

Rewrite the equation as: y = 3x - 2

Find two points on the line:

when x = 0,  y = 3(0) - 2 = -2  →  (0, -2)

when x = 3,  y = 3(3) - 2 = 7  →  (3, 7)

Plots the found points (0, -2) and (3, 7).

Draw a straight, dashed line through the points.

<u>To graph the line y ≥ -x + 3</u>

Rewrite the equation as: y = -x + 3

Find two points on the line:

when x = 0,  y = -(0) + 3 = 3  →  (0, 3)

when x = 3,  y = -(3) + 3 = 0  →  (3, 0)

Plots the found points (0, 3) and (3, 0).

Draw a straight, solid line through the points.

Shade above the solid line and below the dashed line to the right of where the two lines intersect.  <u>The shaded area is the area of all possible solutions</u>.

Enter the equation in the form of y=mx+b
soldi70 [24.7K]

Answer:

y=-3/4x+2

Step-by-step explanation:

The b in 'y=mx+b' is 2 because thats where the line crosses on the y-axis. When finding the slope which is m in this situation keep in mind, rise over run. Now obviously this line is descending so we have to count down to where the next solid point is. In this case we count down to 3. Then we run or go over to the point which is 4 spaces over. Since our line is descending its a negative.

Hence, y=-3/4+2

Hope this helps (:
