For
|a|=b
assume
a=b and a=-b

|x+7|=12

assume
x+7=12 and x+7=-12
minus 7 both sides
x=5 and x=-19

C is answer

When solving absolute value equations, you must account for both the positive and negative cases.

x+7 = 12       AND        x+7 = -12
x = 5                               x = -19

Answer:

x = -4, y = -4

Step-by-step explanation:

Normally, if it's allowed, I would use a graphing calculator which basically turns the equations (-2x+y=4) and (y=\frac{1}{2}x-2) into two straight lines, which represent the line of possible values that can fit into the equations. However, since you want the value of x and y in both equations to be the same, you have to look for the intersection of the two graphs. I use desmos.com/calculator to just type in the equations and the lines would be drawn automatically. By hovering over the equation, I can get the two values of x and y (the first value is for x, and the second one is for y).

Here is the working if you want to work it out by hand: (I'm using algebra for this one)

-2x+y=4 -------------------------------- Equation 1

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

Substitute Equation 2 into Equation 1:

-2x+\frac{1}{2}x-2=4

Simplify:

-1\frac{1}{2}x-2=4

-1\frac{1}{2}x=4+2

-1\frac{1}{2}x=6

1\frac{1}{2}x=-6

\frac{3}{2}x=-6

3x=-6×2

3x=-12

x=-12÷3

x=-4 ------------------------------------ Equation 3

Substitute Equation 3 into Equation 1:

-2(-4)+y=4

Simplify:

8+y=4

y=4-8

y=-4

Thus, x=-4, y=-4

Mario draws a scale drawing that includes a ladybug. The actual ladybug is 8 millimeters long. The ladybug in Mario's drawing is
solniwko [45]
Scale factor shows by how much the original model has been multiplied or divided by to get the measurements of the drawing .
In this case the ladybug is 8 mm long but drawing length is 2 cm.
Let’s convert both into the same units
2 cm -20 mm
Original - 8 mm
Painting -20mm
X - scale factor
20 = X * 8
X = 20/8 = 2.5
The ladybug has been multiplied/ enlarged by a scale factor of 2.5 to draw the painting

I believe it is D. Just ignore the 3 then subtract 2/7 from the 4/7, which is 2/7. Now put the 3 back and you'll have 3 4/7.
