Ok so the first step would be to distribute 3 into 3x and -6. So 3 times 3x would be 9x. 3 times -6 is -18.

the equation now is
18 = 9x - 18

Now you would have to do inverse operation

18 = 9x - 18
+18 +18

36 = 9x

Now you would divide 9x into 36 to isolate the variable

36 / 9x = 4
x = 4

9x = 36
x = 4
bc 3 timea 3x is 9x and 3 times -6 is -18. Then move -18 to the other side by adding so 18+18 is 36. 36 = 9x and you would solve for x... x= 4

The square below represents one whole. Express the shaded area as a fraction, a decimal, and a percent of the whole. Fraction: D

Igoryamba

Answer:

Fraction = $\frac{19}{50}$

Decimal = 0.38

Percent = 38%

Step-by-step explanation:

Number of shaded rectangles = 38

Total number of rectangles = 100

Fraction represented by the shaded area = $\frac{\text{Number of blocks shaded}}{\text{Total number of blocks}}$

= $\frac{38}{100}$

= $\frac{19\times 2}{50\times 2}$

= $\frac{19}{50}$

Decimal form of the shaded area = $\frac{38}{100}$ = 0.38

Percent of the shaded area = $\frac{38}{100}$ = 38%

triangle abc has vertices at a(-2 3),B(0,3),c(-1,-1). Find the coordinates of the image after a reflection over the x-axis.

Crazy boy [7]

The new coordinates of the triangle after reflection from x-axis would be A(-2, -3) , B(0, -3) and C( -1, 1 )

<u>Explanation:</u>

The vertices of the triangle are A(-2 3), B(0,3), C(-1,-1)

The reflection is over the x-axis.

When the reflection is along the x-axis, the coordinates of x does not change. However, the coordinates of y does change.

The negative value of y becomes positive and the positive value of y becomes negative.

Similarly,

A(-2, 3) would become A(-2, -3)

B(0, 3) would become B(0, -3)

C(-1, -1) would become C( -1, 1 )

Therefore, the new coordinates of the triangle after reflection from x-axis would be A(-2, -3) , B(0, -3) and C( -1, 1 )
