Step 1) Combine like terms/variables.

7y and -2y are similar, combine them.
7+(-2y)=5y

3x has no similar variables, so it stays the same

3 and 6 are similar, without variables, combine them.
3+6=9

The final answer is 5y+3x+9

Answer:no, it is not 9y + 3x +9

Step-by-step explanation:

7y + 3x + 3 - 2y + 6

we can re-arrange the expression for easy operation

7y -2y + 3x + 3 + 6

5y + 3x + 9.

2. Find the area of the shaded region. Express your answer in terms of
In-s [12.5K]

Answer:

Step-by-step explanation:

Find the area of the rectangle. A = length * width

Find the area of each circle.   A = π*radius*radius

Subtract the area of each circle from the area of the rectangle.

A = length * width

A = (3+6+9+12) * 18

A = 30 * 18

A = 540 square inches

Bottom circle

A = π * radius * radius.  (radius is 1/2 of the diameter)

A = 3.14 * 6 * 6

A = 133.04 square inches

Middle circle

A = π * radius * radius

A = 3.14 * 4.5 * 4.5

A = 63.59 square inches

Top circle

A = π * radius * radius

A = 3.14 * 3 * 3

A = 28.26 square inches

Subtract the circles from the rectangle.

540 - 133.04 - 63.59 - 28.26 = 315.11 square inches is the area of the shaded part.

What slope would make the lines<br> parallel?<br> y = -3x + 9<br> y = [?]x + 4
Vladimir79 [104]

Answer:

- 3

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - 3x + 9 ← is in slope- intercept form

with slope m = - 3

Parallel lines have equal slopes, thus

y = - 3x + 4 ← is the equation of a parallel line
