Answer:

(-3, 2)

Step-by-step explanation:

To find the coordinates of a point being reflected across the x-axis you need to use the rule (x, -y) on the point. Example: If the point was (4, 7) you would make the y value negative since it is positive, which would give you (4, -7) which is the point after being reflected across the x-axis. I know this one is for reflecting on the x-axis but for future problems if you want to reflect across the y-axis you do the same thing but with the x value, so (-x, y)

What does (d+3) represent in 4.5(d+3)=45

Scrat [10]

Answer:

(d + 3) would be 10

Step-by-step explanation:

<u>Step 1: Distribute</u>

$4.5(d + 3) = 45$

$(4.5 * d) + (4.5 * 3) = 45$

$4.5d + 13.5 = 45$

<u>Step 2: Subtract 13.5 from both sides</u>

$4.5d + 13.5 - 13.5 = 45 - 13.5$

$4.5d = 31.5$

<u>Step 3: Divide both sides by 4.5</u>

$\frac{4.5d}{4.5} = \frac{31.5}{4.5}$

$d = 7$

<u>Step 4: Determine what (d+3) is</u>

$(d + 3)$

$(7 + 3)$

$10$

Answer: (d + 3) would be 10

So sorry to ask another question but I need some help-

Vika [28.1K]

Answer:

14x + 23

Step-by-step explanation:

The lengths of three sides of a triangle are 5x + 9 feet, 2x + 14 feet, and 7x feet.

The perimeter of a triangle: the sum of all of its sides.

5x + 9 + 2x + 14 + 7x

14x + 23

It's the expression of the perimeter of the triangle. Once you will be asked to find x, you'll probably be given the exact perimeter of the triangle.
