5 0

Answer:

1, 3, and 4 would be correct answers

Step-by-step explanation:

1.) <u>-x - 2x - 3y - 2y + 1 + 1 = -3x -5y + 2</u>

2.) -3x + 2y + 3y + 2 = -3x + 5y + 2

3.) <u>-3x - y - y - y - y - y + 2 = -3x - 5y + 2</u>

4.) <u>-x - x - x - y - y - y - y - y + 1 + 1 = -3x - 5y + 2</u>

5.) x + x + x + y + y + y + y + y + 1 + 1 = 3x + 5y + 2

Hope this helps!

timofeeve [1]

\text{Hey there!}

\bf{9.83+8.2(7.01)}

\text{You could solved this equation by doing PEMDAS}

\text{PEMDAS simply means}\downarrow

\text{Parentheses }

\text{Exponents}

\text{Multiplication}

\text{Division}

\text{Addition}

\text{Subtraction}

\text{In your equation you have \bf{MULTIPLICATION \& ADDITION}}

\text{Now,  that we have every information we need.. lets solve the problem}

\text{We have to do \underline{MULITPLICATION} first then \underline{ADDITION} last}

\text{9.83 + 8.2(7.01)}

\text{8.2(7.01)=57.482}

\text{9.83 + 57.482 = 67.312}

Find the coordinates of P ' if D o, 2.4 (x,y) is applied to the triangle below
guajiro [1.7K]

Answer:

The coordinates of P' are (4.8,-4.8).

Step-by-step explanation:

The rule of dilation D_{o,2.4}(x,y) represent the dilation with scale factor 2.4 and center at origin.

If the scale factor of the dilation is k and the center is (0,0), then

(x,y)\rightarrow (kx,ky)

Since the scale factor is 2.4, therefore

(x,y)\rightarrow (2.4x,2.4y)

From the given figure it is noticed that the coordinates of P are (2,-2). The coordinates of P' are

P(2,-2)\rightarrow P'(2.4(2),2.4(-2))

P(2,-2)\rightarrow P'(4.8,-4.8)

Therefore the coordinates of P' are (4.8,-4.8).

(100+ POINTS)
horsena [70]

Answer:

1) 102.7 meters

2) 11

Step-by-step explanation:

1) -4.9x² + 75x = -4.9x² + 50x + 38

25x = 38

x = 1.52 s

Height = -4.9(1.52)² + 75(1.52) = 102.67904 m = 102.7 m

2) f(x) = x² + 3x - 2

f(2) = 2² + 3(2) - 2 = 8

f(6) = 6² + 3(6) - 2 = 52

Average rate of change:

(52-8)/(6-2) = 11
