Answer:

  • Option A

Step-by-step explanation:

<u>At Step 2 you subtract 1/2 from both sides of the equation:</u>

  • 1/2r = - 2/7r - 29/7 - 1/2
  • 1/2r = - 2/7r - 58/14 - 7/14
  • 1/2r = - 2/7r - 65/14

<u>Its justification is therefore is:</u>

  • A) The subtraction property of equality

subtract \frac{1}{2}from both sides of the equation:

\frac{1}{2r} = \frac{2}{7r} -  \frac{29}{7}-\frac{1}{2}

\frac{1}{2r} = \frac{2}{7r}  - \frac{58}{14}- \frac{7}{14}

\frac{1}{2r}  = \frac{2}{7r} -\frac{65}{14}

<u>Its justification is therefore is:</u>

  • A) The subtraction property of equality

The Viera family is traveling from Philadelphia to Orlando for vacation. The equation y=1000-65x represents the distance in mile
baherus [9]
1) Graph a straight segment that starts at the point (0, 1000) and (200/13 , 0)

That segment is in the first quadrant and is like a ramp going downward from left to right.

2) a) slope = - 65 is the change in y (the # of miles remaiing) per miles run (change in x). It is negative because when the Vieras have increase the distance run (x), the distance remaining (y) decreases.

b) the y - intercept (1000) representes the distance from the starting point (Philadelphia) fo the destiny (Orlando), i.e. the distance in miles remaining before departing (when x =0).

Given f(x) = x^2 – 3x – 2, what is f(5)?
miskamm [114]

Answer:

f(5)=8

Step-by-step explanation:

Given function: f(x)=x^2-3x-2

To find f(5), simply input x=5 into the function:

\begin{aligned}\implies f(5) & =5^2-3(5)-2\\& = 25-15-2\\& = 10-2\\& = 8\end{aligned}

Given the speeds of each runner below, determine who runs the fastest.
Lesechka [4]

Answer:

Debbie runs 9 feet per second: 9 ft/s

Jessica runs 1 mile  in 440 seconds: 414/50 ft/s = 207/25 ft/s = 8 7/25 ft/s

jesssica runs 131 feet in 10 seconds: since 1 mile = 5280 ft we have 1/470 mi/s = 5280/470 ft/s = 528/47 ft/s = 11 11/47 ft/s

ron runs 603 feet in 1 minute: 547 ft/min = 603/60 ft/s = 201/20 ft/s = 10 1/20 ft/s

Since:

11 11/47 > 10 1/20 > 9 > 8 7/25

Emily runs the fastest.
