Answer:

Unit rate is often a useful means for comparing ratios and their associated rates when measured in different units. The unit rate allows us to compare varying sizes of quantities by examining the number of units of one quantity per one unit of the second quantity. This value of the ratio is the unit rate.

4)

the arrow touches the ground when the heigth is 0

so we need to replace h=0 and solve for t

\begin{gathered} h=17t-5t^2 \\ 0=17t-5t^2 \\ 0=t(17-5t) \\ 0=17-5t \\ 5t=17 \\ t=\frac{17}{5}=3.4 \end{gathered}

<em>the arrow tuches the ground at 3.4 seconds</em>

5)

F=m\times a

replacing

185=m\times13.7

<em>solve for m</em>

\begin{gathered} m=\frac{185}{13.7} \\  \\ m=13.50 \end{gathered}

<em>the mass is 13.50Kg</em>

fenix001 [56]
<span>m//n if the external alternating angles are equal, that means:
(3x+12)°=48°

Solving for x:
3x+12=48
3x+12-12=48-12
3x=36
3x/3=36/3
x=12

Answer: Option B. 12</span>

The graph shows one of the linear equations for a system of equations. Which equation represents the second linear equation for
erastova [34]

Answer:

  C)  2/3x + 3y = 3

Step-by-step explanation:

The attached graph shows only choice C intersects the desired point.

Essentially, the given graph is irrelevant. What you want to know is which equation has (3/4, 5/6) as a solution.

There are at least a couple of ways you can figure this out:

  1. try the given point in the equations to see which one works
  2. examine the features of the given equations to see which might work

__

If we consider the second approach, we realize all of the equations have negative y-intercepts except choice C*. For an equation with a negative y-intercept to be the solution, the x-intercept must be less than 3/4. That is not the case for any of choices A, B, or D, leaving only choice C as a viable possibility.

We can check to see if the given point satisfies choice C. Filling in for x and y, we get ...

  (2/3)(3/4) + 3(5/6) = 2/4 +5/2 = 3 . . . . . . the point is on this line

_____

In the attached graph, choice C is the black line.

_____

* For an equation of the form ax+by=c, the y-intercept is c/b and the x-intercept is c/a. The sign of the quotient can be figured from the signs of a, b, and c without doing any division.

_____

<em>Comment on intercepts</em>

Considering the signs and values of the x- and y-intercepts can tell you a lot about the solution to a system of equations. They tell you where the line segment between the axes lies, and they can give you a clue as to the location (quadrant) of the intersection point of two lines. Often, the intercepts are all you need to create a useful graph of an equation.
