Answer:

y = (4/3)x

Step-by-step explanation:

Remember that the origin is located at (0,0). Thus, we have 2 points on this line: (0,0) and (3,4). Going from (0,0) to (3,4), x increases by 3 and y by 4. Thus, the slope of this line is m = rise/run = 4/3. Since the line goes thru the origin, the y-intercept is b = 0, and so the equation of this line is y = (4/3)x.

<h2><u>DIRECT RULE OF 3</u></h2>

We use a rule of 3 to solve it.

Let's record the data:

253 miles → 8 hours

‎ x miles → 7 hours

‎

Let's solve:‏‏‎

$\mathsf{x = \dfrac{7(253)}{8}}$

$\mathsf{x = \dfrac{1771}{8}}$

$\large{\boxed{\mathsf{x = 221,375}}}$

‎ ‏‏‎

<h3><u>Answer</u>. The car can travel 221,375 miles in seven hours.</h3>

Given the angles in the diagram, what is the angle measurement of the missing angle?

Eva8 [605]

Answer:

150*

Step-by-step explanation:

Using the formula (n -2) x 180* we find that there is 4 sides (n) and in put it and simplify to make (2)x180*. From there we calculate there is 360* in this polygon, and subtract the degrees already provided. 360-210=150

Answer:

Rx)=1/3x^2

Step-by-step explanation:

A horizontal stretch is simply making the parabola of the parent function wider, it's kind of like changing the slope of a line to make it less steep.

In the graph, the red line is the parent function and the blue line is the horizontally stretched function. See how the blue line appears to be stretched (horizontally).
