Answer:

B

Step-by-step explanation:

speed is determined by the gradient

car 1 gradient = change in y / change in x =  \frac{85 - 75}{17 -15} = \frac{10}{2} = 5

car 2 gradient = 10

so car 2 is travelling faster than car 1

Answer:

A few examples:

0. 0

1. Undefined

2. -3/5

3. Undefined

...

7. 493

8. 5/2

....

Learn how to find the slope below for the other problems.

Step-by-step explanation:

Slope is the rate of change for a linear function. It is found by subtracting the y values of two point on the line and dividing that difference by the difference of the x values of the points.

It can also be found using the formula y=mx+b known as the slope intercept form.

Here are a few examples:

0. This is a horizontal line which always has slope 0.

1. This is a vertical line which always has slope undefined.

2. Find two points that cross through a grid line intersection The line appears to cross them at (5,3) and (0,6). Count the unit squares between the two by counting up 3 and over to the left 5. Because it is left it is negative. The slope is -3/5

3. To find the slope, use the slope formula:

\frac{y_2-y_1}{x_2-x_1}=\frac{6--4}{-2--2}=\frac{6+4}{-2+2}=\frac{10}{0}=undefined

Since we can't divide by 0, it is undefined.

7. y=493x-257 follows the formula y=mx+b where m is the slope. m=493. The slope is 493.

8. Covert the equation into y=mx+b by rearranging the terms using y=mx+b.

5x-2y=48

-2y=48-5x

y=5/2 x -24

So the slope is 5/2.

show whether each equation has one solution, infinitely, many solutions or no solutions: 2x+7=-8x-9+10x​
alexira [117]

Answer:

  1. The statement is <em>false</em>
  2. There is<em> no solution</em>

Step-by-step explanation:

Step 1: <em>Collect the like terms</em>

2x+7 = -8x-9+10x

2x+7 = 2x-9

Step 2: <em>Cancel</em><em> </em><em>equal</em><em> </em><em>terms</em><em> </em><em>of</em><em> </em><em>both</em><em> </em><em>sides</em><em> </em><em>of</em><em> </em><em>the</em><em> </em><em>equation</em>

2x+7 = 2x-9

7 = -9

Result: The statement is <em>false</em> and there is <em>no solution</em> as 7 is <em>not equal</em> to -9.

I hope this helped ! ;)

Answer:

1) x=1; x= 0 is an extraneous solution

Step-by-step explanation:

5 = 4x + 1

5 = 4 x 1 + 1

5 = 5

x = 1
