Adam rode in a bike-a-thon. At the end of each hour of the bike-a-thon, he recorded the total distance he had traveled since the

bike-a-thon began. This is shown in the table below. Based on this table, is the total distance traveled by Adam a function of time?

Which orderd pair is a solution to this equation? -2x-y=4
nevsk [136]
To find the ordered pair solution, you need to find the zero(s) (which are the x-values for which y is equal to zero). This is called the Zero Product Property. Here's the math:

-2x-y=4             convert the equation into slope form

-y=2x+4            multiply both sides by -1

y=-2x-4             convert into factored form

y=-2(x+2)          now, we need to find what x equals that makes y equal zero

0=-2(x+2)          replace y with zero

0/-2=x+2           divide both sides by -2

-2=x                  x=-2 when y=0

Therefore, the zero of the equation (aka the solution) is the ordered pair (-2,0). 

Answer: (-2,0)

If you have access to a graphing calculator, you can just convert the equation to y=mx+b form and enter it as a function. The solution is wherever the graph intercepts the x-axis. Hope this helps!

Amanda [17]
The answer is 3.075. 
If you divide 12.30 4 you'll get 3.075.

Answer/Step-by-step explanation:

Given:

Line equation => 2.1x + 9.9y - 9.2 = 0

Required:

x-intercept and y-intercept of the line.

SOLUTION:

The x-intercept is the point where the line intercepts the x-axis. To find the x-intercept of the line for which the equation is given above, set y = 0 and solve for x.

2.1x + 9.9(0) - 9.2 = 0

2.1x + 0 - 9.2 = 0

2.1x - 9.2 = 0

2.1x - 9.2 + 9.2 = 0 + 9.2

2.1x = 9.2

\frac{2.1x}{2.1} = \frac{9.2}{2.1}

x = 4.4 (approximated)

The y-intercept is the point where the line intercepts the y-axis. At this point, x = 0. Set x = 0 and solve for y to find the y intercept.

2.1(0) + 9.9y - 9.2 = 0

9.9y - 9.2 = 0

9.9y - 9.2 + 9.2 = 0 + 9.2

9.9y = 9.2

y = \frac{9.2}{9.9}

y = 0.9 (approximated)

Please help with these math questions

1. Slope intercept form is y=mx+b, where m is slope and b is y-intercept. 
It gave you point (8,12) and slope of -2. 
So you already know the value of m, so so far it's y = -2x + b. 
Plug the coordinates as x and y: 8 for x and 12 for y.
12 = -2(8) + b
12 = -16 + b
28 = b

Adding b in, you get y = -2x + 28

2. Find the slope, then use point-slope form.
Slope is change in y over change in x, or (y2-y1)/(x2-x1). 
m = (9-1)/(2-3) = 8/(-1) = -8

Point slope form: y - y1 = m(x - x1)
y - y1 = -8(x - x1)
Now plug in either of the coordinates as x1 and y1, let's do (3,1). 
y - 1 = -8(x - 3)
y - 1 = -8x + 24
y = -8x + 25

3. Do it the same way as number 2. Choose two points, for example (1,1) and (2,-2). You find m = -3 and get final answer as y=-3x + 4.

4. B = 150 + 80d 
B is account balance, d is number of monthly deposits.
If you rearrange the terms: B = 80d + 150, you see that that is in slope-intercept form y = mx+b, and if you remember from #1 m is the slope. In this case, the variables are changed, so d is the slope here. And the question told you that d, the slope, is the number of monthly deposits. Its coefficient is 80, so Bianca deposits $80/month.

<span>5. </span>
14a + 16b = 560
16b = 560 - 14a
b = (560 - 14a)/16
b = 560/16 - 14a/16
b = 35 - (7/8)a
<span>b = -(7/8)a + 35</span>
