The line that goes through the points (0,-4) and (1,2) is......
shepuryov [24]

Answer: The equation for the line is “y = 6x - 4”

Step-by-step explanation: To find this answer we will put it in slope-intercept form which is y = mx +b. To first find m which is the slope you subtract the the second y by the first y over the second x by the first x. It looks like this y2 - y1/ x2 - x1. After we find the slope which is 6, to find the y-intercept which is b we just plug a point we used to find the slope into the equation we have. It looks like this y = 6x + b —> 2 = 6(1) + b... I used (1,2). Then you solve for b by multiplying 1 by 6 and then subtracting 6 to both sides to get b by itself. So it goes from 2 = 6(1) + b into -4 = b. Then you just put -4 into b and you get the answer y = 6x - 4.

Have a nice day!

If anyone can help with either one that’d be great
Volgvan

4.  Solve

1430 = 0.55t^2 + 550

1430 - 550 =880 = 0.55t^2

880/0.55 = 1600 = t^2

t= \pm \sqrt{1600} = \pm 40

On the positive answer makes sense.

Answer: Month 40

5. The throw ends when the height is zero (I guess we're ignoring rolling).

0 = -0.02x^2 + x + 6

x = \dfrac{-1 \pm \sqrt{1^2 - 4(6)(-0.02)}}{2(-0.02)}

Only the negative sign for the plus/minus will give a sensible, positive answer:

x = \dfrac{-1 - \sqrt{1^2 - 4(6)(-0.02)}}{2(-0.02)} = 55.4138

Answer: 55.4 feet
