Answer:
y= 1x - 1
Step-by-step explanation:
Slope-intercept form: y=mx + b
(-4,-5) (5,4)
m= (y2 - y1)/(x2 - x1) = (4+5)/(5+4)=1
4=1(5)+b
4=5 + b 4-5=b b= -1
y= 1x - 1
Answer:
The height of the toy is 9 feet after 1 second
Step-by-step explanation:
we have
![h(t)=-2t^2+7t+4](https://tex.z-dn.net/?f=h%28t%29%3D-2t%5E2%2B7t%2B4)
where
h(t) is the toys height from the ground
t is the time in seconds
so
For t=1 sec
substitute the value of t in the quadratic equation and solve for h(t)
![h(1)=-2(1)^2+7(1)+4](https://tex.z-dn.net/?f=h%281%29%3D-2%281%29%5E2%2B7%281%29%2B4)
![h(1)=9\ ft](https://tex.z-dn.net/?f=h%281%29%3D9%5C%20ft)
Answer:
3:2 , 3/2, 3 to 2
Step-by-step explanation:
The best one is 3:2 cause it is the most used way to write a ratio. 3:2 also means 3 divided by 2 or 3 out of 2 so that's why you would use the other 2.
