Answer:

a), b), e)

Step-by-step explanation:

<em>a) -30(3 + 2w) = -90 - 60w</em>

<em>b) (-9 − 6w) x 10 = -90 - 60w</em>

c) -3(30 - 20w) = -90 + 60w

d) (6 + 4w) × 15 = 90 + 60w

<em>e) −20(4.5 + 3w) = -90 - 60w</em>

Determine if the equations are parallel, perpendicular, or neither.
Aloiza [94]
To easily find the slope from standard form (Ax + By = C) use -A/B

1. m = -5/3
2. m = -3/5

perpendicular slopes are negative reciprocals, which these are not

parallel slopes are exactly the same, which these are also not

so, these equations are neither parallel nor perpendicular

the quadratic function h (t)=-16t^2+150 models a balls height, in feet, over time, in seconds, after it is dropped from a 15 sto
natulia [17]
Hello! Lets solve this :)
So for the first question :
h(t) = -16t^2 + 150
h(0)= -16 (0)^2 + 150
h(0)= -16(0) + 150
h(0)= 0 + 150
h(0)= 150 feet

Second question
We need to find here the time when the ball hit the ground; or when the height h(t) is 0.
In equation form
h(t) --> 0=16t^2 + 150
16t^2 = 150
t^2=150/16
t= <span>√150/16
t= 5</span><span>√6/4
t= 5 (2.45)/4
t= 3.06 seconds
</span>
Hope this helps! If you have any other questions or would like further explanation just let me know! :)
