Slope: 1.5
y-intercept: -2
Explanation:
The slope is the number attached to 'x' in the equation. In this case, 1.5 would be the slope because it's attached to x.
The y-intercept is the constant the number not attached to any variables. In this case, -2 is all by itself.
Hope that helps!

Answer:
So, at 2 seconds the baseball reaches its maximum height and its maximum height is 69 feets.
Step-by-step explanation:
Answer:
your supposed to flip the sign for the less than or greater than sighs when dividing by a negative.
Step-by-step explanation:
-4x←20
x→-5
First we use sin(a+b)= sinacosb+sinbcosa
and cos(a+b)=cosa cosb -sinasinb
tan(x+pi/2)= sin(x+pi/2) / cos(x+pi/2)
and sin(x+pi/2) = sinxcospi/2 + sinpi/2cosx =cosx,
<span>cos(x+pi/2) = cosxcospi/2- sinxsinpi/2= - sinx,
</span> because <span>cospi/2 =0, </span>and <span>sinpi/2=1
</span><span>=tan(x+pi/2)= sin(x+pi/2) / cos(x+pi/2)= cosx / -sinx = -1/tanx = -cotx
</span>from where <span>tan(x+pi/2)=-cotx</span>
It’s the third one 9(5+1)
As 9 x 5 = 45
9x 1 = 9
