Is there anyone that can help me with this

That is called the Transitive Property. Since y=z and x=z, x=y. Another order sounding a little better is since y=z and z=x, y=x.

How do you do this problem?

astra-53 [7]

By substitution is how to solve

2x-3y=21
y=3-x

2x-3(3-x)=21
2x-9+3x=21
5x=30
x= 6

now substitute our x value into y=3-x
so we get

y=3-6 = -3

so x=6 and y=-3 hope this helps!!!!! Thank you!

Find all solutions of the equation in the interval [0, 2π). cotθ+ √3= 0

Ilia_Sergeevich [38]

Answer:

{5π/6, 11π/6}

Step-by-step explanation:

Since you have memorized the trig values of common angles, you know tan(π/6) = 1/√3, so cot(π/6) = √3.

The solution to this equation is ...

cot(θ) = -√3

so θ = -π/6 or, in the domain of interest, 11π/6. There is a corresponding quadrant II angle, 5π/6.

Greg is in a car at the top of a roller-coaster ride. The distance, d, of the car from the ground as the car descends is determi

ANTONII [103]

Answer:

It takes 3 seconds over the interval [0,3]

Step-by-step explanation:

To find when the roller coaster reaches the ground, find when d=0.

$0=144-16t^2$

To solve divide each term by 16 and factor:

$\frac{0}{16}=\frac{144}{16} -\frac{-16t^2}{16} \\0= 9 - t^2\\0=(3-t)(3+t)$

Solve for t by setting each factor to 0.

t-3=0 so t=3

t+3=0 so t=-3

This means the car is in the air from 0 to 3 second.
