yulyashka [42]

To find the equation we will put the values of x and y in the equations and then check if LHS=RHS.

$\large\red{\sf{y=3x-1}}$

x=1
y=9

$\begin{gathered}\\ \sf\longmapsto 9=3(1)-1\end{gathered}$

$\begin{gathered}\\ \sf\longmapsto 9=3-1\end{gathered}$

$\begin{gathered}\\ \sf\longmapsto 9≠2 \end{gathered}$

$\large\green{\sf{y=5x+4}}$

$\begin{gathered}\\ \sf\longmapsto 9=5(1)+4\end{gathered}$

$\begin{gathered}\\ \sf\longmapsto 9=5+4\end{gathered}$

$\begin{gathered}\\ \sf\longmapsto 9=9\end{gathered}$

$\large\blue{\sf{y=-2x-8}}$

$\begin{gathered}\\ \sf\longmapsto 9=-2(1)-8\end{gathered}$

$\begin{gathered}\\ \sf\longmapsto 9=-2-8\end{gathered}$

$\begin{gathered}\\ \sf\longmapsto 9≠10\end{gathered}$

$\large\pink{\sf{y=6x-8}}$

$\begin{gathered}\\ \sf\longmapsto 9=6(1)-8\end{gathered}$

$\begin{gathered}\\ \sf\longmapsto 9=6-8\end{gathered}$

$\begin{gathered}\\ \sf\longmapsto 9≠-2\end{gathered}$

Hence, Option B. y=5x+4 satisfies the system (1,9)

A ball is thrown at an initial height of 7 feet with an initial upward velocity at 27 ft/s. The balls height h (in feet) after t

lianna [129]

Answer:

The height of ball is 17 ft at t=0.55 and t=1.14.

Step-by-step explanation:

The general projectile motion is defined as

$y=-16t^2+vt+y_0$

Where, v is initial velocity and y₀ is initial height.

It is given that the initial height is 7 and the initial upward velocity is 27.

Substitute v=27 and y₀=7 in the above equation to find the model for height of the ball.

$h(t)=-16t^2+27t+7$

The height of ball is 17 ft. Put h(t)=17.

$17=-16t^2+27t+7$

$0=-16t^2+27t-10$

On solving this equation using graphing calculator we get

$t=0.549,1.139$

$t\approx 0.55,1.14$

Therefore the height of ball is 17 ft at t=0.55 and t=1.14.

The symbol ∪ represents the union of events. The union of two events A and B results in an event that contains all the sample po

Degger [83]

Answer:

AUB = {E1, E2, E4, E6, E7}

Step-by-step explanation:

Since we are to look for the union of the two sets, therefore we combine all the sample points that are contained in A and B without repeating any sample even if such sample occur in both sets. For example, E4 occurs in event A and B and as such will only be repeated once in the union of the two events.

AUB = {E1, E2, E4, E6, E7}

Note that the way you arrange does not matter as well.

I hope you find this solution useful?
