If y = 3x squared + 4 find the value of y when x = 2
qaws [65]

Answer:

The value of y is 16.

Step-by-step explanation:

You have to substitute x = 2 into the equation :

y =  {3x}^{2}  + 4

Let x = 2,

y = 3( {2)}^{2}  + 4

y = 3(4) + 4

y = 12 + 4

y = 16

Check the picture attached.

Let m(BAE)=m(ACD)=α

(BAE and ACD are congruent, since they are alternate interior angles, or Z angles)

Let m(ABE)=β. 

So in triangle ABE, the measures of the angles are 90, α and β degrees.

This means that m(BCE)=β, since the 2 other angles of triangle BCE are 90 and α degrees.

thus, we have the similarity of triangles ABE and BCE,

so the following rations are equal:

\frac{AB}{BC} = \frac{BE}{CE} = \frac{AE}{BE}

so


\frac{AB}{BC} = \frac{x}{5} = \frac{8}{x}

so 

\frac{x}{5} = \frac{8}{x}

x^{2} =40

x= \sqrt{40}= \sqrt{4*10}=2 \sqrt{10}   (inches)


Remark, we can also apply Euclid's theorem directly.

Last weekend , 5% of tickets sold at sea world were discount tickets. If seaworld sold 60 tickets in all , how many discount tic
Dafna1 [17]
So lets take a look at what we know:

5% of the tickets were discount
100% of the tickets is equal to 60 tickets

From this information we can create the proportion:

\frac{x}{5} = \frac{60}{100}.

Cross Multiply to get 100x=300

Divide 100 on each side to get x=3 .

Three discount tickets were sold.
