The graph of the quadratic function y = ax^2 + bx + c is given.<br> Find a + b + c.
andrey2020 [161]

Answer:

\frac{145}{24}\approx 6***

Answers may vary depending on the person reading the graph.

It is hard to tell what they think crosses nicely.

For example, I decided that the graph crossed nicely at the following points:

(0,3)

(2,8)

(6,5)

Step-by-step explanation:

I see that the graph crosses at (0,3),(2,8), and (6,5).

The equation y=ax^2+bx+c tells us the y-intercept is c since when x=0 we have y=a(0)^2+b(0)+c=0+0+c=c.

The y-intercept for our graph is 3. Therefore, c=3.

So far we have the equation:

y=ax^2+bx+3.

Let's enter the other points creating a system of linear equations to solve:

8=a(2)^2+b(2)+3

5=a(6)^2+b(6)+3

Let's simplify:

8=4a+2b+3

5=36a+6b+3

Let's subtract 3 on both sides:

5=4a+2b

2=36a+6b

I choose to solve the system by elimination.

Let's multiply the top equation by -3:

-15=-12a-6b

2=36a+6b

Now adding the equations results in:

-13=24a

Divide both sides by 24:

\frac{-13}{24}=a

Now using one of the equations we can find b:

5=4a+2b with a=\frac{-13}{24}

5=4\frac{-13}{24}+2b

5=\frac{-13}{6}+2b

Add 13/6 on both sides:

5+\frac{13}{6}=2b

\frac{30+13}{6}=2b

\frac{43}{6}=2b

Divide both sides by 2:

\frac{43}{2(6)}=b

\frac{43}{12}=b

So we have the equation:

y=\frac{-13}{24}x^2+\frac{43}{12}+3

Let's evaluate a+b+c now:

\frac{-13}{24}+\frac{43}{12}+3

\frac{-13+86+72}{24}

\frac{73+72}{24}

\frac{145}{24}

At the amusement park, Laura paid $6.00 for a small cotton candy. Her older brother works at the park, and he told her they mark
Anastasy [175]
Sure it's possible... set up the problem by thinking 6 dollars is 300% of what number.

6 = 300% × x
6 = 3.00x
6/3 = x
2 = x

Before the markup the cotton candy costs $2.00

Helppppp, if you could show your work too that would be so amazing!!

Answer:

  x = 6

  PM = 50

  MQ = 50

  PQ = 100

Step-by-step explanation:

The two halves of the segment are the same length:

  PM = MQ

  7x +8 = 5x +20

  2x = 12 . . . . . . . . . subtract 5x+8

  x = 6 . . . . . . . . . . . divide by 2

  PM = 7(6)+8 = 42+8

  PM = 50

  MQ = 5(6) +20 = 30+20

  MQ = 50

  PQ = PM +MQ = 50 +50

  PQ = 100
