It is given in the question that

Anna buys 12 pens and 20 pencils for a total cost of $16. One pen costs $0.40 more than a pencil.

Let the cost of pencil is $ x .

Therefore cost of pen is

$(x+0.40)

According to the question

12(x+0.40)+20x =16

Distributing 12 and combining like terms, we will get

12x+4.8+20x=16\\32x = 11.2\\x = 0.35

Therefore cost of pencil is $0.35 and cost of pen is

0.35+0.40=0.75

Which graph shows the quadratic function y = 3x2 − 12x + 10? (5 points)
eduard

ANSWER

The graph in option D.

EXPLANATION

The given function is:

y = 3 {x}^{2}  - 12x + 10

We complete the square to obtain:

y = 3( {x}^{2}  - 4x) + 10

y = 3( {x}^{2}  - 4x +  {( - 2)}^{2} ) + 10  -  3 {( - 2)}^{2}

y = 3{( x- 2)}^{2}+ 10  - 12

y = 3{( x- 2)}^{2}  - 2

The graph of this function opens upwards and has its vertex at (2,-2).

The y-intercept is 10.

From the options the graph that satisfies all these properties is D.
