Leto [7]

Answer:

10 and like 2/3 of a book

Step-by-step explanation:

8 books divided by 3 months would be 2 and 2/3 a month, and if they are both going the same rate each month, Jesse would be reading 10 and 2/3 books in 4 months.

Find the minimum y-value on the graph of y=f(x)<br><br> F(x) = 7x^2 + 7 - 6
Kisachek [45]

Answer:

The minimum y-value is

y=-\frac{31}{4}  or  y=-7.75

Step-by-step explanation:

we have

f(x)=7x^{2}+7x-6

This is the equation of a vertical parabola open up

The vertex is the minimum y-value on the graph

Convert the equation into vertex form

Group terms that contain the same variable, and move the constant to the opposite side of the equation

f(x)+6=7x^{2}+7x

Factor the leading coefficient

f(x)+6=7(x^{2}+x)

Complete the square. Remember to balance the equation by adding the same constants to each side

f(x)+6+1.75=7(x^{2}+x+0.25)

f(x)+7.75=7(x^{2}+x+0.25)

Rewrite as perfect squares

f(x)+7.75=7(x+0.5)^{2}

f(x)=7(x+0.5)^{2}-7.75 ------> equation in vertex form

The vertex is the point (-0.5,-7.75)

therefore

The minimum is the point (-0.5,-7.75)

The minimum y-value is y=-7.75=-7\frac{3}{4}=-\frac{31}{4}

Confused on this so please help:
scoray [572]

The equation p=4+3y is maximised at (4,5) and the maximised value is 31.

Given equation p=4x+3y and constraints x>0,x<4, y<5.

We have to maximise the equation p=4x+3y with constraints x>0,x<4,y<5.

To find out the points we have to make graphs of the constraints first.

From the graph we have found that points are (0,0),(0,5),(4,0),(4,5).

The above points are common points of graphs of all constraints.

The value of equations are as under:

At (0,0) , p=4*0+3*0=0

At (0,5), p=4*0+3*5=15

At (4,0),p=4*4+3*0=16

At (4,5),p=4*4+3*5=16+15=31

Maximum value of p is 31 and that is for (4,5).

Hence the equation is maximised at (4,5) and the maximum value is 31.
