A box is to be constructed with a rectangular base and a height of 5 cm. If the rectangular base must have a perimeter of 28 cm,

which quadratic equation best models the volume of the box? V = lwh P = 2(l + w) y = 5(28 – x)(x) y = 5(28 – 2x)(x) y = 5(14 – x)(x) y = 5(14 – 2x)(x)

Perimeter = 2(width+length) =28
Let x=width of base, then length of base = (28/2)-x = 14-x
Volume of box = length*width*height
=x(14-x)*5 = 5x(14-x)

A line has a slope of 2. It passes through the points (1, 2) and (3, y) . What is the value of y? y=
malfutka [58]

Answer:

6

Step-by-step explanation:

To solve this , we use the equation of finding a slope wig a line.

m = (y2 - y1)/(x2 - x1)

From the question, we know that:

y2 = y

x2 = 3

y1 = 2

x1 = 1

m = 2

Hence,

2= (y - 2)/(3 - 1)

2 = (y - 2)/2

4 = y - 2

y = 2 + 4 = 6

Select the point that is a solution to the system of inequalities​
ExtremeBDS [4]
<h3>Answer: B.  (-1, 0)</h3>

This point is below both the red diagonal line and the blue parabola. We know that the set of solution points is below both due to the "less than" parts of each inequality sign.  

In contrast, a point like (2,2) is above the parabola which is why it is not a solution. It does not make the inequality y \le x^2-3x true. So this is why we can rule choice A out.

Choice C is not a solution because (4,1) does not make y \le -x+3 true. This point is not below the red diagonal line. We can cross choice C off the list.

Choice D is similar to choice A, which is why we can rule it out as well.

Find the rate of change and initial value. Y=mx+b
tekilochka [14]
Y= 4/5 x + 24
To find the rate of change you find the difference in each of the numbers on the graph. For example, 36-32 is 4. So 28-4 is 24 and that would be the next number down. It would also match x to be 0 because since the rate of change for x was 5, if you subtract 5 from 5 you get 0. So from this we know that the coordinates would be 0,5.
From this info, the slope would be 4/5 and the y intercept or initial value would be 24

What is an equation of the line that passes through the points (0, -1)(0,−1) and (6, 1)(6,1)?
horrorfan [7]

slope = y2 - y1 \div x2 - x1

1 -  - 1 \div 6 - 0

2 \div 6

1 \div 3

y = mx + c

1 = 1 \div 3 \times 6 + c

1 = 2 + c

c = 3

y = 1 \div 3x + 3
