Answer:

The number of feet she will travel back is 1 or 7 feet

Step-by-step explanation:

Here, we need to solve the quadratic equation

That will be as follows;

0 = x^2 -8x + 7

x^2-x-7x+ 7 = 0

x(x-1)-7(x-1) = 0

(x-1)(x-7) = 0

x = 1 or 7

The number of feet she will travel before coming back to the surface of the water is 1 or 7 feet

(a) Complete the table of values for the graph x + y = 6
djyliett [7]

Answer:

(0,6)

(1,5)

(2,4)

(3,3)

(4,2)

Step-by-step explanation:

To solve this table first convert the equation to slope-intercept form (y=mx+b), to do this solve for y in the equation. The slope-intercept form is y=-x+6, where -1 is the slope and 6 is the y-intercept. Then from that, you can get your first point, because you know the y-intercept is 6, therefore when x equals 0 y must be 6. Next, because the slope is -1 that means the y-value decreases by 1 every time the x-value increases by 1. So to find the rest of the y-values simply subtract 1 from the previous y-value.

When beans are cooked, the amount of water required varies directly with the cups of beans. If 2 cups of beans require 4.5 cups
marishachu [46]

Answer:

11.25 cups of water is needed to cook 5 cups of Beans.

Step-by-step explanation:

Given:

The amount of water required varies directly with the cups of beans.

2 cups of beans require 4.5 cups of water.

we need to find how many cups of water are needed to prepare 5 cups of beans.

4.5 cups of water =2 cups of bean

Number of cups of water = 5 cups of bean.

Now Using Unitary method for solving above we get,

Number of cups of water required = \frac{5\times4.5}{2}=\frac{22.5}{2}=11.25 \ cups

Hence 11.25 cups of water is required to prepare 5 cups of beans.
