Given: A(-7,8), M(-3,6) find the midpoint

1 answer:

7 0

To find the midpoint, you can think of it logically or use the formula. I will explain logically. To do this, first find the distance between the x values and the y values. The distance in x values is 4 and the distance in y values is 2. Then to get the middle, you should divide each by 2 and then add those values to the one that is lower and more onto the left so you get the midpoint as (-5,7)

Which of the following is a valid exclusion for the algebraic fraction 8ab^2x/4a^2b-8ab^2

Molodets [167]

Answer:

a ≠ 2b

Step-by-step explanation:

The given expression is

$\frac{8ab^{2}x}{4a^{2}b-8ab^{2}}$

$=\frac{8ab^{2}x}{4ab(a-2b)}$

Simplifying it, we have

$\frac{8ab^{2}x}{4a^{2}b-8ab^{2}} = \frac{bx}{a-2b}$

For the above fraction to exist, the denominator must not be equal to zero.

i.e, a-2b ≠ 0

=> a≠2b

∴ The algebraic fraction exists when a≠2b.

IS this table linear?? Can someone please explain???? What would the weight be if the number of weeks in the fitness program was

boyakko [2]

Answer:

not linear
somewhere between 184 and 186 (maybe)

Step-by-step explanation:

As you show, the weight differences are different for the same week differences, so the table is not linear. A graph (attached) can also show you the table is not linear.

The highest rate of weight loss shown in the table is 7 lbs in 3 weeks, or 4 2/3 pounds in 2 weeks. The lowest rate of weight loss shown in the table is 5 lbs in 3 weeks, or 3 1/3 pounds in 2 weeks. Based on the rates shown in the table, we might expect the starting weight to be between 3 1/3 and 4 2/3 pounds more than the first table value:

Week 0 weight: between 184 1/3 and 185 2/3 lbs, estimated.

_____

A "line of best fit" for the data has a y-intercept of about 185 pounds, which is the midpoint between our two estimates above.
