A leaky pool loses 2 and one-fourth inches of water each day. Jermaine and Mildred are asked to determine the change in the amou

nt of water in the pool over 5 days. Jermaine’s Solution Mildred’s Solution 5 (Negative 2 and one-fourth) = 5 (negative 2 minus one-fourth) = negative 10 minus one-fourth = negative 10 and one-fourth 5 (Negative 2 and one-fourth) = 5 (negative 2 minus one-fourth) = negative 10 minus StartFraction 5 over 4 EndFraction = negative 11 and one-fourth Which describes the reasoning used to determine whose solution is correct? Jermaine is correct because Negative 10 minus one-fourth equals Negative 10 and one-fourth Jermaine is correct because he distributed 5 correctly. Mildred is correct because she multiplied 5 by –2 but not by Negative one-fourth. Mildred is correct because she distributed 5 correctly.

Answer:

  Mildred is correct because she distributed 5 correctly

Step-by-step explanation:

We cannot tell exactly which solution goes with which student, but we believe you are saying ...

Mildred’s Solution:

  5 (Negative 2 and one-fourth) = 5 (negative 2 minus one-fourth)

  = negative 10 minus StartFraction 5 over 4 EndFraction

  = negative 11 and one-fourth

This solution describes the correct distribution of 5. Whoever it belongs to gave the correct solution.

What is the true solution to 3 in 2 + in 8 = 2 in (4x)
11Alexandr11 [23.1K]
The first step for solving this equation is to determine the defined range.
3㏑(2) + ㏑(8) = 2㏑(4x), x > 0
Write the number 8 in exponential form.
3㏑(2) + ㏑(2³) = 2㏑(4x)
Using ㏑(a^{x}) = x × ㏑(a),, transform the expression.
3㏑(2) + 3㏑(2) = 2㏑(4x)
Now collect the like terms on the left side of the equation.
6㏑(2) = 2㏑(4x)
Switch the sides of the equation.
2㏑(4x) = 6㏑(2)
Using x × ㏑(a) = ㏑(a^{x}),, transform the expression on the left side of the equation.
㏑((4x)²) = 6㏑(2)
Using x × ㏑(a) = ㏑(a^{x}),, transform the expression on the right side of the equation.
㏑((4x)²) = ㏑(2^{6})
Since the bases of the logarithms are the same,, you need to set the arguments equal.
(4x)² = 2^{6}
Take the square root of both sides of the equation and remember to use both the positive and negative roots.
4x = +/- 8
Now separate the equation into 2 possible cases.
4x = 8
4x = -8
Solve the top equation for x.
x = 2
Solve the bottom equation for x.
x = 2
         , x > 0
x = -2
Lastly,, check if the solution is in the defined range to find your final answer.
x = 2
This means that the correct answer to your question is x = 2.

Answer:

y+7 = -3 ( x-4)

Step-by-step explanation:

First find two points on the graph to find the slope

( 1,2) and ( 3,-4)

The slope is given by

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

m = ( -4-2)/(3-1)

    = -6/2

    =-3

We can use the point slope form

y - y1 = m(x-x1)  where m is the slope and x1,y1 is a point on the line

We have two choices with a slope of -3

We can either use and x coordinate of -2 or 4

for  -2, the y coordinate is not shown

for 4 , the y coordinate is -7

Using ( 4, -7) and m = -3

y--7 = -3( x- 4)

y+7 = -3 ( x-4)

Identify the polygon and classify it as regular or irregular.
Ray Of Light [21]
A regular hexagon has sides that are all congruent and angles that all measure 120 degrees. This means the angles of a regular hexagon add up to 720 degrees. ... An irregular hexagon has sides that are not the same measurement and can have points facing inward as well as outward.
