Answer:

125+25n

Step-by-step explanation:

We are given that

Heather opens a bank account with=$125

Each week she deposited money into her account=$25

We have to find the explicit rule for amount of money which has Heather after n weeks.

Heather has money after 1 week=125+25=$150

Heather has money after 2 week=125+2(25)=$175

Heather has money after 3 weeks=125+3(25)=$200

Heather has money after n weeks=125+25(n)

Hence, the explicit rule for amount of money which has Heather after n weeks is given by

125+25n

Which expression results from using the distributive property 2(5 + r)

Vinvika [58]

Using the distributive property we know we distribute by multiplying the outside values to those inside of the parentheses

outside values: 2

inside values: 5 and r

now multiply out inside values by the outside values

2x5 = 10

2xr = 2r

now plug these values back in for the inside values and take away the outside value and the parentheses

so 2(5+r) using the distribution property is 10+2r

A company rents two storage units. Both units are cube- shaped. What is the difference in volume of the two storage units? Note

Mariulka [41]

Answer:

The difference between their volumes is $237.375ft^3$

Step-by-step explanation:

The attachment completes the question.

For cube 1:

$s_1 = 8ft$

For cube 2:

$s_2 = 6.5ft$

Required

The difference in their volumes

First, we calculate the volume of box 1

$V_1 = s_1^3$

Substitute 8 for s1

$V_1 = 8^3$

$V_1 = 512ft^3$

Next, we calculate the volume of box 2

$V_2 = s_2^3$

Substitute 6.5 for s2

$V_2 = 6.5^3$

$V_2 = 274.625ft^3$

The difference is then calculated as:

$Difference = |V_1- V_2|$

$Difference = |274.625- 512|$

$Difference = |-237.375|$

$Difference = 237.375$

Hence, the difference between their volumes is $237.375ft^3$

Is M a midpoint of line AB= ? AB= 27 and MB =14 <br> A maybe <br> B can’t be <br> C no <br> D yes

My name is Ann [436]

The answer is B/C.—M is in fact NOT a midpoint of line AB. This is because to be a midpoint the distance between both endpoints and the midpoint must me equal. If AB has equaled 28 then is would be, but in this case NO. To get AM you just need to do 27-14. AM would be 13 (if you need that too)

SOMEONE PLEASE HELP ANSWER MY QUESTIONS!!!!!!!!!!!!

Semmy [17]

1)
$y=mx+b$
where m is the slope

We know the slope is 5 and the line passes through the point (4,3).

$m=5 \\
(4,3) \\
x=4 \\ y=3 \\ \\ 
3=5 \times 4 + b \\
3=20 + b \\
b=3-20 \\
b=-17$

The equation of the line is:
$y=5m-17$

Now the second point:
$(2,y) \\
x=2 \\
y \\ \\ y=5 \times 2 -17 \\ y=10-17 \\ y=-7$

The answer:
The value of y is -7.

2)
The line passes through the origin, or the point (0,0), and has a slope of -32.
The slope is negative so the line goes down from left to right.
It crosses both x and y axes in the point (0,0).
Therefore, it only passes through II and IV quadrant.

You can also find the equation of the line, find one more point and draw it.
$y=mx+b \\ \\
m=-32 \\
(0,0) \\
x=0 \\ y=0 \\ \\
0=-32 \times 0 + b \\
b=0 \\ \\
y=-32x$

Find the y-coordinate of the point for example (1,y).
$(1,y) \\
x=1 \\ y \\ \\
y=-32 \times 1 \\
y=-32$

The line passes through the points (0,0) and (1,-32). Now you can draw it (see the attachment).

The answer:
The line passes through quadrants II and IV.
