Answer:

=−3x+3y+15

Step by Step:

2y − 4x + 14 − 6y + 3x − 8 − 2x + 9 + 7y

=2y +−4x + 14 +−6y + 3x +−8 +−2x + 9 + 7y

Combine Like Terms:

=2y +−4x +1 4 +−6y + 3x +−8 +−2x + 9 + 7y

=(−4x + 3x +−2x) + (2y +−6y + 7y) + (14 +−8 + 9)

=−3x + 3y + 15

It helps to seperate the variables. Maybe highlighting the x one color y's another color and constant another. just so you can see the different numbers. it gets confusing looking at everything all together.

The volume of a sphere is two-thirds of a cylinder. What is the volume of a cylinder that has the same diameter as a sphere with
sattari [20]

Answer:

V_2= \frac{28}{3} u^3

Step-by-step explanation:

Given

Represent the volume of the cylinder with V1 and the volume of the sphere with V2

So, from the first statement: we have:

V_2 =\frac{2}{3}V_1

and

V_1 = 14u^3

To solve for V_2, we simply substitute 14u^3 for V_1 in V_2 =\frac{2}{3}V_1

V_2 =\frac{2}{3}V_1

V_2= \frac{2}{3} * 14u^3

V_2= \frac{2* 14}{3} u^3

V_2= \frac{28}{3} u^3

Hence, the volume of the sphere is \frac{28}{3} u^3

Laura retired from her job recently, and she has saved about $396,460.00 over the course of her career. She plans to withdraw $1
Tomtit [17]
So she has 396460
she will withdarw 1700 per month, and withdraw is loss or minus or (-)

after x months, she has 359060 left so

total-withdrawn=remaining
withdrawwn=1700 times months so withdrawn=1700x
total-1700x=remaining
total=396460
reaining=359060
subsitute
isolate x then divide is the strategy

396460-1700x=359060
add 1700x to both sides
396460=359060+1700x
subtract 359060 from both sides
37400=1700x
divide both sides by 1700
22=x

she has been retired for 22 months
