-(3x-2)=-4(x+1)-4
-3x+2=-4(x+1)-4
Use distributive property for -4(x+1)
-3x+2=-4x-4-4
-3x+2=-4x-8
Add 4x to each side
-3x+2+4x=-4x-8+4x
x+2=-8
Subtract 2 to each side
x+2-2=-8-2
x=-10
Check:
-(3x-2)=-4(x+1)-4
-(3×10-2)=-4(-10+1)-4
-(30-2)=-4(-9)-4
32=32, so x=-10. Hope it help!

Suppose you deposited $100 in a savings account 4 years ago with a simple interest rate of 2.2%.

Principal P= $ 100

Time t = 4 years

rate of interest = 2.2 %

Formula of simple interest

Plugging the value in formula

simple interest =

simple interest = $ 8.8

Can someone explain this step by step please

kobusy [5.1K]

Answer:

x = - 2

y = 6

Step-by-step explanation:

The best way to do this is to put - 3x in for y in the second equation.

4x - 2(-3x) = - 20 Watch the signs. You have 2 minus signs.

4x - - 6x = -20 Change - - 6x to 6x

4x + 6x = - 20 Add

10x = - 20 Divide by 10

x = -20/10

x = - 2

============================

Find y

y = - 3x

y = -3 * -2

y = 6

An airplane flies from City 1 at (0, 0) to City 2 at (33, 56) and then to City 3 at (23, 32). What is the total number of miles

uranmaximum [27]

Answer:

The airplane flies 95 miles.

Step-by-step explanation:

First we need to find the distance for the first segment using the formula for distance $D=\sqrt{(x_{2}-x_{1})^2 + (y_{2}-y_{1})^2}$ . Let's say $(x_{1},y_{1})$ is (0, 0) and $(x_{2},y_{2})$ is (33, 56). This gets us that the length of this segment is 65 miles.
Next, we need to find the distance for the second segment. Using the same formula for distance $D=\sqrt{(x_{2}-x_{1})^2 + (y_{2}-y_{1})^2}$ , we can say $(x_{1},y_{1})$ is now (33, 56) and $(x_{2},y_{2})$ is now (23, 32). This gets us that the length of this segment is 26 miles.
To get the total distance traveled, add the length of these two segments together (65 miles + 26 miles) to get 91 total miles traveled.
