Match each expression with an equivalent expression.

Marysya12 [62]

Answer:

$6x-4y$ → 4. $2(3x-2y)$

$6-4x$ → 3. $2(3-2x)$

$6x-4x$ → 1. $2x$

$6x-4$ → 2. $2(3x-2)$

Step-by-step explanation:

You need to:

Factor out 2 from $6x-4y$ , then you get the equivalent expression:

$=2(3x-2y)$ this matches with OPTION 4

Factor out 2 from $6-4y$ , then you get the equivalent expression:

$=2(3-2x)$ this matches with OPTION 3

Make the subtraction for $6x-4x$ , then you get the equivalent expression:

$=2x$ this matches with OPTION 1

Factor out 2 from $6x-4$ , then you get the equivalent expression:

$=2(3x-2)$ this matches with OPTION 2

Volume of a Cylinder Formula: $\displaystyle V = \pi r^2h$

V is volume
r is radius
h is height

Step-by-step explanation:

Step 1: Define

Radius r = 2 ft

Height h = 7 ft

Step 2: Solve for V

Substitute in variables [Volume of a Cylinder Formula]: $\displaystyle V = \pi (2 \ ft)^2(7 \ ft)$
[Volume] Evaluate exponents: $\displaystyle V = \pi (4 \ ft^2)(7 \ ft)$
[Volume] Multiply: $\displaystyle V = 28 \pi \ ft^3$

1. If you are asked to use elimination to solve for x", what do you need to multiply the bottom equation by to eliminate "y?

hram777 [196]

Answer:

-5

Step-by-step explanation:

There is different ways to solve methods of elimination but if you wanted to cancel y out you would multiply by the opposite sign....for example

7x + 5y = 19

-5 (2x + y = 19) ---> -10x -5y = 95

this would cancel out your y to solve for x so you can plug it back in and solve! hope this helps!!!
