Solving Systems of Linear Equations - Item 9500
Question 2 of 7
Which choice is the most efficient first step to solve this set of equations?
Reference
y = 2x + 4
3x + 4y = 17
CLEAR
CHE
Language
y + 3x + 4y = 2x + 4 + 17
Add the two equations together
3x + 4(2x + 4) = 17
Substitute (2x + 4) for y
in the second equation
ENUE
3x + 4y - y = 17 - (2x + 4)
Subtract the first equation
from the second equation
y-(3x + 4y) = 2x + 4 - 17
Subtract the second equation
from the first equation

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere

i don't even know how to read that, ill try to do it if you translate it into english.

example answer: "to determine if a sum is reasonable you can round each number to the nearest whole and compare the estimated sum to the actual sum."

hope this you and anyone else who needs the answer : ^)
