Answer:
(x,y)=(1,5)
Step-by-step explanation:
6x+3y=21/*2
-12x+y=-7
12x+6y=42 (1)
-12x+y=-7 (2)
(1)+(2): 7y=35
-12x+y=-7
y=35/7
-12x+y=-7
y=5
-12x+5=-7
y=5
-12x=-7-5
y=5
-12x=-12
y=5
x=-12/(-12
y=5
x=1
(x,y)=(1,5)
Answer:
C
Step-by-step explanation:
I took the quiz before:3
Answer: The answer is y= -3 sin(2x) which is C
Step-by-step explanation:
Because I got it right
S) This question is asking me to find the volume of the backpack.
O) Identify the facts: compartment one is 14x3x10, compartment two is 12x2x10, Julissa got a new backpack
Eliminate the unnecessary facts: Julissa got a new backpack
List the necessary facts: compartment one is 14x3x10, compartment two is 12x2x10
L) I chose Multiplication, I will multiply the measurements of compartment one, then multiply the measurements of compartment two and add them together to find the volume of the backpack.
V) I think the backpack will be at least 300 inches cubed.
(SOLVING PART)
Compartment one: 12 times 2 times 10 = 240
Compartment two: 14 times 3 times 10 = 420
420 + 240 = 660
E) Julissa’s backpack is 660 inches cubed.
I hope this helps
