Answer: x = 9/4, y = 7/6
║<span>2x + 3y = 8
</span>║<span>4x - 6y = 2
</span>║4x + 6y = 16
║4x - 6y = 2
Add both equations together:
8x = 18
x = 9/4
Sub x = 9/4 into 2x + 3y = 8
2(9/4) + 3y = 8
9/2 + 3y = 8
3y = 7/2
y = 7/6
Answer:
That's correct.
Step-by-step explanation:
I'm pretty sure...
Given that the bacteria has been modeled by the function:
r(t)=(450.267)e^(1.12567t)
thus the number of bacteria after 3 hours will be:
r(3)=450.267e^(1.12567×3)
r(3)=13,185.20623
The number of bacteria after 3 hours will be:
13, 185.20623
Step-by-step explanation:
b.
The sum of two opposite interior angles equals one exterior angle
111°=60°+‹G
‹G=111°-60°=51°
c.
We use the same property above
3x+4x+5=68°
7x=68-5
7x=63
x=63/7=9
‹D=4(9)+5
‹D=41°
