2x + y = 10
5x - y = 18
7x = 28
x = 4
2(4) + y = 10
8 + y = 10
y = 2
(4,2)
Answer:
The answer is D (I'm 99.9999% positive it's the correct answer)
Step-by-step explanation:
It's kinda hard to tell with the pictures but look at the screenshot I attached bc that's how it should look :)
hope this helps :)

Answer:
(-1, -2)
Step-by-step explanation:
The difference between the coordinates of the image and the coordinates of the original is the same for both points.
X - (0, 2) = (5, 2) -(6, 6)
X = (5, 2) -(6, 6) +(0, 2) = (5-6+0, 2-6+2)
X = (-1, -2)
The image of the point after translation is (-1, -2).
Hello :
f(12) represent : <span>B. The value of (7x − 1) when x = 12</span>
Volume=height times area of base
base=circle so area of base=pir^2
ok so solume=height times pi times r^2
1.
thermos, h=10, r=2
therefor
volume=10pi2^2=
volume=10pi4=
40pi in^3 is brought to school
2. inside is 4 inches deep
h=4, r=1.5
volume=4pi1.5^2
volume=4pi2.25
volume=9pi
answer is 9pi in^3
3. so find 80% of 9pi
80%=0.8
0.8 times 9pi=7.2pi in^3
each times is 7.2pi in^3
4. ok so this is assuming that you fill the mug to 80% (7.2pi) each time and the remainder is it less or more or equal to half of 7.2pi so
total in thermos=40pi
each pour=7.2pi
40pi-7.2pi-7.2pi-7.2pi-7.2pi-7.2pi=4pi
is 4pi more or less than 7.2pi
7.2pi/2=3.6pi
4pi>3.6pi
it is MORE
1. 40pi in^3
2. 9pi in^3
3. 7.2pi in^3
4. MORE than half
