Answer:
(3, 7)
Step-by-step explanation:
Just substitute x = 3 into the equations.
2(3) + 4y = 34
6 + 4y = 34
4y = 28
y = 7
Answer:
Step-by-step explanation:
y = 5x + 4
-5x + y = 4 ----------------------(i)
3x + 2y = 20 --------------------(ii)
Multiply equation (i) by (-2)
(i)* (-2) 10x - 2y = -8
(ii) <u>3x + 2y = 20</u> { Now add this two equations}
13x = 12 { -2y and 2y got eliminated}
x = 12/13
Plug in value of x in (i)
-5*12/13 + y = 4
-60/13 + y = 4
y = 4 + 60/13
I would help you, but sadly, i cannot read what the paper states.
Answer:
The answer is: 1.99<h<2.37
Step-by-step explanation:
The procedure is as followed
V=πr^2h
225=π(5.5)^2h
h=2.37
225=π(6)^2h
h=1.99
Answer:
3.5 =k
Step-by-step explanation:
If the table is proportional, the equation is
y = kx
To find k
y/x =k
14/4 = k
7/2=k
3.5 =k
