<u>ANSWER</u>
A. (4,12)
<u>EXPLANATION</u>
The equations are:
and
To eliminate a variable we make the coefficients of that variable the same in both equations.
It is easier to eliminate x.
We multiply the first equation by 2 to get:
We add equations (2) and (3).
Divide both sides by 23
Put x=4 into equation (1).
The solution is (4,12)
Answer:
2z+14
Step-by-step explanation:
you multiply
4*z =4z
4*2 =8
and then you multiply
2*3=6
2*-z=-2z
the answer is 2z+14
<em>Good luck, you'll need it :)</em>
Answer:
not a solution
Step-by-step explanation:
y < 7x + 8
Substitute (2-,-6) into the inequality
-6 < 7(-2) +8
-6 <-14+8
-6 <-6
This is not true because they are equal not less than
Volume of the cylinder can be calculated as:
V=πr²h
Radius = r = 4
Height = h = 7
π = 3.14
Using the values, we get:
V = 3.14 (16) (7) = 351.68 cubic units
So the answer to this question is 351.68
