Answer:
X=7
Step-by-step explanation:
4x-(2x-9)=23 simplified would be
4x-2x+9=23
2x+9=23
2x=14
X=7
A:-) would be the correct answer because if 2/5 is 1/2 they size of 5 it would have to be 2/2-1/2.
Answer:
r = 11
Step-by-step explanation:
C = 2πr
69.08 = 2(3.14)r
69.08 = 6.28r
r = 69.08/6.28
r = 11
Given:
The given system of equations is
To find:
The solution of the given system of equations.
Solution:
We have,
...(i)
...(ii)
Left hand sides of both equations are equal. So, after equalization of (i) and (ii), we get
This statement is false for any value of x and y. It means the given system of equation has no solution.
Therefore, the correct option is C.
Answer:
B
Step-by-step explanation:
f(0) - f(-3) = area under f'(x) from x=0 to x=3.
We can find the area under f'(x) in this interval by finding the area of the triangle formed by the line.
A = 1/2 b h
A = 1/2 (3) (3)
A = 4.5
f(0) - f(-3) = 4.5
Since f(0) = 7:
7 - f(-3) = 4.5
f(-3) = 7 - 4.5
f(-3) = 2.5
