Answer: Option A
Step-by-step explanation:
Given the functions f(x) and g(x):
indicates that you need to subtract the function and the function .
Then:
Now, you need to dstribute the negative sign and then you have to add like terms. Then:
You can observe that this answer matches with the option A.
Answer:
5:3
Step-by-step explanation:
16-(5+1)=10
Ratio is 10:6 reduced is 5:3
G(h(0)) = 20
h(x) = x+4
h(0) = 0+4
h(0) = 4
g(x) = 5x
g(h(0)) = g(4) = 5(4) = 20
I would say the original price was $512 because its now 1/4
so... 128 * 4= 512
Answer:
x = -1, y = 7
Step-by-step explanation:
8x + 3y = 13
3x + 2y = 11
Multiply the first equation by -2 and the second equation by 3. Then add them.
-16x - 6y = -26
(+) 9x + 6y = 33
--------------------------
-7x = 7
x = -1
Now substitute x = -1 in the first original equation and solve for y.
8x + 3y = 13
8(-1) + 3y = 13
-8 + 3y = 13
3y = 21
y = 7
Answer: x = -1, y = 7
