1/4*x - 1/6*y= 5 |*18
4/5 *x + 3/8*y = 10 | *8
18/4*x -3*y= 90
32/5*x + 3y = 80
-------------------------
18/4*x+32/5*x / = 170
The answer is a
Answer:
(x-7)(x-2)
Step-by-step explanation:
what multiples to 14, but add to -9 ?
-7*-2 = 14
-7*-2= -9
Answer:
f(h(-1)) = -1
Step-by-step explanation:
f(x) = (x-4)/3
h(x) = 3x + 4
f(h(-1)) = ?
So first off we need to solve for h(-1):
h(x) = 3x + 4
h(-1) = 3(-1) + 4
h(-1) = 1
Next, we plug this value into the f(x) equation:
f(x) = (x-4)/3
f(1) = (1-4)/3
f(1) = -1
f(h(-1)) may look confusing but it is just f(x) with x being the resulting value for h(-1)
Thus we can say that f(h(-1)) is equal to -1
180 - 149 = 31
x/100 *149 = 31
1.49x = 31
x= 31/1.46 = 20.81 %
The answer is 2x+6
Explanation: 2 times 3 is 6 and 2 times x is 2x
