Answer: x= -4
Step-by-step explanation:
Combine like terms
-4x -7 -3x + 4 = 25
-7x -3 =25
Add 3 on both sides
-7x=28
Divide by -7 on both sides
x= -4
Hope this helps! :)
Answer:
y = x/3 - 2 or f(x) = x/3 - 2
Step-by-step explanation:
f(x) = y
y = 3x + 6
To solve for inverse change y to x and x to y and solve for y.
x = 3y + 6 //Subtract 6 on both side
x - 6 = 3y //Divide 3 on both side
x/3 - 6/3 = y //Simply
y = x/3 - 2
Answer:
see below
Step-by-step explanation:
Small bag
95p / 250 g * 12/12 to get to 3 kg = 1140 p / 3000g =11.40£s/ 3 kgs
Medium bag
1.8£ / 500 g * 6/6 to get to 3 kg = 10.8£ / 3000g =10.80£/ 3 kgs
Large bag
3.7£ / 3 kg *
To answer this problem, we can use the power rule such that the result of the operations of the powers on the left side is equal to power on the right side. In this case, the right side's power is 200. On the left side, the tentative sum is 60 - 18 or equal to 42. Thus, the remaining exponent to be added on the left side is 158. Answer is x^158
Since the toss can either be heads or tails and only one of these can land at a time the answer is 13
