Answer:
Step-by-step explanation:
Note that 80% is 8 times 10%.
Thus, we could start with "If 10% of a number is 7" and multiply both quantities by 8: "80% of a number is 56."
Think:
10% of a number is 7,
20% is 14,
50% is 35,
70% is 49, and
80% is 56.
Ok, so you want to substitute g and f in these equations so the f(x) = 2x+3x2-5 is equal to 10+6-5 or 11. The other equation is equal to 19. For the explanation put " I found this answer by substituting the given values for the variables in the equation". Your Welcome!
X = 2 + 4y
67 = x + y
67 = (2 + 4y) + y = 2 + 5y
65/5 = 13 = y
67 - 13 = x = 54.
x = 54
y = 13.
Rational. Ration number have an ending and irrational never end. 0.33 ends.
Hope that helps.
<u>Answer:</u>
x = 2, x = -3
<u>Step-by-step explanation:</u>
We are given the following quadratic equation and we are to solve it for x:
We need to find such factors of -6 that when added give a result of 1 and when multiplied, give a product of -6.
x = 2, x = -3
