Answer: L=90-10t
0-90
1-80
2-70
3-60
Step-by-step explanation:
that should be right lol
because it decreases by ten a week so just count down by ten each week. Then, you can make the equation 90-10t and if you substitute each week for t it is true.
90-10(0)=90-0=90
90-10(1)=90-10=80
and so on...
Answer:
The answer is 21/35 or 3/5
Step-by-step explanation:
35-14=21
Answer:
Step-by-step explanation:
Values true of 'x' for equation x² + 2x = 24 is -6 and 4
If the equation has roots of +-3i. The equation would be,
(x + 3i)(x - 3i)
which is equal to x^2 - (3i)^2 = x^2 + 3.
Using division either by synthetic or long method,
(x^3 + x^2 + 9x + 9)/(x^2 + 3)
is equal to,
x + 1 or x = -1
Thus, the answer is the second choice.
