A scalene triangle is formed from the three points.
Answer:
c ≤ -14/17
Step-by-step explanation:
-32c+12 ≤-66c-16
-32c+12-12 ≤-66c-12-12
-32c ≤-66c-28
-32c+66c ≤-66c-28 +66c
34c ≤-28
34c/34 ≤-28/34
Answer:
14.2 years
Step-by-step explanation:
The multiplier of the population each year is 1 +5% = 1.05, so after n years the population has been multiplied by 1.05^n. You want to find the value of n that makes this expression equal to 2:
2 = 1.05^n
log(2) = n·log(1.05) . . . . . take logarithms
log(2)/log(1.05) = n ≈ 14.2
Growing at a rate of 5% per year, it will take about 14.2 years for the population to double.
10x -4 (x - 2) = 80
10x + (8 + -4x) = 80
<span>8 + 10x + -4x = 80
</span>8 + 6x = 80
<span>8 + -8 + 6x = 80 + -8
</span><span>6x = 80 + -8
</span>6x = 72
<span>x = 12</span>
