3x-7y=21 what is the x entercept and y entercept

Answers

Answer 1

Answer: to find the x-intercept set y=0 and solve for x.
3x-7y=21
3x-7(0)=21
3x=21
x=7
so, x-intercept is at (7,0)
to find the y-intercept set x=0 and solve for y.
3x-7y=21
3(0)-7y=21
-7y=21
y=-3
so, y-intercept is at (0,3)

A population of 500 beetles is expected to grow at a rate of 70% per week.Which number is the best prediction of the population after 15 weeks?
1380
2862
525,000
1,431,212

Answers

The number of beetles after 15 weeks = 1,431,212

Calculating total population

The total number of beetles = 500

The rate at which the beetle should grow = 70% per week

Therefore 70% of 500= 70/100 × 500

=35000/100

= 350 per week.

That is every week there would be additional 350 beetles

which is = 500 + 350 = 850 beetles

850/500 = 1.7 times what it was the beginning of the week

Therefore in 15 weeks = 500× 1.7^15

= 500 × 2862.4231

= 1,431,212
