Answer:

option 1, 3x + 4 = 8x = 10

Step-by-step explanation:

The graph given contains system of equations. Common point or point of intersection of these lines will be the solution set of the given system.

One line has the y intercept = 4

So equation should be in the form of y = mx + 4

second line has the y - intercept = (-10)

so equation will be solved by

mx + 4 = m'x - 10

Option 1 is in this form so option 1 3x + 4 = 8x = 10 will be answer.

A) 3x + 4 = 5x - 10. It's easy to identify the lines' equations by their y-intercept and slope.

If £2000 is placed into a bank account that pays 3% compound interest per year, how much will be in the account after 2years?
AVprozaik [17]
3% = 3/100 = 0,03

When it's compount interest it's 1,03 because you gain 3% more from what you already have.

All you need to do
1,03•2000=2060$ for the first year

And then for the second year, you take the actual amount after one year of 3%

1,03•2060=2121,8

After two years, there will be 2121,8$

Which fraction has a terminating decimal?<br> - 11/19<br> - 4/7<br> - 1/3<br> - 3/150
babunello [35]
<h3>Answer: D) 3/150</h3>

==========================================================

Explanation:

With the use of a calculator, we see that,

  • 11/19 = 0.57894736842106...., the decimals eventually repeat; but unfortunately my calculator ran out of room to show the repeating portion
  • 4/7 = 0.5714285714285714..., the block "571428" repeats forever
  • 1/3 = 0.333333.... the 3s go on forever
  • 3/150 = 0.02

So 3/150 converts to the terminating decimal 0.02

The word "terminate" means "stop". In the other decimal values, the decimal digits go on forever repeating the patterns mentioned.

----------------------

A non-calculator approach will have us simplify 3/150 into 1/50 after dividing both parts by the GCF 3. Then notice how 50 has the prime factorization of 2*5*5. The fact that the denominator 50 can be factored in terms of only 2's and 5's is enough evidence to conclude that the fraction converts to a terminating decimal.

If the denominator factors into some other primes, other than 2s and 5s, then we don't have a terminating decimal. So that's why 11/19, 4/7 and 1/3 convert to non-terminating decimals.
