Answer:
4
Step-by-step explanation:
The y-variable can be eliminated by adding 3 times the first equation to the second:
3(2x -y) +(x +3y) = 3(11) +(-5)
7x = 28 . . . . simplify
x = 4 . . . . . . . divide by 7
_____
Using Cramer's Rule, you can also find the x-value. The math is not so different.
x = ((-1)(-5) -(3)(11))/(-1(1) -3(2)) = -28/-7 = 4
The answer is -16 - 10i.
Using the distributive property on the first part, we have:
-2i*7--2i*4i + (3+i)(-2+2i)
-14i+8i² +(3+i)(-2+2i)
Using FOIL on the last part,
-14i+8i²+(3*-2+3*2i+i*-2+i*2i)
-14i+8i²-6+6i-2i+2i²
-10i+8i²-6+2i²
Since we know that i = -1,
-10i+8(-1)-6+2(-1)
-10i-8-6-2
-16-10i
It depends on the type of negative financial information that is on your credit report. For example, an account that has undergone the collections or delinquency process can stay on your credit report for up to 7 years. Car loans may stay on your credit report for up to 10 years. However, it really depends on the type of account, and the account company. Some accounts will report positive payments after collections within 30 days. Others may take longer.
There are any number of ordered pairs that work for this equation. Below are some examples.
(0, -18) (2, -10) (5, 2)
In order to find these and any others, you simply select a value for x and plug into the equation to find y. Below is an example.
y = 4x - 18
y = 4(0) - 18
y = 0 - 18
y = -18
(0, -18)
Answer:
(C) 5
Step-by-step explanation:
Let x represent number of hours.
We have been given that running on a 10-mile loop in the same direction, Sue ran at a constant rate of 8 miles per hour.
Distance covered by Sue in x hours would be miles.
We are also told that Rob ran at a constant rate of 6 miles per hour, so distance covered by Rob in x hours would be miles.
Since Sue needs to complete one more loop than Rob, so difference of distances covered by Sue and Rob's in x hours should be equal to 10 miles.
We can represent this information in an equation as:
Therefore, 5 hours later Sue will complete exactly 1 more lap than Rob and option C is the correct choice.
