920,438. 921,438-1,000=920,438
Answer:
(-2,4)
Step-by-step explanation:
The solution is the point at which the two lines intersect, (-2,4). That point is the only one that satisfies (works) in both equations:
y = x + 6
4 = -2 + 6
and
y = -0.5x + 3
4 = -0.5(-2) + 3
4 = 1 + 3
====
You can also solve it algebraically:
y = x + 6
y = -0.5x + 3
-0.5x + 3 = x + 6 [Use the value of y from the second equation in the first equation]
-1.5x = 3
x = -2
Use this is y = -2 + 6:
y = 4
(-2,4)
Answer: 6/37
Step-by-step explanation:
Answer:
x=5+132,5−132x=\frac{5+\sqrt{13}}{2},\frac{5-\sqrt{13}}{2}
x=
2 5+√
13, 2 5−√
13
Step-by-step explanation: learn yourself
Since the question specifically asks about using a calculator, there's no point explaining how to do it (mostly because the buttons you have to press vary from model to model.
All we can tell you is that the calculator, depending on how many decimal digits it can store, will return something like 0.803802...
Even if there were millions of digits after the decimal point, that would still be an approximate value, since this number is irrational, i.e. it has infinite, non-repeating decimal digits.
