Let
a------------> first number
b------------> second number
we know that
a+b=-7--------> a=-7-b----------> equation 1
a-b=14--------> equation 2
<span>I substitute 1 in 2
</span>
(-7-b)-b=14-------------> -7-b-b=14----------> -7-2b=14-------> 2b=-7-14
2b=-21---------> b=-10.5
a=-7-b-------> a=-7-(-10.5)-----> a=-7+10.5------> a=3.5
the answer is
the two numbers are
a=3.5
and
b=-10.5
D because there’s a pattern. Pattern for x is that it’s adding by one. Pattern for y is that it’s adding by 15
Answer:
0 is real number, rational number, integers, whole numbers,
6^-3 / 6^5
Because the numerator has a negative exponent, use the negative exponent rule b^-n = 1/b^n
To do this move 6^-3 to the denominator:
1 / (6^5 * 6^3)
When you multiply identical numbers with exponents you add the exponents so (6^5 * 6^3) becomes 6^8
Now you have 1 / 6^8
Now raise 6 to the power of 8 to get:
1/1679616
Depending on the format your answer needs to be in you have 3 different answers:
1) 1/6^8 ( Leaving it as an exponent)
2) 1 / 1679616 (As a fraction)
3) 5.9537 x 10^-7 (As a decimal, round as needed)
