Answer:
Step-by-step explanation:
2x + y = - 2
<u>x + y = 5 </u> Subtract to get rid of the y
x = -2-5
x = -7
Answer:
y = 18·8^x
Step-by-step explanation:
We assume you want a model that looks like y = ab^x.
To find the values of "a" and "b", you can fill in the given numbers and solve the system of equations:
18 = a·b^0
9216 = a·b^3
The first equation tells you ...
18 = a
Dividing the second equation by the first gives ...
9216/18 = (a·b^3)/(a·b^0) = b^3
512^(1/3) = b = 8
The exponential function is ...
y = 18·8^x
Answer:
The highest/greatest common factor of 1080, 1188, and 1815 is 3. :)
Answer:

Step-by-step explanation:
As the six-sided number cube had six sides, there are six events which could occur. There is only one interger less than 2 (1), therefore the probability of rolling a number less than 2 is
.
There are two events which could occur when flipping a coin. This means the probability of flipping heads is
.
To find the probability of both of these happening, you must multiply the fractions together by multiplying together both the denominators and numerators, therefore:
×
=
