Answer:
(1,-12)
Step-by-step explanation:
-10+5y=-50
5y=-60
y=-12
10x-60=-50
10x=10
x=1
The set contains only vowels
2b: If x is 2.1, then one side of the rectangle is 2.1, and another is 2.1*5=10.5. Thus, the perimeter is 2*(2.1+10.5)=2*12.6=25.2.
3: One side of the square with side-length three will not be on the outside, so we have 3*3=9 inches perimeter from the square of side-length 3. The square of side-length 6 has 3 from the top side missing from the outer perimeter, because it coincides with a side of the square of side-length three. This square contributes 6*4-3=33 inches. The total perimeter is 33+9=42 inches.
This function represents exponential decay.
We know it's exponential because the value the base (200) is being multiplied by is being raised to the power of x.
In this case, the multiplication value is 0.8, which is less than 1.
If the multiplication value is less than 1, than the function will decay, rather than grow.
In this case, the factor is 0.8, or 80%.
Answer:
all real numbers
Step-by-step explanation:
The domain is the numbers that the input, x, can take
We can put in any real number for x since there are no restrictions on the input
