The answer to your question would be 60 percent all you do is divide that and move the decimal 2 places to the left.
Those 3 lines are:
y=2x+2
X=4
Y=4
The R satisfies these:
Y<2x+2
X<4
Y<4
Answer:
17
Step-by-step explanation:
The first thing to do is plug in the numbers for the equation. Starting with:
[-20-(-3)]/(19-20)
When you answer that you simplify the answer to
(-20+3)/(19-20)
You answer what is in the parenthesis first.
(-17)/(-1)
After this step you simplify.
17.
The answer is seventeen because any number over 1 is just the number. For example, 3/1=3. The answer is positive because the negative in the numerator and denominator cancel eachother out. leaving the answer as 17.
Answer:
a = ± 4
Step-by-step explanation:
Expressing the proportion in fractional form
= 
( cross- multiply )
(a -1 )(a + 1) = 15 ← expand factors on left side
a² - 1 = 15 ( add 1 to both sides )
a² = 16 ( take the square root of both sides )
a = ± 
= ± 4
