F(x) = (x + 3)²
g(x) = f(x) - 7.
g(x) = (x + 3)² - 7
g(x) = (x + 3)(x + 3) - 7
g(x) = x*x + x*3 +3*x + 3*3 - 7
g(x) = x² + 3x + 3x + 9 - 7
g(x) = x² + 6x + 2
Answer:
n > 3
Step-by-step explanation:
Given
3n + 6 > 15 ( subtract 6 from both sides )
3n > 9 ( divide both sides by 3 )
n > 3
In 10 years they would drift apart 250 kilometers.
Answer:
all real values
Step-by-step explanation:
there is no value for x, where the operations in f(x) would run into an undefined or outright invalid situation. whatever x we can think of, f(x) will calculate a valid y.
Answer:
Total he earns in 8 2/5 weeks=$680.40
Step-by-step explanation:
Reynolds paints 45 yards in 1 week, the number of yards he paints in 8 2/5 is expressed as= The average number of yards he paints in a week×number of weeks he paints= (8 2/5)×45=(42/5)×45=378 yards
He gets paid $0.60 per foot
1 yard=3 feet
Convert 378 yards to feet= 378×3=1134 feet
Total amount he earns=(Number of feet painted×cost per foot)
Total amount he earns=(1134×0.6)=$680.40
