Answer:
Step-by-step explanation:
Subtract the 680 from 960, then divide the product by 52000 to get the answer
The range is {y|y ≤ 6}.
The function is increasing over the interval (–∞ , –2).
The function is decreasing over the interval (−4, ∞).
The function has a positive y-intercept.
we have
using a graph tool
see the attached figure
Statements
case 1) The domain is {x|x ≤ –2}
Is false. the domain is all real numbers---------> interval (-∞,∞)
case 2) The range is {y|y ≤ 6}.
Is true
Is a parabola open down, the vertex is the point
the range is the interval ------> (-∞,-6]
case 3) The function is increasing over the interval (–∞ , –2).
Is true (see the graph)
case 4) The function is decreasing over the interval (−4, ∞)
Is false
In the interval (-4,-2) the function is increasing and in the interval (-2, ∞) the function is decreasing
case 5) The function has a positive y-intercept
Is true
The y-intercept is the point
therefore
the answer is
The range is {y|y ≤ 6}
The function is increasing over the interval (–∞ , –2)
The function has a positive y-intercept

Answer: To find out how many weeks it will take for Alex to have enough money to buy the smartphone, we need to use the following formula:
weeks=rategoal−saved
where:
goal is the amount of money he needs to buy the smartphone, which is 550$
saved is the amount of money he has already saved, which is 250$
rate is the amount of money he saves per week, which is 30$
Plugging in these values, we get:
weeks=550−250/30
Simplifying, we get:
weeks=300/30
Dividing, we get:
weeks=10
Therefore, it will take Alex 10 weeks to have enough money to buy the smartphone. I hope this helps.
Answer:
Not including the 250$ he already saved, it would take Alex 10 weeks to have to 550$ he needs to buy the smartphone.
Step-by-step explanation:
Subtract 250 from 550 and then divide the difference by 30, since Alex plans on saving 30$ per week. The result is 10, which is your answer.
Hope this helps you!
