Y varies directly as the square of x. When x = 3, y = 18. What is the value of x when y = 72?A. 6
B. 8
C. 12
D. 54
Please help!
Answers
Answer: The answer is 12
Step-by-step explanation: Because if you divide 18y by 72y it will equal 4. Then you would just mutiply that number (4) by the original x (3), and you would get 12

Answer:
The correct answer is C= $99.400
Step-by-step explanation:
You need to sum all he has and then rest all he owes
The car has a balance of 20000 owed so 38000-20000=$18000 to sum
%195000+$5000+$1400+$180000=$219400
Then you rest what he owes= $219400-$120000=$99400

The Answer is C=$99400
The car has a balance of 20000 owed so 38000-20000=$18000 to sum
Answer:
A) 96,600
Step-by-step explanation:
"Balance of $1,400 on his credit cards" refers to a debt of $1,400, meaning you need to subtract it from his savings
Credit card: $5,000 - $1,400 = $3,600
Home: $195,000 - $120,000 = $75,000
Car: $38,000 - $20,000 = $18,000
Net: $3,600 + $75,000 + $18,000 = $96,600

What is the y-intercept of this graphed line?
PLEASE HELP!!!!!!
Answers
The y-intercept is when a point passes through the y-axis. Hope this helps:)
Final answer:
To find the y-intercept of the given linear function, first, the slope of the function is calculated using the provided points. Then, the slope and one pair of coordinates are substituted into the y = mx + b equation to solve for 'b', which is the y-intercept.
Explanation:
In mathematics, specifically in the context of linear functions, the y-intercept is the point at which the line crosses the y-axis. From the provided points, however, it's not immediately clear what the y-intercept is.
To find the y-intercept, we need to determine the line's equation first. The equation of a line can be represented in the form y = mx + b, where 'm' is the slope of the line and 'b' is the y-intercept. To find the slope, we use the formula (y2 - y1) / (x2 - x1), substituting the given points. After calculating the slope, we can plug one pair of the given coordinates into the equation y = mx + b, and solve for 'b', which gives us the y-intercept.

Answer:
3.5 miles
Step-by-step explanation:
From the question, we have the following information:
The super speedway at Daytona International Speedway is = 2.5 miles
long
The road course there is = 1.4 times as long as the super speedway.
How long is the road course?
The length of the road course is calculated as:
1.4 × length of the super speedway
1.4 × 2.5 miles
=>3.5 miles
Therefore, length of the road course I s 3.5 miles.
