Answer:
y = 0.25x - 5
Step-by-step explanation:
Given line is 4x + y = 3
or y = -4x + 3
Comparing this with slope-intercept form y = mx + c :
slope of this line is -4
Product of slopes of perpendicular lines = -1
⇒ slope of a line perpendicular to this is 
= 
= 0.25
This line also passes through the point (-4,-6)
The equation of a line having slope m and passing through a point (h,k) is
y - k = m(x - h)
⇒ equation of line perpendicular to given line is y - (-6) = 0.25×{x - (-4)}
⇒ y + 6 = 0.25×(x + 4)
⇒ y + 6 = 0.25x + 1
⇒ <u>y = 0.25x - 5</u>
This is in the slope-intercept form y = mx + c with slope m = 0.25 and y-intercept (0,-5)
Answer:
50+(7d*13)+80+(9d*27)
Step-by-step explanation:
So, there are 13 food booths and each food booth is $50 plus $7 per day.
There are 27 game booths and each game booth is $80 plus $9 per day.
Lets make a short equation for each of the booths.
50+(7d*13)
80+(9d*27)
Lets combine both of the sentences.
50+(7d*13)+80+(9d*27)
So, my expression would be 50+(7d*13)+80+(9d*27).

Answer: Third option.
Step-by-step explanation:
According to the information given in the exercise, you can find an approximation of the the total cost in dollars of raising a child in the United States ( from birth to 17 years) given a household's annual income, with the following equation:
Where "x" represents the household's annual income in dollars.
Therefore, if the annual income is $62,500; you can identify that:
Then, in order to calculat the approximated cost to raise a child in a household with that annual income given in the exercise, you need to substitute that value of "x" into the equation and then you must evaluate in order to find the value of "y".
Through this procedure you get the following result:
