Step-by-step explanation:
6x - 3y - 5 = 0 has slope 6/3 = 2. A perpendicular line will have slope -1/2 (since slopes of two perpendicular lines must have a product of -1), so its general form will be 3x + 6y - a = 0.
Now to find a. We know a point on the line, (4,10), and so we plug those coordinates in:
3*4 + 6*10 - a = 0
12 + 60 - a = 0
72 = a
3x + 6y - 72 = 0.
We can simplify this by dividing all numbers by 3, getting:
x + 2y - 24 = 0
use the graph of the function f shown to determine the y intercept

what two steps are necessary to put this equation into standard form? x^2-3x+27=8x-3
Answer:Add 3 to both sides and subtract 8x from both sides.Step-by-step explanation:The standard form of a quadratic equation isHere a should not be zero.Now, we have to write the given equation in this formwe have to take 8x and -3 to the left side of the equation in order to write the equation in standard form.Therefore, we have to subtract 8x and add 3 to both sides of the equation.When we do this operation, we'll get the equation in standard form which is given byHence, option is correct.Add 3 to both sides and subtract 8x from both sides.
Question
A shirt is on sale for 15 percent off the original price of x dollars. If a customer has a coupon for 5 dollars off the sale price, which of the following represents the price, in dollars, the customer will pay. excluding tax, for the shirt?
0.15x -5
O 0.85x -5
0.85(x - 5)
5-0.85x
Answer:
.85x-5
Step-by-step explanation:
If you say .15x suppose x is 1
.15*1= .15
Is 15% off 1 = .15 no its .85 thats why in these types of problems we do 100%-15%=85% and then .85*x
After deducting the discounts given to the customer, the current price the customer will pay is $(0.85x - 5).
Given parameters:
discount rate of the shirt, = 15%
original price of the shirt, = $x
additional discount on the sales price = $5
To find:
the current price the customer will payNote: the original price of the shirt = 100% of x
The current price of the shirt = original price - given discounts
The current price of the shirt = 100%x - 15%x - 5The current price of the shirt = 85%x - 5Convert the percentage to decimal by dividing it by 100
The current price of the shirt becomes 0.85x - 5Thus, after the discount the customer will pay $(0.85x - 5)

A pair of laces has a price tag of $7.00. The sales tax is 0.08 on every $1 . Which is the total price of the laces?
Question 5 of 10
The function f(x) = 2X is shifted 4 units left. The result is g(x). What is g(x)?
O A. g(x) = 2x + 4
O B. g(x) = 2X – 4
C. g(x) = 2x - 4
D. g(x) = 2x + 4
Answer:
None
See below under Remark.
Step-by-step explanation:
When you shift left, you think of moving in the negative direction. But it is not shown that way. You need to show what happens when you substitute a value in for x. Usually a graphing program helps to show which choice is right.
g(x) = f(x+4) = 2(x + 4)
None of the choices are this result, so we have to assume that the brackets were just omitted. The graph below shows what the answer given is the correct one.
Remark
Look at the graph carefully. The red line is f(x) = 2x
The blue line is g(x) = f(x-4) = 2(x - 4)
Notice that g(x) has shifted 4 units to the left. The x intercept has gone from 0,0 to (-4,0) and is so labeled.
If you have an answer with brackets around (x + 4) that's the one you choose. It needs the 2 outside the brackets.

Chang knows one side of a triangle is 13 cm. Which set of two sides is possible for the lengths of the other two
sides of this triangle?
5 cm and 8 cm
6 cm and 7 cm
• 7 cm and 2 cm
•
8 cm and 9 cm
Answer:
8cm and 9cm
Step-by-step explanation:
8cm and 9cm would be the two possible lengths for the triangle because for the triangle to work you need the other two other sides when added together needs to be greater then 13. Furthermore 5 + 8 = 13 and as 13 is the same length as the one side that is given, a triangle couldn't possibly be formed as it would just be a straight line. Moreover, this is the same with 6 + 7 which is also 13. 7 + 2 is 9 and because 9<13 a triangle couldn't possibly be formed. Finally, 8 + 9 which equals to 17 are the only two possible lengths for the triangle as 17 > 12.
