Answer: y = -(4/3)x + 1
Step-by-step explanation:
Let's start with finding an equation of a straight line (y=mx+b) that goes through points (-2,1) and (6,7).
The slope of a line, m, is the change in y for the change in x, or Rise/Run.
This is derived from the two points.
Rise (7-1) = 6
Run (6 - (-2)) = 8
Rise/Run = 6/8 or 3/4
The line is therefore y = (3/4)x + b
Find b by using one of the two points. I'll use (-2,1), but the other would also work.
y = (3/4)x + b
1 = (3/4)(-2) + b
1 = -(6/4) + b
b = 10/4
The line becomes y = (3/4)x + 10/4
--------
A line perpendicular to this will have a slope that is the negative inverse of the original line. The negative inverse of (3/4) is -(4/3).
The perpendicular line will be:
y = -(4/3)x + b
Use point (-6,9) to find b:
y = -(4/3)x + b
9 = -(4/3)*(-6) + b
9 = (24/3) + b
b = (27/3 - 24/3) = 3/3 = 1
The line is y = -(4/3)x + 1

. Imagine you are a restaurant owner. You are trying to set the menu price for the seared scallops with rice and mango salsa. Your item food cost is $6.78 and you set your food cost percentage to 33%. What would you set the price to be on the menu? *
1 point
$16
$18
$20
$21
The price of the food on the menu will be set at $21.
Cost of food item = $6.78
Food cost percentage = 33%
Let the price on the menu be represented by x.
Therefore, based on the information given, the equation to solve the question will be:
= 33% × x = $6.78
33/100 × x = $6.78
0.33 × x = $6.78
0.33x = $6.78
x = $6.78/0.33
x = $20.54
x = $21 approximately
Therefore, the price of the food on the menu will be set at $21.

A triangle has sides with lengths of 17 inches, 20 inches, and 28 inches. Is it a right triangle?
Answer:
no
Step-by-step explanation:
Pythagoras theorem
a2 + b2 = c2
the hypotenuse side is always the longest so its 28
:
[tex]17 { }^{2} + 20 ^{2} = 28 ^{2} [/tex]
289+ 400 =784
689 = 784
so the triangle is not a right angled triangle
“To find 623, I can just take the value of 613 then either multiply it by 12 or divide it by 2.” Do you agree with her? Explain why or why not.
Step-by-step explanation:
613 and 623 are very close values.
multiplying by 12 or a division by 2 changes the starting value drastically.
so, this cannot be right.
and dividing 613 by 2 also makes it even smaller. but to get 623 we need to make it bigger.
so, therefore, even without actually calculating the numbers, the statement is proven false.

B. 240
C. 330
D. 480
Answer:
Answer: Option 330 bars of soap Step-by-step explanation: If the amount is $ 1,200 and the simple interest for a year is 10% then the amount that Mark must pay is: If each soap bar costs $ 4 then the amount of soap bars you must sell in 1 year is: The answer is the first option
Step-by-step explanation:
Answer:
330
Step-by-step explanation:
$1,200.00 + 10% = $1,320.00 or $1,200.00 + $120.00 = $1,320.00
$1,320.00 / $4.00 = 330
330 * $4.00 = $1,320.00
