Find the slope of the line through each pair of points (0,1) and (3,0)

Answers

Answer 1
Answer:

\bf (\stackrel{x_1}{0}~,~\stackrel{y_1}{1})\qquad(\stackrel{x_2}{3}~,~\stackrel{y_2}{0})\n\n\nslope = m\implies\cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{0-1}{3-0}\implies \cfrac{-1}{3}

Answer 2
Answer:

Use the slope formula, which is y2-y1 divided by x2-x1. (0,1) is the first pair of points, so it will be x1 and y1. (3,0) will be the 2nd pair of points, so x2 and y2. Plug in the numbers into the formula, so 0-1 divided by 3-0 is -1/3 which is the slope.

A recipe that yields 12 cups of soup calls for 28 ounces of beef broth.how many ounces of beef broth do you need to make 18 of the soup?

Answers

we know that

A recipe that yields 12 cups of soup calls for 28 ounces of beef broth

so

by proportion

Find the ounces of beef broth needed to make 18 cups of soup

(28)/(12) (ounces)/(cups) =(x)/(18) (ounces)/(cups) \n \n12*x=18*28\n \nx=18*28/12\n \nx=42\ ounces

therefore

the answer is

42\ ounces

The original photo was 11 inches wide by 14 inches high the new photo will be 132 inches wide what will be the new height

Answers

They are similar rectangles. Therefore, the side lengths are proportional:

(11)/(132)=(14)/(x)\ \ \ \ |\text{cross multiply}\n\n11x=132\cdot14\ \ \ \ |:11\n\nx=(132\cdot14)/(11)\n\nx=(12\cdot14)/(1)\n\nx=168

Answer: The new height will be equal 168 inches.

A store had a sale on art supplies. The pricep of each item was marked down 60%.
Which expression represents the new price?
A 0.4p C 1.4p
B 0.6p D 1.6p

Answers

The expression that marks the new price is choice A 0.4 p. Since we mark the prices down 60%, the customer will only be charged 40% of the p price which is 0.4 x p.  Think of a candy bar that originally costs $1 and is marked down 60% by a discount sale.  The new price is $0.40.  
100%-60%=40%=0.4
so new price is 0.4p
Answer: A=0.4p

Hey There!

Whenever you subtract, remember you have to subtract from left to right. Also remember the process of regrouping, this also means to take away from tens. So whenever a number can't subtract you simply regroup it.
