Answer:

$2.66

Step-by-step explanation:

Step 1: Multiply the $5 to the family of 3

5 \times 3 = 15

That's what they would have paid if they did not have a coupon. Now they have a coupon and only pay $7.

Step 2: Subtract what they paid from the result

15 - 7 = 8

Now we have found how much they save altogether. To find how much they saved each;

Step 3: Divide the result found in step 2 by the family of 3

8 \div 3 = 2.66666\dots

Each person saves approximately $2.66

8 is (7+4)/(7+4+5+9) = 11/25 = 0.44

9 is 5/(5+7) = 5/12 = 0.417 so I'm sorry I can't help with that one

Find the slope of the line that passes through the pair of points
love history [14]

Answer:

\frac{5,805}{2812}

Step-by-step explanation:

To find the slope from two points you can use the following formula:

m = \frac{y -y_{1} }{x -x_{1} }

Now substitute the two sets of points (\frac{7}{20}, \frac{5}{19} ) and (\frac{5}{9}, \frac{11}{16})

Substitute the values like this:

y = \frac{5}{19}, y_{1} = \frac{11}{16}, x = \frac{7}{20} and x_{1} =\frac{5}{9}

Now you will need to simplify the following expression:

m = \frac{\frac{5}{19} -\frac{11}{16} }{\frac{7}{20}-\frac{5}{9} }

Make sure that denominators are the same before substracting:

m = \frac{\frac{-129}{304} }{\frac{-37}{180} }

when you divide with a fractional number you only need to flip the second fraction over (find its reciprocal). Then just multiply:

m = (\frac{-129}{304} })({\frac{-180}{37} } ) = \frac{5805}{2812}

elixir [45]

Answer:

r = 3

Step-by-step explanation:

x^2 + 6x + y^2 - 8y = - 16

Take half the linear term and square it.

x^2 + 6x + (3)^2 + y^2 - 8y + (-4)^2 = - 16

Add the squared amounts to the right.

x^2 + 6x + 9 + y^2 - 8y + 16 = - 16 + 9 + 16  

Combine on the right.

x^2 + 6x + 9 + y^2 - 8y + 16 = 9

Represent the 2 quadratics as perfect squares.

(x + 3)^2 + y - 4)^2 = 9

The radius is the square root of 9 which is 3

What is the constant of the expression? 5x−2y+2.4
Leno4ka [110]
The correct answer is the 2.4

The constant in an equation is the number(s) that don't have variables.

This is because variables can change the number they are attached to, making them not constant.

Hope this helps!
