tensa zangetsu [6.8K]

Answer:

Step-by-step explanation:

To solve this, you need to find the unit price by dividing the cost by the amount. For Mike, divide $2 by 2 to get 1. So, Mike sells hot dogs for $1. Next, divide 2.25 by 3 to get $0.75. So, Sue sells hot dogs for $0.75.

Joe: $1.50

Mike: $1

Jen: $1.25

Sue: $0.75

So, the best deal is Sue because it is the cheapest per unit. Hope this helped!

Which of the following is not a solution to the system of linear equations below?
ra1l [238]

Answer:

<h2>B. (-15, 12)</h2>

Step-by-step explanation:

\left\{\begin{array}{ccc}5y=3x+15&\text{subtract 3x from both sides}\\6x=10y-30&\text{subtract 10y from both sides}\end{array}\right\\\left\{\begin{array}{ccc}-3x+5y=15\\6x-10y=-30&\text{divide both sides by 2}\end{array}\right\\\underline{+\left\{\begin{array}{ccc}-3x+5y=15\\3x-5y=-15\end{array}\right}\\.\qquad0=0\qquad\bold{TRUE}\\\\\bold{Infinitely\ many\ solutions}\\\\5y=3x+15\qquad\text{divide both sides by 5}\\\\y=\dfrac{3}{5}x+3\qquad(*)\\\\\text{Put the coordinates of the points to the equation (*)}

A.\ (5,\ 6)\\\\6=\dfrac{3}{5}(5)+3\\\\6=3+3\\\\6=6\qquad\bold{CORRECT}\\\\B.\ (-15,\ 12)\\\\12=\dfrac{3}{5}(-15)+3\\\\12=(3)(-3)+3\\\\12=-9+3\\\\12=-6\qquad\bold{FALSE}\\\\C.\ (0,\ 3)\\\\3=\dfrac{3}{5}(0)+3\\\\3=0+3\\\\3=3\qquad\bold{CORRECT}\\\\D.\ (-10,\ -3)\\\\-3=\dfrac{3}{5}(-10)+3\\\\-3=(3)(-2)+3\\\\-3=-6+3\\\\-3=-3\qquad\bold{CORRECT}

What is the exact distance from (-5, 1) to (3,0)? (4 points)
frez [133]

Answer:

The exact distance is √65 units

Step-by-step explanation:

To solve this problem we first have to make the difference between (-5, 1) and (3, 0)

(3 , 0) - (-5 , 1) =

3 - (-5) = 8

0 - 1 = -1

(8 , -1)

Now that we have the distance in x and r we can use Pythagoras to calculate the distance of the diagonal

a = 8

b = -1

h² = a² + b²

h² = 8² + (-1)²

h² = 64 + 1

h² = 65

h = √65

The exact distance is √65 units
