For the system of equations between the two lines, there is only one solution as you can see from the graph.

The point of intersection of the lines is the solution, the intersection point is at:

x = 1, and y =4

(1 , 4).

A right triangle has a hypotenuse of 70 feet and a leg of 35 feet. What is the length of the other leg?

Hunter-Best [27]

We are given the two sides of the right triangle therefore we can use the pythagorean theorem to solve for the third side. This theorem states that, in a right triangle the square of the hypotenuse is equal to the sum of the square of each leg.

c² = a² + b²
70² = 35² + b²
b = √70² - 35²
b = 60.62 feet

Answer:

white chocolate chip: $17
gingerbread: $19

Step-by-step explanation:

We can let x and y represent the costs of packages of white chocolate chip and gingerbread cookie dough, respectively. Then the two sales can be represented by ...

11x +2y = 225

8x +10y = 326

There are several ways a system of equations like this can be solved. One of my favorites is to use a graphing calculator (see attached).

We can also use substitution. We see that the coefficients of y are simply related, so we can use ...

2y = 225 -11x . . . . from equation 1

8x +5(2y) = 326 . . . rearrange equation 2

8x +5(225 -11x) = 326 . . . . substitute for 2y

-47x +1125 = 326 . . . . simplify

799 = 47x . . . . . . . add 47x-326

17 = x . . . . . . . . . . . divide by 47

2y = 225 -11(17) = 38

y = 19 . . . . . . divide by 2

The package costs are ...

white chocolate chip dough: $17

gingerbread dough: $19.
