Find the solution to the system of equations.

Mathematics

N76 [4]3 years ago

Answer:

x = -2, y = 5.

Step-by-step explanation:

y=−4x−3

y=−2x+1

Because y is common to both left sides:

-4x - 3 = -2x + 1

-4x + 2x = 1 + 3

-2x = 4

x = 4/-2

x = -2.

So y = -4(-2) - 3

= 8 - 3

= 5 .

kobusy [5.1K]

Answer:

Number of 1 $ bill = 20

Number of 5 $ bill = 6

Explanation:

 Let p represent number of one dollar bolls and q represent number of five bills.

A total of 26 bills are in a cash box.

      p + q = 26    ------------------------- Equation 1

The total amount of cash in the box is $50

      p + 5q = 50    ------------------------- Equation 2

Equation 2 - Equation 1,

        p + 5q - p -q = 50 - 26

        4q = 24

          q = 6

Substituting in equation 1.

         p + 6 = 26

         p = 20

Number of 1 $ bill = 20

Number of 5 $ bill = 6

soldier1979 [14.2K]

The biking portion of the triathlon is 11.7 miles far

Step-by-step explanation:

Let us revise the relation between the two legs of a right triangle and

the hypotenuse

Hypotenuse = \sqrt{(leg_{1})^{2}+(leg_{2})^{2}}

To find the length of the hypotenuse

1. Square the length of each leg

2. Add the squares of the legs

3. Find the square root of the sum

∵ The legs of the triangle consist of a 4 mile  swim and a 11 mile run

∴ leg_{1} = 4

∴ leg_{2} = 11

∵ ( leg_{1} )² = (4)² = 16

∵ ( leg_{2} )² = (11)² = 121

∴ ( leg_{1} )² + ( leg_{2} )² = 16 + 121 = 137

∵ The hypotenuse of  the triangle is the biking portion of the  event

∵ Hypotenuse = \sqrt{(leg_{1})^{2}+(leg_{2})^{2}}

∴ Hypotenuse = \sqrt{137} = 11.7

The biking portion of the triathlon is 11.7 miles far
