Use the elimination method to solve the system of equations. Choose the
hichkok12 [17]

Answer:

the ordered pair is (2,-1)

Step-by-step explanation:

We need to solve the system of equations using elimination method

12x - y = 25     eq(1)

9x + y = 17      eq(2)

Adding eq(1) and eq(2)

12x - y = 25

9x + y = 17

___________

21x = 42

x = 42/21

x= 2

Now, putting value of x in equation 1

12x - y = 25

12(2) -y = 25

24 -y = 25

Adding -24 on both sides

24 -y-24 = 25-24

-y = 25-24

-y = 1

Multiply both sides by -1

y = -1

the value of x = 2 and y = -1

So, the ordered pair is (2,-1)

Y = 1.6x + 48
777dan777 [17]

Answer:

Step-by-step explanation:

If the equation of height of a man is modeled by the function y = 1.6x + 48 where;

y is the height of a man

x is the shoe size

To get the approximate shoe size for a man having a height of 60 inches, we will substitute y = 60 into the formula ans solve for x as shoen;

y = 1.6x + 48

60 = 1.6x + 48

1.6x = 60-48

1.6x = 12

x = 60/1.6

x = 7.5

x = 7 1/2

Hence the approximate shoe size for a man having a height of 60 inches is 7 1/2
