The difference of two numbers is 15.Five times the smaller is the same as 9 less than twice the larger.Find the numbers
Lana71 [14]

Answer:

small number = -3

large number = 12

Step-by-step explanation:

Suppose two numbers are x and y

smaller number = x

larger number = y

Given that,

The difference of two numbers is 15

<h2>Equation 1</h2><h3>y - x  = 15</h3>

Five times the smaller is the same as 9 less than twice the larger.

<h2>Equation 2</h2><h3>5x = 9 - 2y</h3>

Solve them

-x = 15 - y

x = y -15

put value of x in equation 2

5(y - 15) = 9 - 2y

-75 + 5y = 9 - 2y

-75 - 9 = -2y - 5y

-84 =  -7y

y = 84/7

y = 12

x = 12 - 15

x = -3

The table shows some values of a function of the form y
kherson [118]

The value of c, the constant of the function y = ax² + bx + c, exists -3.

<h3>What is an equation?</h3>

An equation exists as an expression that indicates the relationship between two or more numbers and variables.

Given that: y = ax² + bx + c

At point (4, 21)

21 = a(4²) + 4b + c .......(1)

At point (5, 32)

32 = a(5²) + 5b + c .........(2)

At points (6, 45)

45 = a(6²) + 6b + c .......(3)

Therefore, the value of a = 1, b = 2 and c = -3.

The value of c, the constant of the function y = ax² + bx + c, exists -3.
