dimulka [17.4K]

It's a linear function: y = mx + b

We have (138; 112.96); (209; 142.78)

substitute the values of x and y to the formula of slope m:

m=\dfrac{y_2-y_1}{x_2-x_1}\\\\m=\dfrac{142.78-112.96}{209-138}=0.42

Now we have: y=0.42x+b

We must find b. Substitute the value of x and y from first pair of numbers:

112.96=0.42\cdot138+b\\\\112.96=57.96+b\ \ \ |-57.96\\\\b=55

Answer: y = 0.42x + 55

The sum of two numbers is 176. If one number is 20% more than the other number, what are the other two numbers?
Fantom [35]

Answer:

The other number is 70.4

Step-by-step explanation:

176 ÷ 2 = 88

88 - 20% = 70.4

20% of 88 is 17.6

88 + 17.6 = 105.6

105.6 + 70.4 = 176
