Answer:
A. 15, 20, and 25
Step-by-step explanation:
Note that 3-4-5 is a pythagorean triple via following:
Dividing 15, 20, and 25 by 5 nets you the pythagorean triple 3-4-5.
Answer:
His pay rate is $35.
Step-by-step explanation:
Answer:
x = 37 y = 12
Step-by-step explanation:
Let x be one number
Let y = other number
x+y = 49
x-y = 25
Add the equations together
x+y = 49
x-y = 25
---------------
2x = 74
Divide by 2
2x/2 = 74/2
x =37
x+y = 49
37+y = 49
Subtract 37 from each side
37+y-37 = 49-37
y = 12
I am going to guess you want to find a line which passes through the points (0,4) and (2,10)...
y₂-y₁ / x₂-x₁
10 - 4 / 2 - 0
6 / 2
3....slope
(0,4) .....b
y = 3x + 4
F(x)=x²+3x
f(0)=0²+3*0=0+0=0
Answer: f(0)=0
f(4)=4²+3*4=16+12=28
Answer: f(4)=28
