lots of multiplying I've noticed
Your answer will be (4,0)
x = 4
y = 0
y = -2 x + 8 | y = x - 4
|
0 = -2 (4) + 8 | 0 = 4 - 4
|
0 = -8 + 8 | 0 = 0 (true)
|
0 = 0 (true) |
hope this helps
Answer:
Let David's age be x years
=> James' age = x+5 years
David + James = 89
=> x + x+5=89
=> 2x=84
=> x=84/2=42 years
David's age is 42 years
Answer:
The value of f(x) - g(x) is:
f(x) - g(x) = 2x² + 6x - 4
Step-by-step explanation:
Given
f(x) = 3x² + x - 3
g(x) = x² - 5x + 1
To determine
f(x) - g(x)
Using the formula
f(x) - g(x) = 3x² + x - 3 - ( x² - 5x + 1)
= 3x² + x - 3 - x² + 5x - 1
= 2x² + 6x - 4
Therefore, the value of f(x) - g(x) is:
f(x) - g(x) = 2x² + 6x - 4
