Let Sunil's present age be 4x and his wife's present age be 3x.
Answer:
a = 36 , b = 6
Step-by-step explanation:
expand the right side using FOIL and compare coefficients with like terms on left side.
(x - b)²
= x² - 2bx + b² , compare to x² - 12x + a , then
- 2b = - 12 ( divide both sides by - 2 )
b = 6
and a = b² = 6² = 36
Answer:
(0, -2)
Step-by-step explanation:
The slope equation is written as y = mx + b where m is the slope and b is the y-intercept. In this equation the slope, which is m, is -2/3 and the y-intercept is -2, which is the value of b. So the y-intercept on the graph would be found at point (0, -2)
Answer:
y=4x+.0004
Step-by-step explanation:
y=4(x+1)^-4
distribute your parenthesis
y=4x+4^-4
do your exponents
y=4x+.004
and thats as far as the problem can be simplified
hope this helps
