Answer:
Step-by-step explanation:
Add the two equations together:
(x -y) +(x +y) = (34) +(212)
2x = 246
x = 123
y = x-34 = 89
Malik has 89 foreign stamps and 123 domestic stamps.
Answer:
(d) see attached
Step-by-step explanation:
All of the answer choices show shading above a dashed line, so we need to look a little closer at the equation of the boundary line. Written as an equation, it is ...
3x +y = 9
When you set each variable to zero and solve for the other, you find the intercepts to be ...
y = 0, x-intercept: 3x = 9 ⇒ x = 3
x = 0, y-intercept: y = 9
The only graph that has x- and y-intercepts matching these values is the one attached.
Answer:
f(x) = x^2 + 2, g(x )= -x + 1
=> (f*g)(x) = (x^2 + 2)(-x + 1)
= -x^3 + x^2 - 2x + 2
Hope this helps!
