Step-by-step explanation:
just see if this is right
f (x)+g (x)
f (x)= -3x^2 - 1---------(1)
g(x)= 4x - 2------------(2)
(1)+(2)
-3x^2 - 1+ 4x - 2
-3x^2+4x - 3
14*sin(60°) = 7√3 ≈ 12.124 . . . is the altitude
Answer:
The y intercepts is -2
y = 1x-2
Step-by-step explanation:
The y intercept is where it crosses the y axis
The y intercepts is -2
We need to determine the slope, by using to points on the line
(0,-2) and (2,0)
m = (y2-y1)/(x2-x1)
= (0 --2)/(2-0)
= (0+2)/(2-0)
= 2/2
= 1
The equation for the line is
y = mx+b where m is the slope and b is the y intercept
y = 1x-2
P= parentheses or ()
E= exponents such as

M= multiplying
D= division
A= Addition
S= Subtraction
Another popular acronym is BEDMAS, which is pretty much the same except for division and multiplication are switched and it uses the word Brackets to describe these: ().
