Answer:
y+4 = 2(x+3)
Step-by-step explanation:
We have 2 points so we can find the slope
m = (y2-y1)/ (x2-x1)
= (2--4)/(0--3)
= (2+4)/(0+3)
= 6/3
= 2
We want to use the point slope form of the equation for a line
y-y1 = m(x-x1)
We know the slope =2 and the point (0,2)
y-2 = 2(x-0)
y-2 = 2x
We could also use the other point (-3,-4)
y--4 = 2(x--3)
y+4 = 2(x+3)
f(x) = 2^(4x)
g(x) = 2^x
(fg) = 2^4x * 2^x = 2^5x
NOTE: When multiplying two powers with same base exponents add.
(f/g)(x) = (2^4x)/(2^x) = 2^3x
NOTE: And when dividing they subtract.
Answer: a and c
//Hope it helps.
25% because 21 is a quarter of 84. And 21 times 4= 84, so 21 is 25% of 84.
Next it would be 5,5,5,5,5. Because, when you go up one in numbers you also go up one the amount.
Answer:
12
Step-by-step explanation:
x^2-2x+4 replace -2 for x
-2^2-2(-2)+4
4+4+4
12
