Answer:
Step-by-step explanation:
Find the y-intercept by setting x = 0: f(0) = 3(4)^0 = 3(1) = 3 => (0, 3)
4^x is never zero, and its graph is always above the y-axis, for both positive and negative x.
Any real number is an acceptable x-value.
Thus the domain is (- infinity, infinity) and the range is (0, infinity).
Answer:
35
Step-by-step explanation:
x+8+243/2
x+251/2
x+251/2=4x+3
cross multiply
x+251=2(4x+3)
x+251=8x+6
x-8x=6-251
-7x=-245
x=-245/-7
x=35
I guessing you want us to find out how many pints of red and white paint is used
ok let's start with this
5x+3x=48
simplify
8x=48
divide
x=6
now multiply to find how much paint
5*6=30
30 pint of red paint
3*6=18
18 pints of white paint
<em>75 = 3 x 5 x 5 or it can be written like this: 75 = 3 x 5 squared</em>
Answer:
X^2= 10x - 74 simplifies to X^2-10x+74=0
