Try this solution:
1. according to the definition of logarithm

where a∈(0;1)∪(1;+oo) and b>0.
2. The variable is only in b, using item 1. it is possible to write: x+3>0.
⇒ x>-3.
Answer: D(f)=(-3;+oo).
Answer:
b. g(x) = 12x+10
c. x = 9/2
Step-by-step explanation:
b. g(2x+1)=6x+4
g(2x+1) = 6(2x+1)+4
g(2x+1) = 12x+6+4
g(2x+1) = 12x+10
g(x) = 12x+10
c. g(x) = 64
12x+10 = 64
12x = 54
x = 54/12
x = 9/2
Answer:
y = -2.5x +100
Step-by-step explanation:
Slope intercept form is
y = mx+b where m is the slope and b is the y intercept
We need to solve for y
25x+ 10y =1000
Subtract 25x from each side
25x-25x+10y = -25x +1000
10y = -25x+1000
Divide each side by 10
10y/10 = -25x/10 +1000/10
y = -2.5x +100
Answer:
x=15 y=22.5
Step-by-step explanation:
6x-5=85
6x=90
x=15
4y=90
y=22.5
4y makes a right angle so it is 90 degrees
