Ok so in order to do these, you need to make the bases the same. Since 3^2 is 9, you can make that side of the equation look like 3^2(x+5). Now, you have 3^x=3^2(x+5). Since the bases are the same, you can drop those. Your equation will now look like x=2(x+5). All that is left to do now is solve. x=2x+10 -> -10=x
Let's say the number is represented by x.
Five times the number is 5x.
5x - 58 = -23 (Add 58 to both sides)
5x = 35 (divide both sides by 5)
x = 7
The number is 7.
Answer:
1) if we plug 2 in x, f (2)/(2-2)=100/0=undefined
2)ofcourse, when u plug -2 it makes it 0, f (-2)=0
3)the remainder being constant implies it is divisible by (x-1), 2x^2 (x-1)+4 (x-1), so ax^2=2x^2, a=2
Answer:
2 <= x < 8
Step-by-step explanation:
2 is less than or equal to x and the symbol for that is <=
the least number should also be on the left side
8 is greater than x so the symbol is <
8 is the biggest number and goes on the right
