1. Make the equation. The product of the number and 6 equals the sum of the number and 45, so the equation would be 6x = x + 45.
2. Subtract x from both sides. You'll get 6x - x = 45.
3. You can combine like-terms by subtracting 6x - x. This is the same as 6x - 1x, which is 5x. You'll get 5x = 45.
4. Divide both sides by 5 to get x = 9.
Therefore, the number is 9.
It's Irrational cause it's not a negative number a rational is. So jts a irrational
Answer:
y-intecept = (0, y -value)
x-intercept = (x-value, 0)
=> y-intecept = (0, 0.4)
=> x-intercept = (0.3, 0)
Answer:
1975------ 4.8%
1990 ------ 11.48%
1985 ------ 8.51%
Step-by-step explanation:
Given
if 0 ≤ t < 10
if 10 ≤ t ≤ 30
Where
t:=0 implies year = 1970
Solving (a): Beginning of 1975.
First, we calculate the value of t
This falls in the range: 0 ≤ t < 10
So:
Solving (b): Beginning of 1990.
This falls in the range: 10 ≤ t ≤ 30
So:
Solving (c): Beginning of 1985
This falls in the range: 10 ≤ t ≤ 30
So:
