Answer:
-13
Step-by-step explanation:
-12+3= -9
-9-4= -13
Hope this helps.
The formula to use is
A=p(1+(r/n))^(nt)
P= principle
R= rate
N= number of times it's compounded per year
T= time in years
Quadruple means 4 times
24000=6000(1+.035)^t
Divide by 6000
4= (1.035)^t
To bring the variable out of the power you take the log of both sides.
Log4= t Log1.035
Divide both sides by log1.035
(Log4)/(log1.035)=t
40.30=t
Given expression:
2x(x + 7)-(3x +1);
To distribute implies to spread a process equally in an expression. Often times, the distributive property is used for expressions inside parentheses;
2x(x + 7)-(3x +1)
Distribute 2x over the first parentheses;
the negative sign distributes over the second part
= (2x² + 14x) - 3x -1
= 2x² + 14x -3x -1
Add like terms;
= 2x² + 11x -1
This expression 2x² + 11x -1 is equal to the given one
Answer:
The equation of the line is x = 2
Step-by-step explanation:
* It is a coordinate geometry problem.
We need to find the equation of a line with undefined slope.
* The slope is undefined
The line passing through point (2 , 5)
* The rule to find the slope is
The slope is undefined if
That means the line passing through points have same x-coordinate
That means the line is vertical
* ∵ The line passing through point (2 , 5)
∵ The slope of the line is undefined
∴ All the points on the line have x-coordinate = 2
∴ The equation of the line is ⇒ x = 2
* The answer is x=2
