Answer:
Step-by-step explanation:
a. (-4x^2-7) - (-4a^2-7) / x-a
b. (-4(x-h)^2-7) - (-4x^2-7) / h
since there are no numbers to plug in for the variables (a, h, x) there is no possible numerical value for the equations. The format of the equations seems familiar in the sense of limits for calculus, but I could be wrong.
Answer:
x=3 and y=-1
Step-by-step explanation:
2x-3y=9
3x+5y=4
Change equations in order to make a variable cancel out. In this case, multiply the top by -3 and the bottom by 2
-6x+9y=-27
6x+10y=8
Add the equations
19y=-19
y=-1
Plug in y=-1 into any equation
2x-3(-1)=9
2x+3=9
2x=6
x=3
Answer:
The cost of the house after 3 years is $218,545.40
Step-by-step explanation:
To find the value of this house after 3 years, multiply the cost by 1.03 three times. This will give you a 3% increase.
200,000 * 1.03 = 206,000
206,000 * 1.03 = 212,180
212,180 * 1.03 = 218,545.40
