Answer:
Step-by-step explanation:
If either the numerator or a denominator in a fraction is negative, the slope if negative. However, if both the numerator and denominator are negative, it is positive.
This polynomial would simplified as: -2y^7-2xy^4-x^8y^2-6xy (I'm assuming you meant to square the answers)
If you didn't the answer would be: -30xy-14y
But I'm pretty sure you meant to put the first one!
Answer:
A. 7:21 = 3:9
Step-by-step explanation:
7 is to 21 as 3 is to 9.
Replace the word to with colons and the word as with the equals sign
7:21 = 3:9
option 1 is not linear because it does not change by the same amount every year. It does not have a constant slope.
option 2 increases by 100 per year, constant slope, straight line, linear
-----------------------
a = A y^n
1100 =A y
1210 = Ay^2
1331 = A y^3
---------------
1210/1100 = y = 1.1
check 1331/1210 = y = 1.1 sure enough
1100 = A (1.1)
A = 1000
so
a = 1000 * 1.1^n
and the linear option 2
a = 1000+100n
You can put the numbers in for part C
10% compounded is better than 10% simple :)
Answer:
1.5
Step-by-step explanation:
The rate of change is also the slope or m. This equation is in slope intercept form which is y=mx+b. m is the rate of change. m=1.5.
