Set them equal together. 4x-8=2x+2. Subtract 2x on both sides. 2x-8=2. Add 8 on both sides. 2x=10. Divide 2 on both sides x=5. Check answer!!!
4(5)-8=12
2(5)+2=12
12=12
So answer is x=5!!!!
Answer:
F=7xy²
Step-by-step explanation:
Rewrite the question
4xy * F = 28x^2y^3 Divide by 4xy
Divide the 4 into the 28.
Divide the x into the x^2
Divide the y into the y^3
F = 7xy²
Answer:
110d + 80 > 1620
d > 14
Step-by-step explanation:
The amount of points from collecting diamonds can be represented by 110d, since you get 110 points for each diamond, d
Add 80 to this to represent the bonus points.
Use a greater than inequality, because you have to get more than 1620 points.
Put this all together:
110d + 80 > 1620
Then, solve for d:
110d + 80 > 1620
110d > 1540
d > 14
So, you have to collect more than 14 diamonds in less than 2 minutes in order to advance to the next level.
Answer:
Non-Homogeneous Recurrence Relation and Particular Solutions
A recurrence relation is called non-homogeneous if it is in the form. Fn=AFn−1+BFn−2+f(n) where f(n)≠0.
So,
0.2(n - 6) = 2.8
Distribute.
0.2n - 1.2 = 2.8
Add 1.2 to both sides.
0.2n = 4
Divide both sides by .2.
n = 20
Check.
0.2(20 - 6) = 2.8
Simplify inside parentheses.
0.2(14) = 2.8
Multiply.
2.8 = 2.8 This checks.
S = {2.8}
