Answer:
ab + cd-bd-ac = a(b-c)+d(c-b)
Step-by-step explanation:
ab+cd-bd-ac
Let us first bring the like terms together
Like terms are those terms which have same variables and same exponents also. Hence in this case we do not any like terms.
Hence we will take those two terms together which has atleast one same variable
ab and ac
cd and bd
ab-ac+cd-bd
now taking a as GCF in first two terms and d as GCF in last two terms
a(b-c)+d(c-b)
First solve for w and then graph.
-5w + 9 = 14
Now add negative 9 to both sides of the equation
-5w + 9 - 9 = 14 - 9
-5w = 5
Now divide - five from both sides
-5w / -5 = 5 / -5
w = -1
Now it is time to plot the w, which is -1, on a number line. See image that is attached for plot
Answer: 36 years
Step-by-step explanation:
Exponential equation to represent growth:-
, where A is the initial value , r is the rate of growth and t is the time period.
Given : A rare coin appreciates at a rate of 5.2% a year. If the initial value of the coin is $500.
i.e. Put A= 500 and r= 0.052 in the above formula.
The amount after t years:
Inequality for value cross $3,000 mark:
Divide both sides by 500
Taking log on both sides , we get
Hence, it will take approx 36 years to cross the $3,000 mark.

Answer:
sqrt(x)=x^1/2
Step-by-step explanation:
The root of a number is the same as writing that number to 1 over the root. In a square root, it is what number multiplied by itself (x*x), as you can see there are two, so it is that number to the 1/2 power. another example is something to the seventh power. that is calculating what number multiplied by itself 7 times would equal the nmber you are taking the root of. (x*x*x*x*x*x*x) so this would be a number to the 1/7 power.
