Y=2x -4

Answers

Answer 1

Answer:

x and y = 4

Step-by-step explanation:

Since y=x --->         x=2x-4

                              -x  -x

0=x-4            

+4   +4  ------------------> Therefore, x= 4 and y= y

Answer:

3)      (N)  angle Q = 90 degrees

4)      (E)  angle 1 = 88 degrees

5)      (G)  angle 3 = 110 degrees

Step-by-step explanation:

3) angle Q = 1/2(270-90) = 90

4) central angles equal arc angles

5) angle supplemental to angle 3 is 1/2(140), so angle 3 = 180-70 = 110

The population P, in millions, of a certain country can be modeled by the function P(t) = 3.98(1.02)t, where t is the number of years after 1990.

Answers

Answer:

7.35 Million

Step-by-step explanation:

So you already have the function and all you have to do is find the years.

p(t)=3.98(1.02)^t

I'm thinking that you should find the difference between 2021 and 1990. The answer would be 31 and just substitute that from t.

p(t)=3.98(1.02)^31

From here you would jut plug this function into your calculator and get a final answer of:

7.35 Million

The original price p of an item less a discount of 60%

Answers

Answer:

p - p(.60)

Step-by-step explanation:

to find 60% of p you turn 60% into a decimal, which is .60, next you multiply .60 by p which will give you 60% off of p,

finally you take the total which is p and subtract off the discount which is .60p, thus p-p(.60)

also... another way to solve this is that if you are getting 60% off that means you are paying 40% of the price, thus you could just multiply p(.40) to get the amount the person would actually pay
