3x+1/5y=7
Answer:
y = -15x + 35
Step-by-step explanation:
3x + 1/5y = 7
1/5y = -3x + 7
y = 5( -3x + 7)
y = -15x + 35

Im supposed to find angles for these, and I don't know on how to do that
Answer:
110
Step-by-step explanation:
They are equal to each other.
23x-5= 21x +5
2x = 10
x = 5
21(5) +5 = 110°
23(5) -5 = 110°

3 Multiple Choice Questions. Please answer..
3. Find m∠Q
4. Find m∠1
5. Find m∠3
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.
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
Hope this helped :)

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

Answer:
I think it is correct and is 1 and 2
Step-by-step explanation:
5×4^(x+1)-16^x=64
0=64+16^x-5×4¹×4^x
0=(4^x)²-2×4^x×10+10²-10²+64
0=(4^x-10)²-36
(4^x-10)²=36
4^x-10=√36
4^x=+-6+10
when positive
4^x=4²
:.x=2
when negative
