What is the value of y in the equation 4(5y –8 –2) = 185 –15?

Answers

In an equation the Left hand side must equal the right hand side 4(5y-8-2)=185-15 20y-32-8=170 20y=170+32+8 20y=210 Therefore y=10,5 When you substitute the 10,5 and solve it on the left and side it's equal to 170 which is the answer on the right hand side

What is the equation of a line passing through the point (a, b) and having a slope of b?

Answers

Answer: $\ y=b(x-a+1)$

Step-by-step explanation:

The equation of a line passing from points (p,q) and has slope m is given by :-

$(y-q)=m(x-p)$

Given : Slope of line {m} = b

Point through which line is passing : (p,q) =(a,b)

The equation of a line passing from points (a,b) and has slope m is given by :-

$(y-b)=b(x-a)\n\n\Rightarrow\ y-b=bx-ba\n\n\Rightarrow\ y=bx-ba+b\n\n\Rightarrow\ y=b(x-a+1)$

Hello,

y-b=b(x-a)
==>y=bx-ab+b

$500 principal earning 4% compounded quarterly, after 10 yrCompound Interest Formula: $A = P(1 + (r)/(n))^(nt)$

Answers

The compound interest formula is A = P(1 + r/n)^(nt), where A is the final amount, P is the principal, r is the annual interest rate, n is the number of times the interest is compounded per year, and t is the time in years.

In this case, we can plug in the values given in the question to find the final amount earned after 10 years. The principal is $500, the annual interest rate is 4%, which is divided by 4 to get 1% per quarter, the number of times compounded per year is 4, and the time in years is 10. Plugging in these values, we get A = 500(1 + 0.01)^(4*10) = $740.60. Therefore, the final amount earned after 10 years is $740.60.
