Follow the ax + by + c formula

ax = -3x (because both has x)
by =  y 
c =  7 (it is the constant)

-3x + y + 7 is your answer

follow the y = mx + b formula

2y = 6x + 12

2(y) = 2(x + 6)
y = x + 6 is your answer

hope this helps

vfiekz [6]
7d+3Explanation

to solve this we need to translate into math terms, so

Step 1

a) let d represents the number of dimes

let n represents the number of nickles

so

re write the expressions

\begin{gathered} number\text{ of dimes=d} \\ seven\text{ times the number of dimes = 7d} \\  \end{gathered}

The number of nickels is three more than seven times the number of dimes in other words you have to add 7 to seven times the number of dimes to obtain the number of nickles

hence

n=7d+3

therefore , the expression for the number of nickles is

7d+3

I hope this helps you

At 2063 ft, the KVLY-TV tower in North Dakota is the world’s tallest supported tower. How long would it take an object to fall f
IgorLugansk [536]
Use the equation of motion under gravity:-

s =  16t^2    where s is the distance and t = time

2063 = 16t^2

t^2 = 2063 / 16 =  128.94 s

t = sqrt 128.94  =  11. 4 seconds to the nearest tenth of a second
