Answer:

the \: slope \: is \to \boxed{60}

Step-by-step explanation:

if \to C=65+60t \\  C=60t + 65 \\ but \: the \: \boxed{ c - intercept} \: is \: in \: the \: form \to \\ c = mt + b \\ hence \to \\ 60t = mt \\ m =  \frac{60t}{t}  \\ m = 60 \\  the \: slope \: is \to \boxed{60}

Steven wants to increase the number of books he reads per year. He currently reads 2 books a year. He wants to triple the number
Sladkaya [172]

Answer:

B=2\times 3^n

Step-by-step explanation:

<u>Exponential Growing </u>

Steven currently reads 2 books a year. He wants to triple the number of books read per year. The first year he should read

2*3 = 6\ books

By the second year, he should read

2*3^2 = 18\ books

By the third year, he should read

2*3^3 = 54\ books

We can clearly see there is a geometric progression of the number of books he should read for the year n. The general formula is, being B the number of books read at the year n

\boxed{B=2\times 3^n}

Round 6.7086 to the nearest thousandth
Bingel [31]

\text {Hello! Let's solve this Problem!}

\text {To round to the nearest thousandth you must underline the thousandth place}\text {(which is 8), point an arrow to 6 (in the ten-thousandth place)}

\text {If the number is 5 or more you raise the score. Meaning you add 1 to the}\text {thousandth place. If the number is 4 or lower you keep the number the same.}

\text {6 is greater than 5. So this means you add 1 to 8 and it becomes 9. Every}\text {number behind it becomes 0.}

\text {Your Answer Would Be:}

\huge\boxed {\text {6.7090 or 6.709}}

\text {Best of Luck!}

Answer:

x = 4 is the solution

Step-by-step explanation:

given  = x ( square both sides )

x + 12 = x² ( rearrange into standard form )

x² - x - 12 = 0 ← in standard form

(x - 4 )(x + 3 ) = 0 ← in factored form

equate each factor to zero and solve for x

x - 4 = 0 ⇒ x = 4

x + 3 = 0 ⇒ x = - 3

Insert these values into the original equation, and if both sides are equal, and those are the solutions.

x = 4 :  =  = 4 = x ← correct

x = - 3 :  =  = 3 ≠ - 3 ← false

the answer is x = 4
