Iteru [2.4K]2 years ago

Answer:

y-30 = 3(x-1)

Step-by-step explanation:

Point-slope form of an equation is

y-y1 = m(x-x1)  where (x1,y1 ) is a point and m is the slope

We know on day 1 they exercised 30 minutes (1,30) where x is the number of days and y is the minutes.  The rate increased 3 minutes each day so m = 3

y-30 = 3(x-1)

Use the properties of logarithms to prove log, 1000 = log2 10.
Leto [7]

Given:

Consider the equation is:

\log_81000=\log_210

To prove:

\log_81000=\log_210 by using the properties of logarithms.

Solution:

We have,

\log_81000=\log_210

Taking left hand side (LHS), we get

LHS=\log_81000

LHS=\dfrac{\log 1000}{\log 8}                  \left[\because \log_ab=\dfrac{\log_x a}{\log_x b}\right]

LHS=\dfrac{\log (10)^3}{\log 2^3}

LHS=\dfrac{3\log 10}{3\log 2}                   [\because \log x^n=n\log x]

LHS=\dfrac{\log 10}{\log 2}

LHS=\log_210                    \left[\because \log_ab=\dfrac{\log_x a}{\log_x b}\right]

LHS=RHS

Hence proved.

What is the y-intercept of the graph of x - 8 = y-(-5)?
damaskus [11]

Answer:

A. -13

Step-by-step explanation:

y - (-5) is the same as y + 5

x - 8 = y + 5; you then subtract 5 from both sides

x - 13 = y

Evaluate: 5–^2 = <br> WILL MARK AS BRAINLIEST
Elanso [62]

When you have a negative exponent, you move it to the other side of the fraction to make the exponent positive.

For example:

x^{-2} or \frac{x^{-2}}{1}=\frac{1}{x^2}

\frac{1}{y^{-2}}=\frac{y^2}{1}  or  y²



So:

5^{-2}=\frac{1}{5^2}=\frac{1}{25}

Your answer is B
