Answer:

138

Step-by-step explanation:

According to PEMDAS (explains which operation you do first)

(Parentheses

Exponents

Multiplication or Division

Addition or Subtraction),

1. multiplication comes before addition

2. Even if it was 89+7x7, it would still be 7x7 first.

3. 7x7=49. Add it to 89 and you get 138

Answer:

In Section 6.1, we introduced the logarithmic functions as inverses of exponential functions and

discussed a few of their functional properties from that perspective. In this section, we explore

the algebraic properties of logarithms. Historically, these have played a huge role in the scientific

development of our society since, among other things, they were used to develop analog computing

devices called slide rules which enabled scientists and engineers to perform accurate calculations

leading to such things as space travel and the moon landing. As we shall see shortly, logs inherit

analogs of all of the properties of exponents you learned in Elementary and Intermediate Algebra.

We first extract two properties from Theorem 6.2 to remind us of the definition of a logarithm as

the inverse of an exponential function.

Step-by-step explanation:

const2013 [10]

Answer:

Step-by-step explanation:

60

%

discount given in total, so only  

40

%

is paid.

Explanation:

So here we need to make a two-step changing factor.

This means that we first take  

0.5

(something decreasing by  

50

%

) times  

0.8

(something decreased by  

20

%

) which is  

0.4

(something decreased by  

60

%

The table shows the linear relationship in a tank and time.
cluponka [151]
y = mx + b

y = slope (x) + y - intercept

To find the slope we need to find out how much the x's and y's increase or decrease...

To find the y - intercept if any, simply​ look for coordinates ( 0 , y ) or 0 and a #.

~~

In this case, as time passes, the water level decreases therefore we have a negative slope.

Time is our x and amount (ft) is our y.

On the x side it increases by 2

On the y side it decreases by 10

Now do y over x ==> 10 over 2 and get 5 ==> m

-5 is our slope and 50 is our y - intercept

~~

The "rate of change" is another word for slope.

Well, slope is - 5ft is our slope.

y = - 5x + 50

~~

I hope that helps you out!!

Any more questions, please feel free to ask me and I will gladly help you out!!
