The slope is 2.
Reason: you find the slope by dividing the difference of the y-coordinates (5 and 9) by the difference of the x coordinates (1 and 3)
9-5=4
3-1=2
4 divided by 2 =2
Answer: 147.87 calories
Step-by-step explanation:
Let the amount of calories in 238.5 grams of this cereal be represented by x.
Based on the information given, we can form an equation as:
110/177.4 = x/238.5
Cross multiply
177.4 × x = 238.5 × 110
x = (238.5 × 110) / 177.4
x = 147.87
Therefore, there are 147.87 calories in 238.5 grams of this cereal.
The property above is distribution property where we distribute x-term in the function.
Substitute both f(x) and g(x) in.
Évaluate/Combine like terms.
The function can be factored so there are two answers. (Both of them work as one of them is factored form while the other one is not.)
<u>Alternative</u>
<u>Answer</u>
- (f+g)(x) = 2x²-2x-2
- (f+g)(x) = 2(x²-x-1)
Both answers work. The second answer is in factored form.
Let me know if you have any doubts!
In order to change from 35 to 62, we have to add 27. So, the question becomes: which percentage of 35 is 27?
To answer this question, we set this simple equation
And solving for x we have
So, if you change from 35 to 62, you have an increase of about 77%
<span>The answer is reliable. A measure is assumed to have a high
reliability if it yields parallel results under steady conditions. It is the
characteristic of a set of test scores that relates to the quantity of
accidental or random error from the measurement procedure that might be rooted
in the scores. Marks that are highly reliable are precise, reproducible, and
constant from one testing time to another. To be exact, if the testing method
were to be repeated with a different group of test takers, fundamentally the
same results would be gotten. </span>
