(1,4) because when you substitute 1 in for x and 4 for y, you get 5(1) - 7(4) or 5 - 28 which equals -23
Contrapositive are the statements in which we switch the hypothesis and the conclusion of the statement and then we take the negation of both.
Here the hypothesis is " A line is horizontal"
And the conclusion is " slope equal to zero"
In order to make the contrapositive statement we switch the hypothesis and conclusion and then take negation.
Therefore, the contrapositive statement is given by
If a line does not have zero slope, then it is not a horizontal line.
Last option is correct.
Answer:
Options a, b, c are correct.
Step-by-step explanation:
First let's see the equation that governs the statement, which is the following:
Therefore, reading options a, b, c are correct.
Since from the formula we have the correlation coefficient of two variables x and y and here it shows us the correlation between x, y and y, x is the same.
This means that the 0.4 correlation implies a moderate but positive relationship between the two variables.
that is, the highest or lowest value of one variable implies a highest or lowest value of the other variable, respectively.
A range is the amount of time from a start of the action up to the end of the action so in your question where a function is created to present the amount of text sent each month. So the best possible restriction of the range is "The range would only include positive integers"
Answer:
10 square units
Step-by-step explanation:
Because to get the area of a triangle you cut the base length in half then multiply it by the height, in this case 2.5*4 = 10 square units
