Answer:
30 are present and 10 are absent
Step-by-step explanation:
75% of 40 is 30
Therefore 30 pupils are present
And 10 pupils are absent
Answer:
15
Step-by-step explanation:
the common ratio is 1/2 so you do 30(1/2)
30(1/2)=15
Answer:
The equation of a line that passes through the point (-1,5) and has a slope of -7 will be:
Step-by-step explanation:
The slope-intercept form of the line equation
where
Given
substituting m = -7 and the point (-1, 5) in the slope-intercept form of the line equation
5 = -7(-1) + b
5 = 7+b
b = 5-7
b = -2
Thus, the y-intercept is: b = -2
now substituting b = -2 and m = -7 in the slope-intercept form of the line equation
y = mx+b
y = -7x+(-2)
y = -7x-2
Therefore, the equation of a line that passes through the point (-1,5) and has a slope of -7 will be:
Answer:
Option C
Step-by-step explanation:
Given the following question:
<u>Using the process of elimination, we can find the answer:</u>
It's not option A, because in order for a table to be a linear function the change of x, and the change of y have to be constant. In this case our change in y goes through -2, to -1. Which means option A is not a linear function.
It's not option A because again in order for a table to be a linear function the change of x and the change of y have to be constant. In this case our change of x is constant but our change in y isn't.
It's not option D because in order to have a linear function, you have to be able to rewrite the function into slope intercept (y = mx + b) in this case we only have one real number which is 12, while having our x, and y variable. Which means option D isn't a function.
Which leaves option C or "4x + 3y = 12" which is your answer, because it can be rewritten in slope intercept form.
Hope this helps.
