Answer:
x = 1.153846153846154
y = -1.923076923076923
Step-by-step explanation:
Multiply 7x - y = 12 by -4 and then add it to 2x - 4y = 10
2x - 4y = 10
+(-4( 7x - y = 12))
-26x = -30
x = 1.153846153846154
Then plug in x to get y.
2(1.153846153846154) - 4y = 10
2.307692307692308 - 4y = 10
-2.307692307692308 -2.307692307692308
-4y = 7.692307692307692
y = -1.923076923076923
<u>Answer:</u>
60 out of 250 children will prefer organized sports.
<u>Step-by-step explanation:</u>
We are given the results of a random survey of children between the ages of 13 and 18 about their favorite activity.
Based on these results, we are to find the number of children who will prefer organized sports if 250 children were asked about their favorite activity.
Children who will prefer organized sports = = 60
Answer:
y > 4x - 2
Step-by-step explanation:
The basic format of a line in slope-intercept form is,
This format undergoes no change when one implements it for the use of a two-variable inequality.
The parameter (m) represents the slope of a line, this can be found by using the formula (). Traditionally, one would use a formula to find the slope of a line that is the following, (
). However, in the given situation, one can simply count the number of boxes from one point with respect to the x-axis to another, and thus get (4).
The parameter (b) represents the point in which the graph intersects the y-axis, one can see that this point is (-2).
Since the line is dotted, one would only use the greater than symbol, not the greater than or equal-too-symbol.
Finally, since the area above the line is shaded, therefore one knows that it is (y) is greater than.
