Answer:
Qualitative
Step-by-step explanation:
When data is quantitative, it is describing a numerical amount. For example, if the data was "the amount of houses on the street that have a garage," then the data would be quantitative since it is representing an amount (the amount of houses.) For data to be qualitative, it should be representing a quality of some kind. For example, a qualitative sample of data could be, "scents of perfumes in a store," or, "flavors of ice cream in a diner." Since our initial data is representing a quality and not a numerical amount, the data is qualitative!
Answer:
1. Anything to do with the same slope but different a B (Ex. y=1/3x+1 and y=1/3x-8)
2. No solutions
Step-by-step explanation:
1. Because the two lines are <u>parallel</u>, when no intersection between two lines happens, there will need to be a change in the B but the same slope. Remember the formula for an equation is y=mx+b. The m stands for the slope. With parallel lines, slopes are the same. If lines were to never intersect, you would have to change the b to a different number so that both lines could keep going at the same time, but never intersect.
2. Remember, solutions only happen when the two lines intersect. Infinite solutions happen when the lines are the same. One solution happens when two lines only have one point where they intersect. No solutions happen when the two lines don't intersect at all. Based off the graph given, there are no intersections so, there will be no solutions.
Answer:
x = 8
y = 21
Step-by-step explanation:
(7x + 12)° and (12x - 28)° are alternate interior angles. Alternate interior angles are congruent. Therefore:
(7x + 12)° = (12x - 28)°
Solve for x
7x + 12 = 12x - 28
Collect like terms
7x - 12x = - 12 - 28
-5x = -40
Divide both sides by -5
-5x/-5 = -40/-5
x = 8
(12x - 28)° + (9y - 77)° = 180° (linear pair)
To find y, plug in the value for x = 8.
12(8) - 28 + 9y - 77 = 180
96 - 28 + 9y - 77 = 180
Combine like terms
- 9 + 9y = 180
Add 9 to both sides
-9 + 9y + 9 = 180 + 9
9y = 189
Divide both sides by 9
9y/9 = 189/9
y = 21
