1. A. parallel, because when you get y by itself it is y=-2x+7, the two equations have the same slope which means they are parallel.
2. B. sometimes, in order for two lines to be parallel they have to have the same slope so, it is possible that two lines say with a slope of 3, those would be parallel BUT it doesn't always have to have a positive slope for it to be parallel like in question 1.
3. C. never, If they have the same slope they are parallel despite whatever the y-intercept is.
8x + 5.5y = 78.5 would be ur equation for this situation...where x is the number of children's tickets she bought and y is the number of adult tickets she bought
Im not very good at explaining this, but the ratio 4:5 would be saying that for every 5 people that visit a clothing store 4 are teens. or 2:4 could be for every 4 cars, 2 are white. does this help?
The basis for these changes every 10 years is because of the U.S. census which takes place every 10 years in a year with a 0 at the end, like 1990, 2000, 2010. Reapportionment is the reassigning of representatives seats in the U.S. House of Representatives to the states through a complicated mathematical formula that adjusts the amount of seats assigned to each state based on their population. Redistricting is the the division of boundaries geographically, in order to determine who is represented and who is eligible to vote for whom on local, state and federal levels.
Answer:
4x7
Step-by-step explanation:
in 4 groups of baskets their are 7 berries in those 4 baskets if you add all seven berries from the 4 baskets you will get your answer for 4x7=28 7+7+7+7=28 :)
