3 and 4. answered below
5. The point of intersection is where two lines intersect.
Step-by-step explanation:
you have -x+2y=6. finding the slope is very easy, you just have to isolate y.
2y=6+x ---> y = 3+ x/2. The slope would be 1/2 for the first one. the y intercept would be 3.
To graph, there are different ways of doing it. You can do it by finding the y intercept and x intercept, by making a chart and finding plotting points, or you can do it graphing the y intercept and doing rise over run from there.

For this question, we only need the data at the Congtin column.
So, we have:
First, we need to reduce Giraffe by 63%.
This gives:
Represent this as a ratio:
The closest to this ratio is 3:7.
This is shown by dividing the ratio by 15
i.e.
Approximate:
6u + 3u = 18
9u = 18
u = 18/9
u = 2
Answer:
3/4 cups of flour are needed.
Step-by-step explanation:
(3 2/3)/1=(2 3/4)/x
(11/3)/1=(11/4)/x cross multiply.
11x/3=11/4 cross multiply.
4*11x=3*11
44x=33
x=33/44
x=3/4
Answer:
7 < x < 34
Step-by-step explanation:
The answer must be greater than 7, else the two sides are less than or equal to the third. That triangle is impossible. The answer must also be less than 34, because then the two other sides would equal the third, making an impossible triangle.
