Answer:
Hence, the following equations, when graphed, intersect at the point (4, 0):
x - y = 4 (1)
x + y = 4 (4)
Step-by-step explanation:
<em>" For the graph to intersect at the point (4,0) we mean that when y=0 , x must be equal to 4 or we could say that when x=4 then y=0".</em>
1)
x-y=4
now when y=0 then x=4.
Hence, the graph intersect at the point (4,0).
2)
-x-y=4
When y=0 in the equation then x=-4, Hence the point (4,0) does not lie on the graph of the given function.
3)
2x-y=7
When y=0 then x=7/2.
Hence the graph of the function does not intersect at the point (4,0).
4)
x+y=4
When y=0 then x=4.
Hence the graph of the given function intersect at (4,0).
5)
2x + y = 7
When y=0 then x=7/2.
Hence the graph of the function does not intersect at the point (4,0).
6)
2x + y = -7
When y=0 then x= -7/2.
Hence the graph of the function does not intersect at the point (4,0).
Answer:
A is the correct answer
please tell me if I'm wrong
Answer:
80
Step-by-step explanation:
180=(50+50)+x
180 = 100+x
x=80
Two factors that will add up to 15 are 12 and 3.
Factors are two numbers that we multiply together to get a product.
12 x 3 = 36. They add up to 15. 12 + 3 = 15.
Like fractions have the same denominator (bottom number)
e.g.
2/4 and 3/4 are like fractions because their denominators are the same.
