Answer:
x = 10, y = 0
Step-by-step explanation:
x + y = 10 ---> x = 10 - y
3x + 2y = 30
3 (10 - y) + 2y = 30
30 - 3y + 2y = 30
y = 0
x + 0 = 10
x = 10

Step-by-step explanation:
The graph of a non-proportional linear relationship is a line that does not cross through the origin. The graph of a proportional linear relationship does.
Given the general expression of a line: y = ax + b, where a and b are constants, if b is equal to zero, the line cross through the origin, otherwise the line inercept y-axis at value of b.
Direct variation means that y = kx, where k is a constant, then is a proportional linear relationship.
Given a cell phone company charges $19.95 per month for the first 2G, then $5 per gig over the initial 2G; the graph is a non-proportional linear relationship because the cost is never zero and the graph does not cross through the origin.
Given a cell phone company charges $29.95 per month always, then the cost is never zero and the graph does not cross through the origin.
Answer:
50 from home to school and 55 from school to home.
Step-by-step explanation:
55 is 5 more then 50.
Easy
(g o f)(-5)=g(f(-5))
first evaluate f(-5), then input the result into g(x)
f(-5)=-2(-5)-7
f(-5)=10-7
f(-5)=3
g(3)=-4(3)+6
g(3)=-12+6
g(3)=-6
(g o f)(-5)=-6
Answer:
it is 81 with doing some simple math
