Question 7 Which graph represents a function? X.

Mathematics
1 answer:
UkoKoshka [18]3 years ago
5 0

Answer:

bottom right graph

Step-by-step explanation:

Use the vertical line test.

Think of a vertical line moving from left to right over the graph. If in any position, the vertical intersects more than 1 point on the graph, the graph is not a function.

Only the bottom right graph passes the vertical line test, so that is the function.

the sum of two numbers is 123. when the larger number is added to 5 times the smaller, the sum is 343. find the numbers.​
vovikov84 [41]
Create a system of equations
x + y = 123
5x + y = 343

I use substitution
y = 123 - x
5x + 123 - x = 343
4x + 123 = 343
4x = 220
x = 55

Plug in
x + y = 123
55 + y = 123
y = 68

Check
5x + y = 343
5(55) + 68 = 343
275 + 68 = 343
343 = 343
