Enter the ordered pair that is the solution to the system of equations graphed below please :]
1 answer:
Hello!
Since (1, -2) is the point of intersection, then it is the solution to the system of equations. Let's test our answer to see if it's correct:
But that's only for the first one, let's test for the second one:
This is how we know that (1, -2) is the solution to the system of equations. Hope I helped! :3

Given mapping is a function.
Domain:
Range:
Step-by-step explanation:
By observing Marco's mapping diagram we can see that every value in time is mapped to only one value in the cost. This means that there will be no repetition or same output to two different outputs so given mapping is a function.
<u>Domain:</u>
Domain is the set of all inputs of a function. Here time is input so domain of function is:
<u>Range:</u>
Range is the set of all outputs of the function on domain so the range of the given function is:
Hence,

Answer:
x-intercept ⇨ -1/3
y-intercept ⇨ 1
Step-by-step explanation:
⟺ Finding the x-intercept, substitute y = 0
Move 1 to subtract the another side.
Then move 3 to divide -1, leaving only x as a subject since we want to find the x-intercept.
#
⟺ Finding the y-intercept, substitute x = 0
#
Tips:
Here's the tips about finding the intercepts of the graph.
⟺ For x-intercept, It's like solving an equation to find the x-term.
⟺ For y-intercept, It's like using the constant to answer.
As for y = mx+b where m = slope and b = y-intercept.
For a linear function, It's not necessary to substitute x = 0 just to find y-intercept as we can answer the constant as our y-intercept.
