we conclude that the linear equation in the graph is:
y = -2*x + 30
<h3>
How to find the equation in the graph?</h3>
We can define the variables:
- y = number of oranges.
- x = number of apples.
On the graph we can see two points:
(0, 30) and (15, 0).
Remember that a linear equation is of the form:
y = a*x + b
For the first point, we have:
30 = a*0 + b
30 = b
Then the line is:
y = a*x + 30
Now we can use the point (15, 0) to write:
0 = a*15 + 30
-30 = a*15
-30/15 = a = -2
Then we conclude that the linear equation in the graph is:
y = -2*x + 30

Answer:
To evaluate an algebraic expression, you have to substitute a number for each variable and perform the arithmetic operations. In the example above, the variable x is equal to 6 since 6 + 6 = 12. If we know the value of our variables, we can replace the variables with their values and then evaluate the expression.

Answer: I wish if could help you sorroy
Subsitute -4y for x
-4y+6y=18
2y=18
divide both sides by 2
y=9
sub back
x=-4y
x=-4(9)
x=-36
(x,y)
(9,-36)
Find the domain by finding where the function is define on the graph. the rang is the set of values that correspond with the domain.
Domain: {x/x<R}
Range:7
