Equation is: 200x + 250y = 3800
Put x = 0
then 250y = 3800
y = 3800 / 250
y = 15.2
Now, Put y = 0
200x = 3800
x = 3800/200
x = 19
So, the coordinates are: (19, 0) & (0, 15.2)
We will mark those coordinates & draw the line from origin. Graph is done

Answer:
False
Step-by-step explanation:
An obtuse angle is an angle greater than 90 and smaller than 180.
Both 120 and 135 are obtuse angles.
But they are not congruent.
Answer:
f(-4) = -1
f(-1) = -4
f(1) = 4
Step-by-step explanation:
We need to find the y value for the x values
f(-4) means find the y value for x= -4
f(-4) = -1
f(-1) = -4
f(1) = 4
Using a proportional relationship, we have that:
- a) The constant of proportionality is of 0.625, hence the equation is:
.
- b) The distance of two cities that are 5 miles apart is of 8 kilometers.
- c) When they are 200 kilometers apart, we have that the distance in miles is of
.
<h3>What is a proportional relationship?</h3>
- A <em>proportional relationship</em> is a function in which the <u>output variable is given by the input variable multiplied by a constant of proportionality</u>, that is:.

- In which k is the constant of proportionality.
Item a:
From the graph, when x = 8, y = 5, hence:




The constant of proportionality is of 0.625, hence the equation is:
.
Item b:
From the graph, when y = 5, x = 8, hence:
- The distance of two cities that are 5 miles apart is of 8 kilometers.
Item c:
When they are 200 kilometers apart, we have that the distance in miles is of
.
