Answer:
In the graph we can find two points, lets select:
(2, 15) and (4, 30)
Those are the first two points.
Now, for two pairs (x1, y1) (x2, y2)
The slope of the linear equation y = s*x + b that passes trough those points is:
s = (y2 - y1)/(x2 - x1)
So the slope for our equation is
s = (30 - 15)/(4 - 2) = 15/2
then our linear equation is
y = (15/2)*x + b
now we can find b by imposing that when x = 2, y must be 15 (for the first point we selected)
15 = (15/2)*2 + b = 15 + b
b = 15 - 15 = 0
then our equation is:
y = (15/2)*x
Where we used a division and a multiplication.
You are gonna use a^2 + b^2 = c^2 because the cities make a right triangle and you are trying to find the hypotenuse (c). C^2 ends up being 517 and the square root, your answer, is 22.7 miles
Answer:
B. (0,0)
Step-by-step explanation:
The y-intercept of the equation f(x) = 1/2x lies on the y-axis.
This means we need to set x = 0 and solve for y
1/2(0) = 0
Therefore, (0,0) is the y-intercept of this equation.
Inequalities are used to represent unequal expressions
The x value that is a solution of both inequalities is (a) 7
<h3>How to determine the correct x-value</h3>
The inequalities are given as:
4 < x and x < 40
Rewrite the inequality as:
x > 4 and x < 40
The above means that:
The x-values are greater than 4 and less than 40
From the options.
7 is greater than 4 and less than 40
Hence, the x value that is a solution of both inequalities is (a) 7
