Answer:
x = 120°
y = 60°
Step-by-step explanation:
We can find x and y with the knowledge that a line is 180 degrees.
Since x, and 60° make a straight line, we know x + 60 = 180
so x must be 120°
We can use the same knowledge to solve for y. if x is 120, and 120 + y = 180, then y must be 60°
Answer: $11.25
Step-by-step explanation:
Just add how much he spent ($7.50) and how much he had left ($3.75).
Answer:
Or, 1/2.
Step-by-step explanation:
To find the slope of a line that crosses any two given points, we can use the slope formula:
Where (x₁, y₁) is our first point, and (x₂, y₂) is our second point.
We will let (6, -7) be our first point (x₁, y₁), and (4, -8) be our second point (x₂, y₂).
Substitute them into the formula. Hence:
Simplify:
Evaluate. Hence, our slope is:
Answer:
To find the distance between two points, use the distance formula.
It will be the square root of (x2-x1)squared + (y2-y1)squared.
Use (3,-4) as x1, y1. Use (5,1) as x2, y2.
We get the square root of (5-3)squared + (1- -4)squared.
That gives us the square root of 2 squared + 5 squared.
Now we have the square root of 4 + 25, = the square root of 29.
That is the distance between the two points

Answer:
12x -3
Step-by-step explanation:
To find the perimeter, we add up all the sides
2x+ 3x-2 + 2x+1 +5x-2
Combine like terms
