Answer:
The vectors form an obtuse angle.
Step-by-step explanation:
On a graph, -5, 1 is in the second quadrant and 8, 6 is in the first. The angle about the orgin is obtuse.
Finding the dot product between them results in a negative, which also means the angle is obtuse.
1) y=mx+b
m=slope
m=-3/7 in y=-3/7x+20
2) Since the slope is negative it is decreasing, as seen on a graph. So, the tire tread would be decreasing by the month (x).
3) y=mx+b
b=y-intercept
b=20 in y=-3/7x+20
In mathematical terms,
a number sentence that uses the equal sign to show two expressions have the same value is an equivalent equation.
You have to remember that expressions have no equal sign.
Equations have an equal sign, and it’s an expression on each side of the equal “=“ sign.
Maria has 5 more (+5) more than 6 times the number of pencils (6x) Bill has
p = pencils
6p + 5, or C, is your answer
Jamie is 3 years younger than Ray. Ray is y years old
Jamie's age is y - 3
y - 3, or B, is your answer
