Answer:
Betty had 45 minutes to take her test in mixed number form it is
Step-by-step explanation:
1 hour
1/4 an hour = 15 minutes
1/2 an hour is 30 minutes
1 hr 15- 30= 45
45= 3/4 of and hour remaining to test
ANSWER
The required angle is
EXPLANATION
Let the angle whose sine is
be
Then
We take the inverse sign of both sides to obtain,
We use our scientific calculator to evaluate and obtain,
Answer:
y = -5/4x - 4
Step-by-step explanation:
The equation they give you is in slope intercept form. y=mx+b. The m is the slope (-5/4). Since they want a parallel line you keep the same slope for point slope form. Point slope formula is y-y1=m(x-x1). the y1 and x1 are where you plug in the coordinates they give you.
y - 1 = -5/4x (x + 4)
y - 1 = -5/4x - 5
y = -5/4x - 4
Answer:
1/3
Step-by-step explanation:
Given two points on the line, we can find the slope using
m = (y2-y1)/(x2-x1)
= (8-7)/(6-3)
= 1/3
Answer:
2
Step-by-step explanation:
Firstly, we will need to calculate the slope of the line formed by joining the coordinates.
The slope of that line would be : m = (y2 - y1)/(x2 - x1)
= (5 - 1)/(4 - 2) = 4/2 = 2
The slope of the line joining the coordinates is 2. Since the other line is parallel to this, it simply means the slope of the second line is 2. This is because of two lines are parallel, they will have the same slope.
