Answer:
B
Step-by-step explanation:
We want to find the equation of a line with a slope of 3 that includes the point (0, 5).
We can use the slope-intercept form, given by:

Where m is the slope and b is the y-intercept.
Notice that the given point (0, 5) is already the y-intercept. So, b = 5.
By substitution, we acquire:

Hence, our answer is B.

Answer:
B. x+60+90=180
Step-by-step explanation:
You selected the right choice yay!!
A line will always equal 180 and we are given three things that must equal 180. Also, what is on the top is the same as the bottom so x applies.
x+60+90=180
Answer:
B - yes
Step-by-step explanation:
If (n - 9) is a factor then when evaluated at n = 9, if the result is zero then it is a factor of the polynomial, that is
9³ + 9² - 84(9) - 54
= 729 + 81 - 756 - 54
= 0
Since the result is zero then (n - 9) is a factor of the polynomial
Answer:
(3 7/8, 2 3/4)
Step-by-step explanation:
To find the midpoint, the formula is (x1-x2)/2 and (y1-y2)/2. So, in this case, our x1 is 4 1/2 and our x2 is -3 1/4. Subtract x2 from x1 and you will get 7 3/4. Then, divide by 2 to get 3 7/8. This is our x-coordinate.
Our y1 is 3 3/4 and our y2 is -1 3/4. Subtract y2 from y1 to get 5 1/2. Then divide by two to get 2 3/4. This is our y-coordinate.
Now we have our x and y coordinates.
(3 7/8, 2 3/4)
