Answer:
- y = -3/5 × -5 - 2
- y = 2 × -1 + 2
Step-by-step explanation:
#1
- y = mx + b
- m = -3/5, x = -5, b = -2, y = y
- put in correct order
#2
- (2, -1) - (5,5) = 6/3 = 2/1 = 2 (remember, y is over x. The formula is y2 - y1 / x2 - x1)
- Pick either point given (2, -1) or (5, 5)
- Plug the point in
- y = y, m = 2, x = 2, b = -1
- Put in order
Answer:
3/2
Step-by-step explanation:
The composition of transformations has you dilate the line by a factor of 1/2, then by a factor of 3. Then the line is rotated about the origin.
The scale factor of the result will be the product of the dilation factors:
(3)(1/2) = 3/2
The scale factor of the transformation is 3/2.
Answer:
y = -5x + 4.
Step-by-step explanation:
y = mx + c is the general form
- where m = the slope of the line and c is the y-value where the graph cuts the y-axis.
The graph passes through the points (0, 4) and (1, -1) so the slope
= (Y2 - y1) / (x2 - x1)
= (-1-4) / (1-0)
= -5 = m.
and c = 4.
Answer:
268.25
Step-by-step explanation:
by using the fact that one year is 365.25 days, we can subtract our 365.25 by our 97 to get 268.25, written in the equation of 365.25-97=268.25
*edit, messed up how long a year was, corrected my issue, answer & equation.
