Answer:
a= -20
Step-by-step explanation:
Although the problem gives the value of b, it's really not needed.
Opposite sides of a parallelogram are congruent, so we just need to calculate: 2a + 2c = P
Plug the given values in:
2 * 7.6 + 2 * 14.6 = 44.4 units, or choice (C).
Answer:
y = -x + 9
Step-by-step explanation:
The line that passes through the points (-2,4) and (0,6) has a slope of 1, and a y intercept of 6. The equation to the first line is y = x + 6. and perpendicular lines always have the opposite, reciprocal slope of the other line. So the slope for the second line would be -1. A line with the slope of -1 and a point of (5,4) would contain the points (5,4) , (4,5) , (3,6) , (2,7) , (1,8) , and (0,9) , which is the y intercept for the second line. So the equation for the second line would be y = -x + 9
I think it’s D or maybe just maybe it’s will have to be B
