Answer:
a) x = -3
b) y = (28/27)x -27
Step-by-step explanation:
a) College street has a slope of 0, so is a horizontal line. 2nd Ave is perpendicular, so is a vertical line, described by an equation of the form ...
x = constant
For 2nd Ave to intersect the point (-3, 1), the constant must match that x-coordinate. The equation is ...
x = -3
__
b) Since Ace Rd is perpendicular to Davidson St, its slope will be the opposite reciprocal of the slope of Davidson St. The slope of Ace Rd is ...
m = -1/(-27/28) = 28/27
Using the point-slope equation for a line, we can model Ace Rd as ...
y -y1 = m(x -x1)
y -1 = (28/27)(x -27)
y = (28/27)x -27
Answer:
72.91
Step-by-step explanation:
100% is 67.82
1% is 67.82/100 = 0.6782
100%+7.5%= 107.5%
so, multiply!
0.6782 x 107.5 = 72.9065
round it up to 72.91
That’s the same question I’m going to ask.
If <span>ZW is an altitude of △XYZ, then m</span>∠ZWY = 90°
3a + 5 + 5a + 13 = 90
8a + 18 = 90
8a = 72
a = 72/8
a = 9
<span>m∠ZWT = 3a + 5 = 3*9 + 5 = 27 + 5 = 32</span>°
