Answer:
B = 3
Step-by-step explanation:
The answer has to be 3 because this is a 3-4-5 triangle. We can also you the Pythagorean theorem to solve for B.
a²+b²=c²
(4)²+b²=(5)²
16+b²=25
b²=9
√b=√9
b=3
Answer:
the equation of line w will be y = 1/109x + 325/109
Step-by-step explanation:
when a line is perpendicular to another line, that means their slopes are reversed signs and flipped.
so if one slope is 2/3, the perpendicular slope would be -3/2
so in this problem, line w would have 1/109 be the slope.
using this, we can substitute m as the slope and the given point in the problem as x and y and solve for b in the slope-intercept form (y = mx +b)
m = 1/109
(2,3)
y = mx + b
3 = (1/109)2 + b
3 = 2/109 + b
327/109 = 2/109 + b
325/109 = b
putting it all together, the equation of line w will be y = 1/109x + 325/109
Answer:
19
Step-by-step explanation:
3(x-4)-x=26
3x-12-x=26
2x=38
x=19
Answer:
The inverse is 1/2x +3
Step-by-step explanation:
f(x) = 2x-6
y = 2x-6
Exchange x and y
x =2y-6
Solve for y
x+6 =2y
Divide by 2
1/2x +3 = y
The inverse is 1/2x +3
Answer:
Since the division of the number of pedestrians by the number of years yields different values for each ratio, these ratios do not form a proportion.
Step-by-step explanation:
They will form a proportion if the division of the number of pedestrians by the number of years yields the same results.
20 pedestrians : 5 years
20/5 = 4 pedestrians per year.
7 pedestrians : 1 year
7/1 = 7 pedestrians per year.
Since the division of the number of pedestrians by the number of years yields different values for each ratio, these ratios do not form a proportion.
