Answer:
She walks 100 m in 1 minute
Step-by-step explanation:
Here, given the equation, we want to know the distance covered in a minute
From the question, the equation is;
d = 100t
so when t is 1
d = 100 * 1 = 100 m
Answer:
D, I don't even think that's a real equation
Answer:
y = -x + 17
Step-by-step explanation:
A(-10,-3)
B(7,14)
C(5,12)
Need line CD perpendicular to AB through C.
Solution:
slope of AB, m1 = (yb-ya) / (xb-xa) = (14- -3) / (7- -10) = 17/17 = 1
Slope of CD, m2 = -1/m1 = -1 / 1 = -1
Line CD through C, using the point slope form
y-yc = m2(x-xc)
y-12 = -1 (x-5)
rearrange
y = -x + 5 + 12
y = -x + 17
Answer:
-1/2
Step-by-step explanation:
the slope of the line 2x-y=5 is 2
a perpendicular line has the negative reciprocal of the slope of the other line
hopefully this helps :)
