So the equation has to pass through (6,-1) and be perpendicular to y = -2x + 8.
The slope is -2, and to get the slope of a line perpendicular to another line you have to find the negative reciprocal of that slope. That means -2 is equal to
-2/1, and if you flip those numbers and find the opposite of that number making it positive, the slope of a line perpendicular to it is 1/2.
But the line also has to pass through (6,-1), so we have to find the y-intercept of the new line.
To do that, you multiply 6(the x) by the 1/2(the slope) and get 3. Then you subtract 3(previous answer) from -1(the y) and get -4. That means the y-intercept is -4!
All that's left is to build the equation with this information. The equation is:
y = -4 + 1/2x
Hope this helps!
The arithmetic sequence is:
The answer is:
783
Answer:
F
Step-by-step explanation:
15 miles
15(64)+42=1002 mile - Andrea (42 is added because of her head start.)
15(67)=1005 miles - Parker
Kendra would have 26 quarters and 13 dimes.
26x.25=6.5
26/2=13
13x.1=1.3
6.5+1.3=7.8
