Slope of equation in the form y=mx+c is the m which is 3/4
For perpendicular lines
m1*m2=-1
m2=-1/m2
=-4/3

Answer:
12
Step-by-step explanation:
Being you can multiply 2/3 by 4/4 then the fraction would be 8/12 and therefore have a common denominator with 10/12

Answer:
C
Step-by-step explanation:
Longest practice is 2 1/2 hours long
Shortest is 1 1/4 hours long
For difference, subtract 1 1/4 from 2 1/2
Convert mixed to improper fractions
(2*2+1)/2 - (1*4+1)/4
5/2 - 5/4
10/4 - 5/4 = 5/4
Change back to mixed fraction
1 1/4
Answer:
(8, 0 )
Step-by-step explanation:
under a reflection in the line y = - x
a point (x, y ) → (- y, - x ) , then
(0, - 8 ) → (8, 0 )
Answer:
x = 40 1/2
Step-by-step explanation:
The hash marks tell you the triangles are similar and the smaller one is 1/2 the size of the larger one. Then x is half the length of the corresponding segment marked 81.
x = 81/2
x = 40 1/2
___
You may have to write it as 81/2 or as 40.5. Sometimes the answer needs to be in a particular form.
