Although the student in the example used in this question did not make
too many errors, there is a better way of working out this equation so
that you will find the correct answer. In an equation like this where
you need to get I on it's own, you need to divide everything by two to
get -w+P over 2 = l. To get to this point, to start with you would need
to do -2w+P=2l instead of P-2w=2l.
Answer:
A. 82°
B. 144°
C. 75°
D. 150°
E. 241°
F. 80°
Step-by-step explanation:
A circle is 360°
A. 360 - 278 = 82 °
B. 360 - (124 + 92) = 144 °
C. 360 - (255 + 30) = 75 °
D. 360 - (118 + 30 +62) = 150 °
E. 360 - (21 +41 + 57) = 241 °
F. 360 - (30 + 60 + 80 + 110) = 80°
Also, the 80° is congruent so it's the same on both sides.
Answer:
Step-by-step explanation:
1) Red is the parent graph. 2) Blue is the reflection across the x-axis.
3) Green is multiplied by a factor of 5/3. (Click the imaged to see full size, i think.)

Answer:
90 miles
Step-by-step explanation:
Let ori. speed = z
distance = speed × time
= z × 2
= 2z miles
distance = (z - 15) × 3
= (3z - 45)miles
2z = 3z - 45
z = 45mph
distance = 45 × 2
= 90 miles
distance = (45-15) × 3
= 90 miles
