Answer:
solution is (10/3 , -7/3) for y = (1/2)x - 4 and y = 2x - 9
Step-by-step explanation:
y = (1/2)x - 4
y = 2x - 9
2x - 9 = (1/2)x - 4
(3/2)x = 9 - 4
(3/2)x = 5
x = 10/3
y = 2*(10/3) - 9 = 20/3 - 9 = 20/3 - 27/3 = -7/3
solution is (10/3 , -7/3) unless you meant to write y = x - 4 and y = 2x - 9
if so then x - 4 = 2x - 9 x = 5... but this is not in your solution set.
Answer:
ok what do you want help with?
Step-by-step explanation:
$90
because if 1 body equals 30 each and she has 3 body’s add 30 3 times 30+30=60+30=90
Answer:
418.2477796 m
Step-by-step explanation:
You divide it in to a rectangle and 2 half circles (which will make a whole circle if added together) and solve them.
P= 2( L + W) - - > 2 ( 102 + 60)= 324
- Circle (has a circumference not a perimeter)
Cf= 2лr^2 - - - > 2л(30)^2=30л
324 + 30л = 418.2477796 m
