Answer: negative, positive
Step-by-step explanation:
to average 20 points in 2 games she needs a total of 20*2 = 40 points
she scored 24 so she needs 40-24 = 16 points in her second game
the question says she needs over 20 points so she should score at least 17 to be over
inequality x+24>40
Answer:
1.15
2.-13
3.13.
4.-11
5.14
6.-12
Step-by-step explanation:
Sub in -2 for x in the first equation
y = 2/3(-2) + 3
y = -4/3 + 3
y = -4/3 + 9/3
y = 5/3
check..
y = 2/3x + 3
5/3 = 2/3(-2) + 3
5/3 = -4/3 + 9/3
5/3 = 5/3 (correct)
so ur solution is : (-2,5/3)
Answer:
260m
$73.2
Step-by-step explanation:
For what amount of driving do the plans cost the same?
What the cost when the two plans cost the same?
first plan = 42 + 0.12m
second plan = 55 + 0.07m
42 + 0.12m = 55 + 0.07m
collect like terms
55 - 42 = 0.12 - 0.07m
13 = 0.05m
m = 260
42 + 0.12(260) = 73.2
