Answer:
Graph 1 is not proportional
Graph 2 is proportional - y is 2 times x
Step-by-step explanation:
In graph 1, there is no x-y correlation
In graph 2, there is, when x=1, y=6
when x=2, y=12. Therefore, when x=3 y would equal 18.
Answer:
(3x + 4)
Step-by-step explanation:
9x²+27x+20 can be factored out to (3x + 4)(3x + 5)
Answer:
4/10
Step-by-step explanation:
Louise's family traveled 3/10 of the distance to her grandmother's house on Saturday.
Let us represent total distance = 1
The remaining distance left is calculated as:
1 - 3/10
Lowest common denominator = 10
= 10 - 3/10 = 7/10
They traveled 4/7 of the remaining distance on Sunday.
This is calculated as:
= 4/7 × 7/10
= 4/10
What fraction of the total distance to her grandmother's house was traveled on Sunday?
Answer:
36x + 24y = 423 (1)
41x + 38y = 585.75 (2)
x =$5.25
y = $9.75
Step-by-step explanation:
x = the number of student tickets sold
y = the number of adult tickets sold
36x + 24y = 423 (1)
41x + 38y = 585.75 (2)
Multiply (1) by 38 and (2) by 24
1368x + 912y = 16,074 (3)
984x + 912y = 14,058 (4)
Subtract to eliminate y
1,368x - 984x = 16,074 - 14,058
384x = 2,016
x = 2,016/384
x = 5.25
Substitute x = 5.25 into (1) to find y
36x + 24y = 423
36(5.25) + 24y = 423
189 + 24y = 423
24y = 423 - 189
24y = 234
y = 234/24
y = 9.75
x =$5.25
y = $9.75
