Y = -5x + 6 = -3x - 4
-3x + 5x = 6 + 4
2x = 10
x = 5
y = -5(5) + 6 = -25 + 6 = -19
Solution is (5, -19)
Mean: Add all of the numbers together, then divide by how many numbers there are. So, your mean is 40.6 (Rounded to the nearest tenth)
Median: The middle number (when they are in order). So, your median is 44.
Mode: The mode is whatever number appears the most; however, since there are no repeating numbers, there is no mode for this data set.
Range: Range is the difference between the highest and lowest values of the data set. So, your range is 55.

Answer:
Acute
Step-by-step explanation:
ANSWER: a=12 b=15
Explanation: (look at work below)
4a + 1b = 63 (eq1)
5a + 3b = 105 (eq2)
-12a + -3b = -189 (subt. eq1 from eq2)
————————-
-7a = -84
a = 12
4(12) + 1b = 63 (plug in the a value)
48 + 1b = 63
b = 15
Answer:
Step-by-step explanation:
1)4.5m+4.7=20m+47
4.5m-20m=47-4.7
-15.5m=42.2
m=-2.72
2)14+21w=7(2+3w)
41+21w=14+21w
21w-21w=14-41
3)49r+35=7(7r+35)
49r+35=49r+245
49r-49r=245-35
4)9(8h-3)=72h-27
72h-27=72h-27
72h-72h=-27+27
5)5.2+5.3t=10+15t
5.3t-15t=10-5.2
-9.7t=4.8
t=4.8/-9.7
t=0.49
6)6f+3.111=18f-33
6f-18f=-33-3.111
-12f=-36.111
f=-36.111/-12
f=3.01
