Answer:
1: 11b(exponent of 2) +6b -9c
2: -11xy -9x -5x(exponent of 2)y
Step-by-step explanation:
Answer:
605.5
Step-by-step explanation:
When you do a frequency table for this question,the zigma F becomes 2 and the zigma fx becomes 1211.Because you will multiply the marks by the frequency to get the zigma fx so after getting them you add it.Which becomes 403+808=1211.the formula for finding the mean too is zigma fx/zigma f: 1211/2=605.5
Always use the inverse (opposite) operation. Ex. is 2x+4=10.
First subtract 4, and then divide by 2.
actually reverse of order of operations to solve.
Answer:
y=2x+5
Step-by-step explanation:
y=2x+b
3=2(-1)+b
3=-2+b
+2 +2
b=5
y=2x+5
Answer:the maximum number of ccf Jake can use if he wants his bill to be no more than $58.00 is $15.3
Step-by-step explanation:
Let x represent the number of ccf of water that Jake uses in a month.
Jake's water bill is $24.40 per month plus $2.20 per ccf (hundred cubic feet) of water. This means that if she uses x ccf of water in a month, her total water bill would be
24.40 + 2.2x
Therefore, the maximum number of ccf Jake can use if he wants his bill to be no more than $58.00 would be
24.40 + 2.2x ≤ 58
2.2x ≤ 58 - 24.4
2.2x ≤ 33.6
x ≤ 33.6/2.2
x ≤ 15.3
