Answer:
5x+9y≤32
Step-by-step explanation:
Let x be the number of cassette tapes you purchase.
Let y be the number of CDs you purchase.
The problem is you only have $32 to spend.
Different combinations of tapes and CDs are possible. We want an equation showing this relationship.
One cassette tape costs $5. The cost for any number of cassette tapes is $5 times the number
purchased; that's 5 times x, or 5x.
To find the cost of CDs purchased, we multiply $9 times the number of CDs, $9 times y or 9y.
The cost of the total purchase is
[the cost of the cassettes] + [the cost of the CDs] or
5x + 9y
Hope this helps!!
Answer:
y = (-5/2)x + 27
Step-by-step explanation:
Use the point slope formula y = mx + b.
Replace m with -5/2, x with -8 and y with 7:
7 = (-5/2)(8) + b. Find the y-intercept, b:
7 = -20 = b, or b = 27
The equation of this line is y = (-5/2)x + 27.
Answer:
224 miles
Step-by-step explanation:
What you would do is take the 3 hours times the 46 mph to get 138 miles.
3*46=138
Next, multiply the 2 hours by the 43 mph to get 86 miles.
2*43=86
Lastly, you're going to add the two.
138+86=224 miles.
Answer:
see below
Step-by-step explanation:
1. The inverse means take the not of both sides
If it is Saturday, then there is no school.
Inverse If it is not Saturday, then there is school.
The converse flips the then and the if
If there is no school, then it is Saturday.
2.) The first given part is the if, what will happen is the then part
If you are a freshman, then you are required to attend orientation.
3.)
Given: 3x+1=-14 Prove: x=-5
Statements Reasons
1. 3x+1=-14 Given
2. 3x=-15 Subtraction Property of equality ( since we subtract 1 from each side)
3. X=-5 Division Property ( since we divide each side by 3)
1 1/4 hours. When you add them that’s what you get.
