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!!
Hello,
First of all,
C. and D. are both incorrect because they apply translations to ABC; translations will misalign ADE with ABC.
Next,
A. is incorrect because a dilation of 1/2 will place D at (0,3) from its original point of (0,2). Also, the dilation will place E at (6,0) from its original point of (4,0). The triangle ADE would be too small to map ABC.
Finally,
B. Is the correct answer because a dilation of 2 will place D at (0,4)—where B is—and will place E at (8,0), where C is.
Choice B. maps ADE onto ABC
Sorry for that much information, but I think it’s useful. XD
I think it’s 1/3 but don’t put it! I just think it is
In 75 minutes you travelled 30 kilometers, so the rate is 30/75=0.4km/minute
another way is to use the two points to find the slope: m=(30-0)/(75-0)=0.4
Answer:
y = -3x + 3
Step-by-step explanation:
Perpendicular slope: -3
y -(-3)= -3(x-2)
y+3= -3x + 6
y = -3x + 3
