Answer:
She can buy 4 sets of earrings.
Step-by-step explanation:
Hi again,
We know that she wants to spend less than $25 and she already spent $9.50 on a necklace, we also know that each pair of earrings costs $3.50 so we can write an inequality...
9.5 + 3.5x < 25
( 9.5 is how much she already spent, 3.5 is the cost for every earring set, and we put a < because she wants to spend LESS than 25 not 25 or greater)
Now, solve...
9.5 + 3.5x < 25
Subtract 9.5 on both sides...
3.5x < 15.5
Divide by 3.5 on both sides...
x < 4. 43
You can't buy 4.43 sets of earrings, so the answer is simply 4. She can buy 4 sets of earrings.
Hope this helps and let me know if you need anything.

Answer:

Step-by-step explanation:
The given parametric equation is
x=2t
y= -3t
The coordinates of any point lying on this curve can be obtained by substituting the parameter value.
Given the parameter value, t=60
We have

and

Therefore the point
lie on this parametric curve.
Answer: True False True true
Step-by-step explanation:
All reals is the answer.
Since y =-9 graph is way below the absolute value graph. Meaning that y value of modulus is greater than the constant graph.
I think the equation is y=-2x+1
