Answer:
Step-by-step explanation:
hello :
the x-intercepts when : y=0 means : 2x²--8x+5 =0
∆ = b² -4ac a=2 and b= -8 and c= 5
∆ = (-8)² -4(2)(5) = 64-40 =24
∆ >0 this equation has two solutions so : two x-intercepts
A perpendicular slope is equal to the negative reciprocal of the given slope, which is 3/4.
The reciprocal of 3/4 is 4/3. The negative of that is -4/3.
Final answer: B

Step-by-step explanation:
Given data
It costs $35 for a membership
Monthly fee is $15
Let the number of months be x
and the total cost for x months be y

Answer:
The customer saves 5.9 - 5.5 = $0.5
when he shops at store B
Step-by-step explanation:
Stores A and B sells bananas at different prices per pound.
Bananas are being sold for $0.59 a pound at Store A and $0.55 a pound at Store B.
If a customer wants to buy 10 pounds of bananas from store A and store B,
The customer would spend 0.59 × 10 pounds of bananas = $5.9
buying from store A and
The customer would spend 0.55 × 10 pounds of bananas = $5.5
buying from store B.
The customer spends more for 10 pounds of bananas if he buys from shop A.
The customer saves 5.9 - 5.5 = $0.5
when he shops at store B
