Each ride has a fixed cost of 7 and a cost that increases proportionally to the distance travelled of 0.25 per mile. Therefore the total cost of the ride is:
Where "x" is the distance in miles. Marco can only spend 30 on his ride, therefore the cost must be less or equal to that value.
We can solve the linear equation by isolating the "x" variable on the left side.
Marco's travel must be shorter or equal to 92 miles.
Answer:
Option C.
Step-by-step explanation:
The given given sequence is
1, –3, 2, 5, –4, –6
We need to find the pairs of consecutive terms of the sequence and their product.
Pairs of consecutive terms | Product
1, -3 -3
-3, 2 -6
2, 5 10
5, -4 -20
-4, -6 24
Here the product of three pairs of consecutive terms is negative.
The number of variations in sign for the sequence is 3. Therefore, the correct option is C.
–2a² + 4ab – 5a – 2b + b²
Solution:
Given data:
–2a(a + b – 5) + 3(–5a + 2b) + b(6a + b – 8)
<u>To solve this expression:</u>
Multiply each number or variable into the bracket.
–2a(a + b – 5) + 3(–5a + 2b) + b(6a + b – 8)
= –2a² – 2ab + 10a – 15a + 6b + 6ab + b² – 8b
Arrange like terms together.
= –2a² – 2ab + 6ab + 10a – 15a + 6b – 8b + b²
= –2a² + 4ab – 5a – 2b + b²
Hence the solution is –2a² + 4ab – 5a – 2b + b².
C. Is the answer I believe. At least in Canada. That’s why we have the senate here. To listen to the majority while still protecting minority rights
