Answer:
i think its 2-/+ not sure though sorry
Step-by-step explanation:
For this case, it depends on the context of the problem.
Most of the times the negative numbers in these types of problems mean that we owe money to some person or bank.
For example, if a car costs $ 2000 and I have $ 1500 available, then I must ask for a loan at the bank:
It means that I have to pay $ 500 to the bank.
Answer:
Amount of money you must pay.
It all depends where you start from, and what route you take.
For me, if I take the shortest possible route, then it's 3,956 miles to London
and 9,809 miles to Jakarta. So for me, Jakarta is 5,853 miles farther.
But if you're starting from, say, Singapore, then London is 6,192 miles
farther away than Jakarta.
Answer:
x = 1 and vertex = (1, - 7 )
Step-by-step explanation:
Given a quadratic function in standard form
y = ax² + bx + c ( a ≠ 0 )
The the equation of the axis of symmetry which is also the x- coordinate of the vertex is
x = -
y = 4x² - 8x - 3 ← is in standard form
with a = 4, b = - 8 , then
x = - = 1
That is equation of axis of symmetry is x = 1
Substitute x = 1 into the function for y- coordinate of vertex
y = 4(1)² - 8(1) - 3 = 4 - 8 - 3 = - 7
vertex = (1, - 7 )
Answer:
The cost of one pizza is $8
Step-by-step explanation:
From the question;
- 3 pizzas + 4 sandwiches = $34
- 3 pizzas + 7 sandwiches = $41.50
We are required to determine the cost of one Pizza
- Assuming the cost of one pizza is x and the cost of one sandwich is y
Then we get the equations;
3x + 4y = $34
3x + 7y = $41.50
We can solve the equations simultaneously;
Subtracting the two equations;
3x + 4y = $34
3x + 7y = $41.50
...........................................
-3y = -$7.5
y = $2.5
To get x;
3x = $34 - 4($2.5)
3x = $24
x = $8
Therefore, the cost of one pizza is $8
