Answer:
- 5 ≤ x < 3
Step-by-step explanation:
The lower limit has a solid circle at - 5
This means that x can equal - 5
The upper limit has an open circle at 3
This means that x cannot be equal to 3
The inequality represented by the diagram is then
- 5 ≤ x < 3
Graphically: graph your equations and look for the intersections (these are your answers).
Algebraically: set your equations into y = format (below) and plug your values into the quadratic formula.
y = ax^2 + bx + c
(example: y = 2x^2 + 5x + 6; a = 2, b = 5, c = 6)
Answer:
A
Step-by-step explanation:
Cm is a centimeter, which is one-hundredth of a meter. Or rather, one hundred centimeters is equal to one meter.
To convert cm to meters
(62.5 cm) * (1 meter/100 cm) = .625 meters
Answer:
20
Step-by-step explanation:
Substitute the given values:
A= 4
B= 3
C= 2
5(a+b)-3(b+c)
5(4+3)-3(3+2)
Add the numbers:
5(7)-3(5)
5•7 = 35 and 3•5= 15
35-15 =20
