Answer:
The terms are x, -4, 3 and -5x.
The like terms are x and -5x, as well as -4 and 3.
Step-by-step explanation:
Like terms are terms that have the same variables and powers.
Answer:
g(f(x)) = 5x^2 - 15x + 36
Step-by-step explanation:
f(x) = x² – 3x + 9
g(x) = 5x – 9
(g o f)(x)
g(f(x))
x = f(x) = x^2 - 3x + 9
g(x^2 - 3x + 9)
= 5(x^2 - 3x + 9) - 9
g(f(x)) = 5x^2 - 15x + 36
Drag the tiles to the correct boxes to complete the pairs. Not all tiles will be used.
Match each equation with its solution set.
a2 − 9a + 14 = 0
a2 + 9a + 14 = 0
a2 + 3a − 10 = 0
a2 + 5a − 14 = 0
a2 − 5a − 14 = 0
Answer:
The system of equations is not independent (i.e. dependent)
Step-by-step explanation:
We see that in the system of equations
3x + 6y = 12 ............(1)
x + 2y = 4.................(2)
equation (1) is exactly the same as 3 times of equation (2).
When graphed, both lines will coincide.
Therefore the system of equations is not independent (i.e. dependent)
Answer:
circle P has a circumference of 800mm which is equal to 80cm
circle Q is 200cm
circle R is 4m which is equal to 400cm
You will get the sum of the distances by placing the figures under one measurement that is meters
And so add the figures in cm(200+400+80) and get 680
Then convert this to meters and get 6.8m
Hence your answer is C
