a f(a) is the function f(x) where x is replaced by a.
So we have
(3x^2 + x + 3 - (3a^2 + a + 3)) / ( x - a)
= (3x^2 - 3a^2 + x - a) / (x = a) Answer
b (3(x + h)^2 + x + h + 3 - (3x^2 + x + 3)) / h
= (3x^2 + 6xh + 3h^2 + x + h - 3x^2 - x - 3) ) / h
= (6xh + h + 3 h^2) / h
= 6x + 3h + 1 Answer
It’s the vertical axis (up and down)
the horizontal axis is the x axis (left and right)
Answer:
A) 24 cm²
Step-by-step explanation:
Area of a triangle formula:
A = 0.5bh
Given:
b = 6
h = 8
Work:
A = 0.5bh
A = 0.5(6)(8)
A = 3(8)
A = 24
Answer:
The error in the students work is
y -(-8) + 8 = -6x + 12 + 8
subtracting a negative is adding
y+8
They should subtract 8 from each side instead of adding 8 to each side
Step-by-step explanation:
We can use point slope form since we are given a point and the slope
y-y1 = m( x-x1)
y--8 = -6(x-2)
y+8 = -6(x-2)
Distribute the -6
y+8 = -6x+12
Subtract 8 from each side
y+8-8 = -6x+12-8
y = -6x+4
The error in the students work is
y -(-8) + 8 = -6x + 12 + 8
subtracting a negative is adding
y+8
They should subtract 8 from each side instead of adding 8 to each side
Answer:
The last 3, so C, D, and E.
Step-by-step explanation:
4+(14-2) = 16
See which of the following equations in the image create the value of 16 to find which ones are equivalent.
