The zeros of the quadratic function when y = 0
so (-5 , 0) and (-2 , 0)
Answer
C) x = -2 and x = -5
f(g(x)) You plug in g(x) for x
f(x) = 2x + 3
f(g(x)) = 2(g(x)) + 3
f(g(x)) = 2(4x - 5) + 3
f(g(x)) = 8x - 10 + 3
f(g(x)) = 8x - 7
g(f(x)) You plug in f(x) for x
g(x) = 4x - 5
g(f(x)) = 4(f(x)) - 5
g(f(x)) = 4(2x + 3) - 5
g(f(x)) = 8x + 12 - 5
g(f(x)) = 8x + 7
Answer:
A
Step-by-step explanation:
A scale drawing is a reduced or enlarged form in terms of dimensions of an original image / building / object
the scale drawing is usually reduced or enlarged at a constant dimension
scale of the drawing = original dimensions / dimensions of the scale drawing
a = 12 inches / 6 = 2 inches
b = 9 inches / 6 = 1.5 inches
Answer:
10.3333333 or 10 1/3
Step-by-step explanation:
first you add the parentheses and the divide 62 by the sum of the parentheses, which is 6 creating the equation 62 ÷ 6. This equation results in 10.3333333 or 10 1/3
Answer:
See below in bold.
Step-by-step explanation:
A. (x + 7)^2 + (y - 7)^2 = 10.
This is the equation of a circle.
It is NOT a function
One to many correspondence.
B. y = x^2 + 2x - 3
This is a parabola which opens upwards.
It is a function.
For 2 values of x ( except at the vertex) there is one value of y so it is
many to one correspondence.
