x = 9.
To get there, we can divide both sides by 8, to get from 8x to x.
8x / 8 = 72 / 8.
x = 9
A, C, D, G
_____
B - the graph is of a quadratic function (apparently). It has a minimum value of -9 as shown on this graph. The maximum is +∞, which is not of interest.
E - the intercepts are (-4, 0) and (2, 0).
F - the vertex is (-1, -9). The solutions are the zeros or x-intercepts (generally), unless the question is asking specifically for the extreme value and where it is located. That is, the solutons to (x +1)^2 -9 = 0 will be -4 and 2.
Answer:
the third one (bottom left)
Step-by-step explanation:
all the others have at least one x value with multiple possible y values.
but for a function, there must be exactly 1 y value for each defined x value.
Answer: no, 3 cannot be equal to 300 because 3 is equal to 3
Step-by-step explanation:
You need a length and width for it
