Answer:
x = 3, x = 4
Step-by-step explanation:
To find the zeros of the function, equate f(x) to zero, that is
(x - 3)(2x - 8) = 0
Equate each factor to zero and solve for x
x - 3 = 0 ⇒ x = 3 ← smaller solution
2x - 8 = 0 ⇒ 2x = 8 ⇒ x = 4 ← larger solution
to graph a LINEar equation, since it's just a straight line, recall, to draw a straight line all you need is two points.
so we can just pick two random "x" values, hmmmmm say x = 0, what's "y"?
y = 7(0)-7 => y = -7....................................... so that gives us the point (0, -7)
hmmm x = 2, what is "y"?
y = 7(2) - 7 => y = 14-7 => y = 7................. so we get the point (2, 7).
then just plot those, and run a line through them.
Answer:
She gets
Step-by-step explanation:
She gets an error message because when solving a linear equation, the coefficient of the variable is not meant to be the same on both sides of the equation because it will equal 0 in the end. In this equation, you will get 4x on both sides and then the last step will be 0= 3. This is an error.
The answer should be 16 square cm.
