Answer:
f(x) = -8(4)x
Step-by-step explanation:
The reflection of the point (x,y) across the x-axis is the point (x,-y).
Having said this, to reflect the function y=g(x) = 8(4x) over the x-axis, we just need to evaluate the equation in the point: (x,-y).
y = 8(4x) ⇒ -y = 8(4x) ⇒ y = -8(4x)
Then f(x) = -8(4x)
Attached you will find the graph of g(x) (blue) and f(x) (red),
Answer:
y=3x+1, or the second option
Step-by-step explanation:
We can see on the graph the line converges with the y-axis at (0, 1), so we can cross out the last two answers. Then we can also see that the slope is 3 on the graph and an equation that has x^2 must be a parabola. The answer is then narrowed down to the second option.
<em>Question:</em>
<em>If one basket contains five bottles each weighing 7 1/4 and the other basket has six apples each weighing 6 1/2 ounces. Which basket is heavier and by how much
?</em>
Answer:
The basket of bottles weighs more than the basket of apples by
ounces
Step-by-step explanation:
Given




Required
Determine which basket is heavy
and by how much?
First, we need the total weight of each basket.
For the bottles' basket






For the bottles' basket






By comparing both total weights, 
Hence:
The basket of bottles weighs more than the basket of apples
Calculating the difference:





Hence:
It weighs more by
ounces
Side a can be broken into to rectangles having areas:
(12-8)*4 and 8*12 so the area of side A is
A=16+96
A=112cm^2
Hello!
A function is that y only has 1 solution for every x
-3x + 8 = y is a function because it only has one y value for every x
y = x^2 + 3 is a function because it has only one y value for every x
y^2 = x is not a function because it has two y values for x = 4
Hope this helps!
