Answer:
your supposed to flip the sign for the less than or greater than sighs when dividing by a negative.
Step-by-step explanation:
-4x←20
x→-5
With the information given, we deduce that the parabola is

Reflecting a function over the x axis means to change its sign. After the reflection, the parabola becomes

And to shift down a function, you subtract the shift from the equation: the equation becomes

Similarly, the other function is reflected over the x axis (sign change) and shifted up 3 (add 3 to the equation):

In order to compute the y intercept, we simply have to evaluate the functions at x=0: for the parabola we have

For the other function, we have

Answer:
28 miles per hour
Step-by-step explanation:
133 miles/285 minutes = 133 miles/4.75 hours = 28 miles/hour
A number is a mathematical object used to count, measure, and label
The error is that both sides of the equation have a variable. So if you were to combine your like terms, then you'd leave one side without a number and if your teacher is saying there is a left over number then it will be 0
