Answer:

The maximum value of the equation is 1 less than the maximum value of the graph

Step-by-step explanation:

We have the equation y=-x^2+4x-8.

We can know that this graph will have a maximum value as this is a negative parabola.

In order to find the maximum value, we can use the equation x=\frac{-b}{2a}

In our given equation:

a=-1

b=4

c=-8

Now we can plug in these values to the equation

x=\frac{-4}{-2} \\\\x=2

Now we can plug the x value where the maximum occurs to find the max value of the equation

y=-(2)^2+4(2)-8\\\\y=-4+8-8\\\\y=-4

This means that the maximum of this equation is -4.

The maximum of the graph is shown to be -3

This means that the maximum value of the equation is 1 less than the maximum value of the graph

matrenka [14]
Hello!

First you find what numbers give you the same perimeter

9 + 9 + 6 + 6 = 30

5 + 5 + 8 + 8 = 26

7 + 7 + 4 + 4 = 22

6 + 6 + 8 + 8 = 28

The choice that has the same perimeter is D

The answer is D) 6 centimeters by 8 centimeters

Hope this helps!

There will be 781440 yards in 444 miles.

Given, The double number lines show the ratio of yards to miles.

A double number line with 6 equally spaced tick marks.

The line labeled yards, reads from left to right: 0, four unlabeled tick marks, 8,800. The line labeled miles, reads from left to right: 0, four unlabeled tick marks, 5.

as, 1 mile = 1760 yards

we have to find the number of yards in 444 miles.

if 1 mile = 1760 yards

on multiplying both the sides by 444, we get

444 miles = 1760 × 444

444 miles =  781440 yards.

So, there are 781440 yards in 444 miles.

Hence, there are 781440 yards in 444 miles.

Your friend says that the absolute value equation |3x+8|−9=−5 has no solution because the constant on the right side of the equa
stepladder [879]

Answer:No friend is wrong


Step-by-step explanation: you actually get two answers. After you isolate the absolute value then you take the positive and negative number of what it's set equal too.


|3x + 8| - 9 = -5 add 9 to isolate the absolute value


|3x + 8| = 4


Now set two equations because the abosulte value has two answers.

|3x + 8| = 4. and |3x + 8| = -4

Solve these by removing the absolute value bars.

3x = -4. 3x = -12

x = -4/3. X = -4
