2/5 + 6/7 + 2/3....lowest common denominator is 105

42/105 + 90/105 + 70/105 = 202/105 =1 97/105 or 1.92 miles

Step-by-step explanation:

papa math will help you

x−3

=11

Step 1: Multiply both sides by 9.

x−3

=11

(

x−3

)*(9)=(11)*(9)

x−3=99

Step 2: Add 3 to both sides.

Which of the following is a valid comparison between the possible minimum and maximum values of the function y = -x2 + 4x - 8 an

Arturiano [62]

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

ElenaW [278]

Answer:

$y=-\frac{3}{2}x-2$

Step-by-step explanation:

using the y=mx+b equation, where m=slope and b=y-intercept, we can place our known slope and y-intercept to form our answer, $y=-\frac{3}{2}x-2$ :-) hope this helped!

Please help with this problem <br> thanks so much

Lunna [17]

Answer:

5/17

Step-by-step explanation:

If we do the multiplication first, we get:

$\frac{4-(12\div-12)}{13+(-8\div-2)}$

If we do the division next, we get:

$\frac{4+1}{13+4} = 5/17$
