-2(z+3)-z=-z-4(z+2)
solve for z quickly please! will give brainliest

Answers

Answer 1

Answer:

[tex] \sf z = - \dfrac{2}{3} [/tex]

Step-by-step explanation:

Solve for z:

[tex] \longrightarrow [/tex] -2(z + 3) = -z - 4(z + 2)

-4(z + 2) = -4z - 8:

[tex] \longrightarrow [/tex] -2(z + 3) = -z -4z - 8

Grouping like terms, -z - 4z - 8 = (-z - 4z) - 8:

[tex] \longrightarrow [/tex] -2(z + 3) = (-z - 4z) - 8

-z - 4z = -5z:

[tex] \longrightarrow [/tex] -2 (z + 3) = -5z - 8

Expand out terms of the left hand side:

[tex] \longrightarrow [/tex] -2z - 6 = -5 z - 8

Add 5z to both sides:

[tex] \longrightarrow [/tex] (5z - 2z) - 6 = (5z - 5z) - 8

5z - 5z = 0:

[tex] \longrightarrow [/tex] (5z - 2z) - 6 = -8

5z - 2z = 3z:

[tex] \longrightarrow [/tex] 3z - 6 = -8

Add 6 to both sides:

[tex] \longrightarrow [/tex] 3z + (6 - 6) = 6 - 8

6 - 6 = 0:

[tex] \longrightarrow [/tex] 3z = 6 - 8

6 - 8 = -2:

[tex] \longrightarrow [/tex] 3z = -2

Divide both sides of 3z = -2 by 3:

[tex] \longrightarrow [/tex] [tex] \sf \dfrac{3}{3}z = - \dfrac{2}{3} [/tex]

[tex] \sf \dfrac{3}{3} = 1 :[/tex]

[tex] \longrightarrow [/tex] [tex] \sf z = - \dfrac{2}{3} [/tex]

Answer: output = -1n + 7 or  -n + 7

n can represent any number.

Step-by-step explanation:  using the slope-intercept form y = mx + b

y is the output. x is any input.  m is the slope.  b is the constant.

Calculate the slope:  rise ÷ run  

You see all the inputs in the chart are going up by 1. This is the run +1

You see all the outputs going down by 1.   This is the rise:  -1

So the slope, m,  is rise / run . -1/1 =  -1

To find the constant, use the slope with any pair of inputs and outputs from the chart in place of y and x in the slope-intercept equation.

y = mx + b  becomes   6 = -1(1) + b . Solve for b

6 = -1 + b

6 +1 = -1 +1 + b

7 = b

Now set up the equation that answers the question using the calculated values of m and b.

y = -1(x) + 7 . We can answer the question with this equation rewritten a bit:

Output = -1n + 7

or -n + 7  as 1 is usually implied.

-n+7 this is the answer sis

The coordinates of a point on a coordinate grid are (−1, 5). The point is reflected across the x-axis to obtain a new point. The coordinates of the reflected point are (1, −5) (−1, 5) (1, 5) (−1, −5)

Answers

Answer:

I think it should be (-1,-5)

Step-by-step explanation:

On a coordinate grid, when you flip this coordinate across the x-axis, the x-axis number won't change, meaning that -1 will stay. The intial number was in the second quadrant, this means that the new number will be in the third quadrant which is made up of all negative numbers. This means that 5 will now be graphed as negative 5, making (-1,-5) the correct answer in this situation.

A 24 ounce bag of dog food sells for $7.68. What is the unit rate of the dog food?

Answers

.32 cent per once of dog food

Answer:

$0.32

Step-by-step explanation:

You are going to divide 24 into $7.68 Once you get your problem set up think will 24 go into 7 no (so add a zero above the 7) but,   it will not so take 24 into 76. How many times will 24 go into 76 well what is 24 x 3?? It is 72. So do that. Carry your 3 and put it above the 6. Than put your 72 under your 76 and subtract. that will get you 4 well 4 can't go into 24 so carry down your 8 and that will give you 48.Then think what will 24 go into to?? Well, 24 x 2 is 48 so thats it. Put your 2 above your 8. Subtract 48-48 and get 0. When you finish that you should have $0.32.

I love the earthAnd all the gifts of her so lavish hand:Sunshine and flowers, rivers and rushing winds,Thick branches swaying in a winter storm,And moonlight playing in a boat's wide wake;But more than these, and much, ah, how much more,I love the very human heart of man.Above me spreads the hot, blue mid-day sky,Far down the hillside lies the sleeping lakeLazily reflecting back the sun,And scarcely ruffled by the little breezeWhich wanders idly through the nodding ferns.The blue crest of the distant mountain, topsThe green crest of the hill on which I sit;And it is summer, glorious, deep-toned summer,The very crown of nature's changing yearWhen all her surging life is at its full.To me alone it is a time of pause,A void and silent space between two worlds,When inspiration lags, and feeling sleeps,Gathering strength for efforts yet to come.Review the lines in bold.
