Which step can you use to solve the equation m+9=-2? <br> please help !!
nexus9112 [7]

Answer:

Subtract 9 from each side of the equation.

m = – 11

Step-by-step explanation:

m + 9 = – 2

To solve the above equation, we simply subtract 9 from each side of the equation.

This is illustrated below:

m + 9 = – 2

Subtract 9 from each side of the equation

m + 9 – 9 = – 2 – 9

m + 0 = – 11

m = – 11

Therefore, the value of m is – 11

Let the graph of g be a translation 3 units up, followed by a vertical stretch by a factor of 2 and a reflection in the x-
Keith_Richards [23]

Answer:

The answer is g(x)= -6x(x-1)+3

Step-by-step explanation:

we know that f(x) is written as 3x^{2}-3x

to show that the graph is being translated up, vertically stretching, and reflecting across the x axis, we need to factor the function.

f(x)= 3x^{2}-3x \\    3x(x-1)\\

now we can incorporate the changes to this graph.

multiply 3x by 2 and -1. (2 for a stretch and -1 for a reflection).

-6x(x-1)

tack on the +3 to show a translation of 3 units up.

-6x(x-1)+3

therefore, g(x)= -6x(x-1)+3

hope this helps!

gregori [183]

Answer:

Dependent sample: The same textbook are being compared.

Step-by-step explanation:

We are given the following in the question:

A student wants to compare textbook prices for two online bookstores.

Sample 1 from bookstore A:

$115, $43, $99, $80, $119

Sample 2 from bookstore B:

$110, $40, $99, $69, $109

Dependent and independent sample:

  • Dependent samples are paired observations for same set of items.
  • Independent samples are observations made on two different sets of items.
  • If the values in one sample affect the observations in the other sample, then the samples are dependent.
  • If the values in one sample have no effect about those of the other sample, then the samples are independent.

Thus, the given sample is dependent sample as the same textbook is being compared from two different bookstore.

Solve for t.......<br><img src="https://tex.z-dn.net/?f=4%20%28t%20%2B%20%5Ccfrac%7B1%7D%7B4%7D%20%5C%3A%20%20%29%20%3D%203" id=
Bingel [31]

Answer:

t = \cfrac{1}{2}

Step-by-step explanation:

Given equation:

4(t+\cfrac{1}{4})=3

Divide both sides by 4:

t+\cfrac{1}{4}=\cfrac{3}{4}

Subtract 1/4 from both sides:

t = \cfrac{3}{4}- \cfrac{1}{4}

t = \cfrac{2}{4}

Simplify:

t = \cfrac{1}{2}
