Alright to solve this problem you must start by distributing the -1 to everything in the parenthesis. To distribute, multiply both the m variable and the 3 by a -1.
This simplification results in:
34 = -m - 3

Next, isolate your -m. To do this, add 3 on both sides of the equal sigh to keep everything balanced.
This gives you:
37 = -m

Since you want to find the value of m and not -m, flip the sign of the value in your answer by moving the negative parenthesis to the integer rather than the variable.
Like this: -(37) = m

Then, distribute the negative to your integer value.
Your simplified equation now looks like this:
-37 = m

This leaves your final answer value for m as a -37.

I hope this is correct and helpful to you! :)

Answer:

Sample response: The negative sign outside the parentheses represents –1. Distribute the –1 to everything inside the parenthesis. Use the addition property of equality first to add 3 to both sides. Then use the division property of equality to divide both sides by -1.

Step-by-step explanation:

I just completed the test. I hope this helps you :)

Kelvin and Lewie each design surveys in order to determine the average number of people who buy food at the mall. Kelvin surveys
Lisa [10]

Answer:

Lewie Survey produces less valid result.

Step-by-step explanation:

Given:

1. Kelvin surveys every other person leaving the food area.

2. Lewie surveys every fifth person leaving the mall's main entrance.

Therefore,

Kelvin will able to produce valid result as he is surveying every person who is leaving food court.

Means,

There are high chances that would have bought food from the court.

Whereas,

Lewie is surveying every fifth person leaving the the mall's entrance.

Therefore,

Here probability to produce valid result is less as they may have not buy food or they may visited other shops.

So, Lewie survey will produce less valid result.

If q is inversely proportional to r squared and q=30 when r=3, find r when q=1.2
beks73 [17]

Answer:

r = 3

Step-by-step explanation:

q = k / r^{2}

k = qr^{2} = 1.2 x 3 x 3 = 10.8

q = 10.8/r^{2}

1.2 = 10.8/r^{2}

r = \sqrt{10.8 /1.2} = 3

In the diagram of circle A, what is the measure of ∠XYZ?<br><br> 35°<br> 70°<br> 75°<br> 140°
Mademuasel [1]

Answer:   First Option is correct.

Step-by-step explanation:

Since we have given that

Measure of arc WZ = 175°

Measure of ∠XAZ = 105°

We need to find the measure of ∠XYZ.

As we know the angle subtended at the center is the average of the measure of arc intercepted by it angle and its vertical angles.

\frac{175^\circ+\angle XYZ}{2}=105^\circ\\\\175^\circ+\angle XYZ=210^\circ\\\\\angle XYZ=210^\circ-175^\circ\\\\\angle XYZ=35^\circ

Hence, the value of  ∠XYZ is 35°.

Hence, First Option is correct.

Consider the function f(x) = 3x2 + 7x + 2. What is the value of the discriminant? –17253173 How many x-intercepts does this func
myrzilka [38]
What is the value of the discriminant?
 For this case, the discriminant will be given by
 b ^ 2 - 4 * a * c
 Where
 b = 7
 a = 3
 c = 2
 substituting
 b ^ 2 - 4 * a * c = (7) ^ 2 - 4 * (3) * (2) = 25
 Therefore the value of the discriminant is 25.
 How many x-intercepts does this function have?
 It has two intercepts with the x axis and can be found by equaling the function to zero. That is to say,
 3x2 + 7x + 2 = 0
 The results will be the interceptions with x.
 What are the number of zeros for this function?
 The number of zeros for this function is
 two real number solutions
 Because it is a quadratic function.

During a certain week, a post office sold Rs.280 worth of 14-paisas stamps. How many of these stamps did they sell?
Novosadov [1.4K]
So basically ...

You convert the rupees in paisas. One rupee is equal to one hundred paisas, so ...

280 × 100 = 28,000

And then we divide,

28,000 ÷ 14 = 2000

The post office sold 2000 stamps!

Hope this helped! :)
