Answer:

The correct option is 3.

Step-by-step explanation:

The given inequality is

x+3.8>-10.02

We need to find the solution set for given inequality.

Subtract 3.8 from both sides.

x+3.8-3.8>-10.02-3.8

x>-13.82

The value of x is all real number greater than -13.82.

The set builder form of solution set is

{x | x∈R, x > -13.82}

Therefore the correct option is 3.

Just help me out with this polynomial i need help <br> { -m^{2} + 6} + { -4m^{2} + 7m + 2} =
PolarNik [594]

Answer:

-5m^2+7m+8

Step-by-step explanation:

Here, we add up two polynomials shown.

The polynomials are:

[-m^2 + 6]+[-4m^2 +7m + 2]

In order to add up the 2 polynomials shown, we have to see the "like terms" and add them up.

We add up the "m^2" terms and the constant (number) terms. There is one term with "m", so we leave it like that. Let's add up. Shown below:\

[-m^2 + 6]+[-4m^2 +7m + 2]\\=-m^2-4m^2+6+2+7m\\=-5m^2+7m+8

This is the sum of the 2 polynomials shown:  -5m^2+7m+8

Find the value of X. Then find the measure of each labeled angle.
wariber [46]
Both angles WILL have the same measure.

So,

3x-10= x+40 (you have to set the equations equal to one another)


Now, add 10 to both sides.

3x=x+50

Subtract x on both sides.

2x=50

Divide both sides by 2.

x=25

Now, plug in x.

(25 +40)= 65

(3(25)-10)= 65

x equals 25 and both angles are equal to 65. Or "B".

I hope this helps!

Write an equation of the line passing through the point A(2, 0) that is parallel to the line y = 3x−5 .
sammy [17]
Hello,

In order for lines to be parallel to each other, they need to have the same slope. So, let's plug in the points and slope for point-slope form.

The equation for point-slope form is: y-y1 = m (x-x1)

Let's plug in the points into the equation. 
y-5 = m (x-0), and then let's plug in the slope for "m" : y-5 = 3 (x-0).

After plugging the numbers in, the equation is simplified to y-5 = 3 (x-0). Then distribute the 3 to the parenthesis. y-5 = 3x. To get y by itself, you need to add 5 to both sides. After that, the equation parallel to that equation is: y = 3x + 5.

Hope this helps! =)

10. A map uses the scale of Zof an inch to represent 3
galben [10]

Answer:

  • 6.25 in

Step-by-step explanation:

<em>Note. It should read 3/4 of an inch.</em>

  • 3/4 in = 3 miles
  • x in  = 25 miles

<u>Cross multiply and solve for x:</u>

  • x = 25/3*3/4
  • x = 6.25 in
