Answer:

x ≈ 41

Step-by-step explanation:

All the angles in a quadrilateral add together to equal 360°

So set up the equation:

a + b + c + d = 360°

Now fill in the values we know:

x + _ + 4x + 2x - 10 + 85 = 360

7x + 75 = 360

Now subtract both sides by 75:

7x + 75 - 75 = 360 - 75

7x = 285

Divide both sides by 7:

7x / 7 = 285 / 7

x = 40.714

Round:

x = 41

Now to check our answer, substitute 41 for x in the equation:

(41) + _ + 4(41) + 2(41) - 10 + 85

(41) + 164 + 82 - 10 + 85 = 362

The answer is close to 360, so we know it is correct

Answer:

x=40 and

+_ is 5

Step-by-step explanation:

Sum of the angles of any quadrilateral is 360.

4x +2x-10 +85 +x+_ = 360 combine like terms

7x + 75 = 360 subtract 75 on each side

7x = 360-75

7x = 285 divide by 7

x = 40.71

Now plug in back into equation x = 40:

4*40+ 2*40 -10 + 85 +40 + _  = 360

missing number is +5

Coordinates of P = (6, -4)

Now, Transformation occurs in Horizontal direction, so x-ccordinate will change in the transformation.

In short, Your Answer would be: Option 3) (-6, -4)

Hope this helps!

How do you solve this... 8=x-5/7
Anarel [89]
Add 5/7 on both sides.

It'll cancel out the negative 5/7, and it will make the x variable only equal to one number (Well, a mixed number.)

The graph shows the value of a certain model of car compared with its age. Which statement is false?
uranmaximum [27]
Answer: Choice B

===================================

A more in depth look

Choice A is true because the points are going downward as you read from left to right. The points aren't all on the same line but they are close to one. We can cross choice A off the list.

Choice B is false. So this is the answer. The fact that the points are close to the same line indicates that the r value is close to -1 rather than 0. If the points were randomly scattered about, or if they fell on a curve such as a parabola, then the linear correlation coefficient r would be (closer to) zero.

Choice C is true. The explanatory variable is the independent variable x. We can cross choice C off the list. 

Choice D is true. The points are fairly close to the same straight line. It's not perfect but it's good enough. We can cross choice D off the list.
