Answer:

See below.

Step-by-step explanation:

(a) < PMR

(b) < QMR

(d) < RMN

2. m < C = 4x - 6

= 4(25) - 6

= 100 - 6

= 94 so < C is obtuse.

3. 8x + 2 = 90

8x = 90 - 2

8x = 88

x = 11.

(a). < DBA and < DBC are right angles (90 degrees) because BD is perpendicular to AC.

(b) < DBA and < DBC are adjacent and they share the ray BD.

(d) < DBA and < DBC are supplementary

(e) 90 - 40 = 50 degrees

(f) 180 - 40 = 140 degrees.

(g) As the angles are complementary

3x + 2 + 4x + 4 = 90

7x = 90 - 2 - 4

7x = 84

x = 12.

Given f(x) = the quantity of x plus 7, divided by 5, solve for f−1(3)

Debora [2.8K]

<span>f(x) = the quantity of x plus 7, divided by 5 $f(x)= \frac{x+7}{5}$

</span>

To get the inverse of any function f(x) [ just make sure that it passes the horizontal line test] follow the steps:

- Solve for x, i.e separate x in one side and the other terms in the other side, included f(x).

- Swap x and f(x).

- The result is the inverse of the original function $f^{-1}(x)$

So that:

$5*f(x)=x+7\\~\\~\\5f(x)-7=x\\~\\~\\Swap~now\\~\\~\\f^{-1}(x)=5x-7$

and for the value of 3:

$f^{-1}(3)=5(3)-7=15-7=8$

I hope that helps!

9.) List three things vertical and horizontal lines have in common.

12345 [234]

Answer:

Horizontal lines have a slope of zero, and run parallel to the x axis. Vertical lines have a undefined slope, and run parallel to the y axis. The equation for a horizontal line equals y=c, and the equation for a vertical line equals x=c. If a horizontal line crosses a vertical line the two lines would be perpendicular to one another.

Help please I am a bit confused on this.

Anit [1.1K]

Because there are 4 inside angles the sum of the four angles must equal 360 degrees.

Add the angles to equal 360:

4x + 3x + 2x + 3x = 360

Simplify:

12x = 360

Solve for x by dividing both sides by 12:

x = 360 /12

x = 30

Now you have x, solve for each angle:

ABC = 4x = 4 x 30 = 120 degrees.

BCD = 3x = 3 x 30 = 90 degrees.

CDA = 2x = 2x 30 = 60 degrees.

DAB = 3x = 3 x 30 = 90 degrees.

C. It's important to know that a four sides figure needs the inside angles when added together need to equal 360 degrees.

Delta Company produces a single product. The cost of producing and selling a single unit of this product at the company's normal

Mariana [72]

Answer:

The company should accept the special offer because it increases income by $23,400.

Step-by-step explanation:

Giving the following information:

Variable costs:

Direct materials $1.50

Direct labor $3.00

Variable manufacturing overhead $0.50

Variable selling and administrative expenses $1.30

Total variable cost= $6.3

An order has been received from a mail-order house for 2,000 units at a special price of $18.00 per unit.

<u>Because it is a special offer and there is unused capacity, we will not take into account the fixed costs:</u>

Effect on income= number of units*unitary contribution margin

Effect on income= 2,000* (18 - 6.3)

Effect on income= $23,400 increase

The company should accept the special offer because it increases income by $23,400.
