Step-by-step explanation:

Intersecting secant angles theorem: The angle between two secants is half the difference of the intersected arcs.

52 = ½ (x − 38)

x = 142

Arc angles add up to 360.

360 = 80 + 38 + z + x

z = 100

Tangent-chord theorem: The angle between a tangent and a chord is half the intercepted arc angle.

y = x/2

y = 71

Jerome is a co-owner of a small company and received 1\3 of the companies?profits this year. What were the company?s overall pro
ale4655 [162]
Jerome makes 1/3 of the whole profit. So to find the overall profit of the company, multiply his profit by 3.
If he makes $150,000 this is how you would solve:
150,000•3= $450,000

450,000 dollars is your answer.

The dot is just a multiplication sign.

The Oliver Company plans to market a new product. Based on its market studies, Oliver estimates that it can sell up to 5,500 uni
Ghella [55]
<span>For the Oliver Company to break even, the total revenue must equal the sum of the variable costs and the fixed cost. Mathematically, this can be represented as: Total revenue = 0.4*(Total revenue) + (Fixed Costs) Let the number of units sold be x. then, 7*x = 0.4*(7*x) + 6300 Thus, x = 6300/(0.6*7) = 1500 units. Thus the company will have to sell 1500 units to break even.</span>

<h3>Answer:      y - 4 = -2(x - 5)</h3>

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

Explanation:

Point slope form is

y - y1 = m(x - x1)

where m is the slope and (x1,y1) is the point the line goes through.

Parallel lines have equal slopes but different y intercepts. The given equation y = -2x-3 has a slope of -2, meaning that m = -2 is also the slope of the mystery parallel line.

-2 will go in the second box that's just to the left of the parenthesis.

The coordinates of (5, 4) will go in the other remaining boxes to finish off the equation.

We go from this

y - y1 = m(x - x1)

to this

y - 4 = -2(x - 5)

Kyle sells used cars. He is paid $14/hour plus and 8% commission on sales. What dollar amount of car sales must Kyle make to ear
Kazeer [188]
First we have to find how much Kyle earned taking to consideration only 38h at work
So 38*14$=532$ 
Now, to find commission bonus we have to 1200-532=668
Finally, we can find what dollar amount of car Kyle must sell.
We know that 668 is 8% of that number. We can use proportion and cross multiplying, so:
8% ----------- 668
100% --------x
x= \frac{100*668}{8}=8350$ - its the result.
