Answer:

Domain:

{−4,10,−8}

Range:

{4,2,−6,−9}

Step-by-step explanation:

(The "Domain" is the set of all the values of x.) (The "Range" is the set of all the values of y.)

If you look at the X- values and then look at the Y-Values. That how you find Domain & Range in Math.

(1) The value of x is 25

(2) The measure of ∠CBD is 60°

Explanation:

(1) The given two angles are vertical angles. Since, vertical angles are equal, we can add the two angles to determine the value of x.

Thus, we have,

5x+15=6x-10

Subtracting 5x from both sides, we have

15=x-10

Adding 10 to both sides , we have,

25=x

Thus, the value of x is 25.

(2) It is given that the measure of ∠ABC = (x+7)° and ∠CBD = (2x+14)°

Since, these two angles are supplementary angles and supplementary angles add upto 90°

Thus, we have,

2x+14+x+7=90

Simplifying, we get,

3x+21=90

       3x=69

         x=23

Thus, substituting the value of x in ∠CBD = (2x+14)° to determine its value.

2x+14=2(23)+14=46+14=60

Thus, the measure of ∠CBD is 60°

I need help with all 4 of these . And I do need to show work for all of them
malfutka [58]

Answer:


Step-by-step explanation:

11) Profit = Selling price - purchase price - other expenses

= (2000*7)-12780-26=1194

12)  Profit = Selling price - purchase price - other expenses

=52.25(550)-28275-32=430.50=430(after rounding off)

13) Annual interest on bond

=INterest rate on face value of bond for 1 year

=2000(6%)=120

14)Cost of bond

= quoted value (rate)

=3500(80.5)

=2817.50

15) Cost of bond

= quoted value (rate)

=4250(83.5)

=3548.75
