Answer:
True
Step-by-step explanation:
A number and its reciprocal have the same sign.
The cosecant is the reciprocal of the sine.
Therefore, the cosecant has the same sign as the sine.
Answer:


Step-by-step explanation:
Verify each case
case 1) 
Multiply in cross and then compare both sides

----> is true
therefore
Is a valid proportion
case 2) 
Multiply in cross and then compare both sides

----> is not true
therefore
Is not a valid proportion
case 3) 
Multiply in cross and then compare both sides

----> is not true
therefore
Is not a valid proportion
case 4) 
Multiply in cross and then compare both sides

----> is true
therefore
Is a valid proportion
case 5) 
Multiply in cross and then compare both sides

----> is not true
therefore
Is not a valid proportion
Answer:
The answer is 1…
Step-by-step explanation:
Well you can elimate a lot of fractions right off the bat just multiply everything by 60/1.
the final result will be
(240+15+40)+ (300+90-72)- (360+105+24)
Now solve
240-15+40=265
300+90-72=318
360+105+24=513
265+268-489
265+268= 11
533-513=20

Answer:

Step-by-step explanation:
<u>Goal</u>
- Find the equation of the line.
<u>Given</u>
- Coordinate points which are (4,3) and (6,2).
<u>Step</u><u> </u><u>1</u>
- Find the slope by using slope formula or rise over run.

Substitute the coordinate points in

<u>Step</u><u> </u><u>2</u>
- Rewrite the equation in slope-intercept form by substituting m = -0.5

Substitute m = -0.5

<u>Step</u><u> </u><u>3</u>
- Find the value of b by substituting any given coordinate points in the equation.
<em>Substituting</em><em> </em><em>both</em><em> </em><em>coordinate</em><em> </em><em>points</em><em> </em><em>still</em><em> </em><em>give</em><em> </em><em>the</em><em> </em><em>same</em><em> </em><em>answer</em><em>.</em><em> </em>
<u>Step</u><u> </u><u>3.</u><u>1</u>
- Substitute (4,3) in the equation.

<u>Step</u><u> </u><u>3</u><u>.</u><u>2</u>
- Substitute (6,2) in the equation.

<u>Step</u><u> </u><u>4</u>
- Rewrite the equation again by substituting the value of b.

Substitute b = 5 in the equation.

Hence, the equation is y = -0.5x + 5
Answer:
9x² + y² + 64 - 6xy - 16y - 48x
= 9x² - 6xy - 48x + y² - 16y + 64
= 9x² - 6x(y - 8) + y² - 2.8y + 8²
= (3x)² - 6x(y - 8) + (y - 8)²
= [3x - (y - 8)]²
= (3x - y + 8)²
