Answer:

one solution; (x, y) = (4/3, 11/3)

Step-by-step explanation:

The two lines described by the equations have different slopes, so there will be exactly one solution to the system of equations.

The slope of the line will be the coefficient of x when you solve for y. In the first equation, the slope is 2. In the second equation, you can solve for y by adding x, and dividing by 2. Then the slope of that line is found to be 1/2.

Lines with different slopes must intersect somewhere. That point of intersection is the (one) solution to the system of equations.

What basic trigonometric identity would you use to verify that (sin2x + cos2x)/cosx=secx

Oksana_A [137]

Answer:

Step-by-step explanation:

sin(2x) = 2 sin(x) cos(x) cos(2x) = cos2(x) – sin2(x) = 1 – 2 sin2(x) = 2 cos2(x) – 1. Now I am not sure if this is right but I remember another similar formula. Here is the correct formula cot x = cos x / sin x

2 ) ( sin² x + cos² x ) / cos x = sec x

1/cos x = sec x

sec x = sec x

cos² x + sin² x = 1

Solve the equation for the indicated variable S=2πrh+2πr² Solve for h

valina [46]

Answer:

Good luck :)

Step-by-step explanation:

S=2πrh+2πr ²

subtract 2πr ² from each side

S -2πr ² = 2πrh

divide by 2πr from each side

(S -2πr ² )/ 2πr = h

Jenny is selling chocolate bars it for each bar she sells she makes two dollars profit she wants to use The money she earns I’m

andre [41]

Answer:

Yes

Step-by-step explanation:

Since Jenny makes a profit of $2 for each bar of chocolate that she sells, if she sells a total of 500 chocolate bars, her profit would be:

Profit for 500 chocolate bars = profit for each chocolate bar * 500 bars

Profit for 500 chocolate bars = $2 per bar * 500 bars

Profit for 500 chocolate bars = $1000

Also she want to buy a laptop worth $998. This would be possible after selling 500 bars because $1000 > $998. After buying the laptop she would have $2 remaining ($1000 - $998)
