Morgan started the year with $615 in the bank and is saving $25 per week Kendall started with $975 and is spending $15 per week
gulaghasi [49]

Answer:

Step-by-step explanation:

You can represent Morgan's scenario with the expression, 25w + 615, and you can represent Kendall's scenario with the expression, 15w + 975.  To find out when they both have the same amount of money in their accounts, you set them equal to each other and solve for w:

25w + 615 = 15w + 975

25w = 15w + 360

10w = 360

w = 36

Morgan and Kendall will have the same amount of money after 36 weeks.

Solve each inequality. Then compare the solutions.<br><br> 3x +4&gt; 16<br> - 2x + 19&lt; 11
Makovka662 [10]

Answer:

3x + 4 > 16 \\ 3x > 16 - 4 \\  \frac{3x}{3}  >  \frac{12}{3}  \\ x > 4 \\  \\  - 2x + 19 < 11 \\  - 2x < 11 - 19 \\  - 2x <  - 8 \\  \frac{ - 2x}{ - 2}  >   \frac{ - 8}{   - 2}  \\ x > 4 \\  \\ comparing \\ 4 < x > 4

For sin2x+cosx=0, use a double-angle or half-angle formula to simplify the equation and then find all solutions of the equation
Archy [21]

Answer:

Step-by-step explanation:

Given is a trignometric equation in x, as

sin2x+cosx=0

TO make it in one trig ratio, we can replace sin2x as 2sinx cosx

WE get now

2sinxcosx+cosx=0\\

cosx(2sinx+1)=0\\cosx=0, sinx =-0.5\\

Principal solution is x=\frac{\pi}{2} , \frac{-\pi}{6}

x = ±π/2 + 2kπ, where k is any integer or

x=±pi/6 +k pi, where k is any integer.

General solution is
