PLISS ANSWER :C DONT ANSWER IF YDK THAnKSSS<br> *also pls look at both images :)*
vovikov84 [41]

Answer:

First image: (6, -1)

2nd image: y = 63

Explanation:

1)

2x + y = 11

1/2x - 5y = 8

y = -2x + 11

1/2x - 5(-2x + 11) = 8

1/2x + 10x - 55 = 8

10.5x - 55 = 8

10.5x = 63

x = 6

2x + y = 11

2(6) + y = 11

12 + y = 11

y = -1

(x , y) = (6, -1)

2)

1/4(8y - 4.8) = 2 (0.9y + 5.4) + 3/5

2y - 1.2 = 1.8y + 10.8 + 0.6

0.2y - 1.2 = 11.4

0.2y = 12.6

y = 63

Find the least positive angle measurement that is coterminal with -230°.
Alex Ar [27]
The answer is Letter C - 130<span>°
</span>
Coterminal Angles are angles that share a common terminal or end position. In finding the coterminal angle, you can add or deduct 360°. In this case, you are asked to get its positive coterminal angle. You will simply add 360° to -230°.

Solution: 360° + -230° = 130°

For problems 1, 2, and 3, use the function g(x) = sin(6x) .
Fantom [35]

Step-by-step explanation:

1. Amplitude = 1.  g(x) = 1 sin(6x).  The coefficient 1 is the amplitude.  The range of the function is -1 \le g(x) \le 1  or, in interval notation, [-1, 1]

2. The period is  \frac{2\pi}{6}=\frac{\pi}{3}.

x-intercepts (at the beginning, middle, and end of the period) 0,\,\frac{\pi}{6},\,\frac{\pi}{3}

Maximum (1/4 of way through period)  \left(\frac{\pi}{12},\,1 \right)

Minimum (3/4 of way through period)  \left( \frac{\pi}{4}, \, -1 \right)

4. A scientist changes the temperature of a solution at a rate of -7°C per minute. How many minutes will it take for
igomit [66]

Answer:

7 minutes

Step-by-step explanation:

The scientist changes the temperature for the solution at a rate of -7°C per minute. We need to find out how long it'll take for the solution's temperature to change from  0°C to -49°C. So, we divide -7 by -49 to find out how long it will take:

-49 / -7 = 7

It will take 7 minutes for the temperature to reach -49°C.
