Step-by-step explanation:
Did you watch the video?
The y-coefficients have opposite signs and one is a multiple of the other. It is convenient to divide the second equation by 2 and add that to the first.
(5x -2y) +1/2(4x +4y) = (3) +1/2(8)
7x = 7 . . . . simplify
x = 1 . . . . . divide by 7
__
4(1) +4y = 8 . . . . substitute for x in the second equation
4y = 4 . . . . . . . . subtract 4
y = 1 . . . . . . . . . . divide by 4
The solution is (x, y) = (1, 1).
The answer is D) {x|x≥−3}
The x value’s lowest input in -3, and the function goes to the right, meaning it is greater than -3
Answer:
Step-by-step explanation:
The total angle of a circle is 360
If you divide that angle into six parts, you are basically multiplying by 1/6.
You multiply the total angle measure of the circle by 1/6 (or divide it by 6) to get the answer which is the 2nd blank.
1/6 * __360_ = __60__
:)
The answer is D because the temperature between 7:00 am and 9:00 am is decreasing by 5
