Find the values of m and b that will create a system of equations with no solution. Check all that apply.

1 answer:

7 0

Y = mx + b ; where m is the slope and b is the y-intercept.

A) y = -2x + 3/2 ; The slope is -2

For the system of equation to have no solution, they must form parallel lines. Parallel lines have the same slope. They don't intersect, thus, there is no solution.

C.) m = –2 and b = -1/3
F.) m = –2 and b = -2/3

If cos -105º = -0.26 and csc -105º = -1.03, then cos 105º = and csc 105º = .

andreyandreev [35.5K]

Answer:

cos (105°) = - 2.6

csc (105°) = 1.03

Step-by-step explanation:

Given that cos (-105°) = - 0.26 {The negative sign is due to the angle - 105° lies in the third quadrant where cos value is negative}

Again, given that csc (- 105°) = - 1.03 {{The negative sign is due to the angle - 105° lies in the third quadrant where csc value is negative}

Now, cos (105°) = - 2.6, because 105° lies in the second quadrant and here cos value is negative.

And csc (105°) = 1.03, because 105° lies in the second quadrant and here csc value is positive. (Answer)

Cooper earned $228.00 at his job when he worked for 10 hours. How much money did he earn each hour?

mote1985 [20]

Answer:

Cooper made $22.80 per hour.

Step-by-step explanation:

Since Cooper made a total of $228.00 within 10 hours, the money he made each hour is equivalent to the rate of change. That means that in order to get the amount of money made in one hour, you must first turn the ten hours into one using division. Since you divided ten into one using division, you divide the $228.00 by ten using division.

228 divided by 10 is 22.8, therefore Cooper is making $22.80 per hour.
