Answer:
C. 129
Step-by-step explanation:
In the parallelogram, opposite angles are equal
So
<KJO = <KLM
but
<KLM = <KLO + <MLO = 68 + 61 = 129
so
<KJO = <KLM = 129
Answer
C. 129
Answer:
-0.69444 or about -0.69 or as a fraction it would be -25/36
Step-by-step explanation:
You can change 2 11/12 to and improper fraction, 35/12. You can also change -4 1/5 to an improper fraction, -21/5. Then you need to flip -21/5 to -5/21. You can work it out to get an improper fraction, to then follow and get -25/36 or -0.69.
Answer:
y ≤ 2x + 4 and x + y ≥ -6
Step-by-step explanation:
Graphing a system of inequalities is similar to graphing linear functions. It is best to have equations in the form of y = mx + b where m = slope and b = y-intercept. Looking at the graph, you can see that there is one line going uphill (positive slope) and one going downhill (negative slope). There are two y-intercepts, one from each line at (0,4) and (0, -6) So, only the top two equations have a y-intercept equal to 4 and -6. Then, you can find the slope of each line by choosing two points on the same line and using rise/run to find the change in 'y' over the change in 'x'.
Line #1 (uphill): (-2, 0) and (0, 4) = 4-0/0- -2 = 4/2 = 2
The only answer with a positve 2 slope and y-intercepts of 4 and -6 is the second one, so that is your answer.
