Which equation does the graph of the systems of equations solve? two linear functions intersecting at 3, 2

−one thirdx + 1 = 2x − 4
one thirdx + 1 = −2x − 4
one thirdx + 1 = 2x − 4
−one thirdx − 1 = −2x − 4

1/8 3/16 3/4

step-by-step explanation:

you put them as all the same denominator and multiply

= 5

step-by-step explanation:

to find the 15th term substitute n = 15 into the nth term formula

= (- 3 × 15 ) + 50 = - 45 + 50 = 5

x² + 11x + 18 < 0  

[-11 ± sqrt(121 - 72)]/2 = (-11 ± 7)/2  

solution: (-9, -2)

step-by-step explanation:

answer: cos [   arcsin (3/5) - arccos (1/2) ] =

step-by-step explanation: × = 3/5 = 0.6--> x = 36.87 and x = 180 - 36.87 = 143.13 deg

cos y = 1/2 --> y = +- 60 deg a. cos (x - y) = cos (143.13 - 60) = cos 83,13  

=

0.12

b. cos (36.87 - 60) = cos (-23.23) = 0.92
