3. Use completing square method to evaluate 6x2 + 11x +3 = 0

x=-1/3 or x = -3/2

Step-by-step explanation:

6x²+11x+3=0

divide through by 6

x² +11x/6 + 3/6 =0

collect like terms that is those with x should be left on one side nd the one without x should be on the other side

x² +11x/6 = -1/2

add the square of the half of the co efficient of B i.e 11x/6 to both sides

(x+11/12)² = 121/144 -1/2

(x+11/12)² = 121-72/144

square root of both sides

x+11/12 =+or - √49/144

x= -11/12 ± 7/12

x= -1/3 or x= -3/2

i believe it is c.y = 9x

rise over run. 9 units up over 1 unit right or 9/1

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
