Answer:
x=0.25 or -1/4
Step-by-step explanation:
120x + 21 = -9
120x = -30 (-21 from both sides of equation)
x = -0.25 or -1/4 (divide 120 from both sides of equation)
Half the x-coefficient is -3, so the equation needs to be rearranged into a form that looks like
x² -6x +(-3)² + [something]
You can get there by adding and subtracting 9 from the original equation.
y = x² -6x +9 +7 -9 . . . . . 9 added and subtracted
y = (x² -6x +9) -2
The quantity in parentheses is a perfect square, so we can write the equation in the desired form as ...
y = (x -3)² -2
Answer:
Points she needs to earn on the next game = 14
Step-by-step explanation:
Martiza scores for six games were 11, 12,10,8,14, and 15.
(11+12+10+8+14+15+x)/7=12
(70+x)/7 = 12
Multiply both sides by 7
(70+x)/7 *7 = 12*7
70+x = 84
Combine the constants:
x=84-70
x = 14
Points she needs to earn on the next game = 14....
