X² - 6x + 7 = 0
x² - 6x = -7
x² - 6x + 9 = -7 + 9
(x-3)² = 2
Answer: 2/5 = 0.4 = 40%
Step-by-step explanation:
Each sector has an equal area, so each sector has an equal chance of being landed on. There are two shaded sectors and 5 total, so there is a 2 out of 5 chance that the spinner will land on a shaded one.
Answer:
y = (3/4)x - 9
Step-by-step explanation:
The slope-intercept form of the equation of a straight line is y = mx + b.
Here we know x, y and m, but must find b.
Substituting 8 for x, -3 for y and 3/4 for m in the equation above results in:
-3 = (3/4)(8) + b, or (after multiplying all three terms by 4 to clear fractions):
-3 = 6 + b
Then b = -9, and the desired equation is y = (3/4)x - 9
-2, 0, 2, and 4 are the x values. To find y, we must substitute x for each of these values in y = -3/2x + 2.
-3/2 times -2 = 3. 3 + 2 = 5. The y value that goes with -2 in the table is 5.
-3/2 times 0 = 0. 0 + 2 = 2. The y value that goes with 0 is 2.
-3/2 times 2 = -3. -3 + 2 = -1. The y value that goes with 2 is -1.
-3/2 times 4 = -6. -6 + 2 = -4. The y value that goes with 4 is -4.
So, the table/coordinates are:
(-2, 5)
(0, 2)
(2, -1)
(4, -4)
I hope this makes the process clear.
