Answer:
- C. f(x) = x³ + 10x² + 7x - 18
Step-by-step explanation:
If the function has a factor of x + 9, then the function will have a zero output at x = -9
<u>Lets verify:</u>
- A. f(-9) = (-9)³ - 8*(-9)² - 11*(-9) + 18 = -1260, No
- B. f(-9) = (-9)³ + 10*(-9)² + 7*(-9) - 27 = -9, No
- C. f(-9) = (-9)³ + 10*(-9)² + 7*(-9) - 18 = 0, Yes
- D. f(-9) = (-9)³ - 8*(-9)² + 11*(-9) + 27 = -1449, No
B 25% percent because 15/60 is 25
Answer:
9
Step-by-step explanation:
Because you know that 350 x 10 is 3500 but if you want it in the middle it will be 9
So Daniel is just useless info in this question so ignore that, Lara earns 5.25 an hour but has to get more than 500 dollars... So divide 500 by 5.25 to get how many hours she needs minimum, this gives you 95.24 hours when rounded to nearest hundredth meaning that Lara has to work that many hours to get 500 dollars with hours to be shown as h. So h>95.24 to let Lara make more than Josh
Answer:
y + 4 = -3(x - 2)
Step-by-step explanation:
Perpendicular lines have opposite reciprocal slopes. Since the slope of the given line is 1/3, a perpendicular line would have a slope of -3. We know that the line goes through the point (2 , -4), so we can use point-slope form to write an equation.
Point slope: 
y + 4 = -3(x - 2)
If necessary, this can be written in slope-intercept form as well. In this case, you'd solve for y.
