Answer: (x+2)*(x-4)*(x+21) = 0 has "many" solutions
Step-by-step explanation: (x+2) = 0 only has one solution.
(x+2)*(x-4) = 0 has two solutions, -2 and 4
(x+2)*(x-4)*(x+21) = 0 has three solutions, -2, 4, and -21, etc
If "many" means more than three, then add another (x+XX) term. A quadratic equation generally has two solutions.
Help!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Slope is calculated as the change in y over the change in x so you would need to do 5- (-5) which turns the negative sign to a positive making it 5+5=10 and the same thing with the 2s 2-(-2)=4 so the answer would be 10/4 or 5/2. Billy did the reciprocal.
Answer:
correct answer is 5/2
Step-by-step explanation:
the mistake was the student took the difference of the x-values and it in the numerator and the difference of the y-values should be the denominator
5-(-5) / 2-(-2) = 10/4 or 5/2
. Let g(x) = 3x2 + 4X – 36. What is g(2)?
Answer:
Step-by-step explanation:
The notation means that wherever you see an x on the right, you let it equal 2.
g(x) = 3x^2 + 4x - 36
x = 2
g(2) = 3*2^2 + 4*2 - 36
g(2) = 3*4 + 8 - 36
g(2) = 12 + 8 - 36
g(2) = 20 - 36
g(2) = - 16

Which equation represents the line that passes through the points (-3;7) and (9,-1)
Answer:
[tex]y = - \frac{2}{3} x + 5[/tex]
Step-by-step explanation:
[tex]y = mx + b[/tex]
finding the slope m of the line using the above points
[tex] m = \frac{y2 - y1}{x2 - x1} = \\ \frac{ - 1 - 7}{9 - - 3} = \frac{ - 8}{9 + 3} = - \frac{8}{12} = - \frac{2}{3} [/tex]
substitute the slope and one of the points into the y-intercept form to solve for b
[tex]y = mx + b \\ 7 = - \frac{2}{3} ( - 3) + b \\ 7 = \frac{6}{3} + b \\ 7 - 2 = b \\ b = 5[/tex]
therefore the answer to the question is
[tex]y = - \frac{2}{3} x + 5[/tex]
