The answer is c because your multiplying 7 by a number (k) subtracting by 3
Answer:
20$ is the answer of your question
C=6.28cm
because C=2pi•r
so in this case C=2•3.14•1
which is C=2•3.14
and that leads to C=6.28cm
hope this helped
Y-intercept: Let x = 0 and solve for y. Then y =2(0)^2 -(0) - 10 = -10. The y-intercept is (0,-1).
x-intercept: Let y = 0 and solve for x.
Then 0 = 2x^2 - x - 10. a=2, b= -1 and c = -10.
-(-1) plus or minus sqrt[ (-1)^2 - 4(2)(-10)
Then x = ------------------------------------------------------------
2(2)
1 plus or minus sqrt(81) 1 plus or minus 9
x = ----------------------------------- = ---------------------------

Calculate the 2 x-values. Let's call them "a" and "b." Then the x-intercepts (there are 2) are
(a, 0) and (b, 0)
X^3-x^2-17x+12....hope this helps
