Solve the quadratic equation numerically (using tables of x- and y-values). x2 + 2x + 1 = 0
a. x= -1
b. x=1 or x=-3
c. X=-3
d. x= 2 or x = -1
i’m timed please helpp

Solve by any method (graphing, substitution or linear combination)y = x - 82x + 3y = 1a) (2, -6)b) (5, -3)c) (4, -4)d) (0, -8)i figured it out. the answer is (5, -3)

25 ! the line of best fit is h = 5a + 86. predict the height at age 16.

Suppose that a households monthly water bill (in dollars) is a linear function of the amount of water the household uses (in hundreds of cubic feet, hcf). when graphed, the function gives a line with slope of 1.65. if the monthly cost for 13 hcf is $46.10 what is the monthly cost for 19 hcf?
