The table represents a linear function. What is the slope of the function?

otez555 [7]

Answer:

-6

Step-by-step explanation:

The slope of a line is given with the formula

$m=\frac{y_2-y_1}{x_2-x_1}$

Using the first two points, (-2, 8) and (-1, 2), we have

m = (2-8)/(-1--2) = -6/(-1+2) = -6/1 = -6

Which graph represents this equation? Equation: y = 2/3x^2 - 6x

vovangra [49]

Answer:

I'm afraid that none of them are, as the x-intercepts of the equation are 0 and 9 respectively

however, D. is the closest to it, and it would be the correct graph if there were parentheses around $x^{2}-6x$

What is the quadratic formula of 4x2+3x+5=0

maxonik [38]

4x² + 3x + 5 = 0
x = -3 +/- √(3² - 4(4)(5))
 2(4)
x = -3 +/- √(9 - 80)
 8
x = -3 +/- √(-71)
 8
x = -3 +/- √(71 × (-1))
 8
x = -3 +/- √(71) × √(-1)
 8
x = -3 +/- 8.43i
 8
x = -0.375 +/- 1.05375i
x = -0.375 + 1.05375i x = -0.375 - 1.05375i
