Do these 5 problems for your project and SHOW ALL your work. You can either factor or do the quadratic formula. 1. 3x^2 + 7x – 6 = 0 2. -x^2 – 2x + 8 = 0 3. -3x^2 – 2x – 5 = 0 4. x^2 – 1 = 0 5. x^2 + 4x – 7 = 0 (Last one you have to use quadratic formula) On each question tell what way you solved it and why.

80 the answer is 80

step-by-step explanation:

his first public project he is asked to create a small scale drawing. the garden is a right triangle with base 25m and height 30m. are you trying to solve for the last side/hypotenuse? the irrational form of the answer would be 5\sqrt{61}

55.44 inches

step-by-step explanation:

part a. assuming a perfectly linear relationship, we can find the slope from the first two data points.

slope = m = (change in rainfall)/(change in years)

= (61.80 -62.33)/(2005 -2004) = -0.53/1 = -0.53

then the point-slope form of the equation of the line can be written as

y = m(x -h) +k . . . . . m = -0.53, (h, k) = (0, 62.33)

y = -0.53x +62.33 . . . x = years after 2004

part b. in 2017, x = 2017 -2004 = 13. then the predicted rainfall is

y = -0.53·13 +62.33 = 55.44 . . inches

the predicted rainfall in 2017 is 55.44 in.
