Sep 10, 2016 · 5 − 7x = −9 −7x = − 9 − 5 −7x = − 14 x = −14 −7x=2 >5-7x= -9 -7x= -9-5 -7x= -14 x= (-14)/ (-7)

Mar 15, 2016 · Answer: x=-7/2+-sqrt (85)/2 or x approx -8.11 or 1.11 To solve by completing the square, first add 9 to both sides x^2+7x=9 Then you have to manipulate the number in front of x, in this case 7.

Jan 13, 2017 · The slope is color (red) (-7) We can obtain the slope directly from this equation which is already in slope-intercept form. The slope-intercept form of a linear equation is: y = color (red) (m)x + color (blue) (b) Where color (red) (m) is the slope and color (blue) (b …

Sep 10, 2015 · So the answered is x = 2 and y = -3 In order to solve x + 3y = -7 and -x + 2y = -8, you must use the elimination method for solving linear equations. In this case, you will have to find y and x.

Sep 24, 2015 · 3x −4 = 7x + 9 3x −7x = 9 + 4 −4x = 13 x = − 13 4

Jul 13, 2018 · the equation of a line in slope-intercept form is. ∙ xy = mx + b where m is the slope and b the y-intercept y = − 7x −9 is in this form with slope = − 7 and y-intercept = −9

Sep 17, 2016 · We have: 3x − 7 = x −9 Let's collect the terms containing x on the left-hand side of the equation: ⇒ 3x − x = − 9 + 7 ⇒ 2x = − 2 Let's divide both sides by 2: ⇒ x = − 1

Mar 31, 2017 · Factor the trinomial into two binomials ( -2x + 9) * ( x + 1 ) The 7x shows that the positive factors must be greater than the negative factors. -2 can be factored into -1 xx 2, or -2 xx 1 +9 can be factored into 3 xx 3 or 9 xx 1 The combination that works is + 1 xx 9 and …

Jul 2, 2016 · How do you write f (x) = x2 − 7x + 9 in vertex form?(x-7/2)^2-13/4 (x^2-7x+49/4)+9-49/4 (x-7/2)^2-13/4

Jun 15, 2017 · See a solution process below: We can write this word problem as: (2x^2 - 11) - (7x - 9) First, remove all of the terms from parenthesis. Be careful to handle the signs of each individual term correctly: 2x^2 - 11 - 7x + 9 Next, group like terms: 2x^2 - 7x - 11 + 9 Now, combine like terms: 2x^2 - 7x + (-11 + 9) 2x^2 - 7x + (-2) 2x^2 - 7x - 2
