2016年1月3日 · How do you solve the following system: # 7x − 5y = −11, 7x - y = 10 #? Algebra Systems of Equations and Inequalities Systems Using Substitution 1 Answer

2015年8月28日 · color(red)((–7x–11)(19x–14) = -133x^2 - 111x + 154) "FOIL" stands for "F"irst, "O"uter, "I"nner, "L"ast. Your expression is (–7x–11)(19x–14). So you take each product in turn and then add them up. We multiply the "F"irst term in both parentheses together: -7x×19x = -133x^2 Then the "O"uter terms -7x×(-14) = 98x Then the "I"nner terms -11×19x= -209x And finally the "L"ast terms ...

2015年7月24日 · One way of doing this is to express #(x^2+7x+11)/(x+5)# into partial fractions.. Like this : #f(x)=(x^2+7x+11)/(x+5) color(red)= (x^2+7x +10-10+11)/(x+5) color(red ...

2017年2月11日 · First, add #color(red)(11)# and subtract #color(blue)(7x)# from each side of the inequality to isolate the #x# term while keeping the inequality balanced:

2016年11月4日 · The slope = -7 y= -7x +11 If you have the equation of a straight line given in this form, you immediately know both the slope and the y-intercept. y= mx +c is known as the 'slope-intercept form' m = the slope and c = the y-intercept, (0,c) The slope = -7

2018年3月30日 · x = 3 and y =-10 Rearrange the first equation to get: y = 11 - 7x Substitute this into the second equation: 3x + 2(11 - 7x) = -11 Expand the bracket: 3x + 22 - 14x = -11 22 - 11x = -11 33 = 11x x =3 Now substitute x = 3 into any of the three equations to find y: y = 11 - …

2017年7月22日 · See a solution process below: First, write this problem in algebraic form as: (2x^2 - 11) - (7x - 9) Next, 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 ...

2017年8月31日 · 12x + 9 7x + 11 - (- 5x + 2) First is to eliminate the brackets! 7x + 11 + 5x - 2 What is done above is the general terms with the symbols..

2017年6月15日 · 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

2016年6月22日 · Write as a long division problem: #color(white)("XXXX")underline(color(white)("XXXXXXXXXX")# #7x+3 ) 4x^2-17x-11#
