1 Find the slope of a line perpendicular to 4x 5y 7?
the slope is -5/4
Is 5 a solution to 4x plus 7?
4x + 7 is an expression, not an equation. Only an equation (or an inequality) can have solutions, an expression cannot have a solution.
What is the sum or difference of 4x-5y 3 2x 7y-7?
There is x left. [One x]
Given the equation 7x - 5y equals 35 rewrite the given equation in slope intercept format?
slope intercept form is y = mx + b where m=slope and b=y-interceptfirst solve the equation for y7x-5y=357x=5y+355y=7x-35y=7x/5-35/5y=(7/5)x-7so the slope is 7/5 and the y-intercept is -7
What is the difference between an algebraic expression and an algebraic equation?
An algebraic expression doesn't have an equal sign (e.g. 4x+7) whereas an algebraic equation does (e.g. 4x+7=19). 4x=19-7 4x=12 x=12/4 x=3
What is the slope of every line perpendicular to the graph of this equation 4x plus 5y equals 7?
4x+5y = 7 5y = -4x+7 y = -4/5x+7/5 in slope intercept form So the slope of the perpendicular line is plus 5/4
What is negative X plus 5Y subtract 4X plus 7 simplified?
- X + 5Y - 4X + 7 gather terms - X - 4X ( same as - X + (- 4X ) 5Y 7 = - 5X + 5Y + 7 ----------------
What is 5y equals 4x-35 and slove for y?
5y = 4x - 35 Divide each side of the equation by 5 : y = 4/5 x - 7
What is the y intercept for -5y-35 equals -4x?
-5y-35 = -4x -5y = -4x+35 y = 4/5x-7 The y intercept is -7
How do you elimination 2x-5y equals 11 4x plus 10 equals 18?
Start with the second part of your equation 4x + 10 = 18 4x = 8 Subtract 10 from both sides x = 2 Divide by 4 on both sides Now substitute 2 for x on the first part of your equation 2 (2) - 5y = 11 4 - 5y = 11 Simplify -5y = 7 Subtract 4 from both sides y = -7/5 or -1.4 Divide by -5 on both sides
4x-5y equals 20 equals x-3y equals 10?
4x-5y=20 x-3y=10 becomes x=3y-10 plug that into the first equation: 4(3y-10)-5y=20 12y-40-5y=20 7y=60 y=60/7 If x=3y-10, then x=3(60/7)-10 x=180/7 - 70/7 x=110/7
4x - 2y equals -2 4x plus 5y equals 33?
First arrange this simultaneous equation in the form of: 4x+5y = 33 4x-2y = -2 Subtract the bottom equation from the top equation remembering that a - - is equal to a +: 7y = 35 Divide both sides by 7 to find the value of y: y = 5 Substitute the value of y into the original equations to find the value of x: So: x = 2 and y = 5
How do you rewrite this equation so that y is a function of x -- 3x plus 5y equals 7?
Because of the limitations of the question software, it was not possible to determine what the original equation was supposed to be, so we assumed it is 3x + 5y = 7. It could have just as easily been 3x - 5y = 7, or even 3x/5y = 7.So, let's solve them all for x.3x + 5y = 73x = 7 - 5yx = (7 - 5y)/3How about 3x - 5y = 7?3x - 5y = 73x = 7 + 5yx = (7 + 5y)/3And 3x/5y = 7?3x/5y = 73x = 35yx = 35y/3 Solving for y The above equations wrote the equation so that x is a function of y, not the other way around. Here's how to rewrite the equation so that y is a function of x: 3x + 5y = 7 5y = -3x + 7 y = (-3x + 7)/5
What does 2x plus 5y equal 4 and x plus 5y equal 7?
Is this a system of equations? 2X + 5Y = 4 X + 5Y = 7 solve for X using bottom equation X = 5Y - 7 insert into top equation 2(5Y - 7) + 5Y = 4 distribute 10Y - 14 + 5Y = 4 solve for Y 15Y = 18 Y = 18/15 = 6/5 use bottom equation to find X X +5(6/5) = 7 X = 1 check with bottom equation 1 + 5(6/5) = 7 7 = 7 not true for top equation ( sorry, I forgot what happens then-resubmit question )
How do you Rewrite this equation 3x plus 5y equals 7?
3X + 5Y = 75Y = - 3X + 7Y = (-3/5)X + 7/5==================equation of the line
Which is equivalent to 3x divide by 7 plus 5y divided by 14x?
3x/7 + 5y/14x = 3x*2x/(7*2x) + 5y/14x = (6x2 + 5y)/14x
Find the slope of a line perpendicular to 4x plus 5y equals 7?
