Does x plus y equals 13 if x if x is 6 and y is 7?
yes.
What type of lines are these x plus 2y equals 7 and 2x - y equals 7?
x + 2y = 7 2y = -x + 7 y = -(x-7)/2 => -x/2 + 7/2 2x - y = 7 -y = -2x + 7 y = 2x + 7 Since -1/2 is the negative reciporical of 2, the slopes of these equations are perpendicular. Therefore, these two lines are perpendicular.
Use the substitution method to solve the system of equations Enter your answer as an ordered pair y equals x - 7 x plus y equals 5?
y = x - 7 x + y = 5 Substituting for y in the second equation, x + (x - 7) = 5 or 2x = 12 so that x = 6 Then, from the first equation, y = 6 - 7 = -1 So, (x, y) = (6, -1)
X-y equals 5 2x plus y equals 7 answer?
x - y = 5 + 2x + y = 7 => 3x + 0 = 12 => 3x = 12 => 3x/3 = 12/3 => x=4 x-y=5 2x+y=7 =>4-y=5 =>2(4)+y=7 =>y=4-5 =>8+y=7 =>y=-1 =>y=-1 So, the answer would be x=4 and y=-1
What are the X-intercept of the graph of the following Equation y equals x2 plus 6x-7?
x-intercept happens when y=0 0=x2+6x-7 0=(x - 1)(x + 7) x-intercepts are x=1 and -7
How do you solve y equals 7 plus x?
y=7+x =x=7-x
What is y equals x plus 3 plus 4?
Y = x - 7
What is y when x plus 4y equals 7?
y=(7-x)/4
What is another solution for the equation x plus y equals 7?
Another solution for x+y = 7 is y = -x+7
Write x plus 7 equals y in standard form?
y = x + 7
Y2 plus x2 65 y plus x 7?
If you mean: y^2 + x^2 = 65 and y + x = 7 then the solutions are as follows:- When y = -1 then x = 8 When y = 8 then x = -1
What is the answer to x plus y equals -7?
There could be many answers. If X=(-14) then Y=7 If X=0 then Y= (-7) etc.
What is the y intercept for y equals -x plus 7?
The intercept is [ y = 7 ] .
What is the y intercept of x plus 7y equals 7?
x + 7y = 7 ⇒ 7y = -x + 7 ⇒ y = -x/7 + 1 ⇒ y intercept is 1.
If x equals 7 and y equals 2x plus 3 what is 5x plus y?
If: x = 7 Then: y = (2*7)+3 = 17 And: 5x+y = (5*7)+17 = 52
How do you factor x2-y2 plus 7x plus 7y?
(x - y + 7)(x + y)
What is 8 plus y plus 7 plus x?
The given expression is the same as 15+x+y simplified
