What does y equals 3x plus y and y equals x-9 equal?
y = 3x + y => x = 0then y = x - 9 => y = 0 - 9 = -9.
Evaluate x plus y for x 16 and y 14?
If you mean: x = 16 and y = 14 then x+y = 30
How do you Substitute x equals y plus 3 into x plus 2y equals 9?
x = y+3 x+2y = 9 => x = 9-2y y+3 = 9-2y 2y+y = 9-3 3y = 6 y = 2 and x = 5
X plus y equal to -1 and 4x minus 3y equal to 12 what is the answer?
x + y = -1 (a) 4x - 3y = 12 (b) 3(a)+(b) gives 3x + 3y + 4x - 3y = -3 + 12 or 7x = 9 or x = 9/7 then x + y = -1 gives y = -1 -x = -1 - 9/7 = -16/7 So, x = 9/7 and y = -16/7
5x plus y -1 y 6x plus 10?
11x+2y+9 is the final answer.
What is x squared plus 85xy plus 36y squared?
It is a quadratic expression in the variables x and y.
How does 3x plus 9y equals 36 using the same method as 12x plus 4y equals 18?
We have 3x+9y=36, or equivalently 12x+36y=144. We also have 12x+4y=18, so subtracting these we have 32y=126 or y=63/16. Substituting this into our original equation leaves 3x=36-9*63/16 or x = 12-3*63/16 = 3/16. So: x=3/16, y=63/16
What does evaluate 16y plus 9 for y equals 3 mean?
Replace the y with a 3. 16 x 3 + 9 = 57
How do you find the percentage of numbers with variables?
Calculate the percentage for the numbers and then put the variables back in the answer.For example,20% of 36y = (20% of 36)*y = 7.2*yor25% of 36/y = (25% of 36)/y = 9/y.
What is the center of the circle given by the equation (x - 3)2 plus (y - 9)2 16?
If you mean: (x-3)^2 +(y-9)^2 = 16 then the center of the circle is at (3, 9)
9 plus y plus y?
y is an unknown. For now, let's just call y an apple. 9+ apple +apple would be a 9 and 2 apples, right? So 9 plus y plus y is 9+ 2y. Without knowing the value of y, that is as far as you can go.
What is the answer to y2 plus 8y plus 7?
If you mean y2+8y+7=0 then it is a quadratic. y2+8y+7+9-9=0 y2+8y+16-9=0 (y+4)2=9 y+4=3 , y+4=-3 y=-1 , y=-7 So y can equal -1 or -7.
What does 8y over y plus 2 plus 16 over y plus 2 equal?
8y/y + 2 + 16/y + 2 = 8 + 2 + 16/y +2 = 12 + 16/y = 4(3 + 4/y) or 4/y*(3y + 4)
The equation of tangent to curve y x 2 at 4 16 is 8x plus y plus 16 0 8x-y-16 0 8x-y plus 16 0 8x plus y-16 0 B is right answer how?
There is not a way to give the answer to this equation. You will have to give me the value of the letters.
3x plus y equals 5 and 4x-7y equals -10?
3x+y=5(4x-7y)=-10 3x+y=20x-35y=-10 -3x -3x y=17x-35y=-10 -y -y 17x-36y=-10 sorry but that's as far as i could get :(
How do you plot x plus y equals 9 x-y equals 7?
16
If y equals a plus 12 times x plus 3 and y equals 4ax are parallel what is the value of a?
y = (a + 12)(x + 3) (line 1)y = 4ax (line 2)Since the equation of the second line is in a slope-intercept form, write the equation of the first line in the slope-intercept form, y = mx + b, where m is the slope of the line.y = (a + 12)(x + 3)y = a(x + 3) + 12(x + 3)y = ax + 3a + 12x + 36y = ax + 12x + 3a + 36y = (a + 12)x + 3a + 36, where the slope is a + 12y = 4ax, where slope is 4aSince the lines are parallel they must have the same slope. So that,a + 12 = 4a3a = 12a = 4Thus, when a = 4, the parallel lines have a slope of 16.
