What is the value of x if y equals x-2 and 7y-4x equals 10?
If: y = x -2 and 7y -4x = 10 Then: x = 8 and y = 6
What is the slope of 8x - 7y equals 56?
The simplest way is to rewrite the equation in the standard for: y = mx + c. Then the slope is m. 8x - 7y = 56 7y = 8x - 56 y = 8/7 * x - 8 So the slope is 8/7
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.
What is the value of y if 5y plus 8 equals 7y?
5y+8=7y 2y=8 y=4
Solve the system of equations Enter your answer as an ordered pair 4x plus 7y equals 60 negative 4x plus 7y equals negative 4?
4X + 7Y = 60 -4X + 7Y = - 4 -----------------------+ 14Y = 56 Y = 4 --------- insert back into one of these equations to find X 4X + 7(4) = 60 4X + 28 = 60 4X = 32 X = 8 ------------check 4(8) + 7(4) = 60 32 + 28 = 60 60 = 60 ----------------checks, now second equation -4(8) + 7(4) = -4 -32 + 28 = -4 -4 = -4 --------------checks solution set. X = 8 Y = 4 (8,4)
What is 16 plus 7y - 8?
16+7y-8 = 7y+16-8 = 7y+8
What is the equivlent expression of 7y x 7y x 7y?
343y3
What is the value of x if y equals x-2 and 7y-4x equals 10?
If: y = x -2 and 7y -4x = 10 Then: x = 8 and y = 6
What is the y-intercept of the graph of the equation 3x-7y equals 8?
Put in this form. Y = mX + c3X - 7Y = 8- 7Y = - 3X + 8Y = (3/7)X - 8/7===========Y intercept = - 8/7-----------------------
What are the x and y intercepts for the equation 8x-7y equals 168?
Put in function form. 8X - 7Y = 168 - 7Y = - 8X + 168 Y = 8/7X - 24 0 out Y 8/7X - 24 = 0 8/7X = 24 X = 21 ---------- 0 out X Y = - 24 ----------- (21,-24) X and Y intercepts.
Y= -1/2x + 7Y= x-8?
I think it is 16
What is -7y plus x?
x = 7y x/7 = y
Use elimination to solve the system x plus 7y equals 16 and 3x - 7y equals 4?
x+7y=16 ---------------------------1 3x- 7y=4 ---------------------------2 ------------------------------------------------------------------------------------------------------------------ 1+2 x+7y=16 3x-7y=4 4x=20 x=5 substitute x = 5 in x+7y=16 (5)+7y=16 7y=11 y=11/7
Factor -8x2 plus 40xy plus 112y2?
-8(x - 7y)(x + 2y)
Is 5y 9x 12 the answer to 12y 4 x-7y 8 8x?
No.
What is the slope of 8x - 7y equals 56?
The simplest way is to rewrite the equation in the standard for: y = mx + c. Then the slope is m. 8x - 7y = 56 7y = 8x - 56 y = 8/7 * x - 8 So the slope is 8/7
What is the answer to 16 plus 7y - 8 if yuh simplify?
It is: 8+7y
