What is the slope-intercept form equation of the line that passes through 8 8 and 1 2?
Points: (8, 8) and (1, 2) Slope: (8-2)/(8-1) = 6/7 Equation: y-8 = 6/7(x-8) => 7y-56 = 6x-48 => 7y = 6x-48+56 Slope intercept form: 7y = 6x+8
What is the equivlent expression of 7y x 7y x 7y?
343y3
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
Solve the system 6x-7y-6 18-3y-6 using the addition method by what constant should one of the equations be multiplied if the x terms are to drop outthe correct answer-3 613?
3y+18=7y-6
X 7y 39 3x - 2y 2?
x+7y=39
What is the slope of the line 6x-7y10?
if: 6x - 7y = 10 then -7y = 10 - 6x y = 6x/7 - 10/7 The slope is now the coefficient of x, which is 6/7.
6x+7y=20Y=2x?
the solution to the system of equations 6x + 7y = 20 and y = 2x is (x, y) = (1, 2)

(9,6)
What is x plus y plus 6x plus 7y?
7x + 8y
What is 2 parenthesis 3x - 7y parenthesis?
It is: 2(3x-7y) = 6x-14y
4x plus 15Y equals 6x equals 7y X weighs as much as how many ys?
.225

What are some math parentheses math questions?
You mean like these?: 9 * 2 - (-2 + 9) + 15 / (4.5 + 3) (6x + 7y) * 2 (y - 6x)=(6x*2y)-(6x*12x)+(2y*7y)-(12x*7y)=12xy-72x^2+14y^2-84xy=14y^2-72x^2-72xy

If 4x-5y equals 4 and 6x-7y equals 10 what is the value of x?
4x - 5y = 4 & 6x - 7y = 10 This is a pair of simultaneous equations. Re-write as 4x - 5y = 4 6x - 7y = 10 To find the value of 'x; we need to eliminate 'y' To do this multiply the top eq'n by '-7' and the bottom equation by '5' . This brings the coefficients of 'y' to the same value, but one is plus(+) and the other is negative(-). Hence -28x + 35y = -28 30x - 35y = 50 Add the two eq'ns, this will eliminate 'y' 2x = 22 x = 11
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
