The expression (7x \cdot 3y) can be simplified by multiplying the coefficients and the variables separately. This results in (21xy). Thus, the simplified form of (7x \cdot 3y) is (21xy).
Transfer the equation into the standard format y = mx + c, where 'm' is the slope 7x - 3y = 4 : 7x - 4 = 3y 3y = 7x - 4 y = 7/3x - 4/3 : The slope is 7/3.
7x+3y=-52 3(8x-y=-74) 7x+3y=-52 24x-3y=-222 7x=-52 + 24x=-222 31x=-274 x=8.8387
y=mx+b 7x+3y=21 3y=21-7x *****_ y=7-2.3x *****_ m= -2.3 negative
What is the slope-intercept form of 7x-3y equals 4
4xy+1=3y-7x 4xy-3y=-7x-1 y(4x-3)=-7x-1 y=(-7x-1)/(4x-3)
It's just a mathematical polynomial: 7x + 3y.
Transfer the equation into the standard format y = mx + c, where 'm' is the slope 7x - 3y = 4 : 7x - 4 = 3y 3y = 7x - 4 y = 7/3x - 4/3 : The slope is 7/3.
7x+3y=-52 3(8x-y=-74) 7x+3y=-52 24x-3y=-222 7x=-52 + 24x=-222 31x=-274 x=8.8387
If the equation is 7x - 3y = 21 then (3, 0) and (0, -7).
y=mx+b 7x+3y=21 3y=21-7x *****_ y=7-2.3x *****_ m= -2.3 negative
What is the slope-intercept form of 7x-3y equals 4
4xy+1=3y-7x 4xy-3y=-7x-1 y(4x-3)=-7x-1 y=(-7x-1)/(4x-3)
9x-3y=63 7x-3y=45 -3y=63-9x -y=21-3x y=-21+3x 7x-3(-21+3x)=45 7x+63+9x=45 7x+9x=45-63 16x=-18 x=-1.125 y=-21+3(-1.125) y=-24.375 (-1.125,-24.375)
(14x-2y)+(7x-3y)+(-3x) = 14x-2y+7x-3y-3x =(14+7-3)x-(2+3)y =18x-5y
x+7x+3y-y =8x+2y =2(4x+y)
(7x-3y) + (2x+5y) = 9x+2y
7x-3y=21 Think of it this way. Block 3y or multiply 3(0)=0. Then you get: 7x=21 X=3 In vice versa, block 7x or multiply 7(0)=0 and look at: 3y=21 Y=7 So an ordered pair is (x,y) Thus, you get (3,7)
