What is 7x plus 3y?
It's just a mathematical polynomial: 7x + 3y.
What is 5x - 3y -7x plus 2y plus 3x?
5x - 3y -7x + 2y +3x = (5-7+3)x + (-3+2)y = x - y
How do you solve 5X plus y equals -12 7X -3y equals -30 by elimination method?
(1) 5x+y=-12 (2) 7x-3y=-30 From (1) one gets y = -12-5x Put into (2) 7x-3y = 7x -3 (-12-5x) = 7x + 36 +15 x = 22x +36=-30 22x = -30-36 = -66 so x = -3 and y=-12-5x = -12-5x-3= 3 The solution is (-3,3)
7x equals 5 plus 5x?
7x = 5+5x 7x-5x = 5 2x = 5 x = 2.5
What is 5x plus 5 plus 7x equals 47 plus 5x?
x=6
How do you solve 7x plus 3y equals 30 -2x plus 3y equals 3 in an order pair?
(3,3)
If x equals 2 and y equals 9 then 7x plus 3y equals?
7x+3y where x=2 and y=9 can be written as (7*2)+(3*9) which can be simplified to (14)+(27), from there it's basic addition.
Find the answers in 4x plus 3y equals 12 7x plus 3y equals 21?
x = 3 and y = 0
7x plus 3y equals fourteen and 5x plus 9y equals ten What is the value of x and y?
7x + 3y = 14 5x + 9y = 10 __________ (subtract bottom from top) 2x -6y = 4, therefore 2x = 4 + 6y, therefore x = 2 + 3y Insert x = 2 + 3y into the original equation and calculate 7(2 + 3y) +3y = 14 14 + 21y +3y = 14 24y = 0 y = 0 If y= 0, then x = 2 FINAL ANSWER!
What is the ordered pair for 7x-3y equals -52 and 8x plus 74 equals y?
7x+3y=-52 3(8x-y=-74) 7x+3y=-52 24x-3y=-222 7x=-52 + 24x=-222 31x=-274 x=8.8387
How do you put 7x plus 3y equals 42 in slope-intercept form?
7x + 3y = 42 can be converted to slope intercept form using the formula y = mx + b. First, get 3y on to the outside. -3y = 7x - 42 Divide everything by -3. You are left with y = 7/3x + 14
What is 7x plus 3y equals 21 a negative or positive slope?
y=mx+b 7x+3y=21 3y=21-7x *****_ y=7-2.3x *****_ m= -2.3 negative
7x plus 3y equals 56 and 6x plus 6y equals 72 What is the ordered pair?
(5,7)
What does 14x-2y plus 7x-3y plus -3x equal to?
(14x-2y)+(7x-3y)+(-3x) = 14x-2y+7x-3y-3x =(14+7-3)x-(2+3)y =18x-5y
Rewrite the equation 7x plus 2y equals 0 in slope-intercept form?
7x = -3y + 12
How do you rewrite the equation so that y is a function of x 3x plus 3y equals 14 minus 4x?
3x + 3y = 14 - 4xSubtract 3x from each side:3y = 14 - 7xDivide each side by 3:y = (14 - 7x) / 3
What is 7x plus 3y?
It's just a mathematical polynomial: 7x + 3y.
