Answer:
y = 4x +4
Step-by-step explanation:
-12x + 3y = 12
3y = 12 +12x ......bring x to opposite side and sign changes
y = 12 +12x / 3 .............bring 3 to oppsite side and it would divide
y = 4 + 4x ............result of diving and the answer of ours
y = 4x +4

Answer: y = 30x + 50
Step-by-step explanation:
let y be the distance traveled (in meters) after x minutes.
If we plot y on the vertical axis and x on the horizontal axis, a straight line would be formed. The slope of the straight line would be
Slope, m = (260 - 110)/(7 - 2)
m = 150/5 = 30
The equation of the straight line can be represented in the slope-intercept form, y = mx + c
Where
c = intercept
m = slope
To determine the intercept, we would substitute x = 7, y = 260 and m = 30 into y = mx + c. It becomes
260 = 30 × 7 + c = 210 + c
c = 260 - 210
c = 50
The linear model becomes
y = 30x + 50
Answer:
Step-by-step explanation:
Question 1
System of equations is,
y = -6x -------(1)
y = -4x - 2 ---------(2)
Substitute the value of y from equation (1) to equation (2)
-6x = -4x - 2
-6x + 4x = -2
-2x = -2
x = 1
From equation (1)
y = -6(1)
y = -6
Question (2)
System of equations is,
-y = x --------(1)
3x + 5y = 20 ---------(2)
Substitute the value of x from equation (1) to equation (2)
3(-y) + 5y = 20
-3y + 5y = 20
2y = 20
y = 10
From equation (1)
-y = x
x = -10
Question (3)
System of the equations is,
y = -2x - 7 --------(1)
9x - 10y = 12 ----------(2)
Substitute the value of y from equation (1) to equation (2)
9x - 10(-2x - 7) = 12
9x + 20x + 70 = 12
29x = 12 - 70
29x = -58
x = -2
From equation (1)
y = -2(-2) - 7
y = 4 - 7
y = -3
