Answer:
(- 1, - 1 )
Step-by-step explanation:
Given the 2 equations
y = 4x + 3 → (1)
x + y = - 2 → (2)
Substitute y = 4x + 3 into (2)
x + 4x + 3 = - 2, that is
5x + 3 = - 2 ( subtract 3 from both sides )
5x = - 5 ( divide both sides by 5 )
x = - 1
Substitute x = - 1 into (1)
y = 4(- 1) + 3 = - 4 + 3 = - 1
Thus x- value is - 1 and y- value is - 1
The table gives you x and y coordinates. The graph has an x and y axis. Your x coordinates are paired with your y coordinates. Remember to always start at the origin, when plotting your points. For example, if the table gave you 2 for x and 3 for y. You would go 2 units across and 3 units up. Then, plot that point. Continue plotting the points and then if it's a linear graph, make a line with a ruler going through the points.
Answer:
{x +4} {x+3} =0
Step-by-step explanation:
The equation is given as :
x² + 7x + 12 =0
Find multiples of 12 that can add to give +12 ------3 * 4
The equation can then be written as;
x² + 3x + 4x + 12 = 0 ------factorize
x{ x + 3 } + 4 { x +3 } = 0
{x+4 } {x + 3} = 0
Answer : {x +4} {x+3} =0
Answer:
1/5
Step-by-step explanation:
4/5 - 3/5 equals 1/5
Ax=15+bx
ax-bx=15
x(a-b)=15
x=15/(a-b)
