When the difference between one and two numbers is two, the two numbers are -10 and -12.
Given that,
The difference between one and two numbers is two. Twelve more than six times the second is four times the first.
We have to find the number.
We know that,
The system of equation we get
x=y-2 ----->equation(1)
4x=12+6y ----->equation(2)
Substitute for x in the equation(2)
4(y-2)=12+6y
4y-8=12+6y
4y-6y=12+8
-2y=20
y=-10
Substitute y=-10 in equation(1)
x=-10-2
x=-12
Therefore, The two numbers area -10 and -12 when the difference between one and two numbers is two.

Slope-intercept form: y = mx + b
(m is the slope, b is the y-intercept or the y value when x = 0 --> (0, y) or the point where the line crosses through the y-axis)
To find the slope(m), use the slope formula:
And plug in the two points on the line
(-4, -4) = (x₁, y₁)
(4, -2) = (x₂, y₂)
(two negative signs cancel each other out and become positive)
Simplify the fraction
Now that you know the slope, substitute/plug it into the equation
y = mx + b
To find b, plug in either of the points into the equation, it doesn't matter which, then isolate/get the variable "b" by itself. I will use (4, -2)
-2 = 1 + b Subtract 1 on both sides to get "b" by itself
-3 = b
Your answer is A
Answer:
Step-by-step explanation:
12 * 4 = 48.
4 * 4 / 2 = 8
48 + 8 = 56 so the area is 56.
