Answer:
The number is 86
Step-by-step explanation:
Let the number be , then the reverse is
The sum of the reversed number and the original number is 154,
We simplify this to get:
....eqn(1)
If the ones digit in it is 2 less than the tens digit, then
....eqn(2)
Putt equation (2) in (1)
Put x=8 in the second equation:
The original number is 86
The function rule in slope-intercept form is y = -4x -2
<h3>What is a function ?</h3>
A function is defined as the mathematical statement which defines relation between a dependent variable and an independent variable.
A function f(x) is graphed on the coordinate plane.
The equation for a straight line is given by
y = mx + c
Where m is the slope and c is the intercept on y axis
The intercept on y axis is -2
c = -2
At x = 0 , y =-2
At x = -1 , y =2
m =(2 -(-2))/(-1-0)
m = -4
Therefore ,the function rule in slope-intercept form is y = -4x -2 .

Answer:
14
Step-by-step explanation:
1) To find the distance between two points you'll need to use the distance formula:
d=
2) Figure out which points you'll want to set:
(x1,y1) = (-4,2) (x2,y2) = (10,2)
3) Substitute your values into the formula:
The answer is gonna be 415
