Answer:
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
Interval Notation: (-∞, 8)
The equation (in terms of x ) of the line through the points (-3,5) and (1,-7) is y = -4x - 3
The formula for calculating the equation of a line is expressed as;
y = mx + b where
- m is the slope
- b is the y-intercept
Given the coordinate points (-3,5) and (1,-7)
Get the slope
Get the y-intercept
Recall that y = mx+ b
-7 = -4(1) + b
-7 = -4 + b
b = -7 + 4
b = -3
Get the required equation:
y = -4x + (-3)
y = -4x - 3
Hence the equation (in terms of x ) of the line through the points (-3,5) and (1,-7) is y = -4x - 3

Answer:
So then the best option on this case is:
A. 14 and 15
Step-by-step explanation:
When we have a right triangle we can use the Pythegorean identity given by:
(1)
Where Hip represent the hypothenuse. Opp represent the opposite side and Adj the adjacent side.
On this case we have given the hypothenuse assumed because is the only possible reasonable value because
is a too much higher value
We have a ratio provided on this case, let's assume that the ratio is:
If we rpelace this condition into equation (1) we got:
And then we have this:
And then the opposite side is:
The perimeter is defined as the sum of all the sides, we can find the perimeter like this:
And replacing the values that we found we got:
So then the best option on this case is:
A. 14 and 15
