So in the question we are given the points: (8,0) and (0,12)
In order to find the slope, we use the equation:
where subscripts 1 and 2 can apply to either of the points as long as they remain consistent. Let's use subscript 1 for the point (8,0) and subscript 2 for the point (0,12):
So now we know the slope of the equation is .
The slope-intercept form of a line follows the form:
where x and y are from a given point on the line, m is the slope of the line, and b is the y-intercept of the line.
So since we are told the y-intercept in the question, we can then plug in the numbers to the equation for the line:
So the answer to this would have to be worked out.
y = -7x + 1
You have two points, use those for the y and x.
1 = -7(0) + 1
1 = 1
The answer is yes.
Rewrite the logarithmic expresión log5 (100) using the change of base formula, which gets you:
log(100)/log(5)
Logarithm base 10 of 100 is 2.
2/log(5)
The result can be shown in both exact and decimal forms.
Exact Form:
2/log(5)
Decimal Form:
2.86135311...
Remember the angles add to 180, so 27 + 27 + x = 180
54 + x = 180
x = 126
The triangle is isosceles.
