Step-by-step explanation:
the solution is in the picture
Since you have not given any choices to choose from there are a multitude of lines that would qualify as parallel to this line. To find a parallel line, any line that has the same slope as this line that is not the exact same line will be parallel. To find the slope, use the formula y2-y1/x2-x1.
4-7/-3-1
that simplifies to
-3/-4
then simplifying to
3/4
so any line that has a slope of 3/4 that is not the exact same line will be parallel to this line.
The quadratic formula is =(-b+-sqrt(b^2-4ac))/2a
as you notice the term under the square root is b^2-4ac if it is postive then the equation clearly will have two real soultions if it is negative then the equation will have two imaginary soultion if it is zero then the the equation will have one soultion
so let us calculate b^2-4ac for our given equation
x^2=4x-5 so let us write it in general form which is ax^2+bx+c=0
subtracting 4x from both sides
x^2-4x=-5
adding 5 to both sides
x^2-4x+5=0
a=1,b=-4,c=5
b^2-4ac=(-4)^2-4(1)(5)=16-20=-4
which means the equation has two imaginary soultions
7^2+5^2= 74 now you have to square root 74 which is 8.60233 or 8.6
Answer:
To determine the x-intercept, we set y equal to zero and solve for x. Similarly, to determine the y-intercept, we set x equal to zero and solve for y. ...
To find the x-intercept, set y = 0 \displaystyle y=0 y=0.
To find the y-intercept, set x = 0 \displaystyle x=0 x=0.
