Answer: There is no inverse of f(x)=-457-1
Step-by-step explanation:
The slope intercept form of a straight line is
y = mx + c where m = slope and c = y-intercept
so here we have c = 3.
and
y = mx + 3
WE can find the slope m as follows
m = (5-3) / ( 4 - 0) = 2/4 = 1/2
So our equation is
y = 1/2 x + 3
or we could write it as
2y = x + 6
or
-x + 2y = 6 (standard form)
The equation -3=x^2+4x+1 can be rearranged into x^2+4x+4=0, you should be able recognise that this is an equation of the form ax^2+bx+c (where a, b, and c are constants). The question tells you that the discriminant of an equation of form ax^2+bx+c is equal to b^2-4ac, therefore after rearranging the equation you simply substitute the numbers in:
a=1 b=4 c=4
b^2-4ac=(4)^2-4x(1)x(4)=16-16=0
Therefore the discriminant value is 0.
To determine the amount of real solutions an equation has you look at the discriminant, if the discriminant is less than 0 there are no real solutions, if the discriminant is equal to 0 there is one solution, and if the discriminant is more than 0 there are 2 solutions. therefore as our discriminant is equal to - there is 1 real solution.
Given two points (x₁,y₁) and (x₂,y₂) the slope of the line passes through these points will be:
m=(y₂-y₁)/(x₂-x₁)
Data:
The points are (-4,7) and (-2,17), then the slope will be:
m=(17-7)/(-2+4)=7/2
Answer: the slope of the line passes through these points would be 7/2
Answer:
39 ft squared
Step-by-step explanation:
If we divide the shape into shapes, we get a 3 by 2 rectangle and a 11 by 3 rectangle. 3*2=6 and 11*3 = 33. 33+6 = 39
