Answer:
y=3
Step-by-step explanation:
it says that y is the inverse of x so if x=3 and y=8, so if x=8 than y must equal 3
 
        
                    
             
        
        
        
The standard form of a hyperbola is <span><span><span>x2/</span><span>a2 </span></span>− y<span><span>2/ </span><span>b2 = 1
the tangent line is the first derivative of the function</span></span></span><span>y′ = <span>b^2x/ a^2 y
hence the slope is </span></span><span>m = <span>b^2 x0 / <span>a^2 <span>x1
</span></span></span></span>Therefore the equation of the tangent line isy−x1 = b^2 x0 / a^2 x1* (x−x0)
 
        
             
        
        
        
Answer:
y = -2x + 3 
Step-by-step explanation:
y2 - y1/ x2 - x1
7 - (-5) / -2 - 4
-2 
The slope is -2. 
To find the y-intercept, you need to plug the coordinates into the equation.
y = -2x + b
7 = -2(-2) + b
7 = 4 + b
3 = b
y = -2x + 3 
 
        
             
        
        
        
Answer:
no. 
Step-by-step explanation:
since 2 of the sides are much longer than the shorter sides, diagonals of a rectangle will not intersect at a right angle (perpendicular) whereas a square, with all sides equal, would. This is because the distance from the center to each of the corners is the same for each corner. 
 
        
             
        
        
        
Answer:
Option 2, 3, 4
Step-by-step explanation:
It cannot be the 1st option because a linear function doesn't have an  and adding an x to an x will not make it squared. ax + by = c is the linear equation.
 and adding an x to an x will not make it squared. ax + by = c is the linear equation.
It can be the 2nd option because the quadratic formula is  f(x) = a + bx + c and the middle portion could cancel when adding 2 together.
 + bx + c and the middle portion could cancel when adding 2 together.
It can be option 3, because f(x) = a + bx + c plus ax + by = c could give you the resulting function f(x) = -3
 + bx + c plus ax + by = c could give you the resulting function f(x) = -3 +5
 +5
It can be option 4 because multiplying ax + by = c by ax + by = c would give you an  .
.
It cannot be option 5 because a + bx + c multiplied by a
 + bx + c multiplied by a + bx + c would give you a function with
 + bx + c would give you a function with
