In order to find the distance between points, use the distance formula: √(x2-x1)^2 + (y2-y1)^2.
Answer: The correct answer is: [D]: "8" .
Step-by-step explanation:f y varies inversely with x; then y = k/x ; with "k" being the "constant" in this equation.
You can find the constant by substituting the values given: x = 16, f(x) = y = 2 ;
So, f(x) = y = 2 = k/16 ;
→ 2 = k / 16 ;
Solve for the constant; "k" ;
Multiply EACH SIDE of the equation by "16"
→ 16* (2) = (k / 16) * 16 ;
→ 32 = k ;
↔ k = 32 ;
As such, we can write the equation:
y = k/ x ; as:
→ y = 32/ x ;
Since we are given: "x = 4" ; Plug in that value; and solve for "y" ;
y = 32/4 = 8 .
y = 8 .
y = f(x) ;
So; f(x) = 8 ; which is: Answer choice: [D]: "8" .
Answer:
(x,y)=-(1,1)
Step-by-step explanation:
-2x=8-6y (divide by -2)
=> x=-4+3y
-15x=21-6y (divide by -3 for simplicity)
=>5x=-7+2y
We know that x=-4+3y, insert this into expression "5x=-7+2y"
5(-4+3y)=-7+2y
-20+15y=-7+2y
15y-2y=20-7
13y=13
y=1
Since x=-4+3y we can find x by using y=-1
x=-4+3(1)
x=-1
