La formula para sacar la pendiente:
Y2-Y1/X2-X1
Respuesta:
Y2-Y1/X2-X1= -2-(-10)/-1-(-1)
= -2+10/ -1+1= 8
R=8

Answer:
False.
Step-by-step explanation:
Because we have to isolate y and subtracting 2 will not put y alone on one side.
We have to subtract 2x in order to solve for y.
Extraneous solutions, is answers that we get because of squaring both sides of the radical equation, but in reality, they are not going to be the solutions of the given equation.
(√(4x+41))²=(x+5)²
4x+41=x²+10x+25
x²+6x-16=0
(x-2)(x+8)=0
x1=2 , x2=-8,
And now we must to check them by substitution into initial equation
√(4x+41)=x+5
1) x=2, √(4*2+41)=2+5, √49=7, 7=7 true
2) x=-8, √(4*(-8)+41)=-8+5, √9 =-3 false,
so an extraneous solution x=-8
Answer:
12500
Step-by-step explanation:
$2 are received for 1000 hits
So, $1 received for 1000/2 = 500 hits
Number of hits required to make $25
= 25*500
=12500
12 subtracted by 33 divided by 4 equals 3.75
