Y + 1 = -3(x - 5)
y + 1 = -3x + 15
y = -3x + 15 - 1
y = -3x + 14 <== or f(x) = -3x + 14

Y+1= -3(x+5) in order to solve first write down the function, then find the current of the function.

Y+1=-3x-15 then this is the current of the function. Multiply the -3 times the X and the 5.

Y=-3x-14 finally this is the slope. To get the slope I added the 1 to the -15

Final answer= Y=3x+14

The speed, s, of the current in a certain whirlpool is modeled by s=300/d, where d is the distance from the center of the whirlp

JulijaS [17]

For this case we have the following equation:
s = 300 / d
Where,
s: the speed of the current in a certain whirlpool
d: the distance from the center of the whirlpool
We have then that:
If the distance from the center of the whirpool is large, the speed is small.
If the distance from the center of the whirlpool is very small, the speed tends to infinity
Answer:
Large distance, small speed.
Short distance, speed tends to infinity.

A parabola has x-axis intercepts 6 and -3, and passes through the point (1,10). Find the equation of the parabola.

ale4655 [162]

Answer:

y=-1/2 x^2+3/2 x+9

Step-by-step explanation:

The equation of parabola is:

y=ax^2+bx+c

We know that parabola has three poibts

(6,0),(-3,0) and (1,10).

So we put these three points in equation:

a*36+b*6+c=0......(1)

a*9-3b+c=0........(2)

a+b+c=10........(3)

(1)-(2) we have:

27a+9b=0.....(4)

(2)-(3) we have:

8a-4b=-10.....(5)

4(4)+9(5) we got:

180a=-90

a=-1/2

From (4) we got: b=27/18=3/2

From (3) we got: c=10+1/2-3/2=9

So equation is:

y=-1/2 x^2+3/2 x+9

You can see the picture of parabola through three points.
