Answer:

C

also known as:

A=6 B=-15

Step-by-step explanation:

The answer is C because when you plug in those numbers (6 and -15) into the original equation, they make the same line/equation, and to have infinitely many solutions, the lines have to be equal.

Hope this helps!

A dolphin dives down into the ocean and resurfaces along a path that is modeled by x2 – 8x + 4y = 0, where the distances are in
larisa86 [58]

the dolphin is 8 ft from its starting point (option A)

Explanation:

The path model:

x^2\text{ - 8x + 4y  = 0}

Considering the water's surface as the starting point, the value of y = 0

And x = distance from its starting point

We substitute for y in the model:

\begin{gathered} x^2\text{ - 8x + 4(0) = 0} \\ x^2\text{ - 8x = 0} \end{gathered}

Then we find the values of x:

\begin{gathered} x^2\text{ - 8x = 0} \\ x(x\text{ - 8) = 0} \\ x\text{ = 0 or x- 8 = 0} \\  \\ x\text{ - 8 = 0} \\ x\text{ = 8} \end{gathered}

From our result, the dolphin is 8 ft from its starting point (option A)

A cylindrical test tube holds 6π cm of liquid when filled to the 6cm mark what is the diameter of the test tube to the nearest h
DanielleElmas [232]

Answer:

2cm

Step-by-step explanation:

Given data

Capacity/volume of liquid held=  6π cm^3

Height= 6cm

Required

The diameter d of the tube

let us apply the expression for the volume of cylinder

V=πr^2h

6π=πr^2*6

6=r^2*6

r^2= 6/6

r^2=1

r= √1

r=1cm

Hence the diameter d = 2r= 2*1= 2cm
