Caitlin = 20 laps

Hannah = 4/5 as many laps

Multiply the laps swan by Caitlin (20) by 4/5

20 x 4/5 = 80/5 = 16

Hannah swam 16 laps

F(x) = 9 + 4x f(0) = f(-1) = Find the value of x for which f(x) =6 x=
puteri [66]

Answer: x=-3/4

Step-by-step explanation:

Since we know f(x)=6, we can set it equal to the equation.

6=9+4x           [subtract 9 on both sides]

-3=4x              [divide both sides by 4]

x=-3/4

2v^2-12 =-12v <br> Would really appreciate it loves❤️
Black_prince [1.1K]

For this case we have the following equation:

2v ^ 2-12 = -12v

Rewriting we have:

2v ^ 2 + 12v-12 = 0

Dividing by 2 to both sides of the equation:

v ^ 2 + 6v-6 = 0

We apply the quadratic formula:

x = \frac {-b \pm \sqrt {b ^ 2-4 (a) (c)}} {2a}

We have to:

a = 1\\b = 6\\c = -6

Substituting:

x = \frac {-6 \pm \sqrt {6 ^ 2-4 (1) (- 6)}} {2 (1)}\\x = \frac {-6 \pm \sqrt {36 + 24}} {2}\\x = \frac {-6 \pm \sqrt {60}} {2}\\x = \frac {-6 \pm \sqrt {4 * 15}} {2}\\x = \frac {-6 \pm2 \sqrt {15}} {2}

Thus, we have two roots:

x_ {1} = - 3+ \sqrt {15}\\x_ {2} = - 3- \sqrt {15}

ANswer:

x_ {1} = - 3+ \sqrt {15}\\x_ {2} = - 3- \sqrt {15}

PLS HELP ME ASAP!!!!!!!!! ill give thanks, and five stars
docker41 [41]

Answer:

A

Step-by-step explanation:

The additive inverse property states that if we have a number a, then:

a+(-a)=0

Here, we have the equation:

2x=542

And we divide both sides by 2:

2x/2=542/2

To acquire:

x=271

So, we did <em>not</em> use the additive inverse property since we didn't add anything.

Instead, we used the<em> division property of equality</em> by dividing both sides by 2.

So, our answer is A.

And we're done!
