$5a+c=-8a \\ 5a+c-5a=-8a-5a \\ c=-13a \\ \frac{c}{-13} = \frac{-13a}{-13} \\ -\frac{c}{13} =a$

K(x) = 6x+100 k(-5) =

kkurt [141]

Answer:

$k(-5)=70$

Step-by-step explanation:

The given function is

$k(x)=6x+100$

To find k(-5), we put x=-5 into the given function to get;

$k(-5)=6(-5)+100$

Multiply out to obtain;

$k(-5)=-30+100$

This is the same as;

$k(-5)=100-30$

This simplifies to

$k(-5)=70$

Find the value or measure below. Assume that lines that appear tangent to be tangent.

Ahat [919]

Answer:

x = 11.2

Step-by-step explanation:

hypotenuse = 8.4 (radius) + 5.6 = 14

using the Pythagorean theorem:

x² = 14² - 8.4² = 196 - 70.56 =125.44

x = √125.44 = 11.2

Hey there, Selenawebb0418!

If you look at the table, you can see that the plant grows 2 centimeters (I'm assuming it's centimeters) every 3 days.
So, the rate of the plant should be $\frac{2}{3}$ cm per day.

Thank you for using Brainly.
See you soon!
