Answer:

A) 2

Step-by-step explanation:

Start off with the given information. The question states that the x-int. is 4, so you should recognize that there is a point at (4,0). Plug the point into the equation.

k(4) + 2(0) + 8 = 0

Now simplify the equation.

4k + 0 + 8 = 0

Isolate the variable, make sure it's on its own side.

4k = 8

Now get the k by itself to solve the equation. Divide both sides by 4.

k = 2

The distance light travels in one year is known as a light year. A light year is equal to 5.87 × 1012 miles. The closest that Ea

pashok25 [27]

Answer:

$6.21\times 10^{-5}\ \text{light years}$

Step-by-step explanation:

The distance light travels in one year is known as a light year.

$1\ \text{light year}=5.87\times 10^{12}\ \text{miles}$

The closest that Earth ever gets to Jupiter is $3.65\times 10^8\ \text{miles}$

$3.65\times 10^8\ \text{miles}=\dfrac{1}{5.87\times 10^{12}}\times 3.65\times 10^8\ \text{light years}\\\\=6.21\times 10^{-5}\ \text{light years}$

Hence, the distance it will take light to travel from Earth to Jupiter at this distance is $6.21\times 10^{-5}\ \text{light years}$

The given equation is

Step 1 : Add 32g and 8g.

Step 2: Subtract 10 from 40.

Step 3: Divide both sides by 30, find the value of g.

The value of g is 5.

Therefore, Wilhem is correct.

What value of k makes the statement true? <br><br> k + (–4.1) = –9.7

Ugo [173]

K + (-4.1) is the exact same as saying k- 4.1, so what you have to do now is put the -4.1 in the opposite side, but with opposite sign too (+)
so k= -9.7 + 4.1
so in order to answer it you have to deduct the number with the lowest value taking in count both as positive and the sign will be the one from the highest value taking both as positive
9.7
-4.1
____
5.6
so 9.7 had a negative sign so the answer to your question is
k = -5.6
i hope i helped you
