Answer:
<u>-2</u>
Step-by-step explanation:
<u>Given</u> :
- An example of a coefficient ⇒ '11' in 11kk
<u>Solving</u> :
- The coefficient is the part that precedes the variable(s)
- Therefore, on solving -k - k
- ⇒ -2k
- ⇒ <u>-2 is the coefficient</u>
<span>The equation is: 4x + y + a = 0
Point (4, -3) </span>⇒ x = 4 and y = - 3<span>
</span>⇒ 4 · 4 - 3 + a = 0
<span>
16 - 3 +a = 0
13 + a = 0
a = -13
</span>Ansver: equation is: 4x + y - 13 = <span>0 OR 4x + y = 13

Answer:
Step-by-step explanation:
The standard equation of a circle is given by:
Where (<em>h, k</em>) is the center and <em>r</em> is the radius.
We are given that the center is (4, -7) and that the radius is √(43).
So, <em>h</em> = 4, <em>k</em> = -7, and <em>r</em> = √(43). Substitute:
Simplify. Hence, our equation is:
Answer:
The probability of getting two heads and a four is 1/24
Step-by-step explanation:
The probability of getting a head upon a single toss of a coin, assuming the coin is fair is 1/2.
The probability of getting two heads upon tossing two coins together will simply be the product of the individual probabilities;
P (HH) = 1/2 * 1/2 = 1/4
On the other hand, the probability of getting a four upon rolling a six sided number cube is;
1/6
This is because the number 4 occurs only once in a total possible of 6 numbers.
Therefore, the probability of getting two heads and a four;
P (HH4) = 1/2 * 1/2 * 1/6 = 1/24 since the three events are independent.
