J=14, k=j+8, l=2m, m=k-7
j=14, k=(14+8), l=2(k-7), m=(14+8)-7
j=14, k=22, l=2(22-7), m=22-7
j=14, k=22, l=30, m=15
And we are told that j+k+l+m+n=100, using j,k,l, and m found above:
14+22+30+15+n=100 combining like terms on left side
81+n=100 subtract 81 from both sides
n=19
So Nicky scored 19 points.
Because six times six is 36 and when u sqaure a number u times it by itself
Answer:
1) m = negative StartFraction 10 over 4 EndFraction
2) m = negative five-halves
3) m = ![-\frac{7}{4} - \frac{3}{4}](https://tex.z-dn.net/?f=-%5Cfrac%7B7%7D%7B4%7D%20-%20%5Cfrac%7B3%7D%7B4%7D)
Step-by-step explanation:
<u>The given equation is:</u>
=> ![\frac{3}{4} +m = -\frac{7}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B4%7D%20%2Bm%20%3D%20-%5Cfrac%7B7%7D%7B4%7D)
Subtracting 3/4 to both sides
=> m = ![-\frac{7}{4} - \frac{3}{4}](https://tex.z-dn.net/?f=-%5Cfrac%7B7%7D%7B4%7D%20-%20%5Cfrac%7B3%7D%7B4%7D)
=> m = ![\frac{-10}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B-10%7D%7B4%7D)
=> m = ![-\frac{5}{2}](https://tex.z-dn.net/?f=-%5Cfrac%7B5%7D%7B2%7D)
The time taken for the population of the pig to reach 1000 will be almost four years.
<h3>What is a function?</h3>
A function is a statement, rule, or law that establishes the connection between two variables. In mathematics, functions are everywhere and are necessary for constructing physical connections.
Six guinea pigs are released in an area with no natural predators.
The guinea pig population quadruples every year.
Write a function P that represents the guinea pig population at a given time T measured in years.
Then the function will be
![\rm P = 6 (4)^T](https://tex.z-dn.net/?f=%5Crm%20P%20%3D%206%20%284%29%5ET)
Then the inverse function of P will be
![\rm T = 6 (4)^P\\\\\\P \ln 4 = \ln \left (\dfrac{T}{6} \right )\\\\\\P = \dfrac{\ln (T/6)}{\ln 4}](https://tex.z-dn.net/?f=%5Crm%20T%20%3D%206%20%284%29%5EP%5C%5C%5C%5C%5C%5CP%20%5Cln%204%20%3D%20%5Cln%20%5Cleft%20%28%5Cdfrac%7BT%7D%7B6%7D%20%5Cright%20%29%5C%5C%5C%5C%5C%5CP%20%3D%20%5Cdfrac%7B%5Cln%20%28T%2F6%29%7D%7B%5Cln%204%7D)
Then the time taken for the population of the pig to reach 1000 will be
![\rm 1000 = 6 (4)^T\\\\\\166.667 = 4^T\\\\\\T = 3.69 \\\\\\T \approx 4 \ years](https://tex.z-dn.net/?f=%5Crm%201000%20%3D%206%20%284%29%5ET%5C%5C%5C%5C%5C%5C166.667%20%3D%204%5ET%5C%5C%5C%5C%5C%5CT%20%3D%203.69%20%5C%5C%5C%5C%5C%5CT%20%5Capprox%204%20%5C%20years)

Substitute:
You are going to substitute each answer choice into your equation.
-2x - y = -7
Let's take the first choice
(3,1)
x y
-2(3) - 1 = -7
-6 - 1 = -7
-7 = -7
The ordered pair that is a solution to -2x - y = -7 is (3, 1).
Answer - (3, 1)
Hope this Helps!!
