199 is the answer because the equation you use is an=a1+d(n-1). Where an (the n is actually supposed to be smaller than the a) is the nth term (a40), a1 (1 smaller than a) is the first term (4), d is the difference (5), and n is the number of the term you're looking for (40)

What is the solution of the system of linear equations below?
Kipish [7]

Answer:

A is the correct answer

Step-by-step explanation:

To get the fastest answer for these kind of questions, you just have to apply (0, -2) into either one of the 2 equations:

2 * 0 - 6 * (-2) = 12

0 - (-12) =12

0 + 12 = 12  (TRUE)

So the solution will be (0, -2)

Two trains travel directly toward each other. One of the trains travels at a rate of 12 km/h while the other travels at a rate o
Schach [20]
Write the equation of the first train: x = 12t
Write the equation of the second train: y = -20t+72, assuming the train one is at the origins when t = 0. 
Now solve the equation: 12t=-20t+72, 
32t = 72, then t = 2.25 hours. The two train meet after 2.25 hours. 
Now the equation of the <span>pigeon is like this: x = 48t. 
</span>Then for t = 2.25, we get
 x=2.25\times48=108 km

<span>The Hyde has flown 108 km when the trains meet.</span>

Y=2x+3 <br> y=3x+1 <br> solve the system of equations using substitution
Lynna [10]

Answer:

(2, 7 )

Step-by-step explanation:

Given the 2 equations

y = 2x + 3 → (1)

y = 3x + 1 → (2)

Substitute y = 3x + 1 into (1)

3x + 1 = 2x + 3 ( subtract 2x from both sides )

x + 1 = 3 ( subtract 1 from both sides )

x = 2

Substitute x = 2 into either of the 2 equations for corresponding value of y

Substituting x = 2 into (1)

y = 2(2) + 3 = 4 + 3 = 7

Solution is (2, 7 )
