What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the first equation be = A
Now , the value of A is
x - 4y = 1 be equation (1)
Let the first equation be = B
Now , the value of B is
3x + 2y = -11 be equation (2)
Now , on simplifying both equations , we get
Multiply equation (1) by 3 , we get
3x - 12y = 3 be equation (3)
Subtracting equation (2) from equation (3) , we get
-12y - 2y = 3 - ( -11 )
-14y = 14
Divide by -14 on both sides of the equation , we get
y = -1
So , the value of y = -1
Substitute the value of y in equation (1) , we get
x - 4y = 1
x - 4 ( -1 ) = 1
x + 4 = 1
Subtracting 4 on both sides of the equation , we get
x = -3
So , the value of x = -3
Hence , the value of x is -3 and value of y is -1

Step-by-step explanation:
The function g(t) = - 16t2 + vt + h represents the height of an object, g, in feet, above the ground in relation to the time, t, in seconds, since the object was thrown into the air with an initial velocity of v feet per second at an initial height of h feet.
A model rocket is launched off the ground at an initial velocity of 80 feet per second.
Part A: Write a function that can be used to describe the flight of the model rocket.
Answer:
g(t)= -16t^2 +80t
Step-by-step explanation:Should be
A function is a relationship between inputs where each input is related to exactly one output.
The function that can be used to describe the flight of the model rocket is
g(t) = -16t² + 80t.
What is a function?A function is a relationship between inputs where each input is related to exactly one output.
Example: f(x) = 3x + 1 is a function
x = 1, f(1) = 3 + 1 = 4
We have,
A function that represents the height of an object.
g(t) = -16t² + vt + h
t = time in second
v = Initial velocity per second
h = Initial height
Initial velocity:
v = 80 feet per second
A model rocket is launched off the ground.
This means,
h = 0
Now,
Putting v = 80 and h = 0
g(t) = -16t² + vt + h
g(t) = -16t² + 80t + 0
g(t) = -16t² + 80t
Thus,
The function that can be used to describe the flight of the model rocket is
g(t) = -16t² + 80t.

Answer:
Step-by-step explanation:
(a)
well since they can lay 7 miles of track every day, the formula i make for the amount of track there is left to lay is:
L=196-Ld
where l is the length of track remaining, L is the length of track they can lay in one day and d is the number of days.
so we replace L for 7 and d for 17 and we get:
L=196-7x17
which works out to be 77 miles of track remaining to lay.
(b)
well since we want them to have 0 length of track remaining, and they can lay 7 miles of track a day, we can work out d. let's give the formula a bash to get:
d=196-l/L
we then replace l with 0 and L with 7 and get:
d=196/7
which works out to be 28. so it will take 28 days or 4 weeks for the railroad crew to lay 196 miles of track.
