A The point (-3,3) is a solution to this system. (2x - 4y = -18 14x – 2y = -18​

Mathematics

Answer:

True.

Step-by-step explanation:

Substitute the point into both equations to determine if it is a solution.

2x - 4y = -18

Substitute point.

2(-3) - 4(3) = -18

Multiply.

-6 - 12 = -18

Subtract.

-18 = -18

This satisfies the first equation.

4x - 2y = -18

Substitute point.

4(-3) - 2(3) = -18

Multiply.

-12 - 6 = -18

Subtract.

-18 = -18

This satisfies the second equation.

Since the point makes both of the equations equal, it is a solution to the system and therefore the answer is true.

A particle moves in a straight line so that its velocity at time
riadik2000 [5.3K]

Answer:

s(2) = 7.75

Step-by-step explanation:

given the velocity v(t) = t^3

we can find the position s(t) by simply integrating v(t) and using the boundary conditions s(1)=2

s(t) = \int {v(t)} \, dt\\ s(t) = \int {t^3} \, dt\\s(t) = \dfrac{t^4}{4}+c

we know throught s(1) = 2, that at t=1, s =2. we can use this to find the value of the constant c.  

s(1) = \dfrac{1^4}{4}+c\\4 = \dfrac{1^4}{4}+c\\c = 4-\dfrac{1}{4}\\c = \dfrac{15}{4} = 3.75

Now we can use this value of t to formulate the position function s(t):

s(t) = \dfrac{t^4}{4}+\dfrac{15}{4}\\

this is the position at time t.

to find the position at t=2

s(2) = \dfrac{2^4}{4}+\dfrac{15}{4}\\

s(2) = \dfrac{2^4}{4}+\dfrac{15}{4}\\

s(2) = \dfrac{31}{4} = 7.75

the position of the particle at time, t =2 is s(2) = 7.75
