Harlamova29_29 [7]

So, this problem asks us to construct an equation that relates the amount of money left to the amount of weeks that has gone by. First, let's assign variables. Let y be the amount of money left, while x is the number of weeks she receives money. The equation would be:

<em>y = 250 - 10x</em>

Write an equation of a line thru (3,-1) and (-1,-7)

Marrrta [24]

-1 - (-7) over 3 - (-1) = M

-1 + 7 over 3 + 1 = M

6 over 4 = M

6/4 = M

3/2 = M

Solve 4(x + 1) = 4x + 4

quester [9]

0= 0

both sides are equal

Step-by-step explanation:

$4(x + 1) = 4x + 4$

Expand

$4(x + 1) = 4x + 4 \\ \\ 4x + 4 = 4x + 4 \\ 4x-4x=4-4 \\ 0=0$

The position, x, of an object is given by the equation x = A + Bt +Ct2, where t refers to time. What are the dimensions of A, B,

Serjik [45]

Answer: Dimensions of A are of length [L]

Dimensions of B are of $LT^{-1}$

Dimensions of C are of $LT^{-2}$

Step-by-step explanation:

The given equation is

$x(t)=A+Bt+Ct^{2}$

Since the dimension on the L.H.S of the equation is [L] , each of the terms on the right hand side should also have dimension of length[L] to be dimensionally valid

Thus

Dimensions of A = [L]

Dimensions of Bt = [L]

$Bt=[L]\\\\$ $[B][T]=[L]$ $\\\\\therefore [B]=LT^{-1}$

Similarly

Dimensions of $Ct^{}2 = [L]$

$Ct^{2}=[L]\\\\[C][T]^{2}=[L]\\\\\therefore [C]=LT^{-2}$
