Write that down the equation for the lines that is the graphs are depicted below

erastovalidia [21]

A(1,2)

Find slope of line (m)

$\\ \sf\longmapsto m=\dfrac{2-0}{1-0}$

$\\ \sf\longmapsto m=2$

Putting in y=mx+b

$\\ \sf\longmapsto y=mx+b$

$\\ \sf\longmapsto 2=2(1)+b$

$\\ \sf\longmapsto 2=2+b$

$\\ \sf\longmapsto b=2-2=0$

Equation of the line

$\\ \sf\longmapsto y=2x$

Answer:

Tommy had 56 cents in start and Loren had 7 cents in start.

Step-by-step explanation:

Let,

x be the money Tommy have.

y be the money Loren have.

According to given statement;

Tommy had 8 times more money than Loren.

x = 8y Eqn 1

Parents gave 35 cents to Loren and Tommy spent 14 cents, therefore

x-14=y+35 Eqn 2

Putting x=8y in Eqn 2

$8y-14=y+35\\8y-y=35+14\\7y=49$

Dividing both sides by 7

$\frac{7y}{7}=\frac{49}{7}\\y=7$

Putting y=7 in Eqn 1

$x=8(7)\\x=56$

Hence,

Tommy had 56 cents in start and Loren had 7 cents in start.

Answer:

$a_{15}=-268,435,456$

Step-by-step explanation:

First, find what factor each term is multiplied by to get to the next. To do this, divide the second term by the first, the third term by the second, etc

$4\div-1=-4\\-16\div4=-4\\64\div-16=-4$

The common factor is 4. Using that, you can now write the equation for the geometric sequence in the form of:

$a_n=a_1x^{n-1}$

It looks scarier than it is. aₙ is the nth term in the sequence, x is the factor, and n is the index in the sequence, that's all it is.

Plug in the information we have to get the equation for this sequence:

$a_n=(-1)(-4)^{n-1}$

Then, you can solve for the 15th term:

$a_{15}=(-1)(-4)^{15-1}\\a_{15}=(-1)(-4)^{14}\\a_{15}=(-1)(268,435,456)\\a_{15}=-268,435,456$

Basically, just raise the scale factor to the power of the term you want minus 1, then multiply that by the first number.
