The answer would be negative due to the line pointing left. The slope would be -2/3.

Slope= -2/3

If you look at the points (3,3) you’ll see that the line meets with the point. If you move up 2 units and left 3 units, the line would meet (0,5). Which gives you your slope.

A bank manager wants to encourage new customers to open accounts with initial deposits of at least $3000. He has posters made fo

belka [17]

Incomplete question. However, let us assume

the interest rate is 5%, and
the time is 1 year.

Answer:

$150

Step-by-step explanation:

Note, the bank manager wants new customer accounts opened with at least, $3,000. Hence we have a principal, $3000. Using the simple interest formula:

$S.I= \frac{amount*rate*time}{100}$

$SI=\frac{3000*5*1}{100}$ = $150

Therefore, the minimum amount of interest a new account would make in one year is $150.

A parabolà can be drawn given a focus of (7,9) and a

NeTakaya

from the provided focus point and directrix, we can see that the focus point is above the directrix, meaning is a vertical parabola and is opening upwards, thus the squared variable will be the "x".

keeping in mind the vertex is half-way between these two fellows, Check the picture below.

$\bf \textit{vertical parabola vertex form with focus point distance} \\\\ 4p(y- k)=(x- h)^2 \qquad \begin{cases} \stackrel{vertex}{(h,k)}\qquad \stackrel{focus~point}{(h,k+p)}\qquad \stackrel{directrix}{y=k-p}\\\\ p=\textit{distance from vertex to }\\ \qquad \textit{ focus or directrix}\\\\ \stackrel{"p"~is~negative}{op ens~\cap}\qquad \stackrel{"p"~is~positive}{op ens~\cup} \end{cases} \\\\[-0.35em] ~\dotfill$

$\bf \begin{cases} h = 7\\ k = 7\\ p = 2 \end{cases}\implies 4(2)(y-7)=(x-7)^2\implies 8(y-7)=(x-7)^2 \\\\\\ y-7=\cfrac{1}{8}(x-7)^2\implies \boxed{y=\cfrac{1}{8}(x-7)^2+7}$
