Answer:

$4501.51

Step-by-step explanation:

Because you're compounding annually, which is only once per year, you can use a simple formula:

$A(t)=P(1+r)^{t}$

Filling in our info gives us

$A(t)=3100(1+.055)^7$

Do the adding inside the parenthesis and then raise 1.055 to the 7th power to get

A(t)= 3100(1.454679161)

A(t)= $4509.51

Hey there!

$\bold{1\frac{2}{6}-4\frac{4}{6}}$

$\bold{1\frac{2}{6}=1\frac{1}{3}=\frac{4}{3}}$
$\bold{4\frac{4}{6}=4\frac{2}{3}=\frac{14}{3}}$
Problem becomes: $\bold{\frac{4}{3}-\frac{14}{3}}$
To solve our new problem $\uparrow;\downarrow$
$\bold{4-14=-10}$
The $\bold{3's}$ stay the same because the same
$\bold{\rightarrow=\frac{-10}{3}}$
$\boxed{\boxed{\bold{Answer:\frac{-10}{3} (or)=-3\frac{1}{3}}}}$

Good luck on your assignment and enjoy your day!

Please help guys I’m really struggling

Answer: y = -4x - 4

Step-by-step explanation:

Point slope form: y - y1 = m(x - x1)

Plug in y1 and x1, and m. M is the slope, x1 and y1 are the values for a coordinate. You don't need to plug anything in for y or x, just y1 and x1.

First, find the slope. To find the slope, use this "formula" : $slope=\frac{rise}{run} =\frac{y1-y2}{x2-x1}$

Find two coordinate points. Let's use (-2,4) and (0,-4). Based on this, we know that y1 is 4, y2 is -4, x1 is -2, and x2 is 0. Plug these into the formula:

$\frac{4--4}{-2-0} =\frac{4+4}{-2} =\frac{8}{-2}=-4$

Then, pick any point to plug into the equation. Let's use (0,-4)

Finally, plug everything into the equation:

y - - 4 = -4(x - 0)

y + 4 = -4x

y = -4x - 4
