Which expression(s) are greater than 0? Select all that apply.

Help plz with this math problem. I’m so confused

Lunna [17]

Slope-intercept form is written as y = mx + b, where m is the slope and b is the y-intercept.

From this graph we should determine two points so we can work out the slope. Let's take points (3, -4) and (6, -2).

The equation to find the slope is:

m = $\frac{y2 - y1}{x2 - x1}$

Let's substitute in our values:

m = $\frac{-2 - -4}{6 - 3}$

Remember that two negatives make a positive, let's solve for m:

m = $\frac{2}{3}$

Okay, now we have the value of m. Now we need the value of b. We can determine this by looking at the graph and looking where the line passes through the y-axis. In this graph, we can see the line pass through the y-axis at point (0, -6).

Therefore we can determine that b = -6.

Let's substitute our value for m and our value for b into the slope-intercept formula:

y = mx + b

y = $\frac{2}{3}$ x + -6

There's your final answer! I hope this helps, have a great night. :)

Set each equation to get Y by its self
Then set the equations equal to each other and solve for X

The XYZ company is seeing its value declining at a rate of 3.2% per year. If the current value is $2,300,000, what will the valu

slega [8]

Given that its value decreases by r = -3.2% (i.e decreasing means that the rate is negative) and that the current value of the company is P = 2,300,000.

The value of the company in n = 5 years is given by

$FV=P(1+r)^n \\ \\ =2,300,000(1-0.032)^5 \\ \\ =2,300,000(0.968)^5=2,300,000(0.8499) \\ \\ =\$1,954,810.81$
