Elizabeth bought a plant and planted it in a pot near a window in her house. Let H represent the height of the plant, in inches,

adell [148]

Answer:

63.5 in

Step-by-step explanation:

y2-y1/x2-x1

28.5-21/2.5-1 = 5

y=mx+b

21=5(1)+b

21-5= 16

b=16

y=mx+b

y=5(9.5) + 16

=63.5

What is the equation of the line that passes through (-3, -1) and has a slope of 2/5? Put your answer in slope-intercept form.

Zanzabum

Hi there!

The general formula of A line in slope-intercept form is the following:
$y = mx + n$

In this formula m represents the slope of the line. Therefore, we can conclude that m = 2/5.
$y = \frac{2}{5} x + n$

We also know that the line passes through the point (-3, -1) and we can therefore substitute this coordinate into the formula of the line.
x = -3 and y = -1

$- 1 = \frac{2}{5} \times - 3 + n$

Multiply first.
$- 1 = - 1\frac{1}{5} + n$

And finally add 1 1/5 to both sides of the equation.
$\frac{1}{5} = n$

We can now switch sides.
$n = \frac{1}{5}$

Now we've found our value of n, which we can substitute into the formula of our line. Hence, in slope-intercept form, we find the following:
$y = \frac{2}{5} x + \frac{1}{5}$

What is the area of a triangle with vertices at (−4, 1) , (−7, 5) , and (0, 1) ?

Mekhanik [1.2K]

Plot the points on a graph. Connect the dots into a triangle. See that the height of the triangle is from y=5 down to y=1. So the height is 4 units.
Area of a triangle: A = (1/2)BH

You need to find the length of the base. Which is from point (-4,1) to (0,1). You can use the distance formula r just see from the graph that the base is 4 units.

A = (1/2)(4)(4)
A = 8

** Distance formula fyi
d² = (X-x)² + (Y-y)²
with points (X,Y) and (x,y)

a clerk earns $7.50 an hr, plus a commission of 5% of sales. if she works a 40 hr week and sells $6300 worth of goods, what does

ehidna [41]

Givens

Work week = 40 hours

Paid 7.50 an hour.

Sells 6300 worth of goods.

Equation

Take home pay = Sales * 5% + 7.50 * number of hours.

Sub and Solve

Take home pay = 6300 * 5% + 7.50 * 40

Take home pay = 6300 * 5/100 + 7.50 * 40

Take home pay = 315 + 300

Take home pay = 615 dollars.

Answer 615 <<<<
