Answer:

D. 52

Step-by-step explanation:

Add 85 and 45 to get 130.

6.2n-3.7n=130

Subtract 3.7 from 6.2

2.5n=130

divide 130 by 2.5 to find n

Three vertices of a rectangle are (–2, 1), (–2, –3), and (4, –3)
Tpy6a [65]
The answer is C
it's easier if you graph it
we know that the x of the unknown vertice is 4, because this is a rectangle and that vertices has to be on the same x line as the point below.
y of the unknown vertice has to be 1 because the vertice to the left needs to be on the same y line as the unknown vertice

Need help finding the equation of the line in slope intercept form
Scilla [17]

Answer:

Step-by-step explanation:

Equation: y=mx+b

m is the gradient while b is the y-intercept

Let's first find the slope (also known as the gradient) by choosing two points.  

The formula to find the slope is change in y divided by change in x.  

So two points are: (-2,0) and (0,5)

Change in y: 5-0 (we use the y-coordinates)

Change in x: 0--2 (0+2) (we use the x-coordinates)

So: 5-0= 5 and 0+2= 2 which means 5 divided by 2

Slope= 5 over two

To find the y-intercept we need to see where the line crosses the y-axis which would be at (0,5)

So: y-intercept is  5 as that's where the line crosses the y-axis.

Equation now: y= 5 over 2x +5
