Which of these parts of a lease is most similar to a mortgage ?

Natasha2012 [34]

The parts of a lease that are most similar to a mortgage are C. THE TERM OF LEASE AND THE MONTHLY RENT.

The term of lease is at least 1 year. And lease payments are usually made monthly.

Mortgage, be it real property or chattel mortgage, is for a period of at least 5 years and monthly payment must be made. The payment covers the principal amount loaned as well as the corresponding interest on the loaned amount.

As a salesperson at Roaring Waves Beach Supplies, Carissa receives a monthly base pay plus commission on all that she sells. If

Pani-rosa [81]

Base pay + (rate * sales) = total pay

b + r(400) = 388
b + r(700) = 454

b = 388 - 400r
now sub into 2nd equation
388 - 400r + 700r = 454
-400r + 700r = 454 - 388
300r = 66
r = 66/300
r = 0.22...22% is the rate

substitute for r
b + 400r = 388
b + 400(0.22) = 388
b + 88 = 388
b = 388 - 88
b = 300

so ur equation is : y = 0.22x + 300
y = 0.22(2600) + 300
y = 572 + 300
y = 872......so her salary when selling $2600 worth of stuff is $872

PLEASE HELP!! What is the value of x?

Black_prince [1.1K]

To find x, first we'll split the triangle in two right triangles.

The first triangle will be the one with sides (8,x+4,y) and the second triangle will be the one with sides (12,2x+1,y).

As you can see, these two triangles share the side 'y'.

To solve we'll do the following; first solve for 'y' by applying the Pythagorean theorem in the second triangle, and finally solve for 'x' applying Pythagorean theorem in the first triangle.

From the second triangle (12,2x+1,y) we solve for 'y' by writing:
$y^{2}=12^{2}- (2x+1)^{2}=144-4 x^{2} -4x-1=$

Now that we know 'y^2' we apply Pythagorean Theorem in the first triangle (8,x+4,y)
$8^{2}= (x+4)^{2}+ y^{2}= (x^{2}+8x+16)+(143-4 x^{2} -4x)$
$64=159-3 x^{2} +4x$

Now you solve the quadratic equation, you'll get a positive and negative value; as this are lengths, you take the positive and get:

$x= \frac{19}{3}$

Need help ASAP! Will Give Brainliest!

baherus [9]

Answer:

A) To plot equations in point-slope form, pick one and let x = 0, then solve for y (or -4). That gives you point 1 (0,-4). Then let y = 0 and solve for x (or 2/3). That gives you a second point (2/3,0). Plot the two points and draw the line. Repeat for the second equation (points are (0,-3) and (3/5,0)). Where the lines cross is the solution for both equations.

B) point (1,2) fits both equations.

Step-by-step explanation:

Or solve by brute force...

The solution is where the same X,Y point fits both equations, or Y1 = Y2 and X1 = X2. So the equations in point-slope form (already in point-slope form) equal to each other, solve for X and plug that back into either of the equations to find Y.

6X - 4 = 5X -3

X = 1 so

y = 6X - 4

Y = 6 - 4

Y = 2
