I need to graph -3x+2y=4

Mathematics
1 answer:
hammer [34]4 years ago
5 0
-3x + 2y = 4
2y = 3x + 4
y = 3/2x + 2

so ur slope is 3/2 and ur y int is (0,2)

ur x int can be found by subbing in 0 for y and solving for x
-3x + 2(0) = 4
-3x = 4
x = -4/3...so ur x int is (-4/3,0)

so plot ur x and y intercepts (0,2) and (-4/3,0)....and start at (-4/3,0) and since ur slope is 2, go up 2 spaces and to the right 1 space, then up 2 spaces, and to the right 1 space...keep doing this and u should cross the y axis at (0,2)

I need help please the friends would greatly appreciate it. plotted in the complex plane ... :)
zlopas [31]
Attached is a picture showing the plot in the plane.
Note that for a complex number ,  x + iy.
The real part of the number is put on the x axis and the imaginary part is put on the y axis.

So plotting:
A = 4 + 1i
B = 9 + 7i
C = 5 + 8i
 
See picture.

A rectangle has a length of 10 cm and a width of 7 cm. What is its perimeter?
spin [16.1K]

Answer:

34 cm

Step-by-step explanation:

Keep in mind that the perimeter of a rectangle is the sum of the measures of its sides. This means that the sum of the longer sides and the shorter sides is the perimeter of the rectangle.

Let "L" represent the longer side (length) of the rectangle and "S" represent the shorter side (width) of the rectangle.

⇒ Perimeter of rectangle = L + S + L + S

⇒ Perimeter of rectangle = 2(L) + 2(S)

⇒ Perimeter of rectangle = 2(L + S)

Now, let's substitute the length and the width in the perimeter and simplify.

⇒ Perimeter of rectangle = 2(10 + 7)                                                [L = 10; S = 7]

⇒ Perimeter of rectangle = 2(17)

⇒ Perimeter of rectangle = 34 cm

Write these numbers in order from least to greatest. ( 3-3/10), (3.1) , (3-1/4)
Orlov [11]

Our three numbers are...

3 3/10 = 3.3

3.1

3 1/4 = 3.25

So, if we order those from least to greatest, we have...

3.1, 3.25, 3.3

which, in the forms given, is...

3.1, 3-1/4, 3-3/10
