Please please help me with this

Mathematics
1 answer:
Pavlova-9 [17]3 years ago
5 0

Answer:

140

Step-by-step explanation:

Area of a rhombus = GE * HF / 2

Since, ED = 10,  GE = 2* ED. SO, GE = 20

Since, FD = 7, HF = 2*FD. SO, HF = 14

So, 20 * 14/2

=> 10 * 14

=> 140

Statistics:
Dima020 [189]

Answer:

Step-by-step explanation:

a) sub in 600 for 6

600-25/40 =14.375

b) switch x and y

x=y-25/40

Solve for y

40x=y-25

y=40x+25

c)Plug in 2.5 for z(x)

2.5= x-25/40

100=x-25

x=125

Identify the slope (m) and y-intercept (b) of each linear equation.<br> 52. 3x+4y=24
nekit [7.7K]

Answer:

Step-by-step explanation:

  [1]    3x - 4y = -24

  [2]    -x - 16y = -52

Graphic Representation of the Equations :

   -4y + 3x = -24        -16y - x = -52  

 

Solve by Substitution :

// Solve equation [2] for the variable  x

 [2]    x = -16y + 52

// Plug this in for variable  x  in equation [1]

  [1]    3•(-16y+52) - 4y = -24

  [1]     - 52y = -180

// Solve equation [1] for the variable  y

  [1]    52y = 180

  [1]    y = 45/13

// By now we know this much :

   x = -16y+52

   y = 45/13

// Use the  y  value to solve for  x

   x = -16(45/13)+52 = -44/13

Solution :

{x,y} = {-44/13,45/13}

Plz help ill give brainlist to you

Hey there!

To start, first set up your expression like this:
(5x+17)-(3x-4)

You must set up your expression like this since in subtraction, order matters and the problem asks for the difference between the first plant and the second plant, respectively, meaning you must follow in this order.

Now, simplify:
(5x+17)-(3x-4)
(5x+17)+(-3x+4)
2x+21

Therefore, the difference the two companies would be 2x+21.

IT'S URGENT PLEASEE<br><br> What is the slope of a line perpendicular to the line 2y = 3x - 10?
belka [17]
<h3>Answer:  perpendicular slope is -2/3</h3>

=================================================

Work Shown:

Solve the given equation for y

2y = 3x - 10

y = (3x-10)/2 ..... divide both sides by 2

y = (3x)/2 - 10/2

y = (3/2)x - 5

The equation is in y = mx+b form with m = 3/2 as the slope.

The perpendicular slope is -2/3 because we flip the fraction and the sign from positive to negative.

Note how multiplying the original slope 3/2 and the perpendicular slope -2/3 leads to -1

(3/2)*(-2/3) = -1

This is true for any pair of perpendicular lines, assuming neither line is vertical.
