2 - 3d = 4d - 19Answer and show steps​

Mathematics
1 answer:
defon3 years ago
3 0

2 - 3d = 4d - 19

Add the opposite to both sides to get the variable on the left side only.

2 - 3d = 4d - 19

   -4d    -4d

2 - 7d = - 19

Then get the terms w/o variables on the right,

2 - 7d = - 19

-2            -2

-7d = -21

Then divide by the number paired with the variable.

--7d = -21

-----    -----   ;   d = 3

-7       -7

Final answer = 3

Hope I helped :)

3w-4z=8<br> 2w+3z=-6 solve
marissa [1.9K]

Answer:

W = 0

Z = -2

Step-by-step explanation:

While simplyfying the equation, i noticed that one is 24 and the other is -24, which meant that one value is non existent, and after i found out that w = 0 imputing the reslut made that easier

I can't fail and no one has answered my previous questions so please help.

When you know your equation f(x) and they want you to find f(-4), it means that they want to know what f(x) is worth when x=-4 Therefore, you only need to plug in you x in the equation f(x)=5x-2 f(-4)=5(-4)-2 =-20-2 =-22 (B)

This problem can be readily solved if we are familiar with the point-slope form of straight lines:
y-y0=m(x-x0) ...................................(1)
where 
m=slope of line
(x0,y0) is a point through which the line passes.

We know that the line passes through A(3,-6), B(1,2)

All options have a slope of -4, so that should not be a problem.  In fact, if we check the slope=(yb-ya)/(xb-xa), we do find that the slope m=-4.

So we can check which line passes through which point:

a. y+6=-4(x-3)
Rearrange to the form of equation (1) above,
y-(-6)=-4(x-3)  means that line passes through A(3,-6) => ok

b. y-1=-4(x-2) means line passes through (2,1), which is neither A nor B
   ****** this equation is not the line passing through A & B *****

c. y=-4x+6  subtract 2 from both sides (to make the y-coordinate 2)
   y-2 = -4x+4, rearrange
   y-2 = -4(x-1)  
   which means that it passes through B(1,2), so ok

d. y-2=-4(x-1)
   this is the same as the previous equation, so it passes through B(1,2), 
   this equation is ok.

Answer: the equation y-1=-4(x-2) does NOT pass through both A and B.

PLEASE HELP 4. The Buff City Soaps in Arlington is counting how many soaps and bath bombs they sell in a given day. In total, th
Vedmedyk [2.9K]

Answer:

33 = x + (3x + 1)

x = bath bombs

So 3x is three times as many bath bombs, then the plus one makes it so that the soaps sold is more than three times the amount of bath bombs sold
