AX + B = C what is X equal to?

Mathematics
1 answer:
elena-14-01-66 [18.8K]3 years ago
5 0

Answer:

x is a variable

Step-by-step explanation:

what happens an squared plus B equals C and what I want to do is solve for a so again what we want to do is when we're taking solver a we want to isolate the variable get the variable by itself so the data that need to look at well what is happening on my variable a well you can see me as being multiplied by X and it's being added by B so I need to undo those but we got to make sure we undo them in a certain upper certain order which we call the reverse order of operations which is like the order of operations but the reverse method meaning I'm gonna undo addition or subtraction first so you can see that since my variable a is being added by B I need to undo that by subtracting B and I'll use my subtraction property of equality that's going to now subtract a 0 and then these C minus B are not like terms so I'm going to write ax is equal to C minus B now I need to solve for a so I need to look at and say alright my a is being x over X so the inverse operation of multiplying is dividing by X so therefore have a equals C minus B divided by X now sometimes you could say alright that's correct but we could also divide this X into both of these terms and I'm going to rewrite this in a different form I could say a equals C over X minus B over X alright so what I'm doing is are just dividing those through

hope this helps

To Find :-

  • The algebraic equations to solve the above problem .

Solution :-

Let ,

  • Large number = L
  • Small number = S

— According to first statement ,

  • L - S = 4
  • L - S - 4 = 0

— According to second statement ,

  • 3L + 4S = 54
  • 3L + 4S - 54 = 0 .

These equations matches with the second option b .

Option b is the correct answer.

45.3297 rounded to the nearest tenth would be?
Alex
45.3297 rounded to the nearest tenth is 45.3
3 is in the tenths place, so you look at the number to the right of it. If that number is 5 or more, you round up. If the number is 4 or less, you round down. So you round 45.3297 down to 45.3

A dilation has center (0,0). Find the image of the point L(6-8) for the scale factor 7.
rjkz [21]

Answer:

D (42,-56)

Step-by-step explanation:

Scale factor means you multiply, so you multiply (6,-8) by 7.

6 x 7 is 42 and 7 x -8 is -56. So your answer is D (42,-56).

∆ABC is translated 2 units down and 1 unit to the left. Then it is rotated 90° clockwise about the origin to form ∆A′B′C′.
RideAnS [48]

Answer:

The coordinates of image are A'(-2,1), B'(1,0) and C'(-1,0).

Step-by-step explanation:

From the figure it is clear that the coordinates of triangle are A(0,0), B(1,3) and C(1,1).

∆ABC is translated 2 units down and 1 unit to the left.

(x,y)\rightarrow (x-1,y-2)

A(0,0)\rightarrow (0-1,0-2)=(-1,-2)

B(1,3)\rightarrow (1-1,3-2)=(0,1)

C(1,1)\rightarrow (1-1,1-2)=(0,-1)

Then it is rotated 90° clockwise about the origin to form ∆A′B′C′.

(x,y)\rightarrow (y,-x)

(-1,-2)\rightarrow A'(-2,1)

(0,1)\rightarrow B'(1,0)

(0,-1)\rightarrow C'(-1,0)

Therefore the coordinates of image are A'(-2,1), B'(1,0) and C'(-1,0).
