What is the solution to this equation?

Mathematics
1 answer:
Darya [45]3 years ago
4 0

Answer:

B) x=0

Step-by-step explanation:

x +20+ 10x= 9x +20

1st step: simplify the left side by combining like terms

10x+x=11x

2nd) 11x+ 20= 9x +20

Next, you subtract 11 and 9 which is equal to 2.

2x+20=20

Now, the 20 cancels out the other twenty so your left with 2x which is not an answer, therefore the only other number is 0 to be possible.

Check: 0+20+0=20 (first expression)

0x9=0   0+20= 20 (2nd expression)

20 = 20 so this is CORRECT!!!!!!!!

Can someone help me with this math question it involves transformation
Thepotemich [5.8K]

Answer:

ABCD is reflected over the y-axis and translate (x + [-4] , y + [-4])

Step-by-step explanation:

* Lets explain the reflection and the translation

- If point (x , y) reflected across the x-axis

∴ Its image is (x , -y)

- If point (x , y) reflected across the y-axis

∴ Its image is (-x , y)

- If the point (x , y) translated horizontally to the right by h units

 ∴ Its image is (x + h , y)

- If the point (x , y) translated horizontally to the left by h units

 ∴ Its image is (x - h , y)

- If the point (x , y) translated vertically up by k units

 ∴ Its image is (x , y + k)

- If the point (x , y) translated vertically down by k units

 ∴ Its image is (x , y - k)

* Now lets solve the problem

∵ The vertices of ABCD are:

   A = (-5 , 2) , B = (-3 , 4) , C = (-2 , 4) , D = (-1 , 2)

- If ABCD reflected over the y-axis we will change the sign of the

 x-coordinate of all the points

∴ The image of A = (5 , 2)

∴ The image of B = (3 , 4)

∴ The image of C = (2 , 4)

∴ The image of D = (1 , 2)

∴ The image of ABCD after reflection over the y-axis will be at

   the first quadrant  

- The figure EHGF is left and down the image of ABCD after

 the reflection over the y-axis

∴ The image is translate to the left and down

∵ E = (1 , -2) and E is the image of A after reflection and translation

∵ The image of a after reflection is (5 , 2)

- That means 5 became 1 and 2 became -2

∵ 1 - 5 = -4

∴ The image of A after reflection translate 4 units to the left

∵ -2 - 2 = -4

∴ The image of A after reflection translate 4 units down

∴ ABCD is reflected over the y-axis and translate (x + [-4] , y + [-4])

* You can check the rest of points

# B with H

∵ B = (-3 , 4) after reflection over y-axis is (3 , 4) after translation is

   (3 + [-4] , 4 + [-4]) = (-1 , 0) the same with point H = (-1 , 0)

# C with G

∵ C = (-2 , 4) after reflection over y-axis is (2 , 4) after translation is

   (2 + [-4] , 4 + [-4]) = (-2 , 0) the same with point G = (-2 , 0)

# D with F

∵ D = (-1 , 2) after reflection over y-axis is (1 , 2) after translation is

   (1 + [-4] , 2 + [-4]) = (-3 , -2) the same with point F = (-3 , -2)

Solve for x<br><br> −6&gt;−30−4x
Mademuasel [1]

Isolate the x. Do the opposite of PEMDAS. First, add 30 to both sides

-6 (+30) > - 30 (+30) - 4x

24 > -4x

Isolate the x. Divide -4 from both sides. Note that when dividing a negative, you must flip the sign.

24/-4 > -4x/-4

24/-4 > x

-6 < x

-6 < x is your answer

hope this helps

Dave has $3000 more in a passbook account than in a money market.
Goryan [66]

The amount in the passbook account is $11,000 and the money in the money market account is $8000

Let:

a represent the unknown amount in the passbook account

b represent the unknown amount in the money market account

From the question, the following information can be gathered:

  • The money in the passbook account exceeds the amount in the money market account.

This information can be represented with this equation : a - b = 3000

  • The interest paid on the passbook account exceeds the interest paid on the money market account.

This information can be represented with this equation : 0.08a - 0.10b = 80

The two equations gotten above would be solved using simultaneous equation and the elimination method

a - b = 3000 equation 1

0.08a - 0.10b = 80 equation 2

Multiply equation 1 by 0.08

0.08 - 0.08b = 240 equation 3

Subtract equation 2 from 3

0.02b = 160

Divide both sides of the equation by 0.02

b = 8000

Substitute for b in equation 1

a - 8000 = 3000

Add 8000 to both sides

a = 11,000
