Answer:

step 2 is where she made her mistake

Step-by-step explanation:

- 4x + 1 > 9 ( subtract 1 from both sides )

- 4x > 8

divide both sides by - 4 , reversing the symbol as a result of dividing by a negative quantity.

x < - 2

Does the point (0,4) make either equations y=-2x and y=x+3 true? Explain.
Nikolay [14]

Answer:

Neither

Step-by-step explanation:

To verify, we substitute the values in the equations:

y = -2x\\y = -2 \times 0\\y = 0

however, the value should be 4. Hence this equation does not satisfy the co-ordinate.

y = x+3\\y= 0+3\\y = 3

however, the value should be 4. Hence this equation does not satisfy the co-ordinate.

Express 3cm: 3m in the ratio of its simplest form​
Dmitry_Shevchenko [17]

Answer:

1cm:100cm

Step-by-step explanation:

You have to convert the ratio into the same unit (I chose cm). If there are 100cm in a metre, there will be 300cm in 3m.

That leaves you with the ratio 3cm:300cm. To simplify, divide both sides by three leaving you with 1cm:100cm
