So, the arrow is telling us that we're going from the small rectangle to the big rectangle.

The 3 and the 7.5 are on the same side of the rectangle, right? So, let's try this backwards.

To get to 3 from 7.5, what do we divide by? (Hint: (7.5)/(3) Divide.)

The scale factor is the answer of the division, which is 2.5. We multiply 3 by 2.5 to get to 7.5.

What is the solution set of the compound inequality x+1<-2x+11<3x+5
VikaD [51]

Answer:

6/5 < x < 10/3 is the desired solution.

Step-by-step explanation:

Here, the given compound inequality is :

x + 1 < -2 x + 11 < 3 x + 5

Now, consider the first two term of the inequality, we get:

x + 1 < -2 x + 11

Subtracting 1 from both sides, we get:

x + 1  - 1 < -2 x + 11  - 1

or, x < -2x + 10

or, x + 2x < 10

or, 3 x < 10

or, x <  10/3

Similarly, considering the last two terms of the given inequality, we get:

-2 x + 11 < 3 x + 5

Subtracting 11 from both sides, we get:

-2 x + 11  - 11 < 3 x + 5 - 11

or, - 2 x < 3 x-6

or, 6 < 5 x

or, x > 6/5

Hence, combining two solutions, we get:    6/5 < x < 10/3

So, the desired value of x should be more than (6/5) but less than (10/3)

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.
