Drag and drop each expression into the box to correctly classify it as having a positive or negative product
AfilCa [17]

Following expressions will have negative product

(\frac{1}{2})(-\frac{1}{2})\ and\ (-\frac{1}{2})(\frac{1}{2})

Following expressions will have positive product

(-\frac{1}{2})(-\frac{1}{2})\ and\ (\frac{1}{2})(\frac{1}{2})

Further explanation:

We will see at each expression one by one

First expression is:

(-\frac{1}{2})(\frac{1}{2})

In the given expression one term is positive and one term is negative. The product of negative and positive terms is negative.

Second Expression is:

(-\frac{1}{2})(-\frac{1}{2})

Both terms are negative and the product of two negative terms is positive.

Third Expression is:

(\frac{1}{2})(-\frac{1}{2})

The expression has one positive and one negative term so the product will be negative

Fourth Expression is:

(\frac{1}{2})(\frac{1}{2})

Both terms are positive so the product will also be positive

What is the y-intercept of the function, represented by the table of values below? x: -2,1,2,4,7 y: 14,8,6,2,-4
anastassius [24]

Answer:

The y-intercept is at y = 10.

Step-by-step explanation:

It will be between y = 14 and y = 7 because the corresponding x values are -2 and 1.

An increase of 3 units of x  gives a decrease of 6 units of y fro the above values.

Then an increase of 1 ( 1 to 2) in x gives decrease in y of 2 (8 to 6). The other values show the same pattern.

So very unit increase in x,  the y values change by -2.

So  from x = -2 to 0 is +2 units for x and this will be -4 units for y  so the y-intercept ( when x = 0) will be at y = 14-4 = 10

y-intercept  is (0,10).
