A piece of art paper is 1 1/2 inches wide and 4 inches long.What is the area of the paper
BlackZzzverrR [31]
The answer is 6 square inches because if you turn 1 and 1/2 into 3/2 you can then turn 4 into 4/1 which also turns to 8/2 so that times 3/2 = 12/2 which turns to 6/1 which is 6

The answer is 6 square inches

18) Value of b is : b\geq  8

Option A is correct.

19) Option C is correct.

Step-by-step explanation:

18) We need to find the value of b.

The given equation is:

12b-46\geq 50

Solving to find the value of b:

12b-46\geq 50\\12b\geq 50+46\\12b\geq 96\\b\geq \frac{96}{12}\\b\geq  8

So value of b is : b\geq  8

Option A is correct.

19) We need to find the correct graph of the equation:

4y-2

Solving:

4y-2

The values of y will be less than three. As y < 3 so, the circle on y is not filled.

So. Option C is correct.

Find the coordinates of the points of intersection of the graphs with coordinate axes: y=− 1/4 x+2
bearhunter [10]

Answer:


Step-by-step explanation:

Here, you can use a simple formula.

To find the point of intersection you just put x=0 or y=0.

Because, if a graph intersects x-axis, then at this point  y=0

Similarly, if a graph intersects y-axis, then at this point  x=0


So, for our given line.

y=-1/4 x +2

when , x=0 , y=-1/4 (0)+2=2

So, the graph intersects y-axis at   y=2


when , y=0 ,

then    0=-1/4 x+2

       or, 1/4 x=2

       or, x=8    [multiplying by  4]

So, the graph intersects x-axis at   x=8
