Explain what absolute value tells about -18 degrees celsius.

| -18 | = 18

Step-by-step explanation:

The value which is described as the distance of a number on the number line from the zero value (0) despite of which direction it is going is known as the absolute value.

So if we take the absolute value of a number, we always get a positive value without considering if the value was negative or positive.

Therefore, the absolute value of -18 will be positive 18.

| -18 | = 18

central angle of a triangle has the same measure as its intercepted arc.

step-by-step explanation:

y= 2x+7

changed to y= 5x +7

as slope is increased from 2 to 5

therefore it would be less steeper

so, option d) is correct
