x + 1 x < 1
Answer:
504 millimeters (or 50.4 cm)
Step-by-step explanation:
Width of key in student calculator = 14 millimeter (1.4 cm)
Width of key in demonstration calculator = 2.8 cm
Thus, the demonstration calculator's dimensions are twice that of students' (in cm)
Also given, student calculator height as 252 millimeters (25.2 cm)
Thus demonstration calculator height will be twice of that = 50.4 cm (or 504 millimeters)
IF USING GEOMETRY...
x-axis = (x, -y)
Because the x does not have a negative sign the number DOES NOT change to its opposite form, but because the y has a negative sign the number DOES changes to its opposite form (from negative number to positive.)
So... if we use the formula of x-axis, which is (x, -y), the coordinates (-7,-3) would change to (-7, 3)
ANSWER (-7, 3)
