-8 is less than -4. Negative numbers reverse the logic of positive ones: since positive 8 is more than positive 4, negative 8 is less than negative 4.
Answer:y=-0.75x-1
Step-by-step explanation:firstly find gradient then use one coordinate and substitute for x and y to get the y intercept (c)
Answer: 7cm
Step-by-step explanation:
Use pythagorean theorum:
Variables:
Let the edge = A
Face diagonal (F) = 10cm
Inner diagonal (I) = sqrt(150) cm
A^2 = I^2 - F^2
A^2 = [sqrt(150)]^2 - 10^2
A^2 = 150 - 100
A^2 = 50
A = sqrt(50)
A = 7.0710678 cm
A = 7cm (to the nearest tenth)
so, length of an edge = 7cm

It took a while to get this one, and I must admit, I'm not the best at explaining anything so I'm simply going to leave the answer above to help those who are stuck.
