We know that 1 cm = 400 km
Therefore, 22 cm = x
Cross multiply:
(1)x = (400×22)
x = 8800
The result of adding 255 and 15 is;
255 + 15 = 270
Answer:
x = - 4
Step-by-step explanation:
Hi there !
if f(x) = 2x + 7 and f(x) = -1 =>
2x + 7 = - 1
2x = - 1 - 7
2x = - 8
x = - 8 ÷ 2
x = - 4
Good luck !

Answer:
-1/4
Step-by-step explanation:
When we are given two points , we can find the slope using
m = (y2-y1)/(x2-x1)
= (-9 - -6)/(3 - -9)
= (-9 +6)/( 3 +9)
= -3/12
= -1/4
