Answer:
y = -5/4x - 8
Step-by-step explanation:
Slope m = (y2-y1)/(x2-x1)
m = (-3 - 2)/(-4 - -8) = -5/4
Given (-8,2)
y = mx + b
2 = -5/4(-8) + b
2 = 10 + b
b = -8
y = -5/4x - 8
Answer:
Below in bold.
Step-by-step explanation:
(a) Using the Pythagoras theorem:
30^2 = 21^2 + p^2
p^2 = 30^2 - 21^2 = 459
p = √459
= 21.4 cm to nearest tenth.
(b) cos P = 21/30 = 0.70
m < P = 45.57 degrees to nearest hundredth.
Answer:
12
Step-by-step explanation:
1) 5+19−6(5+1−4)
2)5+19−6(6−4)
3)5+19−(6)(2)
4)5+19−12
5) 5+7
6) 12
Step-by-step explanation:
Total dogs and chickens = 14
If there are 10 dogs = 10 x 4 = 40 legs
If there are 4 chickens = 4 x 2 = 8
So 40 + 8 = 48
