B. -2.5
Step-by-step explanation:
This is asking for gradient. Pick any two points (x, y) then calculate the y change ÷ x change. example, (0, -5) and (-2, 0). with [0-(-5) ÷ -2-0] you get -2.5
Answer:
29.15 km
Step-by-step explanation:
Given;
George walks; 25km west and then 15 km south
Resolving the directions to x and y axis;
North and South represent positive and negative y axis.
East and West represent positive and negative x axis respectively.
25km west
Rx = -25 km
15 km south
Ry = -15 km
The resultant displacement from the house is;
R = √(Rx^2 + Ry^2)
Substituting the values;
R = √((-15)^2 + (-25)^2)
R = √(225+625)
R = √(850)
R = 29.15 km
Therefore, he is 29.15 km from house
The answer is x=9 I’ve just did this problem once you take 4x+5 you’ll get 8
Answer:
B
Step-by-step explanation:
The distance formula is
Where is the first coordinate (our case, point A(2,2)) & is the second coordinate (our case, point D(-4,-3))
<em>Plugging these in into the formula gives us:</em>
Answer choice B is closest.
