Answer:
D α H
k = D/H
k = 3.50
Step-by-step explanation:
Amount paid, D is directly proportional to the number of hotdogs, H
D = $3.50 per hot dog
D = $3.50 is directly proportional to 1 hotdog
Hence,
D α H
D = kH
k = proportionality constant
H = 1
3.50 = k
k = 3.50
k = D/H
Answer:
AB = sqrt 74 = 8.602
Step-by-step explanation:
simple:
a^2+b^2=c^2
5^2+7^2=74
ab=sqrt 74
Formula :
Distance between two points = √(xB−xA)2+(yB−yA)2(xB-xA)2+(yB-yA)2
Solution :
Distance between two points = √(8−3)2+(2−9)2(8-3)2+(2-9)2
= √52+(−7)252+(-7)2
= √25+4925+49
= √7474 = 8.6023
Distance between points (3, 9) and (8, 2) is 8.6023

The solution to the system of equation is (3/2, -1/2)
<h3>System of equations</h3>
Given the following system of equations as shown;
(3x+y=4 .... * 4
2x-4y=5 ..... * 1
_______________
12x+4y=16
2x-4y=5
Add both equations
12x+2x = 16 + 5
14x = 21
x = 3/2
Substitute x = 3/2 into any of the equation to have;
2x-4y=5
2(3/2) - 4y = 5
3 - 4y = 5
-4y = 5 - 3
-4y = 2
y = -1/2
Hence the solution to the system of equation is (3/2, -1/2)

Answer:
Step-by-step explanation:
here you go m = (y2-y1)/(x2-x1)
= (11-(-9))/(3-(-1))
= 20/4
= 5
