Answer:
p + q = 20
Step-by-step explanation:
Given the lines intersect at (1, 1 ) then x = 1 and y = 1 make the equations true.
Consider
px = 12 with x = 1
p = 12
Consider
2x + qy with x = 1 and y = 1
2 + q = 10 ( subtract 2 from both sides )
q = 8
Hence p + q = 12 + 8 = 20
Answer:
answer is 0
Step-by-step explanation:
-4x * y * 0 lets go for x 1 y 1
-4 * 1 * 0
-4 * 0
0
In equation, let x be the number of male students
a be the number of adults
y be the number of female students.
x= 7a+1
a= x/7 -1
y= x/2 or (7a + 1)/ 2
a + b = 82, let b be the number of students.
a + (x + y) = 82
a + [7a+1 + (7a+1)/2] = 82
a + [{2(7a+1) + 7a+1} / 2] = 82
a + [(14a +2 + 7a +1) / 2] = 82
a + [(21a + 3) / 2] = 82
(2a+ 21a + 3) / 2 = 82
(23a + 3) / 2 = 82
23a + 3 = 164
23a = 164 -3
23a = 161
a = 7
x = 7(7) +1, 49+1 = 50 male students
y=x/2, 50/2, 25 female students
50(male students) + 25(female students) + 7 (adults) = 82
The correct answer is 6*10^-6 ..........................
Answer:
y = x + 6
Step-by-step explanation:
The y-intercept is (0, 6). This is where the line crosses the y-axis.
The slope is 4/4, or 1: m = 1
The equation of the line is therefore y = x + 6
