Answer:
Step-by-step explanation:
(3,2),(6,3)
slope = (y2 - y1) /(x2 - x1)
slope = (3 - 2) / (6 - 3) = 1/3
y = mx + b
slope(m) = 1/3
use either of ur points...(3,2)...x = 3 and y= 2
now sub and find b, the y int
2 = 1/3(3) + b
2 = 1 + b
2 - 1 = b
1 = b
so ur equation is : y = 1/3x + 1
Answer:
36 kg
Step-by-step explanation:
Let m = mass of green tea.
The total mixture should be (18*3.5+2.6*m)/(18+m) = 2.9
The numerator is $, denominator is kg
Therefore 63+2.6m = 52.2+2.9m
0.3m = 10.8
3m = 108
m = 36
-7/12=y/-36
times both sides by -36 (-36=12*-3)
-3*-7=y
21=y
y=-21
Answer:
25p^12q^6πcm²
Step-by-step explanation:
Given the area of the circle expressed as;
A = πr^2
Given
r = 5p^6q^3 cm
Substitute into the formula
A = π(5p^6q^3 )²
A = π(25p^12q^6)
A = 25p^12q^6πcm²
hence the area of this circle in square centimeters is 25p^12q^6πcm²
Answer:
x = 7
Step-by-step explanation:
-3 + 2x = 11
(group like terms)
2x = 11 + 3
2x = 14
(divide both sides by 2 to make x stand alone)
2x/2 = 14/2
x = 7
