Use the table to draw the graph of height(y-axis) against week(x-axis).
The graph is a straight line.
Find the gradient of the graph as the first step.
Gradient = (y2-y1)/(x2-x1)
= (17-12)/(4-2)
= 5/2
Use this gradient to find the equation of the line. Use one of the point from the table (e.g. (8,27)) and another general point (x,y).
∴5/2=(y-27)/(8-x)
5/2 (x-8) = y-27
(5/2)x - 20 = y-27
y=(5/2)x - 20 + 27
y = (5/2)x + 7
The answer is A
Answer:
50 degrees
Step-by-step explanation:
The diagram is attached below.
Theorem: The Exterior angle of a triangle is equal to the sum of two opposite interior angles.
By the theorem stated above:
m∠3+m∠5=m∠1
2x+20+30=3x
3x-2x=50
x=50
The value of x is 50 degrees.
Answer:
Lesser is -7
Step-by-step explanation:
x(x+4) = 21
Distribute
x^2 + 4x = 21
x^2 + 4x - 21 = 0
x^2 + 7x - 3x -21 = 0
(x+7)(x-3) = 0
x=-7, 3

1200 mL, if 300 is half of half the container, that means half is 600 mL, so 600×2=1200
