Answer:
y = (1/3)x
Step-by-step explanation:
If the y-intercept is (0, 0), then y = mx + b becomes y = mx.
Seeing that y increases by 1, going from (-3, 1) to (0, 0), and that x increases by 3, we determine that the slope, m, is 1/3.
The equation of this line is therefore y = (1/3)x.
What would you do if you ever needed to cook a chicken
if y is the time required to cook the bird and x is number of chicken lbs
y = 20x when x ≤ 6
y = 15x when x > 6
To Graph:
Have the y-axis (minutes) go by 5's since slopes of both equations are multiples of 5. The y-axis, I would suggest go to atleast 150 minutes for a 10 lbs chicken. The x-axis is in lbs and can go by 1 lb marks.
Start with the first equation where the chicken is smaller than or equal to 6 lbs. (0,0) (1,20), (2,40) (3, 60), (4,80), (5,100) to 6lbs (6,120). If the equation is EQUAL TO the point and the line will be SOLID.
for the second equation, the chicken is larger than 6 lbs. Start with x = 6 but the point will be OPEN and the line DASHED because it's NOT EQUAL TO. (6,90) (7,105) (8,120) (9,135), (10, 150) .... and on arrow to show this
Answer:
I think it might be 21.6 or just 21
Answer: x² + 5x = 3
Step-by-step explanation:Step-by-step explanation:
The rectangle has been divided into a square and three rectangles.
The area of
a square = (x)(x) = x²
a rectangle #1 = (2)(x) = 2x
a rectangle #2 = (3)(x) = 3x
a rectangle #3 = (2)(3) = 6
The area of a large rectangle is the sum of the square area and three rectangles, and is 9 cm². Therefore we have the equation:
x² + 2x + 3x + 6 = 9 subtract 6 from both sides
x² + 5x + 6 - 6 = 9 - 6
x² + 5x = 3
Answer:
<B = 18
