Answer:
Slope = 2
y-intercept = 1
x-intercept = -0.5
Standard Form ⇒ y - 2x = 1
Step-by-step explanation:
write the equation of the line through (-2 , -3) and (0,1)
The general form of the line is y = mx + c
Where m is the slope and c is the y-intercept
The slope m = (y₂ - y₁)/(x₂ - x₁) = (1 - [-3])/(0 - [-2]) = 4/2 = 2
∴ y = 2x + c
By substitution with the point (0,1) to find c
1 = 2 *0 + c
c = 1
∴ y = 2x + 1
Or y - 2x = 1 ⇒Standard Form
Also,
See the attached figure which represents the graph of the line y - 2x = 1
Answer:
a) 10 pieces of 2/3 pound can be made.
b) 0.54 pounds of wax is left over.
Step-by-step explanation:
Total amount of clear wax available =
pounds
So, the maker has in total 4.5 pounds of wax
Now, The weight of each piece =
pounds
To find the number of pieces that can be made out of 4.5 pounds of wax,
let that number = n
So, ![n = \frac{\textrm{Total weight of the clear wax}}{\textrm{Weight of each wax}}](https://tex.z-dn.net/?f=n%20%3D%20%5Cfrac%7B%5Ctextrm%7BTotal%20weight%20of%20the%20clear%20wax%7D%7D%7B%5Ctextrm%7BWeight%20of%20each%20wax%7D%7D)
or, n = ![n = \frac{4.5}{0.66} = 6.81](https://tex.z-dn.net/?f=n%20%3D%20%5Cfrac%7B4.5%7D%7B0.66%7D%20%20%3D%206.81)
So, nearly 6 pieces can be made completely out of the clear wax
Left over amount of wax = Total weight - Weights of the pieces made
= 4.5- 6(0.66)
= 0.54 pounds
Hence, 0.54 pounds of wax is left over
16 - x = 4
16 - 12 = 4
x = 12
It is about 41.4% according to my TI-83/84 calculator.
Answer:
0 cm³
Step-by-step explanation:
the lost of water =
(5×24)/12 x 1/10 × 18000
= 10/10 × 18000 = 18,000 cm³
so, the remaining water in the tub=
18,000 - 18,000 = 0 cm³
(the tub is empty)
