(-1,4)(2,3)
slope = (3-4) / (2-(-1) = -1/3....a parallel line will have the same slope
y = mx + b
slope(m) = -1/3
(4,-2)...x = 4 and y = -2
now we sub
-2 = -1/3(4) + b
-2 = - 4/3 + b
-2 + 4/3 = b
-6/3 + 4/3 = b
-2/3 = b
equation in slope int form is : y = -1/3x - 2/3
y = -1/3x - 2/3
1/3x + y = - 2/3...multiply by 3
x + 3y = - 2
x + 3y + 2 = 0 <== general form
Answer:
ab + b²-ac-bc
b(a+b) -c(a+b)
(a+b) (b-c)
Step-by-step explanation:
In these joty is the odd one.
Answer:
4 : 1 or 4 times
Step-by-step explanation:
V of sphere is
V = 4/3 π r³
then we can compare both of them dirextly
Vs : Vhs
4/3 π r³ : ½ (4/3 π (2r)³)
4/3 π r³ : ½ * 4/3 π 8r³
1 : ½ * 8
1 : 4
Vhs : Vs = 4 : 1
so the volume of hemisphere is 4 times bigger than the sphere.
Using absolute value, it is found that:
- The situation is described by the following equation:
- The markings should be between 45.5mm and 48.5mm.
---------------------------
The definition of the <em>absolute value function</em> is as follows:
----------------------------
The length should be set to 47mm with an allowance of 1.5mm, which means that <u>the absolute value of the difference between the length and 47 should be 1.5</u>, thus:
----------------------------
The solutions are:
The markings should be between 45.5mm and 48.5mm.
