Incomplete Question the complete Qs is
Which of the following is a correct equation for the line passing through the point (-2,1) and having slope m = 1/2?
a: y=1/2x+2
b: y=-2x+1/2
c: x-2y=-4
d: y-1=1/2(x+2)
Answer:
The Correct option is c. x-2y=-4
Therefore the correct equation for the line passing through the point (-2,1) and having slope m= 1/2 is
Step-by-step explanation:
Given:
point A(x₁, y₁)=(-2,1)
To Find:
Equation of Line =?
Solution:
Equation of a line passing through a points A( x₁ , y₁) and having slope m is given by the formula,
i.e equation in point - slope form
Now on substituting the slope and point A( x₁ , y₁) ≡ ( -2 , 1) we get
As required
Therefore the correct equation for the line passing through the point (-2,1) and having slope m= 1/2 is

Answer: Choice C</h3>
Explanation:
The x intercepts or roots are x = 3 and x = 5, which lead to the factors x-3 and x-5 respectively.
Multiplying out those factors gets us this:
(x-3)(x-5)
x(x-5)-3(x-5)
x^2-5x-3x+15
x^2-8x+15
Answer:
Abelito had the greater average speed
Step-by-step explanation:
Given
Bobby:
Abelito
Required:
Who had a greater average speed
Average speed (S) is calculated as:
We will make use of mph (miles per hour) as the unit of speed.
For Bobby:
Convert minute to hour
For Abelito
Convert minute to hour
By comparison: 12.5mph > 8mph
Hence: Abelito had the greater average speed
8x8 + 15x15 = y^2
64+225 = 289
take the square root of 289 which = 17
ANSWER = C. 17
Ok, so probablility of not drawing blue
total possible is 8+6+12+10=36
8 are blue so the total of not blue is 36-8=28
<span>so 28 out of 36=28/36=7/9 </span>
<span>the asnwer is 7/9 or C</span>
