Answer:
b. x - 2y = 4
Step-by-step explanation:
The two points on the graph are (0, -2) and (4, 0).
Find slope:
m = (y₂ - y₁) / (x₂ - x₁)
= (0 - (-2)) / (4 - 0)
= 2 / 4
= 1 / 2
Find y intercept using anyone of the points above:
y = mx + b
-2 = 1/2(0) + b
b = -2
Use m and b to make equation of line:
y = mx + b
y = 1/2x - 2
Possible answers:
a. 4x - 2y = 4
-2y = -4x + 4
y = 2x - 2
b. x - 2y = 4
-2y = -x + 4
y = 1/2x - 2
c. -2x + 4y = -4
4y = + 2x - 4
y = 1/2x - 1

Answer:
Possible rational roots: ±1,±5.
Actual rational roots: −1,5.
Step-by-step explanation:
The trailing coefficient (coefficient of the constant term) is −5.
Find its factors (with plus and minus): ±1,±5. These are the possible values for p.
The leading coefficient (coefficient of the term with the highest degree) is 1.
Find its factors (with plus and minus): ±1. These are the possible values for q.
Find all possible values of pq: ±11,±51.
Simplify and remove duplicates (if any), these are possible rational roots: ±1,±5.
Next, check the possible roots: if a is a root of the polynomial P(x), the remainder from the division of P(x) by x−a should equal 0.
Check 1: divide x3−3x2−9x−5 by x−1.The quotient is x2−2x−11 and the remainder is −16
Check −1: divide x3−3x2−9x−5 by x+1.The quotient is x2−4x−5 and the remainder is 0
So, −1 is a root.
Check 5: divide x3−3x2−9x−5 by x−5.The quotient is x2+2x+1 and the remainder is 0
So, 5 is a root.
Check −5: divide x3−3x2−9x−5 by x+5.The quotient is x2−8x+31 and the remainder is −160
q= lead coefficient of highest term which is x^3 which has a leading coefficient of 1.
2. P=±1,±5, Q=±1. You would divide the factors of the constant by the factors of the leading coefficient.
3. Possible roots for this equation. ±1,±5.
4. Factor the equation.
x³-3x²−9x−5
x³+x²−4x²−4x-5x-5
x²(x+1)-4x(x+1)-5(x+1)
(x+1)(x²-4x-5)
(x+1)(x-5)(x+1)
5. Set all of the factors to zero and solve for x to get your rational roots to the equation.
x+1-1=0-1
x=-1
x+1-1=0-1
x=-1
x-5+5=0+5
x=5
6. Final Solution:
Possible Rational Roots: ±1, ±5

A cube root is to find a number that if multiplied three times by its self equals this number. (sorry a little confusing)
Next...
Forget about the negative for a little bit and look at it.
10*10*10=1000
Finally...
If 10 cubed is positive 1000 then -10 cubed is -1000.
So the answer is -10.

What is a circle?It is described as a set of points, where each point is at the same distance from a fixed point (called the center of a circle)
It is given that:
The intersection of a circle and a regular hexagon.
As we know, the polygon is a geometric figure with a finite number of sides in two dimensions.
On the sides or edges of a polygon, straight-line segments are joined end to end to form a closed shape. The vertices, also known as corners, are the points where two line segments meet and form an angle.
If the circle and regular hexagon will intersect on a coordinate plane then it will create two intersection points.
Thus, the intersection of a circle and a regular hexagon can be two pints option (C) two points is correct.

see what should to do buddy :
step 1-
first we have to find the gradient of the line like this:

b ( 3 , 4 )
.
step 2-
now just need one of the a or b point to put in this equation :
.
step 3-
to find the standard form of the line we have to take the y alone.
so we add the sides of the equation plus 1.
[tex]y = \frac{3}{2}x - \frac{3}{2} + 1 \\ \\ \\ y = \frac{3}{2}x - \frac{1}{2} [/tex]

Standard form of the line passing through points (1, 1) and (3, 4) is
y = (3 / 2)x - (1 / 2).
What is line?
"Line is a one dimensional figure which has only one dimension that is length no other dimension present in it."
Formula used
( x₁ , y₁) and (x₂ , y₂) are the two points through which line passes
[tex]\frac{x-x_{1} }{x_{2} -x_{1} } =\frac{y-y_{1} }{y_{2} -y_{1} }[/tex]
According to the question,
Given ,Line passes through points( 1, 1 )and (3,4)
Substitute the value in the formula to get standard form of line we get,
[tex]\frac{x-1 }{3 -1} =\frac{y-1 }{4 -1 }[/tex]
⇒3(x -1) = 2(y -1 )
⇒3x -3 = 2y -2
⇒y = (3/2)x - (1/2)
Hence, standard form of the line passing through points (1, 1) and (3, 4) is
y = (3 / 2)x - (1 / 2).

Answers
Answer:
ex:Speed (S) is the ratio of the distance (D) covered to the time (t) taken.
That is, S = D/t
Suppose Andrew ran a distance D1 in 1 hour (3600 seconds) at a Speed, say S1, we have
S1 = D1/t
We can then say he ran a distance
D1 = t × S1
= 3600S1
Similarly, let's say Karleigh ran a distance
D2 = t × S2
= 3600S2
Let us compare these two, you will notice that the bigger number between S1 and S2 is going to determine the bigger number between D1 and D2.
Let's choose random numbers for S1 and S2 for clarity, say S1 = 5, S2 = 10
D1 = 3600 × 5
= 18000
D2 = 3600 × 10
= 36000
This makes D2 bigger than D1. this is an example i found on the internet.

Answer:
The cube of twice a number.
Twice a quantity usually indicates to take two of the things in question; usually this indicates to multiply by 2. Thus "twice a number x" can be written symbolically as 2x. If this is part of a problem, say twice a number x is 6, then we can rewrite algebraically as 2x=6; dividing both sides by 2 yields x=3.
