Find the slope of the line that is parallel and perpendicular to the following equation.
2x - y = -2
Answers
Answer:
slope in parallel = 2
slope in perpendicular = [tex]\sf \bold{-\frac{1}{2} }[/tex]
y intercept = (0, 2)
Rewrite in slope intercept form:
slope intercept form: y = mx + b || where "m" is slope and "b" is y-intercept
2x - y = -2-y = -2 - 2xy = 2x + 2 ** identify m and b _ _ _ m = 2, b = 2 **y-intercept: 2 --- as "b" is [+2] then x will be always 0 at y-intercept
y-intercept coordinates: (0, 2)slope is same when parallel
slope in parallel = 2 --- as "m" is [+2]perpendicular slope is negative reciprocal of the parallel slope
m1 is the parallel slope and m2 is the perpendicular slopem1 * m2 = -12 * m2 = -1m2 = -1/2 --- this is the slope of perpendicular lineConvert to slope intercept form
2x-y=-2y=2x+2Slope:-
m=2Parallel lines have equal slope
Slope of the perpendicular line=-1/2
A passenger train left new york and traveled north while a freight left from the same place, and the same time and traveled south. After traveling for 6 hours the traines were 720 miles apart. if the passenger train was traveling at 80mph, how fast was the freiht train traveling.
Answers
The freight train was traveling at 40 mph.
Let's use the formula for distance:
distance = rate x time
We know that the two trains are moving away from each other, so we can add their distances to get the total distance between them:
distance = distance traveled by passenger train + distance traveled by freight train
Since they started at the same time, the time traveled by both trains is the same, so we can write:
distance = 80 mph x time + rate of freight train x time
Using the given information, we can write:
720 = 80 x 6 + rate of freight train x 6
Simplifying:
720 = 480 + 6(rate of freight train)
240 = 6(rate of freight train)
rate of freight train = 40 mph

Answers
The circumference of the smaller circle is C = 2*pi*x/3.
We have given that radius ob measures x units
What is the formula for the circumference of the circle ?circumference of the circle is given by,
[tex]C = 2\times \pi \times R[/tex]
where pi = 3.14
R= radius
we have two circles, A and B, where B is the larger circle and A is the smaller circle.
We know that,The circumference of B is 3 times the circumference of A.
The radius of circle B is OB = x
The radius of circle A is OA
We want to find an expression of OA.
The circumference of circle B is given by
[tex]C(B) = 2\times \piOB = 2\times pi\times x[/tex]
The circumference of circle A is given by
[tex]C(A) = 2\times\pi\times OA[/tex]
we know that the circumference of circle B is 3 times the circumference of circle A,
[tex]C(B) = 3\times C(A)[/tex]
replacing the equations for the circumferences
[tex]2\times\pi\times x = 3\times (2\times pi\times OA)[/tex]
We have divide both sides by [tex]2\pi[/tex]we get:
[tex]x = 3\times OA[/tex]
Now we want to solve this for OA, then we need to isolate it,
[tex]x/3 = OA[/tex]
We can conclude that the radius of the smaller circle is equal to x/3.
Then the circumference of circle A is

There are 8 red marbles, 2 green marbles, and 5 blue marbles in a bag. Marbles are replaced after each draw. What is the probability that the first marble drawn is red and the second marble drawn is green?
Answers
Answer:
[tex]\frac{16}{225}[/tex]
Step-by-step explanation:
When attempting probability problems we want to figure out the chances of something happening. This turns into something like:
[tex]\frac{\text{marble drawn}}{\text{total marbles}}[/tex]
In this case we have 8 red marbles, 2 green marbles, and 5 blue marbles in a bag. That brings us to a total of 15 marble.
Since we want to first draw a red marble the chance of that happening would be:
[tex]\frac{8\text{(the marble drawn)}}{15\text{(total # of marbles)}}[/tex]
Now we replace the marble as stated in the problem so we then draw the next marble, which is green.
[tex]\frac{2\text{(the marble drawn)}}{15\text{(total number of marbles)}}[/tex]
All that's left is to multipy the values we got:
[tex]\frac{8}{15} *\frac{2}{15}=\frac{16}{225}[/tex]
That's our answer.

The values of angles are written below,
a° = 121°
b° = 53°
c° = 87°
d° = 72°
What is the angle of the chord?The Inscribed Angle Theorem: This theorem states that the measure of an inscribed angle in a circle is equal to half the measure of the intercepted arc.
In other words, if an angle is formed by two intersecting chords in a circle, the measure of the angle is equal to half the sum of the measures of the arcs intercepted by the angle.
The values of angles are calculated as,
a = (2 x 108 ) - 9 5
a = 121°
b = 360 - ( 121 + 95 + 91 )
b = 53°
c = (121 + 53 ) / 2
c = 87°
d = ( 91 + 53 ) /2
d = 72°
Therefore, the values are a = 121°, b = 53°, c = 87°, and d = 72°.

Answers
The first step for factoring is 3w(x + y) - 4z(x + y). The correct option is (A).
What is an Algebraic expression?An algebraic expression can be obtained by doing mathematical operations on the variable and constant terms.
The variable part of an algebraic expression can never be added or subtracted from the constant part.
The given algebraic expression is as below,
3wx + 3wy - 4zx - 4zy
In order to factorize it find the common factors for the group terms such that one of the factors is common for both the groups as follows,
3wx + 3wy - 4zx - 4zy
Take (3wx + 3wy) and (- 4zx - 4zy) as two groups.
The factor form for (3wx + 3wy) is 3w(x + y).
And, for (- 4zx - 4zy) it is -4z(x + y).
Thus, the given expression can be written as,
3wx + 3wy - 4zx - 4zy
= 3w(x + y) - 4z(x + y)
Hence, first step when factoring the given expression is 3w(x + y) - 4z(x + y).

65° + C = 180° or 65° + A = 180°, They are supplementary angles that are linear pair that add up to 180°.
A = C = 115°
B° = 65° Vertical Angles meaning they are equal to each other.
D and E are equal to cheat other since the lines on the sides mean that are isosceles.
