Step-by-step explanation:
Factor the numerator, difference of squares
[tex]\frac{(x-3)(x+3)}{x-3}[/tex] ( cancel x- 3 on numerator/ denominator )
= x + 3
limit as x → 3 = 3 + 3 = 6
1/2x - 7 = 1/3 (x- 12)
Answer:
x = 18
Step-by-step explanation:
1/2x - 7 = 1/3 (x- 12)
Multiply both sides by 3
3 * 1/2x - 3 * 7 = 3 * 1/3 (x - 12)
3/2x - 21 = x - 12
Collect like terms
3/2x - x = 21 - 12
1/2x = 9
Multiply both sides by 2
x = 2 * 9
x = 18
Answer:
x = 18

Answer:
y-9=7(x+5)
Step-by-step explanation:
Point-Slope form is
[tex]y-y_{1} =m(x-x_{1} )[/tex]
where m equals the slope of the line and y1 and x1 represent the y and x coordinates of one of the points on that line.
First, let's find the slope (change in y divided by the change in x):
[tex]\frac{9-(-5)}{-5-(-7)} =\frac{14}{2} =7[/tex]
Now, let's choose any one of the two points, I'll pick (-5,9), but (-7, -5) also works.
Substitute in the y value (in this case 9) for y1 and substitute the x value (in this case -5) for x1
We can also substitute the slope, m which we know is 7.
y-9=7(x-(-5)
y-9=7(x+5)
can someone please help me with this? (i will mark brainliest) (LMNP is rotated 180 degrees clockwise around the origin. what are the coordinates of L?)
Answer:
L's coordinates would go from being (x,y) to (-x, -y)
Step-by-step explanation:
So like, if L's coordinates were (5, 7) after rotation it would be (-5, -7)
If you were working backward and with L' being rotated you would do (-5, -7) change the sign and do (5,7) for L
Consenquently if you had a negative to begin with- L (-3, -4) L' would be the opposite sign and be (3,4)

The equivalent expressions for [tex]\sqrt{\frac{36a^8}{225a^2} }[/tex] are A, B and E.
What is Square Root?Square root of a number is the value such that the value when multiplied to itself two times gives the original number.
It is denoted by the symbol √.
Given expression is [tex]\sqrt{\frac{36a^8}{225a^2} }[/tex].
There are five expressions in the left.
A. [tex]\sqrt{\frac{2(2)(3)(3)(a)(a)(a)(a)(a)(a)(a)(a)}{3(3)(5)(5)(a)(a)} }[/tex]
Here we have to multiply the terms in the numerator as well as in the denominator.
2(2)(3)(3) = 36 and 3(3)(5)(5) = 225
So this expression is equivalent to the given [tex]\sqrt{\frac{36a^8}{225a^2} }[/tex].
B. [tex]\sqrt{\frac{4a^6}{25} }[/tex]
We know that, greatest common factor of 36 and 225 is 9.
36/9 = 4 and 225 / 9 = 25
Also a⁸ / a² = a⁸⁻² = a⁶
So this is also an equivalent expression.
C. [tex]\frac{6}{25} \sqrt{ \frac{a^8}{a^2} }[/tex]
This is not equivalent since √225 = 15, not 25.
D. [tex]\frac{6}{15} a^4[/tex]
This is also not equivalent since [tex]\sqrt{ \frac{a^8}{a^2} }[/tex] = [tex]\sqrt{a^6}[/tex] = a³, not a⁴.
E. [tex]\frac{2}{5} a^3[/tex]
This is equivalent expression since √36 = 6 and √225 = 15.
[tex]\sqrt{\frac{36a^8}{225a^2} }[/tex] = [tex]\frac{6}{15}[/tex] [tex]\sqrt{ \frac{a^8}{a^2} }[/tex] = [tex]\frac{2}{5}[/tex] [tex]\sqrt{a^6}[/tex] = [tex]\frac{2}{5} a^3[/tex]
Hence the equivalent expressions are A, B and E.

A certain pipe can be used to fill a pool with water in 2 hours. A second pipe can be used to fill the pool in 4 hours. How long does it take to fill the pool when both pipes are used at the same time?
Answer:
1 1/3 hours
Step-by-step explanation:
Pipe 1 alone:
fills the pool in 2 hours
in 1 hour, it fills 1/2 of the pool
Pipe 2 alone:
fills the pool in 4 hours
in 1 hour, it fills 1/4 of the pool
Pipe 1 and Pipe 2 working together:
fill the pool in x hours
in 1 hour, they fill 1/x of the pool
Working together, in 1 hour the two pipes fill 1/2 + 1/4 of the pool.
Working together, in 1 hour the two pipes fill 1/x of the pool.
Therefore,
1/2 + 1/4 = 1/x
2/4 + 1/4 = 1/x
3/4 = 1/x
x = 4/3
x = 1 1/3
Answer: 1 1/3 hours

Write the equation of the line which passes through (1, 2) and with slope of −1/3
in standard form.
Answer:
x + 3y = 7Step-by-step explanation:
The equation of a line which passes through (x₁, y₁) and with slope of m in point-slope form:
y - y₁ = m(x - x₁)
m = -¹/₃
(1, 2) ⇒ x₁ = 1, y₁ = 2
Therefore, the equation of the line which passes through (1, 2) and with slope of −1/3 in point-slope form:
y - 2 = -¹/₃(x - 1)
y - 2 = -¹/₃x + ¹/₃ {add ¹/₃x to both sides}
¹/₃x + y - 2 = ¹/₃ {add 2 to both sides}
¹/₃x + y = 2¹/₃ {multiply both sides by 3}
x + 3y = 7

5. A robot that picks up tennis balls is on a straight path from (8,6) toward a ball at (-10,-5). The robot picks up a ball at (-10,-5) and then turns 90° right. What are the coordinates of appoint that the robot can move toward to pick up the last ball?
Answer:
Step-by-step explanation:
so this question is about perpendicular lines. keep in mind that a perpendicular line has a reciprocal slope of opposite sign, from the line it's perpendicular to . :) okay so what is that line the robot is on, let's first
find the slope , m
m = (y2 - y1) / ( x2 - x1)
P1 = (8,6) in the form ( x1,y1)
P2= (-10,-5) in the form (x2,y2)
then
m = (-5-6) / (-10-8)
m = -11 / -18
m = 11/ 18
and then lets use the point-slope formula with the slope we just found and one of the given points, let's pick P1
y-6 = 11/18(x-8)
y = 11/18x - 88/18 + 6
y = 11/18x -88/18 + 108/18
y = 11/18x + 20/18
now let's take the reciprocal of the slope and change the sign, then we have
y = - 18/11x +20/18 ( coordinates robot can move on )
on the graph I'm attaching the green line is the one where the robot first moves, then the purple one.. is the one it turns 90 ° on to .

Explanation of how reflection across axis works?When a graph is reflected along an axis, say x axis, then that leads the graph to go just in opposite side of the axis as if we're seeing it in a mirror.
If study it more, you will find that its symmetric, thus each point is equidistant from the axis of reflection as that of the image of that point.
Thus, if we are reflecting a point (x,y) along x axis, then its x abscissa will stay same but y ordinates will negate. Thus (x,y) turns to (x, -y)
Similarly, if we are reflecting a point (x,y) along y axis, the resultant image of the point will be (-x,y)
The sides and angles should be the same as the un-reflected version, except everything is flipped, thus the corresponding parts are attached below.

Answer:
c = 74
d = 122
a = 58
b = 48
Step-by-step explanation:
C: a triangle always equals to 180, so 48 + 58 - 180 = 74
D: Angels next to each other on a line always equal to 180, so 180 - 58 = 122
A: Alternating interior angles of a parallel line equal to each other, so it would also be 58
B: A line is 180, so C + A - 180 = B, 74 + 58 - 180 = 48
Find the surface area of a basketball with a diameter of 10 in.

100π in²
400π in²
Answer:
100π in²
Step-by-step explanation:
i just took the test :)
The surface area of the ball is 100π square inches. The correct option is C.
How to calculate the surface area of a sphere?The formula for the surface area of a sphere is:
Surface Area = 4πr²
Where r is the radius of the sphere.
Since the basketball has a diameter of 10 in, the radius is half of that, which is 5 in.
Substituting the radius into the formula, we get:
Surface Area = 4π(5²)
Surface Area = 4π(25)
Surface Area = 100π
Therefore, the surface area of the basketball is 100π in².
So the surface area is 100π in².

Given the 3 points A(0;1) , B(5;0) , and C(4;2)
a) Find the coordinates of M the midpoint of [AB]
b) Find the coordinates of G the center of gravity of the triangle ABC .
Answer:
The answer is below
Step-by-step explanation:
a) If O(x, y) is the midpoint between two points X(x₁, y₁) and Y(x₂, y₂)m then the coordinates of O is:
x = (x₁ + x₂)/2; y = (y₁ + y₂) / 2
Since M(x, y) is the midpoint of AB, then the coordinates of M is:
x = (0 + 5) / 2 = 2.5; y = (1 + 0)/2 = 0.5
M = (2.5, 0.5)
b) The center of gravity is gotten by finding the average of the x coordinates and the y coordinates of the vertices of the triangle.
Let O(x, y) be the center of gravity of triangle ABC, hence;
x = (0 + 5 + 4) / 3 = 3
y = (1 + 0 + 2) / 3 = 1
O = (3, 1)
