Given Eq:
√x + 3 = x - 3Solving this:
Squaring both sides,
➝ x + 3 = (x - 3)²
➝ x + 3 = x² - 6x + 9
Now shifting RHS to LHS,
➝ x + 3 - x² + 6x - 9 = 0
➝ -x² + 7x - 6 = 0
➝ x² - 7x + 6 = 0
Now finding the values of x by middle term factorisation,
➝ x² - 6x - x + 6 = 0
➝ x(x - 6) - 1(x - 6) = 0
➝ (x - 1)(x - 6) = 0
➝ x = 1 or 6.
But here, you can see, x = 1 is not a solution to the original equation because when we say about square roots, value can't be negative.
Hence,
As a result, the only valid solution to the original equation is x = 6.⛱️ [tex] \large{ \blue{ \bf{FadedElla}}}[/tex]

The school in town is building a track around its football stadium. The principal must decide whether to build a track with 6 lanes or 7 lanes. A 6-lane track will be 28.68 feet wide, and a 7-lane track will be 28.98 feet wide. If all lanes are of equal width in each track, how much wider will the lanes be in a 6-lane track than in a 7-lane track?
Answer:
the 6 lane track will be 0.64 feet wider than the 7 lane track
Step-by-step explanation:
28.68÷6=4.78
28.98÷7=4.14
4.78-4.14=0.64

Answer:
y = 1
Step-by-step explanation:
Recognize that 25 and 125 are powers of 5 and rewrite the equation in terms of powers of 5.
The applicable rules of exponents are ...
(a^b)^c = a^(bc)
(a^b)/(a^c) = a^(b-c)
(a^b)(a^c) = a^(b+c)
__
Your equation can be written as ...
[tex]25^4\div5^{5y}=125^y\\\\(5^2)^4\div5^{5y}=(5^3)^y\\\\5^{8-5y}=5^{3y}\\\\8-5y=3y\qquad\text{equate exponents of the same base}[/tex]
Now this can be solved as an ordinary linear equation.
8 = 8y . . . . . . add 5y to both sides
1 = y . . . . . . . divide by 8
The solution is y = 1.
1 + 6x - x = -9

Lucas is making a wire sculpture for art class. For the sculpture, he needs to cut a wire into pleces that
are each 1/16 of a foot long. If the original wire is 3/4 of a foot long, how many pieces will Lucas have?
⟹Answer:
➧Lucas can cut the wire into 12 pieces.
Step-by-step explanation:
⟹Lets Solve!
⟹The first step is to convert [tex]\frac{3}{4}[/tex] into [tex]\frac{}{16}[/tex] !
To do this we must find what number multiplied by 4 equals 16.
16 ÷ 4 = 4
⟹Now we know our multiplier is 4. So lets multiply the numerator and denominator by 4.
[tex]\frac{3}{4} * \frac{4}{4} = \frac{12}{16}[/tex]
[tex]\frac{12}{16}[/tex]
⟹Next we just divide [tex]\frac{12}{16}[/tex] by [tex]\frac{1}{16}[/tex].
[tex]\frac{12}{16}[/tex] ÷ [tex]\frac{1}{16}[/tex] = 12
➧Lucas can cut the wire into 12 pieces.
Woohoo! Brainliest appreciated! Hope I helped!
Based on the original length of the wire and the length Lucas requires, he will have 12 pieces.
The wire is 3/4 feet long and each piece required will be 1/16 feet.
The number of pieces in total is:
= Length of wire / Length of pieces
Solving gives:
= 3/4 ÷ 1/16
= 3/4 × 16/1
= 48/4
= 12 pieces
In conclusion, Lucas will have 12 pieces.

A group of friends equally split the dinner bill shown. If each person paid $16, how many friends paid?
Answer:
4
Step-by-step explanation:
Wait... this doesn’t make sense because it doesn’t tell you if there was tax, how many friends there were, or tips.
Answer:
16/y = x
Step-by-step explanation:
You cannot solve for the question yet. However, you can create an equation!
we know that each person paid 16 dollars.
We don’t know how much the bill was or how many people were there.
So out equation looks like;
z/y = x
or
z * x = y
z = how much each person paid.
y = how much each person paid.
x = how many people paid.
Substitute with what we know.
16/y = x
16 * x = y
Now you will be able to substitute for either x or y to find either answer.
Angel got paid $332.50. He had to pay income tax of 30%. How much money did he have left?
Answer:
$232.75
Step-by-step explanation:
Because the tax takes 30% of his pay, he will be left with 70%.
Multiply his pay by 0.7 to get the answer:
332.50 * 0.7 = 232.75

Density is also the slope of the relationship between mass and volume. If the density 7.2 g /mL, what is the slope?
Answer:
The slope for the substance = 7.2 g/mL
Step-by-step explanation:
Given that the density is also the slope relationship between mass and volume and that the density is equal to 7.2 g/mL, therefore, the slope of the equation of the line relating mass to volume is also equal to 7.2 g/mL
The density = Mass/Volume = 7.2 g/mL
The slope of mass volume relationship = (The change in mass)/(The equal change in volume)
Whereby the change is from the zero state, we have;
The slope of mass volume relationship = (Mass - 0))/(Volume - 0) = Mass/Volume
Therefore;
The value of the slope of the substance = The value of the density of the substance = 7.2 g/mL
The value of the slope for the substance = 7.2 g/mL.

Write the equation of the parabola in vertex form.
vertex (3,4), point (2,-2)
Answer:
y = - 6(x - 3)² + 4Step-by-step explanation:
The vertex form of the equation of the parabola with vertex (h, k) is:
y = a(x - h)² + k
So the equation of the parabola with vertex (3, 4):
y = a(x - 3)² + 4
The parabola passes through point (2, -2) so if x=2 then y=-2
- 2 = a(2 - 3)² + 4
- 2 -4 = a(-1)² + 4 -4
- 6 = a
So, the equation written in vertex form of a parabola with a vertex of (5, 7) that passes through (2, -2):
y = - 6(x - 3)² + 4

find the area of the trapezoid below by decomposing it into familiar shapes
Answer:
The area would be 168ft. The rectangle's area would be 144ft, and the triangle's area would be 24ft.
Rectangle:
18×8=144
Triangle:
8×3=24
Answer:
The area is 168
Step-by-step explanation:
Instead of trying to find the area of the trapezoid, you can easily figure out the area of the rectangle and triangle present in the picture.
first, multiply 18 by 8 to get the area of the rectangle. 18 x 8 = 144
Then, use the equation for area of triangle L x W/ 2 = A
(6 x 8)/2 = 24
add these 2 values.
24 + 144
168 is your final answer
There are 30 boys in a sporting club. 20 of them play hockey and 15 play volleyball. Each boys plays at least one of the two games. Illustrate the information on a Venn diagram. How many boys play all the two games. How many boys play only one game
Answer:
5 boys play all the two games
25 boys play only one game
Step-by-step explanation:
Sets
There are two sets defined in the question: one for the boys who play hockey (H) and the other for the boys who play volleyball (V).
All the boys play at least one of the two games, so no elements are outside both sets.
There are 30 boys in total. 20 of them play hockey and 15 play volleyball. Since the sum of both numbers is greater than the total of boys, the difference corresponds to the boys who play both games.
Thus 20 + 15 - 30 = 5 boys play both games
Given that 5 boys are shared by both sets, from the 20 playing hockey, 15 play ONLY hockey. From the 15 boys playing volleyball, 10 play ONLY volleyball.
Thus 15 + 10 = 25 boys play only one game.
The Venn diagram is shown in the image.

Answer:
I have the same questions and I got them right
Step-by-step explanation:
16. What is P(red, yellow, blue)?
P(red, yellow, blue)= 6/16= 3/8.
4/16+ 1/16+ 1/16= 6/16= 3/8
17. What is P(orange, yellow)?
P(orange, yellow)= 1/8
1/16+1/16= 2/16= 1/8
18. P(green, blue, purple)?
P(green, blue, purple)= 5/8
7/16+1/16+2/16= 10/16= 5/8.
19. P(pink)?
P(pink)=0
There is no pink color.
20. P(red, orange, yellow, green, blue, purple)?
P(red, orange, yellow, green, blue, purple)= 16/16= 1.
4/16+ 1/16+ 1/16+ 7/16+1/16+2/16 =16/16= 1.
What is the equation, in slope-intercept form, for the line that passes through the point (2, −3) and is perpendicular to the line represented by y = 25x + 4 ?
Answer:
The equation is;
y = (-x-23)/25
Step-by-step explanation:
The equation of a straight line can be given as y = mx + b
where m is the slope and b is the y-intercept
for y = 25x + 4
m is 25
Now, we need the slope of a line perpendicular to this,
If two lines are perpendicular, the result of the product of their slopes is -1
m1 * m2 = -1
25 * m2 = -1
m2 = -1/25
Mathematically, we have the slope in the point slope form as ;
y+3 = -1/25 (x - 2)
y = -x/25 + 2/25
y = -x/25 + 2/25 - 3
y = -x/25 -73/25

A regular polygon first maps directly onto itself after rotating 10 degrees. How many sides does the polygon have?
Answer:
I think it is 8.
Step-by-step explanation:
But I might be wrong.
Answer:
36 sides
Step-by-step explanation:
360 degrees divided by the number of sides equals the rotation degrees. So in order to have your polygon map itself after rotating 10 degrees, it would have to have 36 sides. 360/36 = 10.
