Step-by-step explanation:
The slope of the line [tex]y = 2x - 3[/tex] is 2, which means that a line perpendicular to this will have a slope equal to its negative reciprocal or [tex]m = -\frac{1}{2}.[/tex] So we can write the slope-intercept form of the line's equation as
[tex]y = -\frac{1}{2}x + b[/tex]
To find the value of b, we use the value of the given point (-3, 3):
[tex]\Rightarrow 3 = -\frac{1}{2}(-3) + b[/tex]
Solving for b, we get
[tex]b = \frac{3}{2}[/tex]
Therefore, the slope-intercept form of the equation for the perpendicular line is
[tex]y = -\frac{1}{2}x + \frac{3}{2}[/tex]

You can multiply by √5/√5 as you have done, and as conventionally taught, or you can multiply by 5/5 under the radical to make the denominator a perfect square.

Write an equation to determine the weight, www, of each of Carl's checked bags.Find the weight of each of his checked bags.
Answer:
[tex]w=15.5[/tex]
[tex]w=\frac{31}{2}[/tex]
Equation:
[tex]2w+4=35[/tex]
Step-by-step explanation:
[tex]2w+4=35\\2w=31\\w=15.5[/tex]
Hidden Steps:
1) Subtract 4 on each side of the equation:
[tex]2w+4-4=21\\35-4=31[/tex]
2) Divide each side of the equation by 2:
[tex]2w[/tex] ÷ [tex]2=w[/tex]
[tex]31[/tex] ÷ [tex]2=15.5-or-\frac{31}{2}[/tex]
Answer:
Equation: 2w + 4 = 35
Weight: 15.5
Step-by-step explanation:
Let w be the weight of each checked bag.
The weight of Carl's 2 checked bags is 2w kg. The weight of his backpack is 4kg. The total weight of his baggage is 2w + 4 kg.
Since his total baggage weighs 35 kg, let us set this to 35:
2w + 4 = 35
Now you solve:
1. 2w + 4 = 35
2. 2w = 35-4
3. 2w = 31
4. w = 31/2
5. w = 15.5
Therefore, the equation is 2w + 4 = 35 and the solution to " w " is 15.5 kg.

IN A CLASS OF 60 STUDENTS, 25 PLAYS BASKETBALL, 2O PLAY VOLLEYBALL, AND 10 STUDENTS PLAY BOTH OF THEM. HOW MANY STUDENTS PLAY NEITHER BASKETBALL NOR VOLLEYBALL ?
Answer:
5
Step-by-step explanation:
60-25=35
35-20=15
15-10=5
5 people dont play either of them
Answer:
25
Step-by-step explanation:
To solve this, we can add the number of basketball players and the number of volleyball players:
25 + 20 = 45
But we know that there are ten players who are counted twice because they play both. So we subtract 10:
45 - 10 = 35
And that is the total number of students who play either basketball or volleyball. Now to figure out those that play neither sport we subtract the number of students by the number of players:
60 - 35 = 25
That’s the number of students who don’t play one of those sports.
To amend the U.S. Constitution, 3/4 of the 50 states must approve the amendment. If 35 states approve the amendment will the constitution be amended
bearing in mind that fraction wise we can represent any WHOLE as 1, 5/5 = 1, or 333/333 = 1, so we can say that the whole of the states or namely 50/50 = 1, so we can say that
[tex]\begin{array}{ccll}amount&fraction\\\cline{1-2}50&1\\35&x\end{array}\implies \cfrac{50}{35}=\cfrac{1}{x}\implies 50x=30\implies x=\cfrac{30}{50}\\\\\\\boxed{x = \cfrac{3}{5}\implies 0.7}\\\\[-0.35em]~\dotfill\\\\\cfrac{3}{4}\implies 0.75~\hspace{10em}\stackrel{\textit{since 0.7 is less than 0.75, \underline{nope}}}{0.7 < 0.75}[/tex]

What is quadratic equation?A quadratic equation is an algebraic equation of the second degree in x. The quadratic equation in its standard form is ax² + bx + c = 0, where a and b are the coefficients, x is the variable, and c is the constant term.
Given:
f(x) = ax² + bx + c
The first condition for an equation to be a quadratic equation is the coefficient of x² is a non-zero term(a ≠ 0).
For writing a quadratic equation in standard form, the x² term is written first, followed by the x term, and finally, the constant term is written.
Hence, The constants a, b, and c must be real numbers with a not ever equal to zero.

Solve for SR.
Also feel free to tell us how your day has been :D
Answer:
12
Step-by-step explanation:
Triangle PQR and triangle STR are congruent and that makes |PR| and |SR| equal in measure:
2x + 6 = 4x export like terms to same side
6 = 4x - 2x subtract
6 = 2x divide both sides by 2
3 = x
SR is represented with 4x now replace x with 3
SR = 4*3 = 12

Y=
Answer:
y≈94.31
Step-by-step explanation:
Hi there!
We're given a right triangle (notice the 90 degree angle), the measure of one of the legs (one of the sides that make up the right angle) as 46, the other one as y, and one of the angles as 26°
We want to solve for y
We can use a trigonometric ratio to do that.
First, let's recall the three most-well known ratios:
Sine is [tex]\frac{opposite}{hypotenuse}[/tex]
Cosine is [tex]\frac{adjacent}{hypotenuse}[/tex]
Tangent is [tex]\frac{opposite}{adjacent}[/tex]
Since we are given one of the angles, let's find out which sides are the opposite, adjacent, and hypotenuse, in reference to the given angle (the 26° angle)
In reference to that angle, the side opposite to that angle (also the side known as "opposite) is the side marked as 46, the adjacent side is y, and the hypotenuse is the unmarked side
Since we know the opposite and adjacent, let's use the ratio for tangent
Since we based our labels off of the 26 degree angle, the tangent ratio is the tangent OF 26, or tan(26)
tan(26)=[tex]\frac{46}{y}[/tex]
Now we need to solve the equation
Start by multiplying both sides by y
tan(26)*y=46
Divide both sides by tan(26)
y=[tex]\frac{46}{tan(26)}[/tex]
Plug [tex]\frac{46}{tan(26)}[/tex] into your calculator, and remember to have the calculator on degree mode
[tex]\frac{46}{tan(26)}[/tex]≈94.31
Remember that [tex]\frac{46}{tan(26)}[/tex] is equal to y, which means that y is about 94.31
Hope this helps!

The youth group is going on a trip to the state fair. The trip costs $62. Included in that price is $14 for a concert ticket and the cost of 2 passes, one for the rides and one for the game booths. Each of the passes costs the same price. Write an equation representing the cost of the trip, and determine the price of one pass. Solve your equation by showing your work and steps.
Answer:
11+2x= 52 , $20.50 equal one pass
Step-by-step explanation:52 is the total and $11 is included in that total. So you have part of your equation : 11 + something = 52. In order to find that " something " you have to set up a variable : 2x , 2 because that is the amount of passes bought and X because you don't know the cost of the passes yet. You now have your equation : 11+2x=52. Next you isolate the "2x" by subtracting eleven from itself and what you do to one side of the equation you have to do to the other, so you subtract 11 from 52 and are left with 41 . You then have the simplified equation : 2x=41 . Now you're going to isolate the variable by dividing 2x by 2 and doing the same to 41. You're then left with X= 20.50 , the cost of one ticket
