Answer:
x + 2y - 3 = 0
Step-by-step explanation:
Coordinates of the points P and Q are (-3, 0) and (0, 6) respectively.
Slope of PQ = (0- 6)/(-3 - 0) = - 6/-3 = 2
Slope of line perpendicular to PQ = - 1/2
Since, required line passes through point R(7, - 2) and is perpendicular to PQ.
Therefore, equation of line in point slope form is given as:
[tex]y - (-2) = - \frac{1}{2} (x - 7) \\ \\ y + 2 = - \frac{1}{2} (x - 7) \\ \\2(y + 2) = - (x - 7) \\ \\ 2y + 4 = - x + 7 \\ \\ 2y + 4 + x - 7 = 0 \\ \\ x + 2y - 3 = 0[/tex]
Therefore x + 2y - 3 = 0 is the required equation of line.

The school production of 'Our Town' was a big success. For opening night, 391 tickets were sold. Students paid $4.00 each, while non-students paid $6.00 each. If a total of $1786 was collected, how many students and how many non-students attended?
Answers
Answer:
280 students
111 non students
Step-by-step explanation:
number of students (S)
number of non students (N)
S+N=391 S=391-N
4S+6N=1786
substitute S
4(391-N)+6N=1786
1564-4N+6N=1786
subtract 1564 from each side
2N=222
N=111
S=391-111=280

Part A: Bill earned $12 walking his neighbors' dogs on Saturday. He earned some extra money on Sunday doing the same thing. Write an expression with a variable that shows the total amount of money Bill earned Saturday and Sunday.
Part B: Bill was able to walk 2 more than twice as many dogs as his friend Steve. Write an algebraic expression to represent the number of dogs Bill walked compared with Steve.
Answers
Answer:
Part A: 12 + x
Part B: 2s + 2
Step-by-step explanation:
First thing you need to know is the difference between an expression and an equation. An expression does not have an equal sign, while an equation does.
To write an expression for Part A, first write the 12 (the amount he got on Saturday). Then, we need to write the addition sign (to find the total amount Bill earned). We don't know how much Bill earned on Sunday, so use any variable (I used x). Because we're writing an expression, do not write an equal sign.
To write an expression for Part B, first write the amount of dogs his friend Steve walked using a variable because we don't know that number (I used the variable s). Then, since Bill walked 2 more than twice as many dogs Steve walked, write the s multiplied by the 2 or just 2s. Now add the addition sign (to find the total amount Bill walked). Add a 2 because Bill walked 2 more dogs than twice as many Steve walked.
Hope it helps!
The expressions formed are 12+x and 2y+2.
What is an Expression?An expression is a mathematical statement which consists of variables, constants and mathematical operators.
Let x be the amount of money Bill earned on Sunday.
He earned $12 on Saturday.
The total amount of money Bill earned is,
=> 12 + x
Let the number of dogs Bill's friend Steve walked is y.
Then the expression for the number of dogs Bill walked compared with Steve is,
=> 2y +2

Step-by-step explanation:
s=number of sundaes sold
b=number of banana splits sold
2s+3b=154
s=2b
to solve:
substitute s=2b into the first equation
2(2b)+3b=154
4b+3b=154
7b=154
divide both sides by 7
7b/7=154/7

96 + x Less-than-or-equal-to 149
96 + x Greater-than-or-equal-to 149
96 + x > 149
96 + x < 149
Answers
This is the same as saying "96 + x less than or equal to 149"
====================================================
Explanation:
We start with 96 people already on board. We add on x more people. The x is a placeholder for a positive whole number.
In total, we have 96+x people on the plane. This total must not exceed the max capacity of 149. In other words, the largest value of 96+x is 149.
Since 96+x can be 149 or smaller, we can say 96+x ≤ 149

365.76 centimeters is the answer.
Hope this helps!
Plz, mark brainliest!
Answer:
365.76 cm in 12 feet
Step-by-step explanation:
Start by setting up two fractions which are equal to one another. We will use x as the unknown amount, which is the number of centimeters in 12 feet here.(see attached picture for a visual)
Now we can cross multiply, which gives us 12*60.96=2*x
Now, solving for x we divide 12*60.96=731.52 by 2, which gives us x=365.76 centimeters in 12 feet.

x = 1
x = 8
Step-by-step explanation:
to find y-intercepts, set x = 0
to find x-intercepts, set y = 0
1.) 4(0) + 5y = 20
5y = 20
y = 4 -------> y-intercept
2.) 4x + 5(0) = 20
4x = 20
x = 5 -------> x-intercept
3.) 2(0) + y = 2
y = 2 -------> y-intercept
4.) 2x + 0 = 2
x = 1 -------> x-intercept
5.) x - 2(0) = 8
x = 8 -------> x-intercept

4x+5y=20 the answer is below
x= −5/4y+5
y= −4/5x+4
2x+y=2 the answer is below
x= −1/2y+1
y=−2x+2
x-2y=8 the answer is below
x=2y+8
y=1/2x−4
Step-by-step explanation:
Let's solve for x.
4x+5y=20
Step 1: Add -5y to both sides.
4x+5y+−5y=20+−5y
4x=−5y+20
Step 2: Divide both sides by 4.
4x/4 = −5y+20/4
x= −5/4y+5
Answer:
x= −5/4y+5
Let's solve for y.
4x+5y=20
Step 1: Add -4x to both sides.
4x+5y+−4x=20+−4x
5y=−4x+20
Step 2: Divide both sides by 5.
5y/5 = −4x+20/5
y= −4/5x+4
Answer:
y= −4/5x+4
Let's solve for x.
2x+y=2
Step 1: Add -y to both sides.
2x+y+−y=2+−y
2x=−y+2
Step 2: Divide both sides by 2.
2x/2= −y+2/2
x= −1/2y+1
Answer:
x= −1/2y+1
Let's solve for y.
2x+y=2
Step 1: Add -2x to both sides.
2x+y+ −2x=2+ −2x
y=−2x+2
Answer:
y=−2x+2
Let's solve for x.
x−2y=8
Step 1: Add 2y to both sides.
x−2y+2y=8+2y
x=2y+8
Answer:
x=2y+8
Let's solve for y.
x−2y=8
Step 1: Add -x to both sides.
x−2y+−x=8+−x
−2y=−x+8
Step 2: Divide both sides by -2.
−2y −2=−x+8−2
y=1/2x−4

y=1/2x−4
