Answer: B
Step-by-step explanation:
The equation [tex]y+2=\frac{3}{4} x-8[/tex] is not yet in slope-intercept form([tex]y=mx+b[/tex]). Simply subtract 2 from both sides to turn the equation into slope intercept form as [tex]y=\frac{3}{4}x-10[/tex]. For a line to be perpendicular to another, it must have an opposite reciprocal slope. A reciprocal is the fraction reversed, where the numerator is the denominator and vice versa. Thus, 3/4 would become 4/3. The opposite reciprocal of 3/4 would be -4/3.
The slope of the line given is 3/4. Thus, simply plug in the opposite reciprocal of 3/4 for the slope to get: [tex]y=-\frac{4}{3} x+b[/tex]. Then, because the line passes through -12, 1, plug those values in for x and y, respectively.
[tex]1=-\frac{4}{3}*-12+b[/tex]
[tex]1=16+b[/tex]
[tex]-15=b[/tex]
Thus, the equation of the line is [tex]y=-\frac{4}{3} x-15[/tex], or B.

math question problem
I need help with this please help .
Answer:
Subs: 49.5 students, Tex-mex: 144 students, Italian: 31.5 students
Step-by-step explanation
The number of students eating a type of food can be found by using:
Percent * number of students
So in this equation, we can use this formula to find the answers.
Subs:
22% * 225 = 0.22 * 225 = 49.5
Tex-mex:
64% * 225 = 0.64 * 225 = 144
Italian:
14% * 225 = 0.14 * 225 = 31.5
There is an issue- you can't have half a person. Either this question is wrong, or the person who wrote it didn't keep this in mind.
Ask your teacher whether this question is right, or just leave the answer like this.
Is this a function? thanks for the answers:)
Answer:
Yes
Step-by-step explanation:
I am pretty sure it is a linear function
Answer:
yes
Step-by-step explanation:
[tex]3x+6-y=2y-8\\\\3x+6=2y+y-8\\\\3x+6=3y-8\\\\3y-8=3x+6\\\\3y=3x+6+8\\\\3y=3x+14\\\\y=x+\frac{14}{3}[/tex]
so yes it's a function
how do I solve the symptoms of linear equations by substitution
2x-y=23
x-9=-1
Answer:
x = 8, y = -7
in coordinate form: (8,-7)
Step-by-step explanation:
first, find x using the second equation:
x - 9 = -1
add 9 to both sides of the equation
x - 9 + 9 = - 1 + 9
x = -1 + 9
x = 8
next, substitute x for 8 in the first equation:
2x - y = 23
2 * 8 - y = 23
16 - y = 23
16 - y + y = 23 + y
16 = 23 + y
16 - 23 = y
y = -7
also, I had this exact question on an assignment earlier today ahah
Given the following, find the value of x.
(4x+45)
(5x-18)
Step-by-step explanation:
Hey ..but there is nothing from which question can be equated ..
like if they are equal to zero..
or
(4x+45)=(5x-18)
i am giving answer for both scenarios
(4x+45)=0
4x=-45
x=-45/4
x=(-11.25)
(5x-18)=0
5x=18
x=18/5
x=3.6
Incase if they both are equal to each other...
(4x+45)=(5x-18)
(45+18)=(5x-4x)
63=x
x=63
Hope it helps you
Have a nice day

You sell small and large candles at a craft fair. You collect $144 selling a total of 28 candles. How many of each type of candle did you sell? A photo shows a small candle labeled 4 dollars each and a large candle labeled 6 dollars each.
Answer:
The number of
Small candles = x = 12 candles
Large candles = y = 16 candles
Step-by-step explanation:
You sell small and large candles at a craft fair. You collect $144 selling a total of 28 candles. How many of each type of candle did you sell? A photo shows a small candle labeled 4 dollars each and a large candle labeled 6 dollars each.
Let the number of
Small candles = x
Large candles = y
Our system of equations is:
x + y = 28 .......... Equation 1
x = 28 - y
A photo shows a small candle labeled 4 dollars each and a large candle labeled 6 dollars each.
4x + 6y = 144......... Equation 2
Substitute 28 - y for x in Equation 2
4(28 - y) + 6y = 144
112 - 4y + 6y = 144
- 4y + 6y = 144 - 112
2y = 32
y = 32/2
y = 16 candles
x = 28 - y
x = 28 - 16
x = 12 candles
Therefore:
The number of
Small candles = x = 12 candles
Large candles = y = 16 candles

Find y.
Round to the nearest tenth:
31°
y
X
400 ft
y = [? ]ft
Answer:
y = 240.3 ft
Step-by-step explanation:
Use trigonometric ratio to find y:
Thus,
Reference angle = 90° - 31° = 59°
Opposite = 400 ft
Adjacent = y
Therefore:
Tan 59° = 400/y
Multiply both sides by y
y*tan 59 = 400
Divide both sides by tan 59
y = 400/tan 59
y = 240.3 ft (to the nearest tenth)
An observation tower's shadow is 32 feet long. Not far away, a marble column's shadow is 8 feet long. If the observation tower is 60 feet tall, how tall is the marble column?
Answer:
15 feet
Step-by-step explanation:
This is calculated using the formula
Height of observation tower/Shadow of observation tower = Height of Marble column/Shadow of marble column
From the question
Height of observation tower = 60 ft
Shadow of observation tower = 32 ft
Height of Marble column = ? x
Shadow of marble column = 8 ft
Hence:
60ft/32ft = x/8ft
Cross Multiply
60ft × 8 ft = 32ft × x
x = 60 ft × 8 ft/32 ft
x = 15 ft
Therefore, the marble column is 15 feet tall

Solve the algebraic equation -4x +2 (x - 1)^2
Answer:
2x^2 - 8x + 2
Step-by-step explanation:
-4x + 2(x-1)^2
= -4x + 2(x^2 -2x +1)
= -4x + 2x^2 - 4x + 2
= -8x + 2x^2 + 2
=2x^2 - 8x + 2 (usually put the exponent kind of things first)

Cos 60° = 0.5
b) What is the value of x?
(2)
Answer:
Hypotenuse = 10 Cm
Step-by-step explanation:
Given:
θ = 60°
Base = 5 cm
Hypotenuse = x cm
Find:
Hypotenuse
Computation:
Cos θ = Base / Hypotenuse
Cos 60° = 5 / Hypotenuse
0.5 = 5 / Hypotenuse
Hypotenuse = 10 Cm

A company that makes hair-care products had 4,000 people try a new shampoo. Of 4,000 people, 24 had a mild allergic reaction. What percent of the people had a mild allergic reaction?
Please help me!!!
the answer is 0.6% i think hope this helps
Answer:
0.6%
Step-by-step explanation:
[tex]\frac{24}{4000}[/tex] = 0.6%
To get the solution, we are looking for, we need to point out what we know.
1. We assume, that the number 4000 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 100% equals 4000, so we can write it down as 100%=4000.
4. We know, that x% equals 24 of the output value, so we can write it down as x%=24.
5. Now we have two simple equations:
1) 100%=4000
2) x%=24
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
100%/x%=4000/24
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for 24 is what percent of 4000
100%/x%=4000/24
(100/x)*x=(4000/24)*x - we multiply both sides of the equation by x
100=166.666666667*x - we divide both sides of the equation by (166.666666667) to get x
100/166.666666667=x
0.6=x
x=0.6
now we have:
24 is 0.6% of 4000

4. At Sports Shoe Warehouse, the cost of 9 pairs of baseball shoes is $855 plus $92 for each additional pair.
From Winning Team Shoes, the cost of 9 pairs of baseball shoes is $810 plus an additional 7% for each
additional pair. For how many total pairs of baseball shoes does each vendor cost about the same?
Answer:
10.46
Step-by-step explanation:
Let the Number of additional pair = x
Ware house A :
855 + 92x - - - (1)
Warehouse B:
Initial cost per pair before 9
= 810 / 9 = $90
Additional 7% for pairs after 9
1.07 * 90 = 96.3
810 + 96.3x - - - (2)
810 + 96.3x = 855+ 92x
96.3x - 92x = 855 - 810
4.3x = 45
x = 45 / 4.3
x = 10.46
Additional pair be 10.46

31. Two charged particles, each of 2 x 10-C, are brought from infinity to a
separation of 5 cm. Find the increase in electrical potential energy in the
process.
Answer:
P = 72 J
Step-by-step explanation:
Given that,
Charges, [tex]q_1=q_2=2\times 10^{-5}\ C[/tex]
These charges are brought from infinity to a separation of 5 cm.
We need to find the increase in the electrical potential energy in the process. The formula for the electric potential energy is given by :
[tex]P=k\dfrac{q_1q_2}{r}\\\\P=9\times 10^9\times \dfrac{(2\times 10^{-5})^2}{0.05}\\\\P=72\ J[/tex]
So, the required electric potential energy is 72 J.
