Passes through (- 1, - 8) and perpendicular to x + 3y = - 6
What is the equation?
Answer:
y = 3x - 5
Step-by-step explanation:
1) First, place the given equation in slope-intercept form, represented by the formula [tex]y = mx +b[/tex], to find the slope. Whatever [tex]m[/tex] or the coefficient of x-term is will be the slope. Isolate y in the equation:
[tex]x + 3y = -6\\3y = -x -6\\y = -\frac{1}{3}x-2[/tex]
So, the slope of that line is [tex]-\frac{1}{3}[/tex]. Lines that are perpendicular have slopes that are opposite reciprocals, thus the slope of the new line will be 3.
2) Now, use the point-slope formula [tex]y-y_1 = m (x-x_1)[/tex] to find the equation of the new line. Substitute real values for the [tex]m[/tex], [tex]x_1[/tex] and [tex]y_1[/tex] in the equation.
Since [tex]m[/tex] represents the slope, substitute [tex]-\frac{1}{3}[/tex] in its place. Since [tex]x_1[/tex] and [tex]y_1[/tex] represents the x and y values of one point the line passes through, substitute the x and y values of (-1,-8) into the formula as well. Then, isolate the y in the resulting equation to put the equation in slope-intercept form and find an answer:
[tex]y-(-8) = 3 (x-(-1))\\y + 8 = 3(x+1)\\y + 8=3x + 3\\y = 3x -5[/tex]

Of the 34 students in a class there are 2 fewer students with blue eyes than there are with hazel eyes. also there are twice as many students with brown eyes. which of these is either the number of students with blue eyes the number of students with brown eyes or the number of students with hazel eyes. select all that apply.
A. 8
B. 10
C. 12
D. 16
E. 20
F. 34
Answer:
D
Step-by-step explanation:
bl is blue eyes h = hazel eyes br = brown eyes
eq 1) bl + h + br = 34 sum of all the students
eq 2) bl + 2 = h blue eyes plus 2 equal hazel eyes
eq 3) br = 2( bl + h ) there are twice as many brown eyed student
as blue eyed and hazel eyed students
eq 1) bl + h + br = 34 substitute for h in eq 2) bl + 2 = h
bl + (bl + 2) + br = 34
eq 4) 2bl + 2 + br = 34 a new equation is created without h
eq 3) br = 2(bl + h) substitute in for h into eq 3) using eq 2)
br = 2bl + 2h remember eq 2 was be + 2 = h
br = 2bl + 2(bl + 2)
eq 5) br = 4bl + 4 another eq WITHOUT h
now solve eq 4) and eq 5) by subsitition
eq 5) br = 4bl + 4 sub bl into eq 4)
eq 4) 2bl + 2 + br = 34
2bl + 2 + (4bl + 4) = 34 ONE equation with ONE unknown
solve for bl
2bl + 4bl + 2 + 4 = 34
6bl + 6 = 34
6bl + 6 - 6 = 34 - 6
6bl = 28
3bl = 14
bl = 14/3 = 4 2/3 so who has the 2/3 eye???
none of these numbers match the solution options
need to check my answer for sure my math was correct
bl + h + br = 34 bl = 14/3
eq 2) bl + 2 = h 14/3 + 6/3 = h h = 20/3
eq 3) br = 2( bl + h )
br = 2(14/3 + 20/3)
br = 2(34/3)
br = 68/3
bl + h + br = 34
14/3 + 20/3 + 68/3 = 102/3 102/3 = 34 the numbers check
************ i suspect the equation was typed incorrectly ****************
if the total number of students were 36
blue eyes = 5
hazel eyes = 7
brown eyes = 2 times (5 +7) = 24
5 + 7 + 24 = 36
again none of these numbers match option
if the total number of students were 24
blue eyes = 3
hazel eyes = 5
brown eyes = 2 times (5 +7) = 16 D = 16
3 + 5 + 16 = 24
hi i need some help on this, please explain
Answer:
w = 32
Step-by-step explanation:
Remark
The value of the exterior angle (marked w + 33) = the sum of the two angles not connected to it. w and w + 1
Equation
w + w + 1 = w + 33
Solution
2w + 1 = w + 33 Subtract w from both sides.
2w - w + 1 = 33 Combine
w + 1 = 33 Subtract 1 from both sides.
w = 33 - 1
w= 32
tap A fills a tank in 6 hours tap B fills it in 8 hours and tap C empties it in 10 hours. starting with an empty tank and all the three taps are opened find how long it takes to fill the tank?
Answer:
It will take 5 hours and 5 minutes to fill the tank
Step-by-step explanation:
Here, we want to get how long it takes to fill the tank
Let us have the capacity of the tank as 120 l
For the first tank, the number of liters filled per hour is 120/6 = 20 l
For the second, the number of liters filled per hour is 120/8 = 15 l
For the draining tap, the amount drained in an hour is 120/10 = 12 l
So total input is (15 + 20) = 35 l
Output is 12 l
Hourly retention is 35-12 = 23 l
To complete total 120 l, time taken will be;
120/23 = 5 5/23
So what this mean is that it will take 5 hours and 5 minutes

A rock is dropped down from the top of a 500-foot cliff. After 1 second, the rock is traveling 32 feet per second. After 5 seconds, the rock is traveling 160 feet per second.
a. Assume that the relationship between time, t, and speed, s, is linear, and write an equation describing this relationship. Use ordered pairs of the form (time, speed).
b. Use this equation to determine the speed of the rock 7 seconds after it is dropped.
Answer:
A) s=32t
B) 224 ft/s
Step-by-step explanation:
A)
In the form (time, speed), the question gives us the following data: (1,32) and (5,160). Since we are told that the relationship between time, t, and speed, s, is linear, we know the equation will fit the formula y=mx+c, where m is slope c is the y-intercept and y and x are the co-ordinate values. Plug in (1,32) and (5,160) to find the formula:
y=mx+c
s=mt+c
32=1m+c
c=32-m
160=5m+C
160=5m+32-m
128=4m
m=32
c=32-m
=32-32=0
So our equation is s=32t
B)
s=32t
s=32(7)=224 ft/s

Answer:
∠AOB = 112°
Step-by-step explanation:
mentally draw line segment OC
that line bisects 124° so ∠OCB = 1/2(124°) = 62°
ΔOCB is isosceles because OB = OC
∠OBC = 62° because it is equal to ∠OCB
all triangle interior angles add up to 180°
∠BOC = 180° - 62° - 62° = 56°
∠AOC = 56° because OC was a bisector of ∠AOB
∠AOB = 56° + 56° = 112°
Yong is measuring two pyramids whose bases are rectangles.
Given the length and width of the base of the first pyramid, as well as its volume V, Yong uses the formula

Answer:
angle C = 69 degrees
Step-by-step explanation:
(6x - 9) + (6x - 24) + (81 - x) = 180
11x + 48 = 180
11x = 132
x = 12
(81 - 12) = 69 degrees
Answer:
69°
Step-by-step explanation:
All angles in a triangle must add to 180°:
(5x+9)+(4x+15)+(x+36)=180
10x+60=180
10x=120
x=12°
The problem asks for the measure of angle C:
C=(81-x)°=69°
You were on the right track because you got the value of x correct. You just didn't answer the problem correctly.

Imagine you are starting an office supply business. Your overall costs for supplies are $100. You plan on selling binders for $4 each and pencils for $2 each. Let x represent the number of binders sold and y represent the number of pencils sold.
Complete question :
Imagine you are starting an office supply business. Your overall costs for supplies are $100. You plan on selling binders for $4 each and pencils for $2 each. Let x represent the number of binders sold and y represent the number of pencils sold. Give an expression for the profit made.
Answer:
(2y + 4x) - $100
Step-by-step explanation:
Given that:
Cost of supply = $100
Supplies :
binders, sales price = $4
Pencils, sales price = $2
Number of binders sold = x
Number of pencils sold = y
The revenue from sale :
(Cost of pencils * number of pencils) + (cost of binders * number of binders)
Revenue = 2y + 4x
Profit, p = Revenue - Cost of supply
p = (2y + 4x) - $100

Answer:
Step-by-step explanation:
I can only tell you that 4x-y=6 is parallel to y=4x-6. Do u mind sort out the rest of the variables and the numbers on your own?
The lines parallel to given line are y + 1 = 4(x - 2) and y = 4x + 11. Therefore, option C and D are the correct answers.
What is the equation of a line?The general equation of a straight line is y=mx+c, where m is the gradient, and y = c is the value where the line cuts the y-axis. This number c is called the intercept on the y-axis.
Given that, the equation of a line is 4x-y=6.
Now, y=4x-6
Here, the slope of the equation is 4.
The slope of a line parallel to given line is m1=m2
So, here the slope of a parallel line is 4.
y + 1 = 4(x - 2) and y = 4x + 11 have same slope, then they are parallel to given line.
Therefore, option C and D are the correct answers.
