write an equation for the line that passes through (4,10) and is perpendicular to the line 6x-3y=5
Answer:
[tex]y = - \frac{ 5}{3} x + ( - \frac{5}{3} )[/tex]
Step-by-step explanation:
-3y=5-6x
y=5-6x÷(-3)
y=(-5/3)+2x
y=2x-(5/3)
At y-intercept x is 0 and y is -(5/3)
Gradient m=10-(-5/3)÷(4-0)
=35/12
y=mx+c
10=(35/12)4+c
c=-(5/3)
Answer:
y = [tex]-\frac{1}{2}[/tex]x + 12
Step-by-step explanation:
Given expressions:
Coordinates = (4,10)
Equation of the line; 6x - 3y = 5
Unknown:
Equation of the line perpendicular = ?
Solution:
A line perpendicular to the given one will have a negative inverse slope.
Equation of any given line is expressed as:
y = mx + c
y and x are the coordinates
m is the slope
c is the intercept
Now; re-write 6x-3y = 5 in the form y= mx + c and find the slope;
6x - 3y = 5
-3y = 5- 6x
y = [tex]-\frac{5}{3}[/tex] + 2x
The slope of a perpendicular line will be [tex]-\frac{1}{2}[/tex]
Also, let us find the y-intercept, c;
y = mx + c
10 = [tex]-\frac{1}{2}[/tex] x 4 + c
10 = -2 + c
c = 12
The equation of the new line is ;
y = [tex]-\frac{1}{2}[/tex]x + 12
The sum of the number and three times its reciprocal is 79/10. Find the
number.
hi
so x + 3 (-x) = 79/10
x-3x = 79/10
-2x = 79/10
x = 79/10 / -2
X = 79/ 10 * -1/2
x = - 79/20
x = - 3.95

Answer:
The answer is C
Step-by-step explanation:
Answer:
C
Step-by-step explanation:
f(0) means the graph of f(x) in which the value of the variable x in the function f is zero.. So, f(0) represents graph for zero value of x

it cost 13.80 for 5 tickets how much would it cost for 3 tickets
Answer:
$8.28
Step-by-step explanation:
So, first we must find the price per ticket so we do
13.80/5 = 2.76
So the $2.76 per ticket
So now all we do to find the price of three tickets we times the price per ticket by 3
2.76 x 3 = $8.28
4x+c=w make x a subject
plz help me
answer me fast
and i want answer kn step by step
Answer:
x =w-c/4
Step-by-step explanation:
solution
here,
4x+c=w
or, 4x=w-c
:.x=w- c/x
As x subject, the linear equation is x = 1/4(w -c).
What is linear equation?Equations whose variables have a power of one are called linear equations. One example with one variable is where ax+b = 0, where a and b are real values and x is the variable.
We have a linear equation,
4x+c=w.
To make x a subject:
4x = w - c
x = 1/4(w -c)
Therefore, the expression is x = 1/4(w -c).

Let sets A and B be defined as follows.
A is the set of integers greater than - 7 and less than - 3
B={c, h, j, k, v, y}
(a) Find the cardinalities of A and B.
n(A) = ? n(B)= ?
(b) Select true or false.
True
False
-6E A
-14 EA
k E B
Q E B
The E is the signal used not the actual letter E
Answer:
n(A) = 3
n(B) = 6
-6 ∈ A => True
-14 ∈ A => False
k ∈ B=> True
Q∈B = >False
Step-by-step explanation:
Given
A is the set of integers greater than - 7 and less than - 3
B={c, h, j, k, v, y}
For set A:
The integers greater than -7 will be -6,-5 ....
As the set has integers less than -3, the set will be:
[tex]A = \{-6,-5,-4\}[/tex]
Cardinalities:
Cardinality is the number of elements in the set.
So,
[tex]n(A) = 3\\n(B) = 6[/tex]
Now for the statements:
-6 ∈ A True as -6 is a member of set A
-14 ∈ A False as -14 is not a member of A
k ∈ B True
Q∈B False
Hence,
n(A) = 3
n(B) = 6
-6 ∈ A => True
-14 ∈ A => False
k ∈ B=> True
Q∈B = >False

Two hot air balloons.
Balloon one: starts at 30 miles from town and after 2 hours, it is 48 miles
Distance of Tasha's balloon is represented by function y = 8x + 20
x is independent variable so it would represent the time.
y is dependent so it represents the miles travelled.
Balloon one = (0, 30) <-- begins here and (2, 48)
Balloon two = (0, 20).
So balloon one began at 30 miles while tasha's balloon began at 20 miles from town.
So Henry's balloon was farther form the town at the beginning.
Now let's find the slope/rate of change and compare then.
Henry's balloon: y-y1/x-x1 = 48-30/2 = 18/2 = 9
Tasha's balloon m: 8
9>8 Therefore henry was faster
Q.Find the selling price if the cost price is $1200 and loss percent is 25?
Write in step by step
Step-by-step explanation:
C.p=1200
loss percent=25
s.p=?
s.p=100- loss×C.p/100
s.p=100- 25×1200/100
S.p=75×1200/100
s.p=90000/100
s.p=900

it costs 13$ for admission to amusement park, plus 1.50$ for each ride.if you have a total of 35.50 to spend, what is the greatest number of rides you can go on
Answer:
Thus, the greatest number of rides I can go on is 15 rides
Step-by-step explanation:
I have $35.50 to spend for admission plus rides in the amusement park.
Admission costs $13. That leaves me with
$35.50 - $13 = $22.50
to spend on rides.
Considering each ride costs $1.50, we can find the maximum number of rides by dividing the remaining money by the cost per ride as follows:
$22.50 / $1.50 = 15
Thus, the greatest number of rides I can go on is 15 rides
