The equation for line j can be written as y = 2x + 8. Another line k is perpendicular
to line j and passes through the point (6, -6). Choose the equation for line k.
Slope Intercept: y = mx + b
Point slope: (Y - Y1 ) = m (X - X1 )
A y =

2 – 3

y = - 2 - 3

B
y = -2x – 3
3
y=- 2 + 3
2
Answer:
Solution given:
equation of line j is:
y=2x+8
comparing above equation with y=mx+c
we get
m=2
let slope of another line k be M
since lines are perpendicular
their product is -1
so
m *M=-1
2M=-1
M=-½
since it passes from (6,-6)
we have
(y-y1)=M(x-x1)
(y+6)=-½(x-6)
2y+12=-x+6
x+2y+12-6=0
x+2y+6=0 is a required equation of line k.
Answer:
[tex] \displaystyle y = - \frac{1}{2} x - 3[/tex]
Step-by-step explanation:
we are given that,
[tex] \displaystyle E _{ j}: y = 2x + 8[/tex]
and it's perpendicular to [tex]E_k[/tex]
since [tex]E_k[/tex] is perpendicular to [tex]E_j[/tex] the slope of the equation of k has to be -½
because we know that
[tex] \displaystyle m_{ \text{perpendicular}} = - \frac{1}{m}[/tex]
we are also given a point where the perpendicular line passes as we got the slope and a point we can consider using point-slope form of linear equation to figure out the perpendicular line
remember the point slope form
[tex] \displaystyle y - y_{1} = m(x - x_{1})[/tex]
we got that, y1=-6,x1=6 and m=-½ thus,
substitute:
[tex] \displaystyle y - ( - 6)= - \frac{1}{2} (x - 6)[/tex]
remove parentheses:
[tex] \displaystyle y + 6= - \frac{1}{2} (x - 6)[/tex]
distribute:
[tex] \displaystyle y + 6= - \frac{1}{2} x + 3[/tex]
cancel 6 from both sides:
[tex] \displaystyle y = - \frac{1}{2} x - 3[/tex]
hence, the equation of line k is y=-½x-3

Step-by-step explanation:
The figure shows the graphs of the functions y = f(x) and y = g(x). The four indicated points all have integer coordinates. y = f(x) y = g(x) If g(x) = k f(x), what is the value of k? I am not sure how to do this. k = -3
Answer:
k = -3
Step-by-step explanation:
f(x) = -2x+1
g(x) = 6x - 3
=> g(x) = k.f(x)
6x - 3 = k(-2x+1)
k = (6x-3)/(-2x+1)
= 3(2x-1)/-1(2x-1)
k = 3/(-1) = -3
The value of k for the given function will be k = -3.
What is a function?In mathematics, a function is a relation between a set of inputs and a set of possible outputs with the property that each input is related to exactly one output. A function can be thought of as a machine that takes an input, performs a certain operation on it, and produces an output.
Formally, a function is defined as a set of ordered pairs (x, y) such that each value of x is associated with exactly one value of y. The set of all possible inputs to a function is called its domain, while the set of all possible outputs is called its range.
The given functions are,
f(x) = -2x+1
g(x) = 6x - 3
The value of k will be calculated as,
g(x) = k.f(x)
6x - 3 = k(-2x+1)
k = (6x-3)/(-2x+1)
k= 3(2x-1)/-1(2x-1)
k = 3/(-1) = -3

Kalo randomly surveyed 25 students at his school and found that 19 of them have at least one sibling. Based on these data, how many of the 125 students at his
school would be expected to have at least one sibling?
Answer:
95 students
Step-by-step explanation:
25 students -- 19 have sibling
1 student -- (19/25)
125 students -- (19/25) * 125 = 95
Therefore, 95 students out of 125 are expected to have at least one sibling.
Thenks and mark me brainliest :))
Answer:
95
Step-by-step explanation:
Calculate the experimental probability of choosing a student who has at least one sibling: It is 19/25, or 0.56.
If 125 students are selected, this probability applies. Multiply 125 by 0.56:
0.56(125 students) = 95
95 students could be expected to report having at least one sibling.

At a location 30m from the base of a flagpole, the angle of elevation is 34 degrees. Determine the height of the flagpole to the nearest meter.
Answer:
20.2 m
Step-by-step explanation:
At a location 30m from the base of a flagpole, the angle of elevation is 34 degrees. Determine the height of the flagpole to the nearest meter.
We solve this question using the Trigonometric function of Tangent
tan θ = Opposite/Adjacent
θ = 34°
Adjacent =30m
Opposite = Height of the flag pole = x
Hence
tan 34 = x/30
Cross Multiply
tan 34 × 30m
= 20.235255505 m
Approximately = 20.2 m
Hence, the height of the flag pole to the nearest meter = 20.2m

Find the 8th Term for the Geometric Sequence for which a1 - 3 and r = -2
Answer:
-384
Step-by-step explanation:
geometric sequence : every new element is generated by multiplying the previous element always with the same number r.
a(n) = a(n-1) * r
a(n) = a(1) * r^(n-1)
so, a(1) = 3, r = -2
a(8) = ?
a(8) = a(1) * r^7 = 3 * (-2)^7
a negative number to an uneven power is again a negative number.
so, (-2)^7 = -128
3 * -128 = -384 = a(8)

A rectangular tank measures 16 cm by 9 cm by 10 cm. How many milliliters of water are in the tank when it is full? How many liters?
Answer:
1,440 cubic centimeter = 1,440 milliliters
1,440 cubic centimeter= 1.44 liters
Step-by-step explanation:
Volume of the rectangular tank = length × width × height
Length = 16 cm
Width = 9 cm
Height = 10 cm
Volume of the rectangular tank = length × width × height
= 16 cm × 9 cm × 10 cm
= 1,440 cm³
Volume of the rectangular tank = 1,440 cm³
How many milliliters of water are in the tank when it is full?
1 cubic centimeter = 1 milliliter
1,440 cubic centimeter = 1,440 milliliters
How many liters?
1 cubic centimeter = 0.001 liters
1,440 cubic centimeter= 1.44 liters

Solve for b.
-3b+2.5 = 4
Answer:
b = −0.5
Step-by-step explanation:
Let's solve your equation step-by-step.
−3b+2.5=4
Step 1: Subtract 2.5 from both sides.
−3b+2.5−2.5=4−2.5
−3b=1.5
Step 2: Divide both sides by -3.
-3b/-3 = 1.5/-3
The value of 'b' in the equation given is -0.5
Given the expression for which we could solve for the unknown:
-3b + 2.5 = 4Subtract 2.5 from both sides
-3b = 4 - 2.5
-3b = 1.5
divide both sides by -3 to isolate b
-3b/-3 = 1.5/-3
b = -0.5
Therefore, the value of b in the equation given is -0.5
