Answer:
b= (3z-6)/(1+3z)
Step-by-step explanation:
z=(-b+6)/(3b-3)
cross multiple
z(3b-3)=-b+6
open the bracket
3bz-3z=-b+6
make -b the subject of the formula
-b = 3bz-3z-6
-b - 3bz = -3z - 6
factorize the left hand side...
-b(1+3z) = -3z-6
make -b the subject of the formula again
-b = -(3z-6)/(1+3z)
cancel the minus at both sides...
b = (3z-6)/(1+3z)
Answer:
b = [tex]\frac{3z + 6}{3z+1}[/tex]
Step-by-step explanation:
Simply solve for "b" , so the formula will be
b = .....
z = [tex]\frac{-b+6}{3b-3}[/tex] ( b > 0 )
z(3b - 3) = - b + 6
3zb - 3z = - b + 6
3zb + b = 3z + 6
b( 3z + 1 ) = 3z + 6
b = [tex]\frac{3z + 6}{3z+1}[/tex]

On a coordinate plane, a curved line begins at point (1, 2) and ends at (5, 4).
What is the range of the function on the graph?
all real numbers
all real numbers greater than or equal to 0
all real numbers greater than or equal to 1
all real numbers greater than or equal to 2
Step-by-step explanation:
there must be something missing here (I guess, the graph).
because just by looking at the 2 points, all 4 answer options could be wrong, or all 4 could be right.
just basing on the point coordinates I see the functional values (y) go from 2 to 4.
but we have no clue about what that curved function does in between these 2 points.

What is the approximate result of converting 20 centimeters into inches? Remember that 1 inch = 2.54 centimeters.
Answer:
7.874 inches
Step-by-step explanation:
20/2.54=7.874
Answer:
7.87
Step-by-step explanation:
1/x = 2.54/20
2.54x = 20
x = 20/2.54
x = 7.87401574803
x = 7.87

Answer:
60cm
Step-by-step explanation:
(diagram with colors below)
The two red sides can be visualized as the same length as the length, so the two red segments add up to 18cm. The same thing can be said with the blue segments and the width. We can say the perimeter can be:
18 + 18 + 12 + 12 = 60cm

Answer: 24, b
Step-by-step explanation:
So it said "In the Math Club", 67% are not in the literature club. We also know that this 67% is 16 people.
Now we can set up an equation to find the total number of people in the math club. Let's say the total number of people in the Math club is x, so 0.67x = 17, and x = 25.37 rounded. So if 25 people in total, 16 not in the literature club, then that means 25-16 = 9 people are in both the Math club and the Literature club.
So of the students "Not in the Math Club", it said that 78 percent are not in the Literature Club. This means 22 percent are in the literature club. We also know 4 people are in the literature club.
Now we can set up an equation to find the total number of people not in the math club. Let's say the total number of people not in the Math club is x, so 0.22x = 4, x = 18.18 rounded. So if 18 in total, 4 in the literature club, than 14 not in the literature club.
Since x = 9, and y = 14, x+y will equal 23, rounding up to 24 since we rounded down the total number of people.

How would you find out how many sixth through eighth grade students are interested in joining a running club?
The question is incomplete. The complete question is :
How would you find out how many sixth through eighth grade students are interested in joining a running club? Explain how to choose a sample that will give you a good representation of a whole population.
Answer :
the sample should be random
Explanation :
We have to find the number of student from 6th through 8th grade students those who wanted to join a running club by choosing a sample of population. So in order to choose a sample which will provide a good representation for the whole population is that the sample must be a [tex]\text{random sample}[/tex] from [tex]\text{entire set of students }[/tex] and it should also include enough students to be reliable. The smaller samples have a more variation that lead to a lesser reliable inference.

Parallel Lines
PLEASE HELP I NEED ASAP!
Answer:
B
Step-by-step explanation:
The triangles do have equal angles and proportional sides, because they are bot right triangles formed on parallel lines.
:)ur welcome
Answer: Choice B
Yes. Right triangles formed on parallel lines have proportional side lengths and congruent angles.
====================================================
Explanation:
Parallel lines always have equal slopes, but different y intercepts.
Recall that slope = rise/run.
The "rise" is the vertical portion of the triangle, while the "run" is the horizontal portion.
So let's say we had a slope of rise/run = 2/3. This means rise = 2 and run = 3.
If we had something like rise/run = 4/6, then that reduces to 2/3, showing that 4/6 = 2/3. They are the same slope.
We can use the SAS similarity theorem to prove the triangles formed in the diagram are congruent based on what is discussed above.
Because the triangles are similar, this means the corresponding angles are congruent. One such pair is the pair of right angles shown.
Find two numbers if their Least Common Multiple, LCM is 100 and their Highest Common Factor, HCF is 5. Give two possible pairs of answers.
Step-by-step explanation:
Let H = HCF(A,B) and L = LCM(A,B)
Then A*B = L*H
Here L*H = 100*5 = 500
Also H <= A ,B <= L
So we need to find all A*B = 500, satisfying the above condition. This can be done using prime factorisation of 500.
Here 500 = 2^2 * 5^3
so possible values of A and B are
1 , 500
2, 250
4, 125
5,100
10,50
20,25
(assuming order doesn’t matter.)
so pairs satisfying given condition are → (20,25) and (100,5)

A line is perpendicular to y=2/3x+2/3 and intersects the point (-2,4). What is the equation of this perpendicular line?
Answer:
y = - [tex]\frac{3}{2}[/tex] x + 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = [tex]\frac{2}{3}[/tex] x + [tex]\frac{2}{3}[/tex] ← is in slope- intercept form
with slope m = [tex]\frac{2}{3}[/tex]
Given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{\frac{2}{3} }[/tex] = - [tex]\frac{3}{2}[/tex]
Using the point- slope form
with m = - [tex]\frac{3}{2}[/tex] and (x₁, y₁ ) = (- 2, 4) , then
y - 4 = - [tex]\frac{3}{2}[/tex] (x - (- 2) ) , that is
y - 4 = - [tex]\frac{3}{2}[/tex] (x + 2) ← distribute
y - 4 = - [tex]\frac{3}{2}[/tex] x - 3 ( add 4 to both sides )
y = - [tex]\frac{3}{2}[/tex] x + 1 ← in slope- intercept form
Find an equation for the line with slope m = -6/7 and which goes through the point (14, 4).
Answer:
A line with a slope of – that passes through the point (–14, 4)
Step-by-step explanation:
The equation of a line is typically written as y= mx+b where m is the slope and b is the y- intercept.

Select the interval where g is negative.
PLSSS HELLPPP!!!
The interval where g is negative is in the domain of -5 ≤ x < 1
The reason for the above selected interval is as follows;
A function is negative over an interval where the graph of the function is
below the x-axis, and the y-coordinate values are negative, excluding
where the y-value is zero. The interval over which a function is negative is
also called the negative region
From the given graph, the function, g(x), we have;
At x = 1, y = g(x) = 0
At x = -5, y = g(x) ≈ -7 and increasing to 0
Therefore at x = -5, g(x) ≈ -7, is negative
Tis negative over the interval -5 ≤ x < 1
Therefore;
The interval where g(x) is negative is -5 ≤ x < 1.
