Answer:
z=1/4
Step-by-step explanation:
z-(1/5)=z(1/5)
z-(1/5)=z/5
5z-(5/5)=z
5z-1=z
-1=-4z
1/4=z
Therefore, z=1/4
The value of z for the given condition is given by 1/4.
What is an Equation?Equation is a mathematical relation between more than one variable, number or mathematical quantities involving mathematical operations using equal sign in between them.
Here the given mathematical condition is that the difference of z and one fifth is the same as the product of z and one fifth.
One fifth is = 1/5
Difference between z and one fifth is given by = z-1/5
Product of z and one fifth is given by = z*(1/5) = z/5
So according to the condition the mathematical equation would be,
z-1/5 = z/5
z-z/5 = 1/5
(5z-z)/5 = 1/5
4z/5 = 1/5
4z = 5*(1/5)
4z = 1
z = 1/4
Hence the required value of z is 1/4.

Answer:
28. x=6 29. x=15 30. -56/5 31. -3 32. -10 33. 9.6
Step-by-step explanation:
The statement "y varies inversely as x" means that there is a constant (a number that doesn't change) k so that
[tex]y=\frac{k}{x}[/tex]
28. y = 12 when x = 3, so [tex]12=\frac{k}{3} \Rightarrow k=(12)(3)=36[/tex]. Now that you know the value of k (in THIS problem!), plug in 6 for y to find x.
[tex]6=\frac{36}{x}\\6x=36\\x=6[/tex]
All these problems work the same way.
29. [tex]5=\frac{k}{6} \Rightarrow 5(6)=k \Rightarrow k=30[/tex] Then, [tex]2=\frac{30}{x} \Rightarrow 2x = 30 \Rightarrow x=15.[/tex]
30.
[tex]4=\frac{k}{14} \Rightarrow (4)(14)=k \Rightarrow k=56\\-5=\frac{56}{x} \Rightarrow -5x=56 \Rightarrow x = -\frac{56}{5}[/tex]
31.
[tex]9=\frac{k}{9} \Rightarrow 81=k\\\\y=\frac{81}{-27}=-3[/tex]

Answer:
f(10) = 3
Step-by-step explanation:
If f(x) = [tex]-\frac{3}{5} x + 9[/tex] , in order to find the result for f(10) we just need to substitute 10 instead of x and we will get...
[tex]f(x) = -\frac{3}{5} x + 9\\\\f(10) = -\frac{3}{5} (10) + 9\\f(10) = - 6 + 9\\f(10) = 3[/tex]

Answer:
m =(-7-√73)/2=-7.772
Step-by-step explanation:
Answer:
m=−7/2+1/2√73 or m=−7/2+−1/2√73
Step-by-step explanation:
Let's solve your equation step-by-step.
m2=−7m+6
Step 1: Subtract -7m+6 from both sides.
m2−(−7m+6)=−7m+6−(−7m+6)
m2+7m−6=0
For this equation: a=1, b=7, c=-6
1m2+7m+−6=0
Step 2: Use quadratic formula with a=1, b=7, c=-6.
m=−b±√b2−4ac/2a
m=−(7)±√(7)2−4(1)(−6)/2(1)
m=−7±√73/2
m=−7/2+1/2√73 or m=−7/2+−1/2√73

If you were to use the “Completing the Square” method to solve the equation below for k, what number would you add to both sides of the equation? k 2- 8k = -4
A) 16
B) –16
C) 24
D) –24
Answer:
The number you would add to both sides of the equation to use the "Completing the Square" method would be 16.
Step-by-step explanation:
To find the number to add to both sides of an equation to complete the square, divide the first-degree term's coefficient by 2 and square your remainder. In this case, the coefficient of the first-degree term is -8. After dividing by 2 and squaring it, you'll get 16, so that is the number you must add to both sides of the equation in order to complete the square.

Step-by-step explanation:
Rule for the transformation of a point [tex]R_{x=1}(P)[/tex] defines,
Reflection of a point P(x, y) about a line, x = 1 which is parallel to y-axis.
Line x = 1 works like a mirror so the distance between the line and the image point will be equal to the distance between the line and the original point.
Distance between the line and a point (-1, 5) = 4
Therefore, distance between the line and the image point = 4

2 regular pizzas and 3 small pizzas cost £22 6 regular pizzas and 12 small pizzas cost £78
find the cost of one each
Answer:
Regular pizza: £5
Small pizza: £4
Step-by-step explanation:
Let x = regular pizza
Let y = small pizza
6x + 12y = 78
2x + 3y = 22
I'm going to use elimination method to solve for y
6x + 12 y = 78
-3(2x + 3y = 22) = -6x -9y = -66
Eliminate the x
3y = 12
Divide both sides by 3
3y/3 = 12/3
y = 4
Substitute the y in one of the original equations
2x + 3(4) = 22
2x + 12 = 22
Subtract both side by 12
2x + 12 - 12 = 22 - 12
2x = 10
Divide both sides by 2 to solve for x
2x/2 = 10/2
x = 5
Answer:
small $3.4 regular $6.2
Step-by-step explanation:
2r +3s = 22.6
6r *12s = 78
Multiply the first by -3
-6r -9s = -67.8
6r +12 s = 78
Add both (6r will be cancelled)
3s = 10.2
s = 3.4 small = 3.4 (3 small = 10.2)
2r +10.2 = 22.6
2r = 12.4
r = 6.2

Harmon’s Jewelry Store receives a shipment of jewelry. 485 pieces are good but 15 pieces arrived damaged. At this rate, if Mrs. Harmon places an order of 5,500 jewelry pieces, how many can she expect to be damaged?
hope this helps
Step-by-step explanation:
first you divide 5,500 by 485(5,500/485), then you will get 11.34, and since you cannot buy half of something, you will have to round down to 11. then you multiply 11 by 15 (11 X 15) and you will get 165, so then you go back and subtract 165 from 5,500 (5,500-165) and there is your answer (5335).

=> x² + 3x - 2x - 6 = 0 or x = 0
=> x(x + 3) - 2(x + 3) = 0 or x = 0
=> (x + 3)(x - 2) = 0 or x = 0
=> x = - 3 or x = 2 or x = 0
