Expression:
A mathematical symbol, or combination of symbols, representing a value, or relation. Example: 2 + 2 = 4
-11y = 6(2+1) - 13y
4y - 24 = c(z – 1)
For what value of c does the above system of linear equations in the variables y and z have
infinitely many solutions?
Answer:
12
Step-by-step explanation:
Let's put the equations in standard form. For the first equation, we have:
−11y=6(z+1)-13y
2y−6z=6
y−3z=3
The second equation is:
4y−24=c(z−1)
4y−cz=24−c
If we multiply the first equation by 4, we get:
4y-12z=12
Comparing the two equations, we see that if c=12, both equations will be the same and there will be infinitely many solutions.
The correct value of c is 12.
Last month, when Joe took his puppy to the veterinarian, the puppy weighed 5.5 pounds. This month, the puppy weighed 7.15 pounds. What is the percentage increase of the weight of the puppy?
Answer:

Calculate the value
of the unknown
coefficient b of a
quadratic equation
when the
discriminant of that
equation is known.
3x² + bx + 2 = 0; Coefficient = 12
Answer:
The value of b is either + 6 or -6
Step-by-step explanation:
Here, given that we have the value for the discriminant, we want to calculate the value for the coefficient of x
mathematically, the discriminant can be calculated using the equation;
D = b^2 - 4ac
a represents the coefficient of x^2 which is 3
b represents the coefficient of x given as b
2 represents the last number
D is the discriminant = 12
So we have that;
12 = b^2 - 4(3)(2)
12 = b^2 - 24
b^2 = 24 + 12
b^2 = 36
b = √36
b = +6 or -6
A car is purchased for £11 500 In its first year, the value of the car will depreciate by 15%. Each year after that, the value of the car will depreciate by 10%. What is the value of the car at the end of 3 years?
Answer:
Value of the car at the end of 3 years is £7917.75
Step-by-step explanation:
The car is purchased for £11500.
In the first year, 15% depriciation.
So, depreciation on first year =11500 *[tex]\frac{15}{100}[/tex] =1725
After first year depreciation the value of car =11500-1725 =£9775
Now, second year depreciation is 10%
So, 10% of 9775 =0.10*9775 =977.5
Value of car after 2 years = 9775 -977.5 =8797.5
Now, for third year depreciation is 10%.
So, depreciation on 3 year = 10% *8797.5
=0.10*8797.5
=879.75
So, value of car after 3 years = 8797.5 -879.75 =£7917.75

Encontrar las coordenadas del centro y la longitud del radio de la circunferencia 9x²+9y²+18x-12+10=0
Answer:
Step-by-step explanation:
The standard form of equation of a circle is expressed as;
x^2+y^2+2gx+2fy+c = 0
The centre is at (-g, -f)
Given the equation'
9x²+9y²+18x-12+10=0
Divide through by 9
9x²/9+9y²/9+18x/9-12y/9+10/9=0
x^2+y^2+2x-4/3 y + 10/9 = 0
Compare
2gx = 2x
g = 1
2fy = -4/3 y
2f = -4/3
f = -4/6
f = -2/3
The centre is (-(-2/3), -1) = (2/3, -1)
for the radius
r = √f²+g²-c
r =√(-2/3)²+1²-10
r =√4/9 - 9
r = √(4-81)/9
r = √-77/9

The chess club has a budget of at least $300 that the members can spend for the field trip. There are 20 people in the chess club. They get a discount of $60 for transportation for the field trip. What is the minimum that each member
of the chess club can spend on the trip?
Answer:
$12
Step-by-step explanation:
We are told that there are 20 people in the chess club and each got a discount of $60 for transportation on the field trip.
Let the amount spent by each member is x
Since there are 20 of them and the budget is at least $300 and they get a discount of $60, it means that;
20x ≥ 300 - 60
20x ≥ 240
Divide both sides by 20 to get;
x ≥ 12
Thus, minimum amount each member can spend is $12.
What is the first step to solving the equation 12 - y = 18?
Answer:
subtract 12 from 18
Step-by-step explanation:
Answer:
No real "first step" as there are many ways to do it. If I were to do it, I would add the y to the other side to make it positive. This thus eliminates any negative variables in the equation

The area of a bookmark is 140 square centimeters. The perimeter is 54 centimeters. What are the dimensions of the bookmark?
Answer:
See explanation
Step-by-step explanation:
Recall that all the sides of the square are equal
Hence;
Area of a rectangle= l * b ------- equation 1
Perimeter of a rectangle = 2(l + b)----------equation 2
Area of the rectangle = 140 square centimeters
140 = lb
l = 140/b
Perimeter of the rectangle = 54 centimeters
substituting l = 140/b into equation 2
54 = 2(140/b + b)
Multiplying through by b
54b = 280 + 2b^2
Hence;
2b^2 - 54b + 280 = 0
Solving the quadratic equation
b=20 or b=7
substituting b=20 or b=7 into l = 140/b
l = 140/20 or l = 140/7
l = 7 or 20
THEREFORE;
b=20 cm or b=7 cm
l = 7cm or 20cm

Nakato Nobuki, a Japanese artist, intends to withdraw $ 24,000.00 from his savings at the end of 5 years. Mr. Nobuki deposits $ 1,500.00 in savings annually and today has a balance of $ 8,000.00. What should be the savings interest rate for Nobuki to achieve his goals?
Answer:
The savings interest rate of Nakato Nobuki is 3 %
Step-by-step explanation:
Given;
Final amount of Nakato Nobuki, A = $ 24,000.00
time period of his investment, t = 5 years
principla amount, P = $ 1,500.00
The savings interest rate of Nakato Nobuki can be calculated on a simple interest basis.
A = P(1 + rt)
r is the savings interest rate
Substitute the given values and solve for r
24,000 = 1,500(1 + 5r)
24,000 = 1,500 + 7,500r
7,500r = 24,000 - 1,500
7,500r = 22,500
r = 22,500/7,500
r = 3 %
Therefore, the savings interest rate of Nakato Nobuki is 3 %

Does the table below represents a linear function why or why not
Answer:
No, it's not linear function.
Step-by-step explanation:
The x value repeatedly adds 3.
So far its a linear function.
If you look at the y value, it does NOT have a pattern, therefore that means it is NOT a linear function.

The sum of the
First n terms of a linear
sequence is
ce is
[tex]2 - 7 {n}^{2} [/tex]
, find the second term
Answer:
-21
Step-by-step explanation:
Given the sum of the first n term as;
Sn = 2 - 7n^2
The nth term is expressed as;
Tn = Sn - Sn-1
Sn-1 = 2 - 7(n-1)^2
Tn = 2 - 7n^2 - (2 - 7(n-1)^2)
Tn = -7n^2 + 7(n-1)^2
To get the second term, we will substitute n = 2 into the resulting expression
T2 = -7(2)^2 + 7(2-1)^2
T2 = -7(4)+7(1)^2
T2 = -28 + 7
T2 = -21
Hence the second term of the sequence is -21

The range of the given function from the given graph are: all values of y that are greater than or equal to -3. Therefore, the correct option is option D.
What is range of function?It is seen to be best practice to define the word "range" the first time it appears in a book or article because it might have several different meanings. When the word "range" is used in older literature, it frequently refers to what is today known as the codomain.
If more recent texts use the phrase "range" at all, they typically do so to refer to what is now known as the image. Several contemporary novels shouldn't use the term "range" at all to avoid any misunderstandings.
A function's range is the set of each of its potential outputs1,2,3,4. That's the output that the function generates when all of its inputs are used3,5. The range of the given function from the given graph are: all values of y that are greater than or equal to -3.
Therefore, the correct option is option D.

what can you double and then add -6 to get -16
Answer:
- 5
Step-by-step explanation:
let the number be n then double is 2n , so
2n + (- 6) = - 16
2n - 6 = - 16 ( add 6 to both sides )
2n = - 10 ( divide both sides by 2 )
n = - 5
The number is - 5

Answer:
C
Step-by-step explanation:
(0,-4) (-4, -3)
-3- -4 / -4 -0 = 1/-4 is the slope
so is C
Answer:
The answer is B.
Step-by-step explanation:
slope-intercept form is y=mx + b with m being slope and b being y-intercept. slope is change in y over change in x, and in this situation the change in y is 1 and the change in x is 4. so, slope = 1/4. so now our equation is y=1/4x+b. now we have to find the y-intercept, which in this graph is -4. so, the equation is y=1/4x+-4.
