Answer:
45
Step-by-step explanation:
Identify in the given expressions, terms which are not constants. Give their numerical coefficients.
(i) 5x – 3
(ii) 11 – 2y2
(iii) 2x – 1
Given:
The expression are
(i) [tex]5x-3[/tex]
(ii) [tex]11-2y^2[/tex]
(iii) [tex]2x-1[/tex]
To find:
The terms which are not constants and their numerical coefficients.
Solution:
Constants: The terms which are free from variables.
Numerical coefficient: Number multiplied with a variable.
(i) [tex]5x-3[/tex]
Constant = -3
Term which is not constant = 5x
Numerical coefficient = 5
(ii) [tex]11-2y^2[/tex]
Constant = 11
Term which is not constant = [tex]-2y^2[/tex]
Numerical coefficient = -2
(iii) [tex]2x-1[/tex]
Constant = -1
Term which is not constant = 2x
Numerical coefficient = 2
Therefore, the terms which are not constants are [tex]5x,-2y^2,2x[/tex] respectively and their numerical coefficients are 5, -2, 2 respectively.

−26xy+9x+9y
Step-by-step explanation:
Let's simplify step-by-step.
(−9x)(y)+9x−17xy+9y
=−9xy+9x+−17xy+9y
Combine Like Terms:
=−9xy+9x+−17xy+9y

Carla has $45. Pineapples cost $5 each and mangos cost $2 each. Let p stand for pineapples and let m stand for mangos. Write an inequality to show how many of each Carla can buy.
Answer
24
Step-by-step explanation:
2:2 = 8
45 / 5 = 168
168 - 45 = 123
123 - 45 = 78
78 take away the 7 is 8 , 8 x 5 = 40 / 8 = 24
Answer:
$5(p)+$2(m) ≤ $45
Step-by-step explanation:
If you have a maximum of 45 dollars you are only able to spend 45 dollars or less so the variables that are filled in with the amount of pineapples and mango´s Carla wants to buy must be less than or equal to 45
Given that L is a linear function, L (5) = 100 and L (9) = 150.
a. Determine the value of L (13)
Answer:
L(13) = 200
Step-by-step explanation:
Linear function:
A linear function has the following format:
[tex]y = mx + b[/tex]
In which m is the slope(how much y changes when x changes by 1) and b is the y-intercept(value of y when x = 0).
Finding the slope:
L (5) = 100 and L (9) = 150.
The slope is given by the change in the output(L, which is equals to y in the general formula) divided by the change in the input(x).
Change in the output: 150 - 100 = 50
Change in the input: 9 - 5 = 4
Slope: [tex]m = \frac{50}{4} = 12.5[/tex]
So
[tex]y = 12.5x + b[/tex]
L (5) = 100
So [tex]y(5) = 100[/tex], which means that when [tex]x = 5, y = 100[/tex], and we use this to find b.
[tex]y = 12.5x + b[/tex]
[tex]100 = 12.5*5 + b[/tex]
[tex]b = 100 - 12.5*5[/tex]
[tex]b = 37.5[/tex]
So
[tex]L(x) = 12.5x + 37.5[/tex]
a. Determine the value of L (13)
L when [tex]x = 13[/tex]. So
[tex]L(13) = 12.5*13 + 37.5 = 200[/tex]

[tex]b^{2}[/tex] is going to be -3 * -3 = 9
When you have a square you multiply the number by itself.
So
9 - 4 * 1 * -4
here you have to remember order of operations.
Please - Parens
Excuse - Exponents
My - Multiplication
Dear - Division
Aunt - Addition
Sally - Subtraction.
Multiplication and Division are done at the same time left to right
Addition and Subtraction are done at the same time left to right.
So
9 - 4 * 1 * -4
You do the multiplication first.
4*1 = 4
4 * -4 = -16
Now you have
9 - - 16
This turns into
9 + 16

complete the exponent chart
I'll do the first 6 rows to get you started.
===========================================
In row 1, we have the number [tex]2^3[/tex] which is the same as writing 2^3
The base is 2 and the exponent is 3. Think of "base" as in "basement" to remember that the base is under the exponent. The exponent tells us how many copies of the base to multiply out. In this case, we have three copies of the base "2" multiplied to get 2*2*2 = 8
============================================
In row 2, we have the number 3^2. The base is 3 and the exponent is 2.
We can say 3^2 = 3*3 = 9. We have two copies of the base multiplied. Think of a 3 inch by 3 inch square that has area of 9 square inches.
============================================
Row 3:
The number 5^4 means 5^4 = 5*5*5*5 = (5*5)*(5*5) = 25*25 = 625
The base is 5 and the exponent 4 tells us how many copies of the base to multiply.
============================================
Row 4:
We aren't given the number like in the earlier rows. But we can see that the base is 6 and the exponent is 2. So the number to fill in that first blank is 6^2
The expanded notation would be 6*6 because the exponent tells us how many copies of the base to multiply out.
The standard notation is 36 because 6*6 = 36.
============================================
Row 5:
This time we don't have an exponent, but we have the base and we have the expanded notation.
The expanded notation of 8*8*8 means the base is 8 and the exponent is 3
So 8^3 = 8*8*8 = 512
We'll have 8^3 to fill in the first blank of row five, 3 fill in the next blank, and finally 512 fill in the last blank.
============================================
Row 6:
We have six copies of '9' multiplied together
This tells us we have the number 9^6. The base is 9 and the exponent is 6
Use your calculator to determine that 9^6 = 9*9*9*9*9*9 = 531441
============================================
I'll let you do the rest of the remaining rows.
The police use a speed gun to monitor one part of a highway. During one hour, 4 out of 25 cars were traveling above the speed limit. What percent of cars were traveling above the speed limit.
Answer: 16%
Step-by-step explanation: Because if you look at that denominator then you can see that its 25 so if you multiplied that by 4 then you'll get 100 which is 100% so whatever you do to the denominator you have to do to the numerator so 4x4 is 16 so thats 16% and there you go.

Step-by-step explanation:
The dot plots below show the age of some dance students and some yoga students: Two dot plots are shown one below the other. The top and the bottom plots have the title Dance Students and Yoga Students respectively. Below the line for each dot plot is written Age followed by years in parentheses. The markings on each line are from 10 to 30 at intervals of 1. For the top plot there are two dots for 13 and 16 and 1 dot each for 12, 15, 17, 18, and 20. For the bottom plot there are 2 dots for 25 and 1 dot each for 17, 19, 20, 22, 24, 27, and 29. Based on visual inspection of the dot plots, which group of students appears to have the larger average age? The yoga students The dance students Both groups are similar. Not enough information is available to draw a conclusion.

6X + 8Y - 4Z = 5 1X + 2Y + 5Z = 9 9X - 3Y + 3Z = 6 resolverlo por metodo de Gauss jordan
Responder:
x = 4.48
y = 4.86
z = -1.04
Explicación paso a paso:
Dadas las ecuaciones simultáneas;
6X + 8Y - 4Z = 5 .... 1
1X + 2Y + 5Z = 9 ... 2
9X - 3Y + 3Z = 6 .... 3
Primero necesitamos reducir el sistema de ecuaciones
Ecuación 1 * 1
Ecuación 2 * 4
__________
6X + 8Y - 4Z = 5
4X + 8Y + 20Z = 36
Restar
6x-4x - 4z-20z = 5-36
2x-24z = 31 ... 4
también
ecuación 2 * 3
ecuación 3 * 2
_______________
1X + 2Y + 5Z = 9 * 3
9X - 3Y + 3Z = 6 * 2
_______________
3x + 6y + 15z = 27
18x - 6 años + 6z = 12
Agregar
3x + 18x + 15z + 6z = 27 + 12
21x + 21z = 39 ...... 5
Resolviendo 4 y 5
2x-24z = 31 ... 4 * 21
21x + 21z = 39 ...... 5 * 2
____________
42x - 504z = 651
42x + 42z = 78
Sustraer
-504x - 42z = 651-78
-546z = 573
z = -573/546
z = -1.05
Sustituye z = -1.05 en 4
De 4;
2x-21z = 31
2x - 21 (-1,05) = 31
2x + 22,04 = 31
2x = 31-22.04
2x = 8,96
x = 8,96 / 2
x = 4,48
Obtener y
De 2:
X + 2Y + 5Z = 9
4.48 + 2y + 5 (-1.04) = 9
2 años + 4,48-5,2 = 9
2y = 9 + 0,72
2 años = 9,72
y = 9,72 / 2
y = 4,86
Por tanto, la solución (x, y, z) es (4.48, 4.86, -1.04)
