Solve the system below by substitution.
6x - y = - 23
2x + 5y = -13
Answer:
x= -4 y= -1
Step-by-step explanation:
6x - y = - 23
-y=-23-6x
y=6x+23, use this to plug in for y in the second equation.
2x + 5y = -13
2x + 5(6x+23) = -13
2x+30x+115=-13
x= -4, use this to plug in for x in the first equation.
6x - y = - 23
6(-4)-y=-23
-24-y=-23
-y=-23+24
-y=1
y= -1
The values after solving the equations by substitution is that the value of x is -4 and the value of y is -1.
What is an arithmetic operation?The four fundamental operations of arithmetic are addition, subtract, multiply, and division of two or more numbers. Included in them is the study of integers, especially the order of operations, which is important for all other aspects of mathematics, notably algebra, information management, and geometry.
As per the provided data in the question,
6x - y = -23 (i)
2x + 5y = -13 (ii)
Multiply equation (ii) by 3
6x + 15y = -39 (iii)
Solve equation (i) and (iii)
-16y = 16
y = -1
Substitute y = -1 in equation (i)
6x = -23 - 1
x = -4.

The seats on the right side of the school bus fit two students each. The seats on the left side of the school bus can fit three students each. There are 14 rows of seats. Eight students can fit in the very back seat. How many people can ride the bus at one time (Remember to count every person)?
Answer:
79
Step-by-step explanation:
From Question, we are told that, there are 14 rows of seat with is divided into left hand side and right hand side
Seats by the right = fit two people
Seats by the left = fit three people
This means, 1 row of seat can contain 5 persons
The back seat = 8 people can sit comfortably.
Hence, the number of people that can ride the bus at one time =
(14 × 5 people) + 8 people (backseat) + 1 driver
= 70 + 8 + 1
= 79 people

The sum of two numbers is 48. If the second number is 6 less than the first, what
is the value of EACH of the numbers?
Answer:
let the first no. be x
then the second no. = x - 6
their sum is 48
therefore,
[tex] = > x + (x - 6) = 48 \\ = > 2x = 48 + 6 \\ = > 2x = 54 \\ = > x = \frac{54}{2} \\ = > x = 27[/tex]
The value of first no. = x = 27
The value of second no. = x - 6 = 27 - 6
= 21

Step-by-step explanation:
(a)
There is a common difference d between consecutive terms, that is
d = 12 - 0 = 24 - 12 = 36 - 24 = 48 - 36 = 12
This indicates the sequence is arithmetic with common difference 12
(b)

Over the course of a month, caught three times as many squirrels as deer. She also caught five less rabbits than squirrels. The total number of animals she caught is ten more than four times the number of deer caught. How many rabbits did Katniss catch?
Answer:
The number of rabbits Katniss caught = 10 rabbits
Step-by-step explanation:
The number of squirrels Katniss caught = 3 × (The number of deer she caught)
The number of rabbits Katniss caught = The number of squirrels she caught - 5
The total number of animals she caught = 10 + 4 × (The number of deer she caught)
Let the number of deer Katniss caught = D
∴ The number of squirrels she caught = 3×D
The number of rabbits Katniss caught = 3×D - 5
The total number of animals she caught = 10 + 4 × D
Therefore, we have;
The number of squirrels she caught + The number of deer she caught + The number of rabbits she caught = 10 + 4 × D
3×D + D + 3×D-5 = 10 + 4 × D
7·D - 5 = 10 + 4·D
7·D - 4·D = 10 + 5
3·D = 15
D = 15/5 = 5
∴ The number of deer Katniss caught = D = 5
The number of rabbits Katniss caught = 3×5 - 5 = 10
The number of rabbits Katniss caught = 10 rabbits.
The function g(x) is a transformation of the cube root parent function, f(x) = \sqrt[3]{x}f(x). What function is g(x)?
Answer: D
Step-by-step explanation:
First, remember two things about translations.
For a function f(x).
A horizontal translation to the right of N units is written as:
f(x - N)
A vertical translation up of N units is written as:
f(x) + N.
Now let's look at the graph.
You can see that:
g(x) is: 4 units at the right of f(x) and 3 units bellow f(x).
Then we have:
g(x) = f(x - 4) - 3.
and f(x) = ∛x
then g(x) = ∛(x - 4) - 3
The correct option is D.
The function g(x) is transformed from the function f(x) by translating function f(x) by 4 units in the right direction and then by translating that graph 3 units in a downward direction.
Given :
Function -- [tex]\rm f(x) = \sqrt[3]{x}[/tex]
The following steps can be used to determine the unknown function g(x):
Step 1 - According to the given graph, translate function f(x) 4 units in the positive x-axis that is in the right direction.
Step 2 - Now, again according to the given graph, translate function f(x) 3 units in the downward direction that is in the negative y-axis.
Step 3 - The resulting graph is the graph of the function g(x). Whose equation is written as:
[tex]\rm g(x) = \sqrt[3]{x-4} - 3[/tex]
So, the correct option is D).

Answer:
60 cm
Step-by-step explanation:
remember, the area of a triangle is found by
1/2 b h
or half of the base times the height
so using that plug in the values:
the base is made of two 5s; 2* 5 is 10 so the base is 10cm long
the height is 12cm
so
1/2 * 12 * 10
= 6 * 10
= 60
Answer:
I think its 60
Step-by-step explanation:
To find the area of a triangle you do (height x base) divided by 2
5+5=10
12 x 10 = 120
120 divided by 2 is 60

roberto garcia ha jugado en las ligas menores durante 11 años. el total de jonrones en cada año ha sido de: 56,62,49,65,58,52,68,72,25,64. ¿Cuantos jonrones necesita Roberto para que la próxima temporada pueda tener una media de 60 en 12 años?
Los puntos de datos dados son 10
Responder:
89 jonrones
Explicación paso a paso:
Dados los datos:
Datos de jonrones durante 11 años:
56,62,49,65,58,52,68,72,25,64
Para promediar 60 jonrones en 12 años:
Tome la media de los datos, utilizando una incógnita para el Número de jonrones en el año 12:
[(56 + 62 + 49 + 65 + 58 + 52 + 68 + 72 + 25 + 64 x) / 11] = 60
[(571 + x) / 11] = 60
571 + x = 60 * 11
571 + x = 660
x = 660 - 571
x = 89
Solve the inequality 5x + 3 > 48
Answer:
Step-by-step explanation:

5x > 48 - 3
5x > 45
x > 45/ 5
x > 9
Answer:
x = 9
Step-by-step explanation:
5x + 3 > 48
Subtract 3 to both sides
5x > 45
Divide by 5 to both sides
x = 9
To check if the answer is correct, you can always plug in 9 instead of x and solve the equation.
