Answer:
y = -3x - 11
Step-by-step explanation:
Use the given slope and point in the point-slope equation. Solving this will give us the y-intercept equation.
Point-slope formula: y - y = m(x - x)
Plug in the slope and point
y - (-5) = -3(x - (-2))
Subtracting negatives will make them positive. Multiply out the -3 to what is in the parentheses.
y + 5 = -3x - 6
Subtract the 5 from both sides
y = -3x - 11
The equation of the line is y = -3x - 11

A or x = 1
Step-by-step explanation:
So we can see from the most right column that the sum of the three number is 9 (2 + 4 + 3) so we know that every row or column has to add up to 9. We want to find x so we must make sure that, 8 + 0 + x should be 9 and 2 + 6 + x should be 9. From 8 + 0 + x, we know that 8 + 1 is 9 so x is 1. We can also see that 2 + 6 is 8 and 8 + 1 is 9 so x = 1.

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 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).

[(56 + 62 + 49 + 65 + 58 + 52 + 68 + 72 + 25 + 64 x) / 11] = 60
[(571 + x) / 11] = 60

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.

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
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

Write the standard form of the line that passes through the given points (1, 1) and (3, 4)
see what should to do buddy :
step 1-
first we have to find the gradient of the line like this:
a ( 1 , 1 )
b ( 3 , 4 )
.
step 2-
now just need one of the a or b point to put in this equation :
.
step 3-
to find the standard form of the line we have to take the y alone.
so we add the sides of the equation plus 1.
[tex]y = \frac{3}{2}x - \frac{3}{2} + 1 \\ \\ \\ y = \frac{3}{2}x - \frac{1}{2} [/tex]

Standard form of the line passing through points (1, 1) and (3, 4) is
y = (3 / 2)x - (1 / 2).
What is line?
"Line is a one dimensional figure which has only one dimension that is length no other dimension present in it."
Formula used
( x₁ , y₁) and (x₂ , y₂) are the two points through which line passes
[tex]\frac{x-x_{1} }{x_{2} -x_{1} } =\frac{y-y_{1} }{y_{2} -y_{1} }[/tex]
According to the question,
Given ,Line passes through points( 1, 1 )and (3,4)
Substitute the value in the formula to get standard form of line we get,
[tex]\frac{x-1 }{3 -1} =\frac{y-1 }{4 -1 }[/tex]
⇒3(x -1) = 2(y -1 )
⇒3x -3 = 2y -2
⇒y = (3/2)x - (1/2)
Hence, standard form of the line passing through points (1, 1) and (3, 4) is
y = (3 / 2)x - (1 / 2).
