Answer:
The equation of the Parallel line passes through the point (-1,4) is
y = -5 x -1
Step-by-step explanation:
Explanation:-
Given the equation of the line y = -5 x + 2
Given point (-1 , 4 )
The equation of the parallel line of a given line is 5x + y +k=0 ...(i)
The equation (i) passes through the point (-1,4)
5(-1)+4+k=0
-5 +4 +k =0
-1 + k = 0
k = 1
The equation of the Parallel line passes through the point (-1,4) is
y = -5 x -1

Answer:
1.8181818181818181 etc., which rounds to 1.82
Step-by-step explanation:
1.65/3 = 1/x
3/1.65
We get 1.80 pounds of flour for 1 dollar.
What is unitary method ?Unitary method is a mathematical technique for first deriving the value of a single unit then deriving any given unit from it.
Suppose we know one mango costs 4 dollars so 20 mangoes will cost (4×20) dollars = 80 dollars.
According to the given question three pounds of flour cost 1.65 dollars.
So, One pound of flour will cost (1.65/3) dollars which is
= 0.55 dollars.
In 1 dollar we will get (1/0.55) pounds of flour which is
= 1.81 pounds.
Rounding 1.81 to nearest hundredth will be 1.80 as the rightmost digits is than 5.

Step 1: Define
250 = 4(1 - 7x)
Step 2: Solve for x
Divide both sides by 4: 125/2 = 1 - 7xSubtract 1 on both sides: 123/2 = -7xDivide -7 on both sides: -123/14 = xRewrite: x = -123/14Step 3: Check
Plug in x into the original equation to verify it's a solution.
Substitute in x: 250 = 4(1 - 7(-123/14))(Parenthesis) Multiply: 250 = 4(1 + 123/2)(Parenthesis) Add: 250 = 4(125/2)Multiply: 250 = 250Here we see that 250 does indeed equal 250.
∴ x = -123/14 is the solution to the equation.

Step-by-step explanation:
Given
[tex]Sequence = \{3, 6, 12, 24, 48...\}[/tex]
Required
Determine the sum of the first terms
First, we calculate the common ratio (r)
[tex]r = \frac{T_2}{T_1}[/tex]
[tex]r = \frac{6}{3}[/tex]
[tex]r = 2[/tex]
The required sum is:
[tex]S_n = \frac{a(r^n-1)}{r-1}[/tex]
Substitute 3 for a, 2 for r and 10 for n
[tex]S_{10} = \frac{3(2^{10}-1)}{2-1}[/tex]
[tex]S_{10} = \frac{3(1024-1)}{2-1}[/tex]
[tex]S_{10} = \frac{3(1023)}{2-1}[/tex]
[tex]S_{10} = \frac{3(1023)}{1}[/tex]
[tex]S_{10} = \frac{3069}{1}[/tex]
[tex]S_{10} = 3069[/tex]

What is a linear equation?A relationship between two or more parameters that, when shown on a graph, produces a linear model. The degree of the variable will be one.
The linear equation is given as,
y = mx + c
Where m is the slope of the line and c is the y-intercept of the line.
The equation of the line is given below.
y = -0.5x + b
The line is passing through (4, 4), then the value of b will be
4 = -0.5 × 4 + b
4 = - 2 + b
b = 4 + 2
b = 6
Then the equation will be
y = - 0.5x + 6
The equation is passing through (3, p), then the value of p will be
p = -0.5 × 3 + 6
p = - 1.5 + 6
p = 3.5
The equation is passing through (7, n), then the value of n will be
n = -0.5 × 7 + 6
n = - 3.5 + 6
n = 2.5
Then the value of the variables b, p, and n will be 6, 3.5, and 2.5, respectively.

7. Factor each quadratic expression,
Step-by-step explanation:
x² - 2x - 35 = (x - 7)(x + 5).
x² + 3x - 54 = (x + 9)(x - 6).
x² - 4x + 4 = (x - 2)².
x² - 121 = (x + 11)(x - 11).
2x² + x - 15 = (2x - 5)(x + 3).
6x² - 7x - 24 = (3x - 8)(2x + 3).
3x² - 10x + 8 = (3x - 4)(x - 2).
10x² + 9x - 9 = (5x - 3)(2x + 3).
12x² + 25x + 12 = (4x + 3)(3x + 4).
15x² - x - 6 = (5x + 3)(3x - 2).

Graph
y + 4 = 2/5 (x − 3)
Answer:
Y= 2/5x - 23
Step-by-step explanation:
Firstly:
Move the 1/5 to the other side of the equation
So
5(y+4) =2(x-3)
Secondly:
Expand the brackets
5y +20 = 2x-3
Thirdly:
Solve
5y= 2x - 3-20
5y=2x-23. (Divide by five both sides)
Y= 2/5 x - 23 (Straight line graph)

Answer:
the first one n + 8 < -2 is correct, the second one is correct too, but its just the graph that is wrong. n > -3, since its greater, it should increase in number, so the line would go toward the right, the opposite direction you drew down.

Mrs. Fuller is trying to organize all of her children's toys into a large toy box. Each toy
has the dimensions of 4 inches x 3 inches x 3 inches. The toy box measures 4 feet x 2
feet x 3 feet. How many toys will be stored in the large toy box?
Answer: 1,152 toys can be stored in the box.
Step-by-step explanation:
For an object with measures L (length) by W (width) by H (height) the volume is calculated as:
V = L*W*H
We know that the measures of each toy are: 4in x 3in x 3in
Then the volume of each toy is:
V = 4in*3in*3in = 36in^3
The toy box is 4ft x 2ft x 3 ft
First we should write the measures in the same units as before, we know that:
1ft = 12 in.
Then:
4ft = 4*12 in = 48 in
2ft = 2*12in = 24in
3ft = 3*12in = 36in
Then the measures of the box are:
48in x 24in x 36in
Then the volume of the box is:
V = 48in*24in*36in = 41,472 in^3
Now, the number of toys that can be stored in the box is the same as the number of times that 36in^3 is in 41,472 in^3
this is equal to the quotient between 41,472 in^3 and 36in^3
N = 41,472 in^3/36in^3 = 1,152
1,152 toys can be stored in the box.
