The value of the function f (x) = 5x + 1 at x equal to zero will be 1.
What is a function?A function is defined as the expression that set up the relationship between the dependent variable and independent variable. Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
The given function is f (x) = 5x + 1. The value of the function at x equal to 0 will be calculated as below:-
f (x) = 5x + 1
f (0) = 5 x 0 + 1
f (0) = 0 + 1
f (0) = 1
Therefore, the value of the function f (x) = 5x + 1 at x equal to zero will be 1.

Stephen, Paul & Bridget share some money in the ratio 3 : 4 : 2.
In total, Stephen and Bridget receive £50.
How much does Paul get?
Answer:
£40.
Step-by-step explanation:
In terms of ratio units, Stephen and Bridget together get 3+2 = 5, while Paul receives 4. That is, Paul gets 4/5 of their combined total, or ...
4/5 · £50 = £40
Paul gets £40.
Given parameters:
Ratio of their money = 3 : 4 : 2
Total amount received by Stephen and Bridget = 50
Unknown :
How much did Paul get = ?
Solution:
The amount Paul got is a fraction of the total.
We need to find the total amount first;
Amount Stephen and Bridget got = [tex]\frac{ratio of stephen and bridget}{total ratio} x total amount[/tex]
let the total amount = y;
50 = [tex]\frac{3+2}{9}[/tex] x y
[tex]\frac{5y}{9}[/tex] = 50
5y = 450
y = 90
Now, the amount Paul got;
= [tex]\frac{4}{9} x 90[/tex]
= 40
The amount Paul got is £40

Write a matrix representing the system of equations
Answer:
[tex](4, -1, 3)[/tex]
Step-by-step explanation:
We have the system of equations:
[tex]\left\{ \begin{array}{ll} x+2y+z =5 \\ 2x-y+2z=15\\3x+y-z=8 \end{array} \right.[/tex]
We can convert this to a matrix. In order to convert a triple system of equations to matrix, we can use the following format:
[tex]\begin{bmatrix}x_1& y_1& z_1&c_1\\x_2 & y_2 & z_2&c_2\\x_3&y_2&z_3&c_3 \end{bmatrix}[/tex]
Importantly, make sure the coefficients of each variable align vertically, and that each equation aligns horizontally.
In order to solve this matrix and the system, we will have to convert this to the reduced row-echelon form, namely:
[tex]\begin{bmatrix}1 & 0& 0&x\\0 & 1 & 0&y\\0&0&1&z \end{bmatrix}[/tex]
Where the (x, y, z) is our solution set.
Reducing:
With our system, we will have the following matrix:
[tex]\begin{bmatrix}1 & 2& 1&5\\2 & -1 & 2&15\\3&1&-1&8 \end{bmatrix}[/tex]
What we should begin by doing is too see how we can change each row to the reduced-form.
Notice that R₁ and R₂ are rather similar. In fact, we can cancel out the 1s in R₂. To do so, we can add R₂ to -2(R₁). This gives us:
[tex]\begin{bmatrix}1 & 2& 1&5\\2+(-2) & -1+(-4) & 2+(-2)&15+(-10) \\3&1&-1&8 \end{bmatrix}\\\Rightarrow\begin{bmatrix}1 & 2& 1&5\\0 & -5 & 0&5 \\3&1&-1&8 \end{bmatrix}[/tex]
Now, we can multiply R₂ by -1/5. This yields:
[tex]\begin{bmatrix}1 & 2& 1&5\\ -\frac{1}{5}(0) & -\frac{1}{5}(-5) & -\frac{1}{5}(0)& -\frac{1}{5}(5) \\3&1&-1&8 \end{bmatrix}\\\Rightarrow\begin{bmatrix}1 & 2& 1&5\\ 0 & 1 & 0& -1 \\3&1&-1&8 \end{bmatrix}[/tex]
From here, we can eliminate the 3 in R₃ by adding it to -3(R₁). This yields:
[tex]\begin{bmatrix}1 & 2& 1&5\\ 0 & 1 & 0& -1 \\3+(-3)&1+(-6)&-1+(-3)&8+(-15) \end{bmatrix}\\\Rightarrow\begin{bmatrix}1 & 2& 1&5\\ 0 & 1 & 0& -1 \\0&-5&-4&-7 \end{bmatrix}[/tex]
We can eliminate the -5 in R₃ by adding 5(R₂). This yields:
[tex]\begin{bmatrix}1 & 2& 1&5\\ 0 & 1 & 0& -1 \\0+(0)&-5+(5)&-4+(0)&-7+(-5) \end{bmatrix}\\\Rightarrow\begin{bmatrix}1 & 2& 1&5\\ 0 & 1 & 0& -1 \\0&0&-4&-12 \end{bmatrix}[/tex]
We can now reduce R₃ by multiply it by -1/4:
[tex]\begin{bmatrix}1 & 2& 1&5\\ 0 & 1 & 0& -1 \\ -\frac{1}{4}(0)&-\frac{1}{4}(0)&-\frac{1}{4}(-4)&-\frac{1}{4}(-12) \end{bmatrix}\\\Rightarrow\begin{bmatrix}1 & 2& 1&5\\ 0 & 1 & 0& -1 \\0&0&1&3 \end{bmatrix}[/tex]
Finally, we just have to reduce R₁. Let's eliminate the 2 first. We can do that by adding -2(R₂). So:
[tex]\begin{bmatrix}1+(0) & 2+(-2)& 1+(0)&5+(-(-2))\\ 0 & 1 & 0& -1 \\0&0&1&3 \end{bmatrix}\\\Rightarrow\begin{bmatrix}1 & 0& 1&7\\ 0 & 1 & 0& -1 \\0&0&1&3 \end{bmatrix}[/tex]
And finally, we can eliminate the second 1 by adding -(R₃):
[tex]\begin{bmatrix}1 +(0)& 0+(0)& 1+(-1)&7+(-3)\\ 0 & 1 & 0& -1 \\0&0&1&3 \end{bmatrix}\\\Rightarrow\begin{bmatrix}1 & 0& 0&4\\ 0 & 1 & 0& -1 \\0&0&1&3 \end{bmatrix}[/tex]
Therefore, our solution set is [tex](4, -1, 3)[/tex]

What is 5^8 plus 9375?
Answer:
400000
Step-by-step explanation:
5^8 = 390625
390625 + 9375 = 400000
Answer:
400,000
Step-by-step explanation:
We solve for 5^8 first,
this means that 5 is being multiplied by itself 8 times.
5 x 5 x 5 x 5 x 5 x 5 x 5 x 5 = 390,625
Now we add this to 9,375:

A square is cut into two identical rectangles. Find the perimeter of each rectangle if the perimeter of the square is 48 cm.
thankyou ~
Solution:
perimeter of rectangle = 2 ( Length + Width )
a square has all sides of similar length. thus [ length = width ]Find length/width:
2 (length + length) = 48
2(length) = 24
length = 12 cm
width = 12 cm
⇒ The dimensions of square: 12 x 12
If the square cut into half, the dimensions of either length or width will half.
Therefore, the perimeter of rectangle:
→ 2 (length + width)
→ 2 ( 12 + 6 )
→ 2 ( 18 )
→ 36 cm

As we know that the area of an equilateral triangle with side a is given by ;

A grocery store sells sliced turkey. The graph shows the relationship between the weight of the sliced turkey and the total cost of the sliced turkey. Two points, R and W, are labeled on the graph shown below.
Answer:
The correct option is ⇒ Point W means that that unit rate is $2.5 per pound.
Step-by-step explanation:
The question missing the graph and the options
The options for the questions are:
1) Point R means that that unit rate is $10 per pound.
2) Point R means that that unit rate is 4 pounds per dollar
3) Point W means that that unit rate is $2.5 per pound.
4) Point W means that that unit rate is 2.5 pounds per dollar.
And see the attached figure.
As shown in the figure attached
The unit rate will be the total cost per weight
By calculating the unit rate for the graph = (y2-y1)/(x2-x1)
using the given points (4,10) , (1,2.5)
the unit rate = (10-2.5)/(4-1) = 7.5/3 = 2.5
The unit rate means that it will cost $2.5 per pound and this is a gree with the point W which have the same meaning.
So, The correct answer is option 3.

Allie is single, has an adjusted gross income of $25,005 and one exemption of $12400. How much is his tax according to the table? Hint: find taxable income first. $1246 $1263 $1318 $1324
Allie's tax amount is the amount deducted from his taxable income
Allie's tax amount is $1427
How to determine the tax?The given parameters are:
Adjusted gross income = $25,005
Exemption = $12400
Start by calculating the taxable income using
Taxable income = Adjusted gross income - Exemption
So, we have:
Taxable income = $25,005 - $12400
Evaluate the differences
Taxable income = $12605
The question is incomplete.
So, I will use the table of the single taxable income tax bracket and rates, 2016
Using the table, the tax amount on an income of $12605 is:
Tax = $927.50 + 15% * (Amount - $9275)
So, we have:
Tax = $927.50 + 15% * ($12605 - $9275)
Evaluate
Tax = $1427
Hence, Allie's tax amount is $1427
