The numeric value of the function when x = 4 is of: y = 5.
What is the missing information?The graph is not given, but researching the problem on a search engine, it is found that a graph that passes through these following points is given by:
(1,10), (2,8), (3,6), (4,5), (5,2), (6,1).
How to find the numeric value of a function given it's graph?The numeric value of a function is the value of y for the given value of x, hence, we have to look at the value of x on the horizontal axis, and verify the equivalent value of y on the vertical axis.
From the given points in the graph, that we listed in the missing information subsection, we have that the function passes through point(4,5), hence:
The horizontal axis is of x = 4.The vertical axis is of y = 5.Hence:
The numeric value of the function when x = 4 is of: y = 5.

$21,023 is invested, part at 13% and the rest at 11%. If the interest earned from the amount invested at 13% exceeds the interest earned from the amount invested at 11% by $1045.31, how much is invested at each rate?
The amount invested at 11% by $1045.31 and investment rate is -
amount invested at 13%. is $13991
amount invested at 11%. is $7032
Let x represent the amount invested at 13%.
Let y represent the amount invested at 11%.
$21,023 is invested, part at 13 % and the rest at 11%. This means that
x + y = 21023
The formula for determining simple interest is expressed as
I = PRT/100
Where
I represents interest paid on the loan.
P represents the principal or amount taken as loan
R represents interest rate
T represents the duration of the loan in years.
Considering the amount invested at 13%,
P = x
R = 13%
T =1 year
I = (x × 13 × 1)/100 = 0.13x
Considering the amount invested at 11%,
P = y
R =11%
T = 1 year
I = (x × 11 × 1)/100 = 0.11y
If the interest earned from the amount invested at
13% exceeds the interest earned from the amount invested at
5% by $1045.31, it means that
0.13x - 0.11y = 1045.31 - - -- - - - - -1
Substituting x = 21023 - y into equation 1, it becomes
0.13(121023 - y) - 0.11y = 1045.31
y = 7032
x = 21023 - y = 21023-7032
x = 13991
amount invested at 13%. is $13991
amount invested at 11%. is $7032

A nut store normally sells cashews for $4.00 per pound and peanuts for $1.50 per poundBut at the end of the month the peanuts had not sold well, so, in order to sell 60 pounds of peanuts, the manager decided to mix the 60 pounds of peanuts with some cashews and sell the mixture for $2.50 per poundHow many pounds of cashews should be mixed with the peanuts to ensure no change in the revenue? The manager should mix pounds of cashews with the peanuts
In a nut store the required quantity of the cashews in the mix = x / 4 = 3 / 4 pound.
Here,
Cost of 1 pound of cashew = $4.00
Cost of 1 pound of peanut = $1.50
Total cost = 5.50
The average cost of per pound = 5.50 / 2 = 2.75
Now, peanut and cashews mixes,
quantity of the cashews in the mix = x / 4.00
quantity of the peanuts in the mix = x / 1.50
x/4.00 + x/1.50 = 2.75
x = 3
Now,
The required quantity of the cashews in the mix = x / 4 = 3 / 4 pound
and the mix of the peanut in the mix x / 1.50 = 3 / 1.50 = 2 pounds
Thus, The required quantity of the cashews in the mix = x / 4 = 3 / 4 pound

The square of the imaginary number i is -1.
What are imaginary numbers?If you multiply a real number by the imaginary unit I which has the characteristic i2 = -1, you get an imaginary number. The imaginary number bi is squared as -b2. Zero is, by definition, both real and fictional.
A number that results from multiplying a non-zero real number by the iota I is an imaginary number. I in this case Equals (-1) or i2 = -1. Finding the square root of negative integers is made easier by using these values. -4i, 6i, I etc. are some instances of imaginary numbers.

step by step solution for 4(x-3)=0.5x+2
Answer:
x = 4
Step-by-step explanation:
4(x-3) = 0.5x +2
Multiply both sides by 10
40(x-3) + 5x + 20
Simplify (multiply 40 by x-3)
40x - 120 = 5x + 20
Add 120 to both sides
40x = 5x + 140
Subtract 5x from both sides
35x = 140
Divide 35 on both sides
x = 4

Investing for college, Jake originally put $5000 into a savings account that paid 3.5%. There is now $6400 in the account. How long did Jake have the money in the savings account?
Jake put the money in the savings account for about 17.5 years.
Simply explained, a savings account is a place where you can deposit funds and earn interest.
Most people won't pay any tax on their savings interest because it is paid tax-free. Only people with extremely big sums of savings would need to be concerned about this, which is less than 5% of us as basic-rate taxpayers can earn £1,000/year tax-free and higher-rate taxpayers £500.
The interest calculated in a savings account is compound interest:
So let us now calculate the savings rate of interest at 3.5% for the whole time
We know that
[tex]A=P(1+r)^n[/tex]
Where A is the amount , P is the principal , r is the rate and n is the time.
Substituting the values we calculate the value of x.
6400 = 3500 ( 1+0.035 )ⁿ
or, n = 17.54..
So the time required will be about 17.5 years in the savings account.

Given 7(x, y) = (x + 5, y + 4) and the point P (2, 3), what is 7(P)? please show work so sorry
Answer:
(7, 7)
Step-by-step explanation:
We are given the formula 7(x, y) = (x+5, y+4) for a pair of coordinates (x,y).
P is given as the coordinates: (2, 3), therefore if we substitute P into the equation, we can replace x and y in the given equation for the coordinates of P (2,3).
P is given as (2,3), so 7(P) = 7(2,3).
Using the given formula:
7(2,3) = (2+5, 3+4)
2+5 = 7, 3+4 = 7
Therefore 7(P) = (7, 7)
