Becky bought 6 dried apples and 4 dried apricots if Becky bought seven more packages of dried apples than dried apricots. If she bought fifteen of these two fruits altogether.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
It is given that:
Becky bought seven more packages of dried apples than dried apricots.
Let x be the number of dried apples
Let y be the number of dried apricots
x = y + 7
She bought fifteen of these two fruits all together
x + y = 15
The above two equation represents the linear equation in two variables, solving the linear equation in two variables by the substitution method:
y + 7 + y = 15
2y = 15 - 7
2y = 8
y = 8/2
y = 4
x = 4 + 2 = 6
Thus, Becky bought 6 dried apples and 4 dried apricots if Becky bought seven more packages of dried apples than dried apricots. If she bought fifteen of these two fruits altogether.

Loretta invested $1000 in a simple interest account yielding 5% paid annually. In 2 years, she will have $1100 in her account. From this example, we can conclude that 5% represents the:
Final answer:
The 5% represents the annual interest rate on Loretta's investment in a simple interest account.
Explanation:
The 5% represents the annual interest rate on Loretta's investment. In simple interest, the interest is calculated as a percentage of the initial investment. So, if Loretta invested $1000, and after 2 years her account has grown to $1100, the interest earned would be $100 (1100 - 1000).
To find the interest rate, we can use the formula:
Interest = Principal * Rate * Time
Using the given information, we can plug in the values and solve for the rate:
100 = 1000 * Rate * 2
Simplifying the equation, we get:
Rate = 100 / (1000 * 2) = 0.05 or 5%
Therefore, the 5% represents the annual interest rate in this scenario.

Answer:
After 4 hours, there will 91.31 miligrams of caffeine within his body.Step-by-step explanation:
Givens
Curt drank 130 miligrams of caffeine.His body processes 7% of caffeine everyhour.If Curt's body processes 7% every hour, we just need to that 7% after each hour. Also, we know that 7% equals 0.07.
First hour.
[tex]0.07(130)=9.1ml[/tex]
The first hour, his body processed 9.1 miligrams, so it remains
[tex]130-9.1=120.9ml[/tex]
There's still 120.9 miligrams in his body.
Second hour.
[tex]0.07(120.9)=8.46ml[/tex]
[tex]120.9-8.46=112.44ml[/tex]
Third hour.
[tex]0.07(112.44)=7.87ml[/tex]
[tex]112.44-7.81=104.63ml[/tex]
Fourth hout.
[tex]0.07(104.63)=7.32ml[/tex]
[tex]104.63-7.32=97.31ml[/tex]
Therefore, after 4 hours, there will 91.31 miligrams of caffeine within his body.

A segment has an endpoint (14,-8) and (4,12) what are the coordinates of its midpoint
The coordinates of the midpoint of the segment that has endpoints as (14,-8) and (4,12) are (9,2).
What are the coordinates of the midpoint of the line segment AB?Midpoint, as the word suggests, means the point which lies in the middle of something. The midpoint of a line segment means a point which lies in the mid of the given line segment.
Suppose we've two endpoints of a line segment:
A(p,q), and B(m,n)
Then let the midpoint be M(x,y) on that line segment. Then, its coordinates are:
x = (p+m) / 2
and
y = (q+n) / 2
Given that a segment has an endpoint (14,-8) and (4,12). Therefore, The coordinates of the midpoint of the segment can be written as,
X- coordinate = (14+ 4)/2
= 18/2
= 9
Y- coordinate = (-8+12)/2
= 4/2
= 2
Hence, the coordinate of the midpoint of the segment that has endpoints as (14,-8) and (4,12) is (9,2).

Analyze the function’s graph to determine which statement is true.
Over the interval [–2.5, 0.5], the local maximum is 2.
As the x-values go to positive infinity, the function’s values go to negative infinity. The function is decreasing over the interval (–1, 0.75).
The function is negative for the interval [–2, 0]
The truth of the statements in the question can be verified by analyzing the function's graph over the stipulated intervals. Understanding concepts such as local maxima, the behavior of functions at infinity, an interval of decrease, and intervals where a function remains negative or positive are essential in this process.
Explanation:To determine which statement in the question is true, we need to analyze the function's graph. The statements included talk about specific behaviors of the function in different intervals of the x-axis.
The first statement mentions a local maximum of 2 over the interval [–2.5, 0.5]. You will need to locate this interval on the x-axis and see if 2 is indeed the highest y-value within this range. If there is a point on the function where the y-value is 2 and it is higher than all neighboring points, then this statement is true.
The second statement states that as the x-values go to positive infinity, the function's values go to negative infinity. This implies that as the function continues towards the positive direction on the x-axis, the y-values continuously decrease towards negative infinity. If the graph shows this, then this statement is true.
The third statement says the function is decreasing over the interval (–1, 0.75). This would mean that as x goes from –1 to 0.75, the y-values decrease. If you observe this on the graph, this statement is true.
The last statement asserts the function is negative for the interval [–2, 0]. If, for all x-values from –2 to 0, the corresponding y-values are below the x-axis (negative), then this statement is valid.

The youngest age Jorge's brother can be is 13. This is derived from the given condition that the sum of their ages is no less than 25, by assigning Jorge's brother's age as an unknown 'x' and using algebraic principles.
Explanation:The subject question is a simple algebraic problem. Let's denote Jorge's brother's age as x, so Jorge's age would be x-1. The problem states that the sum of their ages is no less than 25, which would translate algebraically into x + (x-1) ≥ 25.
Then we simplify the equation by combining like terms, it turns into 2x - 1 ≥ 25. To isolate x, you first add 1 to both sides of the equation, which gives you 2x ≥ 26, and then divide both sides by 2, resulting in x ≥ 13.
Therefore, the youngest age Jorge's brother can be is 13.

Need Answer ASAP!!!!!!!Solve the equation using the zero product property. -n(5n-4)=0
Answer:
[tex]n=0\text{ or }n=\frac{4}{5}[/tex]
Step-by-step explanation:
We have been given an equation [tex]-n(5n-4)=0[/tex]. We are asked to solve our given equation using zero product property.
Zero product property states that the product of two expressions are zero, if and only if, one of them is zero.
Using zero product property, we will set each factor of our equation to zero as:
[tex]-n=0\text{ or }(5n-4)=0[/tex]
[tex]n=0\text{ or }5n-4=0[/tex]
[tex]n=0\text{ or }5n-4+4=0+4[/tex]
[tex]n=0\text{ or }5n=4[/tex]
[tex]n=0\text{ or }\frac{5n}{5}=\frac{4}{5}[/tex]
[tex]n=0\text{ or }n=\frac{4}{5}[/tex]
Therefore, the solutions for our given equation are [tex]n=0\text{ or }n=\frac{4}{5}[/tex].

Dustin has only nickels and quarters in his piggy bank. He has 49 coins total for a combined value of $8.85. How many of each does he have
Answer:
Dustin has 17 nickels and 32 quarters.
Explanation:
Let's denote the number of nickels as [tex]\(n\)[/tex] and the number of quarters as [tex]\(q\).[/tex]
We can set up a system of equations based on the given information:
1. The total number of coins: [tex]\(n + q = 49\)[/tex]
2. The total value of the coins: [tex]\(0.05n + 0.25q = 8.85\)[/tex]
We can solve this system of equations to find the values of [tex]\(n\) and \(q\).[/tex]
From equation (1), we can express [tex]\(n\)[/tex] in terms of [tex]\(q\):[/tex]
[tex]\[n = 49 - q\][/tex]
Now, substitute this expression for [tex]\(n\)[/tex] into equation (2):
[tex]\[0.05(49 - q) + 0.25q = 8.85\][/tex]
[tex]\[2.45 - 0.05q + 0.25q = 8.85\][/tex]
Combine like terms:
[tex]\[0.20q + 2.45 = 8.85\][/tex]
Subtract 2.45 from both sides:
[tex]\[0.20q = 6.40\][/tex]
Now, divide both sides by 0.20:
[tex]\[q = \frac{6.40}{0.20} = 32\][/tex]
So, Dustin has 32 quarters.
To find the number of nickels, we can substitute the value of \(q\) into the equation [tex]\(n + q = 49\):[/tex]
[tex]\[n + 32 = 49\][/tex]
[tex]\[n = 49 - 32\][/tex]
[tex]\[n = 17\][/tex]
So, Dustin has 17 nickels.
