There are 2 pounds of apples Hannah buy for the cost for her purchase to be the same from both stores.

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

At Giant Eagle, a box of cereal costs $2.89 and apples cost $1.29 per pound.

And, At Shop & Save, the apples are $1.05 per pound and a box of

cereal is $3.37.

Now,

Let number of pounds of apples can Hannah buy for the cost for her purchase to be the same from both stores = x

So, We can formulate;

For, At Giant Eagle, a box of cereal costs $2.89 and apples cost $1.29 per pound.

The total cost is,

⇒ $2.89 + $1.29x

And, For Shop & Save, the apples are $1.05 per pound and a box of

cereal is $3.37.

Total cost is,

⇒ $3.37 + $1.05x

Now, We can equate both the equation to find the number of pounds of apple to buy.

⇒ $3.37 + $1.05x = $2.89 + $1.29x

⇒ 3.37 + 1.05x = 2.89 + 1.29x

⇒ 3.37 - 2.89 = 1.29x - 1.05x

⇒ 0.48 = 0.24x

⇒ x = 0.48 / 0.24

⇒ x = 2

The standard form of linear equation is written as ax + by = c, where a, b, and c are real numbers and a and b are not both zero.

In this form, the coefficients a and b are the slopes of the line and c is the y-intercept.

In the equation x = -5, the coefficient of x is 1 and the constant is -5. This equation can be written as 1x + 0y = -5, which is the standard form of the equation.

To solve this equation, we can first subtract 5 from both sides:

1x + 0y - 5 = -5 - 5

1x + 0y = 0

This is the simplest form of the equation and can be used to find the x-intercept of the line. By setting y = 0 and solving for x, we get x = 0. This means that the x-intercept of the line is (0, -5). We can also use this equation to find the slope of the line. The slope of the line is equal to the coefficient of x, which is 1. This means that the slope of the line is 1.

Three equidistant dots on each of two parallel lines (see sketch for illustration purposes only) are joined in all possible ways. The number of triangles that can be formed is 20 triangles

A "Three equidistant dots" refers to three points that are evenly spaced apart on a line. These three points could represent the vertices of a triangle, and in this case, the question is asking how many triangles can be formed by connecting each of the three dots on one line to each of the three dots on a parallel line.

In total, there are 3 dots on one line and 3 dots on the other line, for a total of 6 dots, and the question is asking how many ways the dots can be connected to form triangles.

To find the number of triangles that can be formed, we use the formula for the number of combinations of n things taken 3 at a time, which is n! / (r!(n-r)!). In this case, n = 6 and r = 3.

So, there are 6! / (3! * 3!) = 20 triangles that can be formed.

Answer:

x = 1

Step-by-step explanation:

Since all the fractions have a common denominator of 3, you can multiply both sides by 3 to get rid of the denominator. (Make sure you distribute)

[tex]\frac{7}{3}x+\frac{1}{3}x=1+\frac{5}{3}x[/tex]

[tex]3(\frac{7}{3}x+\frac{1}{3}x)=3(1+\frac{5}{3}x )[/tex]

The maximum number of points of intersection of two distinct circles and a square is 18.

The maximum possible intersection points of a circle and a line is 2. A square comprises 4 line segments, hence, the maximum possible intersection points of a circle and a square is 2 x 4 = 8 points.

The condition for 8-point intersection is that the diameter of the circle must be between s and s√2, where s is the length of the sides of the square, or it can be written as:

          s < d <  s√2

In the problem, there are two circles and a square. Let's denote the circles as C1 and C1, while the square as S

- Maximum number of intersection points of C1 and C2 is 2

- Maximum number of intersection points of C1 and S is 8

- Maximum number of intersection points of C2 and S is 8

Hence, the maximum possible intersection points of these figures is 2 + 8 + 8 = 18 points.

We can set up a system of equations to represent the information given:

What does the term "system of equations" mean?

simultaneous equations, system of equations Two or more equations in algebra must be solved jointly (i.e., the solution must satisfy all the equations in the system). The number of equations must match the number of unknowns for a system to have a singular solution.

x + y = 10 (the total number of bananas and peaches is 10)

0.5x + 1.5y = 9 (the total cost of the bananas and peaches is $9)

To graphically solve this system, we can plot the two equations on the same coordinate plane. The first equation, x + y = 10, represents a line with a slope of -1 and a y-intercept of 10. The second equation, 0.5x + 1.5y = 9, represents a line with a slope of -3 and a y-intercept of 9.

When the two lines intersect, we have the solution to the system of equations. The point of intersection represents the values of x and y that satisfy both equations. We can see that the solution is x=4, y=6. This means that Houa bought 4 bananas and 6 peaches.

To find the value of f(-2) on a graph, you would locate the point (-2, y) on the graph, where y is the value of the function at x = -2. The value of y is the y-coordinate of the point on the graph.

In a cartesian coordinate system, the x-axis and y-axis are perpendicular to each other. The x-axis is the horizontal axis and the y-axis is the vertical axis. When a function is graphed, the x-coordinate is input into the function and the y-coordinate is the output of the function. So, when you are trying to find the value of f(-2) on a graph, you are looking for the y-coordinate of the point where x = -2. To find this point, you would move horizontally along the x-axis until you reach the value of -2. Then, you would move vertically from that point until you reach the point on the graph. The y-coordinate of that point is the value of f(-2)

To translate Geoff's order using Discrete Math,

2 ) Geoff is a truth-teller. Based on his last statement, where ricotta (R) is implied from pepperoni (P) or quail (Q) , we would have no way of knowing if R is true/false if (P or Q) was false- so, R must be true if (P or Q) is false because of the whole “innocent until proven guilty” thing. therefore, since a lie in P or Q would lead to truth, Geoff must be a truth-teller because he can’t tell all lies.

Using this information, that Geoff always tells the truth.

For the third statement, if Geoff is lying then the truth is "I must have pepperoni or quail and I cannot have ricotta cheese."

~[(P ∨ Q) → R] = [(P v Q) ∧ ~R)]

Or in more general terms, ~(a → b) = (a ∧ ~b)

Which, gives us (a → b) = (~a ∨ b)

Anyhow, even if Geoff tells all lies, there is a valid statement that can be made: Pepperoni and sausage, no quail, no ricotta.

The compound interest would be Rs. 35835.51.

What is compound interest?

Compound interest is the interest on a loan or deposit calculated based on both the initial principal and the accumulated interest from previous periods.

To calculate the total amount to be paid after 1.5 years at 15% p.a. compounded half-yearly, the formula is:

A = P(1 + r/n)^(nt)

Where:

A = total amount

P = principal amount (Rs 128000)

r = interest rate (15%)

n = number of times the interest is compounded per year (2 times per year)

t = number of years (1.5 years)

So, the total amount to be paid after 1.5 years would be:

A = 128000 * (1 + 0.15/2)^(2*1.5) = Rs 163835.51

The compound interest can be calculated by subtracting the principal amount from the total amount:

CI = A - P = 163835.51 - 128000 = Rs 35835.51

Hence, the compound interest would be Rs. 35835.51.

Step-by-step explanation:

f(x) = [tex]\sqrt{x}[/tex] + 5

[tex]\sqrt{x}[/tex] + 5  ==> 1/3 * [tex]\sqrt{x}[/tex] + 5  ==> vertical shrink is when the function's y-coordinates shrink from the y-intercept (5 is the y-int) by a factor of 1/3

[tex]\sqrt{x}[/tex]/3 + 5 ==>( [tex]\sqrt{x-3}[/tex])/3 + 5 ==> in order to translate the graph 3 units to the right, subtract x by 3 since x is being affected when the graph moves left/right. In addition, x now has to be 3 units greater in order for the function to have the same value:

[tex]\sqrt{4-3}[/tex] = [tex]\sqrt{1}[/tex]

4 > 1 and 4 = 1 + 3

Hence, g(x) = ([tex]\sqrt{x-3}[/tex])/3 + 5

The slop-intercept form of 2x + y = -2 is y = -2x - 2.

The slope-intercept form of a linear equation is y = mx + b, where m is the slope of the line and b is the y-intercept (the point where the line crosses the y-axis).

To convert the equation 2x + y = -2 into slope-intercept form, we can follow these steps:

1. Isolate y on one side of the equation. We can do this by subtracting 2x from both sides: y = -2x - 2

2. Now we have y = -2x - 2, which is in slope-intercept form.

So, the slope-intercept form of 2x + y = -2 is y = -2x - 2. The slope of the line is -2 and the y-intercept is (-2,0).

Therefore, the slope-intercept form of the equation 2x + y = -2 is y = -2x - 2.
