The answer to the expression -( 7 4x )= 9 is -7, since subtracting 7 from both sides of the equation leaves us with 4x = 2, and then dividing both sides of the equation by 4 gives us x = -7.
The expression -( 7 4x ) = 9 can be solved by using basic algebraic operations. First, we subtract 7 from both sides of the equation to obtain -4x = 2. This is because when subtracting a number from both sides of an equation, we are essentially adding the opposite of that number to both sides. Then, we divide both sides of the equation by 4 to obtain x = -7. This is because when dividing both sides of the equation by a number, we are essentially multiplying both sides by the inverse of that number. Therefore, the answer to the expression is -7.
-(7 4x ) = 9
-7 - 4x = 9
-4x = 2
x = -7

Hana i planning a park day for the next month to give her friend ome exercie! The local park open it path for biker every 12 day and open it’ lake for paddling every 8 day. Today, both the biking and paddling option are open. Which two number entence will help Hana pick the next date where both the bike lane and lake padding will be open?
If a local park is open for biking every 12 day open for paddling every 8 day and if today the park is open for both options, then the next date when the park will be open will be on the 24th day. So Hana should pick 24th day from today next.
Every 12 day the local park is open its path for biking and every 8 day they open their lake or paddling. That is in every multiple of 12 days the biking option is available and every multiple of 8 days the paddling option is available.
If today both the biking and paddling option are open, then the next day where both options will be open can be determined by calculating the least common multiple of 12 and 8.
12 = 2×2×3
8 = 2×2×2
LCM (12, 8) = 2×2×2×3
LCM(12, 8) = 24
LCM of 12 and 8 is 24. So 24 days from today, the park will be open for both options.

How do you find the square root of a number without a calculator?
Without using a calculator, the square root of an integer is
1. Use multiplication to calculate the ideal square root.
2. Use division to calculate the ideal square root.
3. Use nearest perfect square number to find the square root of non-perfect squared numbers.
Given that,
We need to figure out how to calculate a number's square root without a calculator.
We know that,
There are some ways to find
First
Use multiplication to calculate the ideal square root.
A number that, when multiplied by itself, equals the first number is the number's square root.
3 is therefore the square root of 9.
Because 3 multiply by 3 is 9
That is 3×3=9
√9=3
Second
To calculate the square root, we use division.
A whole number can also be divided by a number until you get an answer that is the same as the number you used to divide the whole number in order to determine its square root.
For instance: Four is the square root of sixteen.
Because 16 divided by 4 is 4
That is 16÷4=4
√16=4
Third
We must compare the number with a nearly perfect squared number in order to determine the square root of non-perfect squared numbers.
For example: the square root of 63 is not a perfect square.
So,
The closest perfect square integer right now is 64, and its square root value is 8.
So, we can say the square root of 63 as 7.98.

Can you use SSA to prove a triangle is congruent?
Yes, you can use the Side-Side-Angle (SSA) Congruence Theorem to prove that two triangles are congruent.
The SSA Congruence Theorem states that if two sides of one triangle have the same length as two sides of another triangle, and the included angle in the first triangle is congruent to the included angle in the second triangle, then the two triangles are congruent.
Here is an example of how you can use the SSA Congruence Theorem to prove that two triangles are congruent:
Let's say you have two triangles, triangle ABC and triangle DEF. You are given that the length of side AB is equal to the length of side DE, the length of side AC is equal to the length of side DF, and angle A is congruent to angle D.
To prove that triangle ABC is congruent to triangle DEF, you would need to show that all of the corresponding parts of the triangles are congruent. Since the lengths of two sides (AB and DE) and the included angle (angle A and angle D) are congruent, you can use the SSA Congruence Theorem to conclude that triangle ABC is congruent to triangle DEF.
It's worth noting that the SSA Congruence Theorem is not always sufficient to prove that two triangles are congruent. If the conditions of the theorem are not met, you may need to use other methods, such as the ASA Congruence Theorem or the HL Congruence Theorem, to prove congruence.

A function that is a reflection across the x-axis compared to f(x) would be the mirror image of f(x). It would have the opposite y-values for each x-value. It would also have its vertex at the same place as f(x).
Therefore, it would be a parabola pointing downward, with the points (1, -1), (2,-4), (-1,-1), and (-2,-4).

What is a factor of an equation ?A factor is a number that divides another number, leaving no remainder. In other words, if multiplying two whole numbers gives us a product, then the numbers we are multiplying are factors of the product because they are divisible by the product.

Real roots;-
We are aware that anytime we resolve a linear or quadratic equation, we obtain the equation's value variable, or in other words, we identify the equation's solution. We refer to this "solution" as the real roots. For instance, when we solve the equation x27x+12=0, the real roots come out to be 3 and 4.
Distinct roots;-

Using the terms greater than, larger than or equal to, less than, or less than or equal to as a declaration of the order connection between two integers or algebraic expressions is known as inequality. Economic inequality comes in many forms, most notably wealth inequality measured by the distribution of wealth and income inequality measured by the distribution of income (the amount of money people are paid) (the amount of wealth people own). There are significant forms of economic inequality amongst various groups of people in addition to economic disparity between nations or states.

The Product Rule says that the derivative of a product of two functions is the first function times the derivative of the second function plus the second function times the derivative of the first function.
To obtain the number of strings of 4 decimal digits that have exactly 3 digits that are 9s ; we use the product rule,
In first digit 1 possible way between 0 to 9
In second digit 1 possible way between 0 to 9
In third digit 1 possible way between 0 to 9
In fourth digit 9 possible ways between 0 to 9

What is a slope grade 11?
In grade 11 math, the slope is a concept that is typically introduced in the study of linear equations and graphing.
The slope of a line serves as a gauge for its steepness. It is defined as the change in y (the vertical distance) divided by the change in x (the horizontal distance) between two points on the line.
A line's slope might be zero, positive, negative, or undefinable. A line with a positive slope rises as it goes from left to right, while a line with a negative slope falls as it goes from left to right. A line with a slope of zero is horizontal, while a line with an undefined slope is vertical.
The slope is often represented by the letter m in the equation of a line, which is written in the form y = mx + b. The slope of the line is the coefficient of the x term (the m in the equation).
For example, the slope of the line represented by the equation y = 3x + 4 is 3, while the slope of the line represented by the equation y = -2x + 1 is -2.

The fundamental formula for a triangle's area is A = [tex]\frac{1}{2}*b*h[/tex], which states that the area of a triangle is equal to half the product of its base and height.
To find the height of the yield sign, we need to use the following formula, which is:
