what two numbers add to "-5" and multiply to "-4"
The numbers that add to -5 and multiply to -4 are -5.7015 and 0.7015.
There are two numbers. The addition of the two numbers is -5. The multiplication of the two numbers is -4. We need to find the two numbers. Let the first number and the second number be represented by the variables x and y, respectively. Then, we can write the two following equations.
x + y = -5
x*y = -4
We will substitute the value of y from the first equation into the second equation.
x*(-5 - x) = -4
x*(x + 5) = 4
x² + 5x - 4 = 0
Now, we will use the quadratic formula.
x = [-5 ± √(5² - 4(1)(-4))]/2(1)
x = [-5 ± √(25 + 16)]/2
x = [-5 ± √41]/2
x = [-5 ± 6.403]/2
The values of x are -5.7015 and 0.7015. The corresponding values of y are 0.7015 and -5.705.

The mean, median and mode of the numbers below are the same,
what is the value of a?
6, 2, a, 7, 4, 9,6
Answer:
8
Step-by-step explanation:
Put the numbers in order from lowest to highest. Add all the numbers together. We will ignore a for this step. You should get 34 when adding it all together. Then if you were to add 8 to that 34 you'd get 42. Divide 42 by the amount of numbers you have which is 7. Your answer is 6. Now to make sure 8 is our value. We want to make sure the median is also 6. to find the median you need to have the numbers in order for lowest to highest and find the number in the middle. Don't forget to add your new number 8 into that order. You should get 6 as the median. Therefore our answer is 8

A mathematical expression that includes variables, constants, and algebraic operations is known as an algebraic expression (addition, subtraction, etc.). Terms comprise expressions.
There are three primary categories of algebraic expressions, including:
Monomial expression
Binomial expression
Polynomial expression
An algebraic expression can be divided into two additional types in addition to the monomial, binomial, and polynomial types. These are:
Numeric Expression
Variable Expression
Numeric expression - A numeric expression consists of numbers and operations, but never include any variable.
Variable expression - A variable expression is an expression that contains variables along with numbers and operation to define an expression.

B) The missing angle at the intersection point of both triangles is; x = 15°
C) The missing angle is gotten as; x = 61°
How to find the missing angles?B) In the second image given, we can see two angles;
Now, we know that sum of angles in a triangle is 180 degrees. Thus, for the interior angles, we have;
90 + 5x - 14 + y = 180
where y is the third interior angle
Now, we know that sum of angles on a straight line is equal to 180 degrees. Thus;
y = 180 - (9x + 16)
Put 180 - (9x + 16) for y into the first equation to get;
90 + 5x - 14 + 180 - (9x + 16) = 180
180 will cancel out to get;
90 + 5x - 14 - (9x + 16) = 0
4x = 90 - 14 - 16
4x = 60
x = 60/4
x = 15°
C) The missing angle of the triangle with side of 12y + 3 is an alternate angle to get;
Missing angle = 63°
Sum of angles in a triangle is 180 degrees. Thus;
56 + 63 + 3rd angle = 180
3rd angle = 180 - (56 + 63)
3rd angle = 61°
Thus, x = 61° because they are opposite angles
Also, the two given sides are equal to each other as shown. Thus;
51 = 12y + 3
12y = 51 - 3
12y = 48
y = 48/12
y = 4

How do you find the distance between the points shown? (C: 6, -4) and (D: 6, -8)
A. Subtract the distance between each point and the x-axis
B. Add the distance between each point and the x-axis
C. Subtract the distance between each point and the y-axis
D. Add the distance between each point and the y-axis
Answer:
A. Subtract the distance between each point and the x-axis.
Step-by-step explanation:
As the two points have the same x-coordinate, x = 6, it means they lie on the vertical line x = 6.
Therefore, the distance between the points can be found by subtracting the distance between each point and the x-axis.
In the given example, the points are C(6, -4) and D(6, -8).
To find the distance between a point and the x-axis, we simply take the absolute value of the y-coordinate of the point:
Distance between point C and the x-axis = |-4| = 4
Distance between point D and the x-axis = |-8| = 8
Subtracting the distances, we get:
Distance = 8 - 4
Distance = 4
Therefore, the distance between points C and D is 4 units.
a store increased the original price of a shirt by a certain percent and then decreased the new price by the same amount. given that the resulting price was 84% of the original price, by what percent was the price increased and decreased?
A retailer raised a shirt's original price by a certain percentage before lowering it by the same percentage. The price was increased and decreased by 40% as the final cost was 84% of the initial cost.
What is percent?In essence, percentages are fractions with a 100 as the denominator. We place the percent symbol (%) next to the number to indicate that the number is a percentage. For instance, you would have received a 75% grade if you answered 75 out of 100 questions correctly on a test (75/100). A number or ratio that can be expressed as a fraction of 100 is referred to as a percentage in mathematics. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The percentage therefore refers to a part per hundred. Per 100 is what the word percent means. The letter "%" stands for it.
Here,
Let's say the shirt originally cost Rs 100, and we're adding t% to the price.
The new price of the shirt is therefore 100 + (t/100 * 100) = Rs. 100+t after the initial t% increase.
The price is then reduced by t%.
Cost of a new shirt: (100 + t) - (t/100)
[100+t] = (100+t)
[1-(t/100] = [(100+t)/100]
therefore, the final price is equal to 84% of Rs 100, or Rs 84.
10000 - t^2 = 84.
t^2 = 1600
t = 40
The price was thus raised and lowered by 40%.
The original price of a shirt was increased by a specific percentage before being decreased by the same percentage by the retailer. As the final price was 84% of the initial price, the price was both increased and decreased by 40%.

Marcus is accurate. Jeremy is wrong because he overlooked the negative sign in the equation's initial addend. Since -25 has a greater absolute value than 3, it is obvious that the sum should be negative.
Marcus is correct; the solution is -22.
The simplified expression is given as:

The right response is this. Marcus saw the bracket or parentheses symbol when he condensed his sentence. This has major significance.
Jeremy scored 28. He squared -5 without noting that it was in a bracket or parenthesis, therefore his response is incorrect.
