Final answer:
The sum of -4 and 3 is -1 because we subtract the smaller number from the larger and keep the sign of the larger absolute value number. The sum of -3 and 5 is positive 2 for the same reason.
Explanation:
The question seems to be asking about the rules for adding numbers with different signs. When adding -4 and 3, which have opposite signs, you subtract the smaller number from the larger number, and the sign of the answer is the same as the sign of the larger absolute value number.
So the sum is -1, because 4 is larger than 3, and the sign is negative. In contrast, when adding -3 and 5, you also subtract the smaller number from the larger, but since 5 is greater than 3, the sum is 2, and it has a positive sign because 5 has a positive sign.
Examples demonstrate the rules of addition:
When two positive numbers are added, like 3 + 2, the result is a positive 5.If two negative numbers are added, for example, -4 + (-2), the result is a negative -6.Mixing a negative and a positive number, such as -5 + 3, the result is -2, mirroring the sign of the larger absolute value number.These basic rules ensure clarity in arithmetic operations and provide a foundation for more complex math problems. The 'complaints' likely refer to the unexpected results when dealing with negative numbers, which can seem counterintuitive but follow consistent mathematical rules.

How many different three digit locker combinations are possible if the digits are able to repeat?
A.30
B.1000
C.300
There are 1000 three digit locker combinations are possible if the digits are able to repeat.
The correct option is B.
If the digits are able to repeat, there are 10 options for each digit (0-9) in a three-digit combination.
Since each digit can be chosen independently, the total number of different three-digit combinations is given by:
Number of combinations
= Number of options for the first digit x Number of options for the second digit x Number of options for the third digit
Number of combinations = 10 x 10 x 10 = 1000

Coach Stevens needs to purchase sprinklers to water the baseball field. The standard distance between bases is 90 feet and the infield is a perfect square.
Coach Stevens found one sprinkler that sprays a maximum distance of 50 feet.
If Coach Stevens placed the sprinkler on the pitcher's mound, would the water spray so that the entire infield was watered? Justify your response.
Answer:
So, if coach Stevens places as sprinkler of maximum distance 50 ft, he won't be able to cover the entire infield.
Step-by-step explanation:
Consider the infield as a polygon ABCDE.
It is given that each side AB, BC, CD, and DA is of length 90ft. It is also given that the infield is a perfect square.
Thus, the area of the square ABCD = 8100 ft.
Now consider the triangle BCD. Because of symmetry, the area of this triangle equals half the area of the square. Again, because of symmetry, the length of the base BD equals twice the length of the height EC.
Thus from to the formula of area of the triangle:
base × height = 4050 base × height = 8100 2(height) × height= 8100 height63.64 ft

Write in slope-intercept form of the equation of the line through the given point. Through: (-3,-3) and (4,0)
Answer:
y = 3/7 x - 12/7
Step-by-step explanation:
The slope is (0+3)/(4+3) = 3/7
So, now you have a point and a slope, so use the point-slope form. That gives you
y-0 = 3/7 (x-4)
Now just rearrange to slope-intercept form.
y = 3/7 x - 12/7

in a 30-60-90 Blondie triangle the long leg is half the hypotenuse
A. always
B. sometimes
c never
Answer:
never
Step-by-step explanation:
In a 30 - 60 - 90 degree triangle , the common ratio is
1 : [tex]\sqrt{3}[/tex] : 2
Shorter leg that is opposite to 30 degree = 1
Longer leg that is opposite to 60 degree = [tex]\sqrt{3}[/tex]
Hypotenuse is opposite to 90 degree = 2
Shorter leg is half the length of the hypotenuse as per the ratio
Long leg is never the half of the hypotenuse

State how many imaginary and real zeros the function has. f(x) = x3 + 5x2 - 28x - 32
All equation has always
even numbers of imaginary roots because they always come in pairs. Therefore
there must be either 2 imaginary roots, or zero.
To determine the types of roots, we could try synthetic
division by some of the factors of the number -32. The simplest factors are +1
or -1. Using this, we can quickly show that (x + 1) is a factor, and leaving
(x² + 4x - 32) as the remainder. This remainder equation then factorises to (x
- 4) (x + 8).
So to conclude there are three real zeros which are:
x = -1
x = 4
x = -8
Which exponential function goes through the points (1, 8) and (4, 512)?
f(x) = 4(2)^x
f(x) = 8(2)^-x
f(x) = 4(4)^-x
f(x) = 2(4)^x
Answer:
Therefore, the correct option is: (C.) [tex]\( f(x) = 2 \cdot 4^x \)[/tex]
Explanation:
To determine the exponential function that passes through the given points, we can use the general form of an exponential function:
[tex]\[ f(x) = a \cdot b^x \][/tex]
Where:
[tex]\( a \)[/tex] is the initial value or the value of the function when [tex]\( x = 0 \).[/tex]
[tex]\( b \)[/tex] is the base of the exponential function.
Given the points [tex]\((1, 8)\) and \((4, 512)\)[/tex], we can substitute these coordinates into the general form and solve for [tex]\( a \) and \( b \).[/tex]
Using the point [tex]\((1, 8)\):[/tex]
[tex]\[ 8 = a \cdot b^1 \][/tex]
[tex]\[ 8 = a \cdot b \][/tex]
Using the point [tex]\((4, 512)\):[/tex]
[tex]\[ 512 = a \cdot b^4 \][/tex]
We can divide the equation obtained from the second point by the equation obtained from the first point to eliminate [tex]\( a \)[/tex] and solve for [tex]\( b \):[/tex]
[tex]\[ \frac{512}{8} = \frac{a \cdot b^4}{a \cdot b} \][/tex]
[tex]\[ 64 = b^3 \][/tex]
Taking the cube root of both sides:
[tex]\[ b = 4 \][/tex]
Now that we have found the value of [tex]\( b \)[/tex], we can substitute it back into one of the equations to find \( a \). Let's use the first point [tex]\((1, 8)\):[/tex]
[tex]\[ 8 = a \cdot 4 \][/tex]
[tex]\[ a = 2 \][/tex]
So, the exponential function that passes through the points [tex]\((1, 8)\) and \((4, 512)\)[/tex] is:
[tex]\[ f(x) = 2 \cdot 4^x \][/tex]

How do you Solve by factoring
Final answer:
To solve an equation by factoring, find the factors, set them equal to zero, and solve for the variable.
Explanation:
To solve an equation by factoring, you need to find the factors of the equation and set each factor equal to zero. Then, solve each equation separately to find the values of the unknown variable. Let's take an example:
If we have the equation [tex]x^2 - 5x + 6 = 0[/tex]:
Factor the quadratic expression: (x - 2)(x - 3) = 0Set each factor equal to zero and solve: x - 2 = 0 and x - 3 = 0solve each equation separately to find the values of x: x = 2 and x = 3This method of factoring and setting each factor equal to zero is a systematic approach to solving quadratic equations, providing a structured way to identify the solutions for the unknown variable. The application of this technique is fundamental in algebra, enabling the efficient determination of roots in quadratic expressions and contributing to a comprehensive understanding of solving equations.
