What multiplies to 16 and adds to negative 12

Answers

factor 16 and see the - factor pairs and add them, see which add to -12
-1-16=-17 nope
-2-8=-10 nope
-4-4=-8
hmm


we will solve with math
xy=16
x+y=-12
minus  x both sides
y=-12-x
sub for y in other equation
x(-12-x)=16
-12x-x^2=16
add 12x+x^2 both sides
0=x^2+12x+16
use quadratic formula
if you have
ax^2+bx+c=0
x=\frac{-b+/- \sqrt{b^(2)-4ac} }{2a}


0=x^2+12x+16
a=1
b=12
c=16

x=\frac{-12+/- \sqrt{12^(2)-4(1)(16) }}{2(1)}
x=(-12+/- √(144-64 ))/(2)
x=(-12+/- √(80))/(2)
x=(-12+/- 4√(5))/(2)
x=\frac{-6+/- 2√(5)
x=\frac{-6+ 2√(5) or \frac{-6- 2√(5)

aprox
x=-1.52786 or -10.4721

The function g(x) = –3x2 – 36x – 60 written in vertex form is g(x) = –3(x + 6)2 + 48. Which is one of the transformations applied to the graph of f(x) = x2 to change it into the graph of g(x) = –3x2 – 36x – 60? The graph of f(x) = x2 is made narrower. The graph of f(x) = x2 is shifted right 6 units. The graph of f(x) = x2 is shifted down 48 units. The graph of f(x) = x2 is reflected over the y-axis.

Answers

The general vertex form is this:
v(x) = a (x-h)2 + k
where (h,k) is the coordinates of the of vertex.
and a indicates the widening or shrinking of the function compared to another parabolic function. If a become bigger, the graph becomes narrower. If a becomes negative, the graph is reflected over the x-axis.

Comparing f(x) = x2 with g(x) = -3(x+6)2 + 48, we have the following transformations:
The graph is reflected over the x-axis
The graph is made narrower.
The graph is shifted 6 units to the left.
The graph is shifted 48 units up.

From the choices we only have:
The graph of f(x) = x2 is made narrower

A. The graph of f(x) = x2 is made narrower.

A Gallup survey showed that in March 2011, 8 of every 25 employers in the United States were adding more workers to their workforce, 9 of 50 were reducing their workforce, and 1 of 2 were keeping it the same. If there were 1250 employers in one metropolitan area, and those who were hiring planned to hire an average of 7 new employees, how many new jobs were about to become available?

Answers

Final answer:

By applying the provided ratio of hiring employers to the total number of employers, and then multiplying by the average number of new hires per employer, we can conclude that an estimated 2800 new jobs were about to become available in this metropolitan area.

Explanation:

To solve this problem, we must note that 8 in 25 employers were planning to add more employees. This is a ratio of 8/25. With a total of 1250 employers in the area, we can calculate the number of employers that are hiring by multiplying this ratio by the total number of employers: (8/25)*1250 = 400 employers. Each of these employers was set to hire an average of 7 new employees, so we multiply the number of employers hiring by the average number of new hires: 7 new employees * 400 employers = 2800 new jobs. Thus, 2800 new jobs were about to become available in this area.

If you decide to divide a pie that has a diameter of 8 inches into 6 equal slices, what is the area of each slice?A) 8.37in^2
B) 4.19in^2
C) 33.49in^2
D) 50.24in^2

Answers

the answer to this problem is C. please let me know later if you confirm this answer is indeed correct. The area of a circle is Area= \pi * r^(2). Therefore, the area of the whole pie is 64\pi. The answer will be: (Areaof whole pie)/(6), which is roughly equal to 33.

Order the numbers from least to greatest.-0.5, 3, -3, 1.2
The order of the numbers from least to greatest is (blank)

Answers

The order of the numbers from least to greatest is -3, -0.5, 1.2, 3.

How do we order the numbers from least to greatest?

For us to order the numbers from least to greatest, we first have to arrange the numbers in ascending order based on their values as follows -3, -0.5, 1.2, and 3.

Step 1: Compare -3 with the other numbers because -3 is the smallest, it comes first.

Step 2: We compare -0.5 with the remaining numbers.

Step 3: We evaluate 1.2 in comparison to the remaining numbers.

Step 4: 3, being the largest among the provided values is positioned at the end of the sequence.

Hence, the order of the numbers from least to greatest is -3, -0.5, 1.2, 3.

The depth of the submarine is 50 ft below sea level when it starts to descend at a rate of 10.5 ft/s. It dives at that rate for 5 s. What are the constraints on the x- and y-values?

Answers

The x represents time in seconds while y represents the depth of the submarine and the equation with constraint will be y = 10.5x + 50.

How to form an equation?

Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.

In other words, an equation is a set of variables that are constrained through a situation or case.

As per the given,

The slope m = rate of descending = 10.5 ft/s

The y-intercept c = initial depth of submarine = 50 ft

Thus, y = mx + c converts as,

y = 10.5x + 50

Hence "The x represents time in seconds while y represents the depth of the submarine and the equation with constraint will be y = 10.5x + 50".

Answer:

The constraints on the x-values or independent variable – time are:

0 s < time < 5 s

The constraints on the y-values or dependent variable – Depth are:

50 ft < Depth (below sea level) < 102.5 ft

Step-by-step explanation:

Boundary restrictions that are placed upon the variables in an equation are called the Constraints.

The x-values are the independent variables in an equation and in our case it is time.

The y-values are the dependent variables in an equation and in our case it is depth (below the sea level).

The rate of descend provided in the question is constant and is equal to 10.5 ft/s.

We can write our equation of Depth as follows:

Depth (below sea level) = 50 + 10.5*(time)

The constraints on the x-values or independent variable – time are:

0 s < time < 5 s

We can put the boundary values of x variable constraints in the equation of Depth to find the constraint on y-values or dependent variable.

Depth (below sea level) = 50 + 10.5*(time)

Depth (below sea level) = 50 + 10.5*(0), at time 0 s

Depth (below sea level) = 50 ft

Depth (below sea level) = 50 + 10.5*(5), at time 5 s

Depth (below sea level) = 102.5 ft

So the constraints on the y-values or dependent variable – Depth are:

50 ft < Depth (below sea level) < 102.5 ft
