Use graphing technology to approximate the solutions of the equation. x2 + 5x - 12 = | x + 3| + 7
The solution of the given equations is x=-7 and x=3.
The given equation is x² + 5x - 12 = | x + 3| + 7.
What is the solutions of the equation?A solution is an assignment of values to the unknown variables that makes the equality in the equation true. In other words, a solution is a value or a collection of values such that, when substituted for the unknowns, the equation becomes an equality.
Now, x² + 5x - 12 = | x + 3| + 7 can be rewritten as
x² + 5x - 12 = x + 3 + 7
⇒x² + 5x - 12 = x+10
⇒x² + 5x - 12 -x - 10=0
⇒x² +4x -22 =0
From the obtained graph, the solution of equations is x=-7 and x=3.
Therefore, the solution of the given equations is x=-7 and x=3.

Who is correct and why?
a
Adam is correct because the negative exponent moves the base to the other side of the fraction bar and makes the exponent positive.
b
None of these are correct because the students did not add the exponents in the numerator and then subtract exponents since there is division.
c
Nick is correct because the negative exponent in the numerator moves the whole numerator into the denominator and makes the exponent positive.
d
Shane is correct because all that needs to be done is to make the negative exponents positive.
Answer:the answer is A:nick is correct
Step-by-step explanation:
Based on the fraction given of [tex]\large \frac{2\cdot3^{-4}}{5^{-2}}[/tex], the correct person is c. Nick is correct because the negative exponent in the numerator moves the whole numerator into the denominator and makes the exponent positive.
Why is Nick correct?When a number is being taken to the negative power, then it can be rewritten as a fraction where the number becomes the denominator and the numerator becomes 1.
The number, 2.3⁻⁴ can be written as:

Solve 6^x + 2 = 10 for x using the change of base formula log, y = log y log b
The answer for "x" in 6^(x+2) = 10 is -0.715
The logarithm is the inverse function of exponentiation in mathematics. That is, the logarithm of a given integer x is the exponent to which another set number, the base b, must be increased in order to create x.Firstly, we use the change of base formula. The base must be 6 because the "x" variable is a power of it.6^(x+2) = 10Taking a log with base 6 on both the sidesThen, we can use the property logarithm power rule:(x + 2) log6 = log10(x + 2)(1) = (log10)/(log6)x + 2 = 1/log6x + 2 = 1.285x = 1.285 - 2x = -0.715To learn more about logarithm, visit :

Find the slope of the line passing through the given points. how do you know?
The slope of the line passing through the given points is 0.4 or 2/5.
From the table given below, we have (2, 23) and (5, 24.3).
What is the slope of the line passing through the coordinate points?Use the slope formula to find the slope of a line given the coordinates of two points on the line. The slope formula is m=(y2-y1)/(x2-x1), or the change in the y-values over the change in the x-values.
Put the points (2, 23) and (5, 24.3) in the slope formula and find the slope.
That is, m=(24.3-23)/(5-2)
=1.3/3
=0.4
=4/10 = 2/5
Put m=2/5 and the coordinate points (2, 23) in y=mx+c.
That is, 23=2/5 (2)+c
⇒23 - 4/5 =c
⇒111/5 = c
⇒ c=22.2
Now, equation is y=0.4m+22.2

a simple dart target has two concentric circles. the larger circle has a radius of 4. the smaller circle has a radius of 2. the scoring should correspond to the relative difficulty of hitting the inner circle and the outer ring. how many more points should a player receive for landing a dart in the inner circle, as opposed to the outer ring? the player should receive 2 π times as many points. the player should receive 3 times as many points. the player should receive 9 times as many points. the player should receive 4 π times as many points.

In a survey where the ratio of students who prefer muffins to bagels is 4 to 5 and 420 prefer muffins, 525 students prefer bagels.
Ratio is the relationship between two quantities, normally expressed as the quotient of one divided by the other.
It can be expressed in different ways:
1) Use the ":" to separate the values : a : b
2) Use the word "to" : a to b
3) Write it in fraction: a / b
On the other hand, proportion is the equality of two ratios, such that
a : b = c : d
Given a proportion, the product of its means must be equal to the product of its extremes. That is:
ad = bc
If the ratio of students who prefer muffins to bagels is 4 to 5, and 420 students prefer muffins, the proportion can be written as:
4 : 5 = 420 : n
where n = number of students who prefer bagels

If we share $60 in the ratio 3:1, then each person will get is $45 and $15 respectively
Given,
The total amount = $60
The ratio = 3:1
Then the amount given to first person = 3x
The amount given to the second person = x
Given that the total amount is 60
Then the equation will become
x+3x=60
4x=60
x=[tex]\frac{60}{4}[/tex]

Step-by-step explanation:
once we know what the domain and the range of a function is, this is very simple.
the domain is the interval or set of all valid x (input) values.
the game is the interval or set of all valid y (function result) values.
so, what are all the valid x values ? that means for how many months of collection can we use this function to see how many figurines he has ?
well, we can stay with 0 (what he currently has) and go up to 5 (because after 5 months he does not want to continue this behavior).
so, the domain is
0 <= x <= 5 if we allow also fractions of months as input (if this makes sense)
or
x € {0, 1, 2, 3, 4, 5} if we allow only whole numbers.
and the range ? what are the possible result values of the function ?
for x = 0 it starts with y (or f(x)) = 100.
x = 1 gives us 100 + 3×1 = 103
x = 2 gives us 100 + 3×2 = 106
x = 3, 100 + 3×3 = 109
x = 4, 100 + 3×4 = 112
x = 5, 100 + 3×5 = 115
so, the range is
100 <= y <= 115 if we allow fractions of months
or
y = f(x) € {100, 103, 106, 109, 112, 115} if we allow only whole months as values of x.
the sum of three numbers is 111. the first number is less than the third. the second number is times the third. what are the numbers?
The first, second, and third numbers are 11, 80, and 20 respectively.
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.
Let's say the first number is a second is b and the third one is c
Now,
The sum of the three numbers is 111
So,
a + b + c = 111
The first number is 9 less than the third
So.
a = c - 9
And the second number is 4 times third
So,
b = 4c
By substitution,
c - 9 + 4c + c = 111
c = 20
b = 4(20) = 80
a = 20 - 9 = 11
Hence "The first, second, and third numbers are 11, 80, and 20 respectively".
