21. --x-5 = y; (9,-11)
3
answer is y=x+216 and -6.
In the question, the expression is given 221--x-5=y;(9-11)3
An equation is said to be linear equation in two variables if it is in the form of ax + by + c=0, where a, b & c are real numbers and a and b respectively, are not equal to zero. For example, 10x+4y = 3 and -x+5y = 2 are linear equations in two variables.
Unique Solution:
For the given linear equations in two variables, the solution will be unique , if and only if they intersect at a point.
No Solution:
For the given linear equations in two variables, the given system of equations has no solution if lines of two linear equations are parallel.
Infinitely many solution:
For the given linear equations in two variables, the given system of equations has infinitely many solution if lines of two linear equations coincident.
Two consecutive minus signs have the same mathematical meaning as a single plus sign .
221+x-5=y,(9-11).3
x+216=y
Subtract 216 from both sides of the equation,
x+216-216=y-216
x=y-216
replace x with y-216 in the expression
(9-11).3
subtract 11 from 9
-2.3
Multiply -2 by 3
-6
Hence, Final answer is y=x+216 and -6.

What is (f⁰g)(-3) for the functions f and g defined in Problem 3 ?
f(g(-3)) = f(6) = 9.
For composing functions like this, we'll work from the inside out. First, find g(-3) by plugging x = -3 into the function g(x):
g(x) = |x - 3|
g(-3) = |-3 - 3|
g(-3) = |-6|
g(-3) = 6
Now we can replace g(-3) with 6 in the function composition to get f(g(-3)) = f(6). Find f(6) by plugging x = 6 into the function f(x):
f(x) = x + 3
f(6) = 6 + 3
f(6) = 9
So, f(g(-3)) = f(6) = 9.

In 1992, the moose population in a park was measured to be 3590. by 1999, the population was measured again to be 4500. if the population continues to change linearly p(t)= ____ b.) what does your model predict the moose population to be in 2006?
population at 1992 = 3590
Population after Seven years (1999) = 4500
Given two points (t1, P1) and (t2, P2), the slope of the line m can be found.
p1 = (1992, 3590) and p2 = (1999, 4500)
m= ΔP/Δt
m= ((4500-3590))/((1999-1992))
m = 910/7
m=130 is the slope
The linear population function P(t) is
P(t)=130t + P0
Find the Y-Intercept P0
The population function P(t) is measured since the year 1990, year zero. The first moose population was measured in 1992, one year later. This provides an initial condition P (1) = 4500.
P (1) =130 (1) + P0 = 4500
P0 = 4370
P(t)=20t+4630
The moose population P(t) changes linearly year after year. The population function P(t) is measured in terms of t years since 1990.
t= 1990, P (0) =4370
t =1992, P (1) =130 (1) + 4370 = 4500 matches data
t=1999, P (2) = 130(2) + 4370 = 4630

Domain of inverse of f(x)=√x -1 is [-1,∞),{x|x≥-1}
Range of inverse of f(x)=√x -1 is [0,∞),{y|y≥0}
Finding the Inverse Function but not the Inverse Function's Domain and Range
First, we must determine the domain and range of the original function f in order to determine the domain and range of an inverse function (x).
1.Find the function's domain and range.
Assume that the domain of the function f(x) is [0,∞),{x|x≥0}
Assume that the range of the function f(x) is [-1,∞),{y|y≥-1}
2. Substitute Domain for Range and Range for Domain
The domain of the calulated function f^-1(x) is [-1,∞),{x|x≥-1}
f^-1(x) calculated function (x) the interval for range is [0,∞),{y|y≥0}
∴Domain of inverse of f(x)=√x -1 is [-1,∞),{x|x≥-1}

log 2 x+log x=11
log 2x + log x = 11 => x = 223600, by properties of logarithm.
What is Logarithm?The opposite of exponentiation is the logarithm.This indicates that the exponent to which a fixed number, base b, must be raised in order to obtain a specific number x, is represented by the logarithm of that number.A number's natural logarithm is its logarithm to the base of the transcendental and irrational number e, which is roughly equivalent to 2.718281828459.Now,
log (2x) + log (x) = 11
=> log [(2x)(x)] = 11 (as log (a) + log (b) = log (ab))
=> log (2x²) = 11
Since, generally the base of log is 10, raising them to 10
=> [tex]10^{log_{10}(2x^{2})} = 10^{11}[/tex]
=> 2x² = 10¹¹
=> x² = [tex]\frac{10^{11}}{2}[/tex]
=> x = [tex]10^{5}\sqrt{\frac{10}{2}} = 10^{5}\sqrt5[/tex]
=> x = 10⁵ (2.2360)
=> x = 223600
Hence, log 2x + log x = 11 => x = 223600, by properties of logarithm.

Which line has an equation of y = negative 5 x + 4 in slope-intercept form?
The correct option is (d).
d) (2,-6) & (4,-16)
Now, To find the correct option that is equivalent to this equation, we can begin by narrowing down the given options.
Since, The slope contains a negative number, that's mean the second point must have a lower y value than the first x value.
Hence, By using this criteria, we can eliminate the first and the third option.
Now, we can check the second and fourth option as;
We can test using by putting in values.
Let's plug in the point values to check whether they work:
Hence, For option 2:
y = -5x + 4
-24 = -5(4) + 4
-24 = -20 + 4
-24 ≠ -16
And, For option 4:
y = -5x + 4
-16 = -5(4) + 4
-16 = -20 + 4
-16 = -16
Therefore, The correct option is option (d).

1. At the ice cream shop, there are 14 shakes
sold for every 6 malts. Record the ratios
below.
b. malts to total
The ratio of malts to the total ice creams is 3:10 .
Ratio is defined as the fraction which defines the relationship between two quantities .
Ratio is denoted by a:b such that it can also be written as a/b where a and b are co-prime. Ratio can also be denoted as a decimal but mostly it is represented as fraction in its lowest terms
Now the given ice cream shop has 14 shakes that are sold for every 6 malts.
Hence when 14 shakes are sold total number of ice cream sold is
14+6 = 20 .
Now we have to find the ratio of the malts to the total number of ice creams
∴ malts : ice creams = 6 : 20
Reducing to lowest terms we get :
ratio = 3:10
Hence the ratio of malts to total ice cream is 3:10
