The system of equations y 2 3x 3 x= -2 has a solution.
What is Equation?A mathematical statement that has a "equal to" symbol between two expressions with equal values is called an equation. as in 3x + 5 Equals 15, for instance.
Equations come in a variety of forms, including linear, quadratic, cubic, etc.
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. We have LHS = RHS (left hand side = right hand side) in every mathematical equation.
To determine the value of an unknown variable that represents an unknown quantity, equations can be solved. The statement is not an equation if there is no "equal to" symbol in it.
According to our question-
y = -2*2/3+3
y= -4/3+3

What is the independent variable in a linear function?; How do the independent and dependent values change in linear functions?; Which function has a constant additive rate of change of?; Which must be true of the data set if a linear function can be used to represent the data?
x is the independent variable in the linear equation ax + by + c = 0
and y is the dependent variable in the linear equation.
Given, an independent variable in a linear function,
we have to define the independent and dependent variables.
Let suppose a linear equation be,
ax + by + c = 0
now, in the above linear equation,
by = -ax - c
y = -(ax + c)/b
So, the value of variable x in the above linear equation, is independent and don't depend on any other variable whereas the value of variable y in the above linear equation, is dependent as it depends on the value of the variable x.
Therefore, x is the independent variable in the linear equation and y is the dependent variable in the linear equation.
The value of independent variables can be changed by us whereas the value of dependent variables changes on the basis of the value of independent variables.
Hence, the value of independent variables can be changed by us whereas the value of dependent variables changes on the basis of the value of independent variables.

Solomon has taken two tests each out of ten. his average score is 18. if the product of his scores is 56. what did he score in each test ?
The scores of both test Solomon took are 14 for the first test and 4 for the second test.
How to calculate the score of bother test?let a represent the first score and b represent the second score.
since the average score is 18, you get (a + b) / 2 = 18
multiply both sides of this equation by 2 to get a + b = 36
the product of her scores is 56 means that a × b = 56.
you have 2 equations that need to be solved simultaneously.
they are a + b = 36 and a × b = 56
solve for a in the second equation to get a = 56 / b.
replace a with 56/ b in the first equation to get 56/ b + b = 18
multiply both sides of this equation by b to get 56 + b^2 = 18b
subtract 14b from both sides of this equation and arrange the terms in descending order of degree to get b^2 - 18b + 56 = 0
Factorise the quadratic equation to get the following:
(b-4 ) ( b - 14) = 0
Solve for b to get b = 4 and b = 14
Therefore, the product of the of the two scores:
= 14×4 = 56. This means that he scored 14 in first test and 4 in the second test.

Assume that all variables are implicit functions of time t. Find the indicated rate. x^2 + 5y^2 + 2y = 75; dx/dt = 14 when x = 6 and y = -3: find dy/dt
The answer to the given question, assuming that all variables are implicit functions of time t, the indicated rate x^2 + 5y^2 + 2y = 75; dx/dt = 14 when x = 6 and y = -3 is dy/dt = 6.
What is implicit function?An implicit function is a function which is defined by an implicit equation, written in terms of both dependent and independent variables. While an explicit function is a function which is represented in terms of an independent variable.
In this case, we have equation:
x^2 + 5y^2 + 2y = 75
We use the chain rule to bridge it:
2x(dx/dt) + 10y(dy/dt) + 2(dy/dt) = 0
Since x = 6; y = -3; and dx/dt = 14, then:
2x(dx/dt) + 10y(dy/dt) + 2(dy/dt) = 0
2*6*14 + 10*(-3)*(dy/dt) + 2*(dy/dt) = 0
168 + (-30)(dy/dt) + 2(dy/dt) = 0
168 - 28(dy/dt) = 0
28(dy/dt) = 168
dy/dt = 6
Hence, the indicated rate x^2 + 5y^2 + 2y = 75; dx/dt = 14 when x = 6 and y = -3 is dy/dt = 6.

1. suppose we wish to predict average customer spending. we take a small sample of size 50 and find the sample mean to be $200/mo. with a sample standard deviation of $10/mo. place a 99% confidence interval around the population average spending.
The average customers are spending in the range of ( 196.36 , 203.64) for the given mean and standard deviation.
As given in the question,
Sample size 'n' = 50
Sample mean 'μ ' is equal to 200
Standard deviation 'σ' = 10
z-score for 99% Confidence interval = 2.576
Confidence interval = mean ± z ( σ / √n )
Substitute the values we get,
Confidence Interval = 200 ± 2.576( 10 / √50)
= 200± 2.576 ( 1.414)
= 200 ± 3.642464
Lower bound of the required confidence interval = 200 - 3.642464
= 196.36
Upper bound of the required confidence interval = 200 + 3.642464
= 203.64
Therefore, the average customer is spending between ( 196.36 , 203.64) range from the given mean and standard deviation.

How to carry out hypothesis testing?Hypothesis testing is defined as the method used to find the probability of the hypothesis that is to be proved in the future on the basis of the small population sample.
Now, we are told that Among 20,111 responses, 67 % were "yes." Thus;
Sample proportion; p^ = 67%
The population proportion is not given and as such we will use; p = 50% = 0.5
Thus;
Null Hypothesis; p = 0.5
Alternative Hypothesis; p < 0.5
The formula for the test statistic is;
z = (p^ - p)/√(p(1 - p)/n)
z = (0.67 - 0.5)/√(0.5(1 - 0.5)/20111)
z = 48.216
The p-value from online p-value from z-score calculator is;

The family can spend 1 hour on the trampoline and 2 hours in the pool and the inequalities are 10t + 5p ≤ 25 and t + p < 4.
How many hours can the family spend within the budget?
a ) Let the time on the trampolines = t

The time constraints is represented with the system of inequalities by :t + p < 4
b )No, the family cannot spend 1 hour in the trampoline and 3 hours in the pool.
We can infer that this is the case because the family desires to spend less time together than 4 hours, which is what those periods total to.However, as we can plainly see, the point (1, 3)is not a solution because it is located on the dashed line of one graph.(Refer image for graph )c ) No, the family cannot spend 2 hours in the trampoline and 1.5 hours in the pool.
We are aware that these two periods total less than four hours.But we must compute the cost, which comes out to 27.5 and is higher than the budget.10t + 5p ≤ 25
10(2)+ 5(1.5) = 27.5
d ) Yes, the family can spend 1 hour on the trampoline and 2 hours in the pool.
We are aware that these two periods total less than four hours.We must compute the cost, which comes out to 20 and is lesser than the budget of 25 .The point (1,2)is a solution because it is not located on the dashed line but within the shaded region of the graph (Refer image for graph )10t + 5p ≤ 25

If a ray is positioned so that its terminal is on a line and the angles are also equal, the angles are said to be at right angles. The phrase derives from the Latin angulus rectus, where rectus denotes the upright vertical line that is perpendicular to a horizontal base line.
Perpendicular lines—defined as lines that meet at right angles—and orthogonality—defined as the ability to intersect at right angles—are closely connected and crucial geometrical notions.
Q and R create a right angle given.
Therefore, the angle formed by either Q or R is 90 degrees.
Angle R is doubled by the given angle Q.
From there, Q must have an angle of 90 degrees.
