Step 1: Define systems
2x - y = 9
4x² + 3y² - 2x + y = 16
Step 2: Rewrite systems
2x - y = 9
Subtract 2x on both sides: -y = 9 - 2xDivide -1 on both sides: y = 2x - 9Step 3: Redefine systems
y = 2x - 9
4x² + 3y² - 2x + y = 16
Step 4: Solve for x
Substitution
Substitute in y: 4x² + 3(2x - 9)² - 2x + (2x - 9) = 16Expand: 4x² + 3(4x² - 36x + 81) - 2x + (2x - 9) = 16Distribute 3: 4x² + 12x² - 108x + 243 - 2x + 2x - 9 = 16Combine like terms: 16x² - 108x + 234 = 16Factor GCF: 2(8x² - 54x + 117) = 16Divide 2 on both sides: 8x² - 54x + 117 = 8Subtract 8 on both sides: 8x² - 54x + 109 = 0Define variables: a = 8, b = -54, c = 109Resubstitute: [tex]x=\frac{54\pm\sqrt{(-54)^2-4(8)(109)} }{2(8)}[/tex]Exponents: [tex]x=\frac{54\pm\sqrt{2916-4(8)(109)} }{2(8)}[/tex]Multiply: [tex]x=\frac{54\pm\sqrt{2916-3488} }{16}[/tex]Subtract: [tex]x=\frac{54\pm\sqrt{-572} }{16}[/tex]Here we see that we start to delve into imaginary roots.

Answer:
8x + 5y > 400
(50, 0) for x-intercept
(0,80) for y-intercept
Step-by-step explanation:
We will let x be the # of tshirts and y be the # of hats.
The inequality is 8x + 5y > 400; the coefficient 8 comes from $8 per tshirt and 5 from $5 per hats.
For x intercept, you let y = 0;
8x + 5(0) = 400;
8x = 400; divide by 8
x = 50 or (50, 0)
For y intercept, you let x = 0;
8(0) + 5y = 400;
5y = 400; divide by 5
y = 80 or (0,80)

An inscribed angle in a circle intercepts an arc whose measure is greater than 180
The angle is..
Alway acute
Sometime acute
Never acute
Answers
Answer:
The correct option is;
Never acute
Step-by-step explanation:
When an angle intercepts an ark, we have;
The legs of the angle meets with the endpoints of the arc
Therefore, given that the arc is greater than 180°, and that the angle of the arc is the angle defined at the center of the circle, while the angle defined by the inscribed angle is defined at the circumference of the circle
By circle theorem, the angle at the center is twice that at the circumference, whereby the angle of the arc > 180°, the angle at the subtended by the inscribed angle will > 180°/2, which is > 90° or an obtuse angle

In manufacturing processes, it is of interest to know with confidence the proportion of defective parts. Suppose that we want to be reasonably certain that less than 4% of a company's widgets are defective. To test this, we obtain a random sample of 250 widgets from a large batch. Each of the 250 widgets is tested for defects, and 6 are determined to be defective, based upon the manufacturer's standards. Using α = 0.01, is this evidence that less than 4% of the company's widgets are defective? State the hypotheses, list and check the conditions, calculate the test statistic, find the p-value, and make a conclusion in a complete sentence related to the scenario.
Answers
Answer:
Less than 4% of a company's widgets are defective.
Step-by-step explanation:
In this case we want to be reasonably certain that less than 4% of a company's widgets are defective.
The significance level of the test is, α = 0.01.
The hypothesis can be defined as follows:
H₀: At least 4% of a company's widgets are defective, i.e. p ≥ 0.04.
Hₐ: Less than 4% of a company's widgets are defective, i.e. p < 0.04.
The information provided is:
n = 250
x = 6
The sample proportion is, [tex]\hat p=\frac{x}{n}=\frac{6}{250}=0.024[/tex]
Compute the test statistic value as follows:
[tex]z=\frac{\hat p-p}{\sqrt{\frac{p(1-p)}{n}}}\\\\=\frac{0.024-0.04}{\sqrt{\frac{0.04(1-0.04)}{250}}}\\\\=-1.29[/tex]
The test statistic value is -1.29.
The decision rule is:
The null hypothesis will be rejected if the p-value of the test is less than the significance level.
Compute the p-value as follows:
[tex]p-value=P(Z<-1.29)=0.0985[/tex]
So,
p-value = 0.0985 > α = 0.01.
The null hypothesis will not be rejected at 1% significance level.
Thus, there is not enough evidence to support the claim.
Conclusion:
Less than 4% of a company's widgets are defective.

Why is 50 miles per hour a unit rate, and 150 miles per 3 hours is n
Answers
Answer:
Step-by-step explanation:
In a unit rate, the denominator is always 1. So, to find unit rate, divide the denominator with the numerator in a way that the denominator becomes 1. For example, if 50km is covered in 5.5 hours, the unit rate will be 50km/5.5 hours = 9.09 km/hour.
Answer:
because unit rate means 1 hour not 3 hour.

Step-by-step explanation:
Not a function
In order for an equation to represent a function any single value of x must have at most one corresponding value of y which satisfies the equation.
For
x2+y2=9
(for example)
x=0
there are two values for y (namely +3 and −3) which satisfy the equation
If you plug this graph into a calculator, you will find that it is a graph of a circle.
Circles have the formula x2+y2=r2 if they are centered at the origin.
From that, we can find that the radius is 3, and it is centered at the origin.
To find the domain and range, we just find the largest and smallest x and y values.
Since the radius is 3, and the graph is centered at the origin, the largest x value is 3. Similarly, the smallest x value is -3.
The domain is −3≤x≤3
We can use the same thing for the range. The radius is 3, so the largest and smallest values of the y will be 3 and -3.
The range is -3≤y≤3
Answer:
See below
Step-by-step explanation:
6. Look at the graph of the equation x^2+y^2=8. Give its domain and range.
Both domain and range are: (- √8, √8) or (-2.828, 2.828)7. Use algebraic means to show that x^2+y^2=8 is not a function. Explain your process.
The vertical line test. If more than one point is crossed on the graph by a vertical line, then the relation is not considered to be a function.8. Is there any value(s) of the domain of x^2+y^2=8 that passes the vertical line test? If so, name the value(s) and state whether or not the existence of this value makes this relation a function. You can use Desmos to help you explore this idea, if needed.
There are two points - 2.828 and 2.828 that pass the vertical line test but all the other points don't, therefore this relation is not a functionWeekly salary: $650; earnings to date: $30,000.
