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)

If the trapezoid is isosceles, and KL = 2.8 units in length, what is the length of NM? Explain how you determined the length of NM.
Answers
Answer:
MN = 2.8 units
Step-by-step explanation:
By the property of isosceles trapezoid,
1). Bases are parallel.
2). Base angles of an isosceles trapezoid are congruent.
2). Opposite sides of the congruent angles are congruent.
By third property,
Measure of side KL = Measure of side MN
2.8 = Measure of side MN
Another way to find the length of MN is,
Distance between M and N = [tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
MN = [tex]\sqrt{(3-1)^2+(0+2)^2}[/tex] = [tex]\sqrt{8}[/tex]
MN = 2.8 units
Therefore, MN = 2.8 will be the answer.

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

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.

Solving systems of equations using substitution/eliminationSolving systems of equations by graphingExpandingFinding roots of a quadraticStandard Form: ax² + bx + c = 0Quadratic Formula: [tex]x=\frac{-b\pm\sqrt{b^2-4ac} }{2a}[/tex]Step-by-step explanation:
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:
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 function
