Answer:
y > 2x - 1
y ≤ 0.5x + 4
Step-by-step explanation:
solid line: (0,4) (-8,0)
m: (0-4)/(-8-0) = -4/-8 = 0.5
b: 4
y = mx + b y = 0.5x + 4
dotted line: (0,-1) (-2,-5)
m = (-5 - -1)/(-2-0) = 2
b = -1
equation: y = 2x - 1
System: y ≤ 0.5x + 4
y > 2x - 1

You now have a lot of experience working with equations that compare two quantities. For example, while working with the height of a tree, you found the
relationship y = 41+5. which compared 2 (the number of years after it was planted) with y (its height in feet). Use the equation for this tree to answer the
questions below
a. What was its starting height? How can you tell from the equation?
Answers
Answer:
If you mean y = 4x + 5, then the answer is 5 (the height would be 5 feet)

2
Step-by-step explanation:
When two angles are complementary they add up to 90 degrees
so for example if angle 1 is 2 angle two must equal 88 (they have to add up to 90)
When two angles are supplementary they must add up to 180 (so it's the same process as table 1 but instead of adding to 90 it's 180)
Answer:
m<2 88,80, 65, 57, 50, 41, 35, 28, 14, 4
m<4 176, 164, 132, 108, 90, 81, 60,28, 11, 2
Step-by-step explanation:
complementary means they add up to 90°
m<2 88,80, 65, 57, 50, 41, 35, 28, 14, 4
supplementary means they add up to 180°
m<4 176, 164, 132, 108, 90, 81, 60,28, 11, 2
Missy uses 1 hexagonal, 3 rectangular, and 4 triangular pieces of fabric to make 1 bug design for a quilt. If she uses 80 pieces in all to make bug designs, how many of each shape does she use?
Answers
Answer:10 hexagonal, 30 rectangular and 40 triangular pieces of fabrics
Step-by-step explanation:
This question is a ratio/proportion question
The ratio of hexagonal pieces use to rectangular pieces used and to triangular pieces used can be expressed as 1:3:4
Total pieces of fabrics used = 80
Total ratio = 1 + 3 + 4 = 8
We can calculate each ratio as a proportion of the total ratio
pieces of hexagonal used = (1/8) * 80 =10
Pieces of rectangular used = (3/8) * 80 =30
Pieces of triangular used = (4/8) * 80 = 40
And hence the pieces of each shapes used will be 10 hexagonal, 30 rectangular and 40 triangular pieces of fabrics
And the total number of bugs designs made = (80/8) = 10 (since it will require 8 pieces of fabrics(1 + 3 +4) to make a bug design)

You can eliminate fractions by multiplying both sides by 12.

Answers
Answer: Choice D) As the side length increases by 1, the area increases and then decreases by an equal factor
=============================================================
Explanation:
Choice A is ruled out because the area does change. As x changes, y changes as well. This rules out choice B as well.
Choice C is somewhat close. However, it's not entirely true since the area doesn't increase by the same amount. For instance, the jump from points (2,18) to (3,24) indicate that the jump in y value is +6. But going from (3,24) to (4,28) shows a jump of +4 in the y value. So we can rule out choice C.
This means that choice D is the final answer.

The solution of (10 x/6)(10 x/8) = 1010 is
Answers
The solution to the exponential expression is given as follows:
x = 34.29.
How to solve the exponential expression?
The exponential expression for this problem is defined as follows:
[tex]10^{\frac{x}{6}} \times 10^{\frac{x}{8}} = 10^{10}[/tex]
When two terms with the same base and different exponents are multiplied, we keep the base and add the exponents.
The sum of the exponents is given as follows:
x/6 + x/8 = 4x/24 + 3x/24 = 7x/24.
Hence the equivalent expression is given as follows:
[tex]10^{\frac{7x}{24}} = 10^{10}[/tex]
The function 10^x is an injective function, hence the value of x is obtained as follows:
7x/24 = 10
7x = 240
x = 240/7
x = 34.29.

Si mi mamá compra un refrigerador del costo de $11,780 y con el descuento del 25% cuanto pagara en total mi mamá
Answers
Answer:
Precio a pagar= $8,835
Step-by-step explanation:
Costo de lista del refigerador= $11,780
Porcentaje de descuento= 25% = 0.25
Para calcular el precio que va a pagar con el descuento aplicado, tenemos que usar la siguiente formula:
Precio a pagar= costo de lista*(1- porcentaje de descuento)
Precio a pagar= 11,780*(1 - 0.25)
Precio a pagar= 11,780*0.75
Precio a pagar= $8,835

[tex]x = 1 + \sqrt{2} \ \ or \ 1- \sqrt{2}[/tex]
Step-by-step explanation:
Given;
x² - 2x - 1 = 0
Solve by completing the square method;
⇒ take the constant to the right hand side of the equation.
x² - 2x = 1
⇒ take half of coefficient of x = ¹/₂ x -2 = -1
⇒ square half of coefficient of x and add it to the both sides of the equation
[tex]x^2 + (-1)^2 = 1 + (-1)^2[/tex]
[tex](x-1)^2 = 1 + 1\\\\(x-1)^2 = 2\\\\[/tex]
⇒ take the square root of both sides;
[tex]x-1 = +/- \ \ \sqrt{2} \\\\x = 1 + \sqrt{2} \ \ or \ 1- \sqrt{2}[/tex]
Therefore, option B is the right solution.

This ellipse is centered at the origin. Find it’s equation. Verticles: (0,-6) (0,6) Foci: (0,-2) (0,2)
Answers
The equation of the ellipse will be x² / 36 – y² / 32 = 1.
What is an ellipse?An ellipse is a locus of a point that moves in a plane such that the sum of its distances from the two points called foci adds up to a constant. It is taken from the cone by cutting it at an angle.
This ellipse is centered at the origin.
Vertices: (0,-6) (0,6)
Foci: (0,-2) (0,2)
Then the equation of the ellipse will be given as
x² / a² – y² / b² = 1
Let c be the distance between the origin to foci.
Then we have
c = 2
And the value of a will be
a = 6
Then the value of a² will be
a² = 6² = 36
The value of b is the distance from center to one of the Co-vertices. Then the value of b² will be
a² – b² = c²
36 – b² = 2²
b² = 36 – 4
b² = 32
Then the equation of the ellipse will be x² / 36 – y² / 32 = 1.
