This week we worked on inequalities with two variables. We used graphing to show what the inequalities looked like.
Question # 1: Describe a test you can use to see if a coordinate pair is the solution to an inequality using its graph.
Question #2: Which kind of line ( solid or dashed) is used for ?
Question #3: Now that we can graph an inequality in two variables>>> What do you think we will be trying to learn next week ?

Answers

Answer 1

Answer:

1. you have to describe a test so just tell of a test you took that was about graphing and has the symbols <, ≤, ≥, >

2. > or < is dashed line

   ≥ or ≤ is solid line

3. what do you think?

A parabola has focus (5,7) and directrix y=0(the X-axis). Write an equation that says point (x,y) is on the
parabola.

Answers

Answer:

Step-by-step explanation:

focus of the parabola is (2,0) and directrix is x=-2. Here,a=2.So, Equation becomes, y2=4∗2x⇒y2=8x, which is the required equation of parabola.

The equation of a parabola with the given focus and directrix is x²-10x+74=14y.

What is an equation of a parabola?

A parabola refers to an equation of a curve, such that a point on the curve is equidistant from a fixed point, and a fixed line

Given that, a parabola has focus (5,7) and directrix y=0.

When the focus (h, k) of a parabola and the equation of the directrix y = c are given, the equation of the parabola is given by (x-h)²+k²-c²=2(k-c)y

Here, y=c=0

Now, (x-5)²+7²-0²=2(7-0)y

x²-10x+25+49=14y

x²-10x+74=14y

Therefore, the equation of a parabola is x²-10x+74=14y.

Solve system of equations

3x+6y=18
X+3y=15

Answers

Answer:

x = - 12, y = 9

Step-by-step explanation:

Given the 2 equations

3x + 6y = 18 → (1)

x + 3y = 15 → (2)

Multiplying (2) by - 3 and adding to (1) eliminates the term in x

- 3x - 9y = - 45 → (3)

Add (1) and (3) term by term to eliminate x

- 3y = - 27 ( divide both sides by - 3 )

y = 9

Substitute y = 9 into either of the 2 equations and evaluate for x

Substituting into (2)

x + 3(9) = 15

x + 27 = 15 ( subtract 27 from both sides )

x = - 12

Solution is (- 12, 9 )

Do this equation have one solution, many solution, or no solution?

Answers

9514 1404 393

Answer:

  1 solution

Step-by-step explanation:

The coefficients of x are different on each side of the equal sign, so this equation has one solution.

_____

Additional comment

If the x-coefficients are the same on each side of the equal sign, then you need to look at the constants. If they are the same, there are an infinite number of solutions; if they are different, no solutions.

This equation simplifies to ...

  3x -3 = 2x +9

  x = 12 . . . . . . . . add 3-2x to both sides

The solution of expression by applying distributive property and combining like terms,

⇒ x = 12

Given that,

The mathematical expression is,

⇒ 3(x - 1) = 2x + 9

Now, simplify the expression by applying distributive property and combining like terms,

⇒ 3(x - 1) = 2x + 9

Apply distributive property,

⇒ 3x - 3 = 2x + 9

Combine like terms,

⇒ 3x - 2x = 9 + 3

Therefore, the solution of expression is,

⇒ x = 12
