Answer:

  4)  (4, 0)

Step-by-step explanation:

I find it useful to graph the inequalities and the points.

The point on the dashed line is not in the solution set. The only point in the doubly-shaded area is (4, 0), choice (4).

__

Another method of choosing the points is to try them in the inequalities. I find it easier to do the math if the inequalities are written in standard form:

  2y < x +8 . . . . . multiply the first by 2

  x -2y > -8 . . . . . add -8-2y and swap sides. This is the first inequality.

__

  y ≥ -x +1

  x + y ≥ 1 . . . . .  add x. This is the second inequality

__

For the four points in the first inequality, we have ...

  1) -5 -2(3) = -11  . . .  not greater than -8

  2) 0 -2(4) = -8 . . . not greater than -8

  3) 3 -2(-5) = 13 . . . greater than -8, satisfies the first inequality

  4) 4 -2(0) = 4 . . . greater than -8, satisfies the first inequality

__

So, the two points that might possibly work are (3, -5) and (4, 0). Here, we try these in the second inequality.

  3) 3 -5 = -2 . . . less than 1

  4) 4 + 0 = 4 . . . greater than 1, satisfies the second inequality

The only point listed that is a solution to the system is (4, 0), point 4.

The graph of f(x)=3x is reflected across the x-axis. Write a function g(x) to describe the new graph.

g(x)=___

Answers

Answer:

g(x) = -f(x)

Step-by-step explanation:

When we have a point (x, y) and we reflect it over the x-axis, the result of the reflection is the point (x, -y)

The graph of f(x) = 3x is reflected across the x-axis is g(x) = f(-x) = 3x.

What is a graph?

A graph can be defined as a pictorial representation or a diagram that represents data or values.

What is a reflection across the x-axis?

Reflection across the x-axis is defined as reflecting a point across the x-coordinate and y-coordinate change places, and When we have a point (x, y) and we reflect it over the x-axis, the result of the reflection is the point (x, -y)

To determine the graph of f(x) = 3x is reflected across the x-axis.

So the graph of f(x) = 3x is reflected across the x-axis.

⇒ g(x) = f(-x) = 3x

Hence, the graph of f(x) = 3x is reflected across the x-axis is  g(x) = f(-x) = 3x.

you bought 5 chocolate bars and 8 blow pops for $23.25 your sister bought 2 chocolate bars and 13 blow pops for 21.55 how much did each chocolate bar cost?

Answers

Answer:

$2.65

Step-by-step explanation:

Let chocolate bar = c and blow pops = b

As per given we have equations below:

5c + 8b = 23.252c + 13b = 21.55

13 times the first equation minus 8 times the second to eliminate b and find c:

13(5c + 8b) - 8(2c + 13b) = 13(23.25) - 8(21.55)65c - 16c = 129.8549c = 129.85c = 129.85/49c = 2.65

Each chocolate bar costs $2.65

A cycle was purchased for Rs 1600 and sold for Rs1200.Find the profit or loss %... I have done this questions is the answer 25%

Answers

Answer:

Yes

Step-by-step explanation:

Answer:

[tex]{\underline{\textsf{\textbf{True }}}}[/tex]

Your answer is 25% loss

Step-by-step explanation:

Proof :

Given that,

A cycle was bought for ₹1,600

And it's S. P. (selling price) is ₹1,200

As the C. P. (cost price) is more than the S. P.

Therefore,

➡ Loss = C. P. - S. P.

➡ Loss = 1,600 - 1,200

➡ Loss = ₹400

And also,

➡ Loss% = loss*100/C. P.

➡ Loss% = 400*100/1,600

➡ Loss% = 25%

Hence proved :)

if triangle fgh m f = m h, gf = x + 40, hf =3x - 20, and gh = 2x + 20. The length of GH is

Answers

Answer: it’s 60

Step-by-step explanation:

GH=2x+20=2(20)+20=40+20=60

When two angles are equal in a triangle the opposite sides of them are also equal. The value of the side GH is 60 units.

Given information-

In [tex]\Delta FGH [/tex],

[tex]m\angle f=m\angle h[/tex]

The sides of the triangle,

[tex]GF=x+40[/tex]

[tex]HF=3x-20[/tex]

[tex]GH=2x+20[/tex]

Isosceles triangle-

An isosceles triangle is a triangle in which two sides and two angle are equal.

When two angles are equal in a triangle the opposite sides of them are also equal. Therefore,

[tex]GF=GH\\ [/tex]

Put the values,

[tex]\begin{aligned}\\ x+40&=2x+20\\ 2x-x&=40-20\\ x&=20\\ \end[/tex]

Thus the value of the GH is,

[tex]GH=2x+20\\ GH=2\times20+20\\ GH=60[/tex]

Thus the value of the side GH is 60 units.
