Answer: I’m pretty sure it’s y=1/x+5 +2

Step-by-step explanation:

The graph of Function  [tex]y = \frac{1}{x-5}+2[/tex] is same as the graph of [tex]y = \frac{1}{x}[/tex]

"A graph can be defined as a pictorial representation or a diagram that represents data or values in an organized manner."

"Function, an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable)."

We have

[tex]y = \frac{1}{x}[/tex]

The function is shifted 5 units right

⇒[tex]y = \frac{1}{x-5}[/tex]

The function is shifted 2 units up

⇒[tex]y = \frac{1}{x-5}+2[/tex]

Hence, function becomes  [tex]y = \frac{1}{x-5}+2[/tex]

Answer:

1.5

Step-by-step explanation:

Because the triangle are similar, they possess a proportional relationship in which the one triangle's side length is dilated by a unknown factor (y) to make its corresponding counterpart. Using this knowledge we can make the following two equations

3y=7  & xy=x+2   y is the variable representing the dilation factor

y=7/3 find the value of y

x(7/3)=x+2 substitute the value y into the equation

7/3x =x+2 solve for x

4/3x =2

(3/4)(4/3x)=2(3/4) multiply by the reciprocal

x=1.5

Answer:

b and c

Step-by-step explanation:

Hope this helps!

B and C

first isnt right because the prouduct is higher than 4(sum). 3b+1b=4b. 2x2=4 so B AND C!

Answer:

A: 907-789=p

B: 118 bought tickets but didn't go.

Step-by-step explanation:

907 is the people that bought the tickets, you subtract the people that did go which is 789 which would give you the people that didn't go but still bought tickets.

Answer:

The answer is "[tex]240 \ m^2[/tex]"

Step-by-step explanation:

please find the given diagram image file in the attachment.

In this question, the surface area model includes two things that are square pyramid is equal to the area of the square base and the area of the flour lateral triangle:

[tex]SA= 10\times 10 +4 (\frac{1}{2}\times (10) \times (7))\\\\[/tex]

     [tex]= 100 +4 (\frac{1}{2} \times 70)\\\\= 100 +4 (35)\\\\= 100 +140\\\\=240 \m^2\\\\[/tex]

The surface area of the model is [tex]240 \ m^2[/tex].

Answer:

d. 540 deg

Step-by-step explanation:

2 pi radians = 360 deg

(360 deg)/(2pi rad) = 1

3 pi * (360 deg)/(2 pi rad) = 3 * 180 deg = 540 deg

Answer: y= -6x + 0

Step-by-step explanation:

Each number is subtracted by 6 to get to the next.. so m from y=Mx+b would be -6.

Since b= initial value (value at 0)...the value at 0 is 0 so the equation formula would be y= -6x+ 0

Answer:

When there is no width, the area is 0m²

Step-by-step explanation:

Expressing the area of a rectangle as a function of its width:

Area of a rectangle = Length * width

Since the area of rectangle is related to the width by the multiplication operatkr. We can conclude from the options given that ; if the value of width = 0 ; the the area of rectangular plot = 0

When x :

Area = Length * width

Area = Length * 0

Area = 0

Area = Length * 0

Aea = 0

Answer:

50.27

Step-by-step explanation:

The shape is a circle

Radius is 4

Diameter is 8  (diameter is always double of the radius)

π * r^2 = π * 16 ft^2 = 50.27 ft^2

(16 = 8 * 2)

Answer:

127.5

Step-by-step explanation:

First, we need to find the value of x

since the two angles are connected to a straight line, their sum will be 180 (degrees)

[tex](2x+7)+(6x-9)=180^{o}[/tex]

add the angles together

[tex]\therefore 8x-2=180[/tex]

add 2 to both sides

[tex]\therefore 8x=182[/tex]

divide out by 8

[tex]\therefore x = 22.75[/tex]

now we must determine which angle has the greater value (not visually)

[tex]angle A = 2x+7[/tex]

[tex]\therefore \angle{A} = 2(22.75)+7[/tex]

[tex]\therefore \angle{A} = 45.5+7[/tex]

[tex]\therefore \angle{A} = 52.5[/tex]

[tex]angle B = 6x-9[/tex]

[tex]\therefore \angle{B} = 6(22.75)-9[/tex]

[tex]\therefore \angle{B} = 136.5-9[/tex]

[tex]\therefore \angle{B} = 127.5[/tex]

[tex]\angle{B}>\angle{A}\ \because\ 127.5>52.5[/tex]

so the answer would be 127.5
