An architect is building a scale model of an office building. The scale used to build the model is 1 120 .

Answer:

y=(-4/1)x-5

Step-by-step explanation:

You need to find the slope of the line and the y intercept, you can do this by plotting the points into a graph and figuring it out that way, or you can use the equations y2-y1/x2-x1 (for slope) and y=(*the slope from the other equation*)x+b. For both equations plug in a corresponding x and y coordinate given on the list (y1 and y2 would be consecutive coordinates, so 1 and 2, and same for x1 and x1, so -9 and -13). You should get (-4/1) for the slope, and when you plug that into the other equation you should get 5. Lastly you plug all these numbers into y=mx+b, and you get your answer.

Hope this helps :)

The equivalent value of the expression is y = ( 4x - 15 ) / 3

Given data ,

Let the equation be represented as A

Now , the value of A is

4x - 3y = 15

On simplifying the equation , we get

4x - 3y = 15

So , the left hand side of the equation is equated to the right hand side by the value of ( 15 )

Adding 3y on both sides , we get

3y + 15 = 4x

Subtracting 15 on both sides , we get

3y = 4x - 15

Divide by 3 on both sides , we get

y = ( 4x - 15 ) / 3

Therefore , the value of y = ( 4x - 15 ) / 3

Hence , the expression is y = ( 4x - 15 ) / 3

The radius of the basketball is 5 inches when the  volume of a basketball is about 435 cubic inches.

a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.

The formula for the volume of a sphere is V = 4/3πr³,

where V is the volume

and r is the radius.

Let us find the formula for r

3V/ 4π =r³

Take cube root on both sides

∛3V/ 4π = r

Now let us find the radius when the volume of a basketball is about 435 cubic inches.

∛3×435/ 4×3.14 = r

1305/12.56 = r

∛103.9 = r

4.7 = r

5=r

Hence, the radius of the basketball is 5 inches when the  volume of a basketball is about 435 cubic inches.

Answer:

Step-by-step explanation:

5 = 2/3 ( 8x - 6 )

to make it clearer, we can just interchange the position of LHS and RHS

2/3 ( 8x - 6 ) = 5

By transposing,

8x - 6 = 5 - 2/3

8x - 6 = 13/3

8x = 13/3 + 6

8x = 31 / 3

x = 31 / 3 × 1/8
