Answer:

1:70

Step-by-step explanation:

A scale drawing is a reduced form in terms of dimensions of an original image / building / object

the scale drawing is usually reduced at a constant dimension

scale of the drawing = original dimensions / dimensions of the scale drawing

245 / 3.5 = 70

1:70

Answer:

The last listed functional expression:

\left \{ {x+1\,\,\,\,{x\geq 2} \atop {x+2 \,\,\,\,x

Step-by-step explanation:

It is important to notice that the two linear expressions that render such graph are parallel lines (same slope), and that the one valid for the left part of the domain, crosses the y-axis at the point (0,2), that is y = 2 when x = 0. On the other hand, if you prolong the line that describes the right hand side of the domain, that line will cross the y axis at a lower position than the previous one (0,1), that is y=1 when x = 0. This info gives us what the y-intercepts of the equations should be (the constant number that adds to the term in x in the equations: in the left section of the graph, the equation should have "x+2", while for the right section of the graph, the equation should have x+1.

It is also important to understand that the "solid" dot that is located in the region where the domain changes, (x=2) belongs to the domain on the right hand side of the graph, So, we are looking for a function definition that contains x+1 for the function, for the domain: x\geq 2.

Such definition is the one given last (bottom right) in your answer options.

\left \{ {x+1\,\,\,\,{x\geq 2} \atop {x+2 \,\,\,\,x

A furniture store bought a couch for $425 and marked the price up by 70%. Angela bought the couch with a 6% tax. How much did An
Tomtit [17]

Answer:Angela paid 679,05 for the couch

Step-by-step explanation:

 425*70/100=29.750

29.750/100= 297,5

297,5+425=722,5

722,5*6/100=4.335/100=43,45

722,5-43,45=679,05

Write the equation 2y-4x=5 In the form y=my+b
Vika [28.1K]

Answer:

y = 2x + 2.5

Step-by-step explanation:

To begin, we start with the equation 2y - 4x = 5.

We will add 4x to both sides to move the x term to the right side of the equation, giving us:

2y - 4x + 4x = 4x + 5

2y = 4x + 5

Next, we should divide by 2 to cancel out the coefficient on the y-term and isolate it on the left side of the equation:

2y/2 = 4x/2 + 5/2

y = 2x + 5/2

Therefore, your answer is y = 2x + 5/2 or y = 2x + 2.5.

Hope this helps!

Express it in slope-intercept form.
FinnZ [79.3K]

Answer:y=3/2x-3

Step-by-step explanation: the slope of the graph is (y2-y1)/(x2-x1)

If we take points (0,-3) (2,0) the slope would be (0--3)/(2-0) = 3/2

And the y-intercept of the slope is -3

-2x+5/-5x-7 simplify
Yakvenalex [24]

Hello from MrBillDoesMath!

Answer:

-3x - 7


Discussion:

The order of operations states that multiplication and division are done before addition\subtraction.  So

-2x +5/-5x - 7 =            

-2x + (5/-5x) - 7   -

-2x -x -7 =

-3x - 7



Thank you,

MrB
