An investment firm wants to create a billboard that displays an enlarged $1,000,000 bill. The actual size of the bill is 2.61 in

ches by 6.14 inches. If the billboard is 48 feet wide, what's the scale of the bill to the billboard? A. 1′ = 8.71″ B. 1′ = 7.81″ C. 1″ = 8.71′ D. 1″ = 7.81′

We know how wide the billboard will be. Therefore, to know how much the original image should be enlarged, you must divide the final width of the billboard between the current width of the invoice.

We know both data, then we perform the operation:

48 feet /6.14 inches = 7.81 feet / inches .


Therefore the correct answer is option D. 1″ = 7.81′

For the bill to cover the billboard, the bill must be expanded by a factor of 7.81 feet long per inch long that has the original image.

Write the standard form equation of the line through the given points. through (0.-4) and (-3,-2)
Alexxx [7]

Answer:

The standard form of equation of the line through the given points. through (0.-4) and (-3,-2) is \frac{2}{3}x+y=-4

Step-by-step explanation:

The standard form of equation is Ax+By=C

Finding slope

Using the given points (0,-4) and (-3,-2) we can find slope using formula:Slope=\frac{y_2-y_1}{x_2-x_1}

Slope=\frac{-2-(-4)}{-3-(0)}\\Slope=\frac{-2+4}{-3}  \\Slope=-\frac{2}{3}

Finding y-intercept

Using point (0,4) and Slope=-2/3 we can find y-intercept

y=mx+b\\-4=-\frac{2}{3}(0)+b\\-4=0+b\\b=-4

The slope intercept form of the line through the given points. through (0.-4) and (-3,-2) having slope =-2/3 and b=-4 will be:

y=mx+b\\y=-\frac{2}{3}x-4

Now, standard form of equation will be: \frac{2}{3}x+y=-4

So, The standard form of equation of the line through the given points. through (0.-4) and (-3,-2) is \frac{2}{3}x+y=-4

Which are steps that could be used to solve 0 = 9(x2 + 6x) – 18 by completing the square? Check all that apply.
mihalych1998 [28]

Answer:

A) 18+81=9(x^2+6x+9)

D)11+(x+3)^2

Step-by-step explanation:

To solve this by completing the square, we want to get it to the form of: (x + 3)^2 = 9

There are multiple ways to get there.

First we could divide by 9 to get.

x^2 + 6x = 0

Then, add 9 to both sides to get:

x^2 + 6x + 9 = 9

Factor the left side:

(x + 3)^2 = 9

Now, you can solve this equation by completing the square.
