What is expanded form of 605,970
Luba_88 [7]
605,970 is expanded in this form:

(6 x 100,000) + (0 x 10,000) + (5 x 1,000) + (9 x 100) + (7 x 10) + (0 x1)

each number is multiplied to the corresponding place value.
6 is on the one hundred thousand place value
0 is on the ten thousand place value
5 is on the one thousand place value
9 is on the hundreds place value
7 is on the tens place value
0 is on the ones place value

OR

600,000 + 5,000 + 900 + 70 = 605,970

Anvisha [2.4K]
Start by taking the information we know, and write equations to represent the realationships:

1) "1/8 lbs less flour to make bread than to make cookies"         
     b=c-\frac{1}{8}

2) "1/4 lb more flour to make cookies than to make brownies:
     c=w+\frac{1}{4}

3) "she used 1/2 lb of flour ro make bread"
    b = \frac{1}{2}

From here you can solve for w using back substitution.

What is the equation when y=5x+4 is reflected over the x-axis, y-axis & y=x?
tigry1 [53]

Answer:

A) y=-5x-4

B) y=-5x+4

C) y=\frac{x-4}{5}

Step-by-step explanation:

So we have the equation:

y=5x+4

Let's write this in function notation. Thus:

y=f(x)=5x+4

A)

To flip a function over the x-axis, multiply the function by -1. Thus:

f(x)=5x+4\\-(f(x))=-(5x+4)

Simplify:

-f(x)=-5x-4

B) To flip a function over the y-axis, change the variable x to -x. Thus:

f(x)=5x+4\\f(-x)=5(-x)+4

Simplify:

f(-x)=-5x+4

C) A reflection over the line y=x is synonymous with finding the inverse of the function.

To find the inverse, switch x and f(x) and solve for f(x):

f(x)=5x+4

Switch:

x=5f^{-1}(x)+4

Subtract 4 from both sides:

x-4=5f^{-1}(x)

Divide both sides by 5:

f^{-1}(x)=\frac{x-4}{5}

And we're done :)

Help will give 25 brainlest points
Alekssandra [29.7K]

Step-by-step explanation:

The ratio of the two shorter legs of the top triangle is

\dfrac{5}{4} = 1.25

The bottom triangle has the following ratio:

\dfrac{7.5}{6} = 1.25

Since their ratios are the same, this means that the two triangles are similar.
