Write 2x+y=5 in slope intercept form
mylen [45]
2x+y=5
To put this in slope intercept form, you simply have to get y by itself on the left side of the equation.
2x+y=5
2x+y-2x=5-2x
y=-2x+5
Now, I had to switch the right side around like that, because slope intercept form is y=mx+b
Because you're subtracting 2x from 5, it becomes 5 added to -2x when it's put in the correct form.
y=-2x+5

A manufacturer wants to construct a box whose base length is 4 times the base width. The material to build the top and bottom co
Nitella [24]

Answer:

width = 1.77845 ft

length = 7.1138 ft

height = 5.691 ft

total cost = $759.09

Step-by-step explanation:

volume = length x width x height

length = 4 width

base of the rectangle = 4 x 1 w = 4w²

72 (volume) = 4w²h

18 = w²h

f(c) = (2 x 4w² x $10) + (2 x wh x $5) + (2 x 4wh x $5)

f(c) = 80w² + 10wh + 40wh

f(c) = 80w² + 50wh

since we need only 1 variable (width), we have to substitute h:

h = 18/w²

f(c) = 80w² + 50w(18/w²) = 80w² + 900/w

f'(c) = 160w + 900/w²

0 = (160w³ + 900)/w²

0 = 160w³ + 900

0 = 20(8w³ + 45)

0 = 8w³ + 45

8w³ = -45

w³ = -45/8

w = ∛-45/8 = -1.77845 and 1.77845

since w cannot be negative, then it must be 1.77845

10. Higher Order Thinking One day,
hram777 [196]

126,945 ≈ 100,000 (to the nearest hundred thousand)

126,945 ≈ 130,000 (to the nearest ten thousand)

126,945 ≈ 127,000 (to the nearest thousand)

The amount that is closest to the actual attendance is 127,000

<h3>Rounding numbers</h3>

From the question, we are to round the given number

From the given information,

Total attendance at the state fair was 126,945

We are to round 126,845 to the nearest hundred thousand, nearest ten thousand and nearest thousand

5 is the units digit

4 is the tens digit

9 is the hundreds digit

6 is the thousands digit

2 is the ten thousands digit

1 is the hundred thousands digit

To the nearest hundred thousand

Since to is less than 5, we will round the number down

Thus,

126,945 ≈ 100,000

To the nearest ten thousand

Since 6 is greater than 5, we will round up

126,945 ≈ 130,000

To the nearest thousand

Since 9 is greater than 5, we will round up

126,945 ≈ 127,000

Hence, the amount that is closest to the actual attendance is 127,000
