Answer:

0.8 i think

Step-by-step explanation:

Step 1: So i subtracted 8 from the postive 8 and 7.2

Step 2: Then I got 4x= -0.8 + 5x

Step 3: Now that were left with thart i subtracted 5 from the postive 5x and from the postive 4x

Step 4: I have -1 = -0.8

Step 5: subtract the -1 from the -1 and the -0.8 which will equal... a postive 0.8!

hope this helped and don't remove this pls

PLEASE HELP 30 POINTS Wendell is looking over some data regarding the strength, measured in Pascals (Pa), of some building mater
jarptica [38.1K]

Logarithmic functions and exponential functions are inverse and opposite of one another

The logarithmic function is y = \log_2(x), and the length at 8 pascals is 3 units

<h3>How to determine the logarithmic function</h3>

The exponential function is given as:

f(x) = 2^x

Express f(x) as y

y = 2^x

Swap the positions of x and y

x = 2^y

Take the logarithm of both sides

\log(x) = \log(2^y)

Apply the rule of logarithm

\log(x) = y\log(2)

Divide both sides by log(2)

y = \frac{\log(x)}{\log(2)}

Apply the change of base rule of logarithm

y = \log_2(x)

When the strength is 8 pascals, we have:

y = \log_2(8)

Express 8 as 2^3

y = \log_2(2^3)

So, we have:

y =3 \log_2(2)

Evaluate log 2 base 2

y =3

Hence, the logarithmic function is y = \log_2(x), and the length at 8 pascals is 3 units

Answer:

6.283 m

Step-by-step explanation:

2m is the length so half is the radius

the radius is 1

so if c=2\pi1

and \pi 3.14159

u get 6.283

2(3.14159) x 1 = 6.283

Help meeeee plzzzzzzzzzz i need this done
olchik [2.2K]

Answer:

1.) yes

2.) no

Step-by-step explanation:

1.) Yes

3x - 2y = 1

3(5) - 2(7) = 1

15 - 14 = 1

1 = 1

2.) No

2x + 8y = 26

2(-3) + 8(-4) = 26

-6 - 32 = 26

-38 ≠ 26

What is the slope of a line that is perpendicular to the line y = 8x + 5?
Pavel [41]

The slope of a line that is perpendicular to the line y = 8x + 5 will be -1/8.

<h3>What is the slope of perpendicular lines?</h3>

Suppose that first straight line has slope 's'

Let another straight line be perpendicular to this first line.

Let its slope be 'a'

Then due to them being perpendicular, they have their slopes' multiplication as -1

or

s x a = -1

s = -1/ a

Slope of line y = 8x + 5

s = 8

The slope of a line that is perpendicular to the line y = 8x + 5

8 x a = -1

a = -1/8

Thus, the slope is -1/8.

You charge customers $18.75 for lube service, parts, and labor. Assuming you take one hour's labor at $15, and the parts cost $3
hram777 [196]
Let
T---------> <span>the tax rate on the parts in $

we know that
$18.75=$15+$3.50+$T
T=18.75-15-3.5
T=$0.25
so
$3.50----------> 100%
$0.25--------> x
x=0.25*100/3.50------> x=7.14%------> x=7.1%

the answer is
7.1%</span>
