Write the decimal in expanded form using fractions

0.801 = ???

Answers

Answer: 8/10 + 1/1000

Step-by-step explanation: in decimal form we have 0.800 + 0.001

to convert this into a fraction you'd do 8/10 + 1/1000

(8 is in the tenths place therefore 8/10 and 1 is in the thousandths place therefore 1/1000)

A line passes through the point (4, - 7) and has a slope of
--
4
Write an equation in slope-intercept form for this line.

Answers

Answer: y = 4x-23

Step-by-step explanation:  I'm assuming the question asks:  "A line passes through the point (4, - 7) and has a slope of 4."  I had difficulty understanding the format of the question.  Slope intercept form is y=mx+b, where m is the slope and b is the y-intercept (the value of y when x=0).

We can start with y = 4x + b, since we are given the slope.  We can then use the given point (4,-7) to find b, since this point is on the line and thus satisfies the equation.

y = 4x + b

-7 = 4(4) + b

-7 = 16 + b

b = - 23

The equation is y = 4x-23

Which of the following is NOT a function?

Answers

Answer:

a x=-3

Step-by-step explanation:

The equation x = 3 represents a vertical line and not a mapping from values of x to values of y. For one thing, it fails the vertical line test for functions at the value x = 3.

Find angle x, and angle y

Answers

Answer:

x=40

y=40

Step-by-step explanation:

hlo there!

as the given is 90 ° in fig;

90+50+x= 180°( sum of angle of traingle)

x=180-140

x=40°

as there is alternate angle.

lets suppose the alternate angle of x is z

z=40°

now'

40 + 100+ y=180°( sum of angleof traingle)

y=40°

The pressure on a diver in the water varies directly as the depth. If the pressure is 3.6 Ib/in^2 when the depth is 8ft, what is the pressure when the depth is 30ft.

I give Brainliest! Please show your work

Answers

Answer:

13.5 lb/in^2

Step-by-step explanation:

8ft = 3.6 lb

30ft= ?

8ft÷30ft = 3.75

this means 8ft goes into 30ft 3.75 times

3.6lb× 3.75=13.5lb/in^2

you times the pressure of 8ft by 3.75 to find how much pressure there is at 30ft

(y²)³ = y⁶

Step-by-step explanation:

The power of a power rule is generally shows expressions where a power is being raised by another power. In such expressions, the exponents are multiplied together and the base is kept the same, like:

In order to write the expression (y²)³ in the form of yⁿ, you may use this rule (power of a power rule) to obtain the answer.
