Which linear function represents the line given by the point-slope equation y-8=

Mathematics
1 answer:
Nina [5.8K]3 years ago
5 0

Answer:

f(x)=x+4

Step-by-step explanation:

we have

y-8=(x-4)

This is the equation of the line in point slope form

where

The slope is m=1

The point is (4,8)

Convert to slope intercept form

Isolate the variable y

Adds 8 both sides

y-8+8=x-4+8

Combine like terms

y=x+4

Convert to function notation

f(x)=x+4

SOLVE FOR X. pls i need help
Lyrx [107]
X=8
Set up proportions would give you: 10/3x+1 = 22/7x-1
With that in mind, cross multiply, which would give you: 10(7x-1) = 22(3x+1).
Turns into: 70x -10 = 66x+22. Then just solve for x

A construction crew built miles of road in days. What is the unit rate in miles per day? Write your answer as a fraction or a mi
vovikov84 [41]

Complete question :

A construction crew built 1/2 miles of road in 1/8 days. What is the unit rate in miles per day? Write your answer in simplest form.

Answer:

3 miles per day

Step-by-step explanation:

Given that:

1/2 miles of road takes 1/8 days

Unit Rate in miles per day :

Miles of road built / number of days taken

1/2 miles ÷ 1/8 days

1/2 * 8/1

= (1*8) / (2*1)

= 8/2

= 4

Unit Rate = 4 miles per day

​claim: the mean pulse rate​ (in beats per​ minute) of adult males is equal to 69 bpm. for a random sample of 140 adult​ males,
zaharov [31]

Answer:

93.19%

Step-by-step explanation:

We have that the mean (m) is equal to 70.4, the standard deviation (sd) 11.1 and the sample size (n) = 140

They ask us for P (x =69)

For this, the first thing is to calculate z, which is given by the following equation:

z = (x - m) / (sd / (n ^ 1/2))

We have all these values, replacing we have:

z = (69 - 70.4) / (11.1 / (140 ^ (1/2)))

z = 1.49

With the normal distribution table (attached), we have that at that value, the probability is:

P (z <1.49) = 0.9319

The probability is 93.19%
