Please help !! need answer as soon as possible
a) Find x and y

= mx +b

m is slope, geometrically. It means that rate of change is fixed

i.e.

A plumber charges $30 for service and $20 for every hour of work.

then Cost of fixing depends on number of hours of work done:, and the relation is given by the following equation:

C = 20t + 30

$30 is service charge that is called start of the process

$20 is the rate(per unit) change, means that for every hour of work he charges $20 fix.

Linear relation is where Relation is represented by a binomial Expression( consist of 2 terms)

the coefficient of the variable( 20) is the fixed rate of change,

30 is the value of C at start of the point in the context of this problem will be service call.

In graph of the equation. $30 will be the C(vertical intercept), and $20 will be slope.

The feature of linear relation is that rate of change, rise/ run and slope is fixed.

x = 5 ; y = 14

Step-by-step explanation:

2x = 10

x = 5

y + 2 = 16

y = 14

9) i can't see the angle so whatever it is just do this: cos(angle) x hypotenuse and then use that answer and they hypotenuse and plug it into this: (answer you just got)^2 + b^2 = (hypotenuse)^2. the first answer will be the answer of the adjacent side and the second answer after this equation will be the opposite side.

10) y = 14 x = √147 or 12.12435565

11) x = 4.8

12) x = 4.2

13) x = 9.3

14) pq: 13.2

qr : 17.6

angle p: 53º

15) angle c: 54.3º

angle a: 35.7º

16) h = 21040

v = 1841

step-by-step explanation:

10) 7/sin(30) = 14 = y

7^2 + b^2 = 14^2

49 + b^2 = 196

b^2 = 196 - 49

√b^2 = √147

x = √147

11) cos(70) x 14 = 4.788282007

x = 4.8

12) tan(25) x 9 = 4.196768923

x = 4.2

13) sin(31) x 18 = 9.270685348

x = 9.3

14) pq: sin(37) x 22 = 13.23993051

pq: 13.2

qr: cos(37) x 22 = 17.56998122

qr : 17.6

angle p: 180 - (37 + 90) = 53º

15) cos-1(7/12) = 54.31466529

angle c: 54.3º

angle a: 180 - (90 + 54.31466529) = 35.68533471

angle a: 35.7º

16) 4 x 5280 = 21120

cos(5) x 21120

h = 21039.63202

h = 21040

sin(5) x 21120

v = 1840.729287

v = 1841
