rtha’s text message plan costs $15.00 for the first 1000 text messages sent plus $0.25 per text over 1000 sent. Let represent the cost of sending text messages over 1000. Sketch a graph of this relationship and find and interpret the -intercept.

12850+=+10t

Step-by-step explanation:

if u need the steps its    Let b= Miriam's monthly bill

Let t= the number of text messages sent in the

month of June by Miriam

t+-+1000= the number of text messages over 1000

Miriam's monthly bill is:

b+=+10+%2B+.1%2A%28t+-+1000%29 dollars

Her monthly bill is $38.50. I'll show it in terms of cents

3850+=+1000+%2B+10%2A%28t+-+1000%29 cents

Subtract 1000 from both sides

2850+=+10%2A%28t+-+1000%29

2850+=+10t+-+10000

Add 10000 to both sides

hope you get is lol and practice more okay

good luck!

cutie~

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
