75.89 + 0.12x = 27.41 + 0.36x
75.89 - 27.41 = 0.24x
48.48 = 0.24x
x = 48.48 / 0.24
x = 202
Each sent 202 text messages
a) (0; -15)
you just let x be equal to 0.
b) ( -5; 0) and (3;0)
you just let y/ f(x) equal to 0.
c)
2=28 divide both get 14 . So each cd is 14$. So now 28+28=56 (4 cd's) plus 14 (1 more cd) =5 so 5 is 70.
Answer:
All real numbers / (-∞, ∞) / R
Step-by-step explanation:
The equasion provided is a linear equasion meaning it can be written in the y=ax+b format, where both a and b are real numbers. All linear eqasions have a range of all real numbers, you can write this using the three solutions provided.
You can solve this two ways, number one would be to put this in a graphing calculator and number two would be reducing the equasion to the y=ax+b format.
<h2>Method 1:</h2>
look at image provided. The app is PhotoMath.
<h2>Method 2:</h2>
Write the equasion:
y = -2x - 6x + 1
Collect like terms:
y = -8x + 1
This now proves that the equasion is linear becuase you can write it in the y=ax+b format. a being -8 and b being 1.
Answer:
18
Step-by-step explanation:
After 2 days hunter bought 12 souvenirs. So we can assume he bought 6 each day, (12 dived by 2 equals 6). Add one more day (6 more souvenirs) onto the total. So for 3 days, he will have bought 18 souvenirs.
