Answer:
3
Step-by-step explanation:
Given
y - 3 = 4(x - 0)
y - 3 = 4x
y = 4x + 3
Comparing with y = mx + c
we get
y-intercept (c) = 3

Step-by-step explanation:
0.9
There are five whole numbers between 1 and 150 that have exactly 3 different factors. Whole numbers between 1 and 150 with exactly 3 different factors must be the square numbers whose square roots are prime.
To find the complete list begin counting...
skip 1, not prime;
2 is prime and 2 squared is 4;
3 is prime and 3 squared is 9;
skip 4 b/c it is not prime;
5 is prime and 5 squared is 25;
6 not prime;
7 prime and 7 squared is 49;
8 not prime;
10 not prime;
11 prime and squared is 121;
12 is not prime;
13 prime, but squared it is greater than 150.
The complete list is 4, 9, 25, 49, and 121. 4 has 1, 2, 4;
9 has 1, 3, 9;
25 has 1, 5, 25 ;
49 has 1, 7, 49 ;
121 has 1, 11, 121.

Answer:
15x+9y= 360----------1
x+y= 30--------------2
Step-by-step explanation:
Step one:
given data
let adult be x
and child be y
A hairstylist charges $15 for an adult haircut and $9 for a child haircut
She wants to earn $360 dollars
15x+9y= 360----------1
and cut 30 haircuts this week
x+y= 30--------------2
Step two:
Hence the system of equations for the situation is given as
15x+9y= 360----------1
x+y= 30--------------2
