Since we know the slope is 3 we have part of the equation already (y=3x+b). Now we need to find the y-intercept. To do that we plug in the point that was given to us in the question and solve for b.

0=3(-5)+b
0=-15+b
15=b

Now that we have the y intercept we can put the equation together.

Answer: y=3x+15

Hope this helps :)

What is the nth term in the sequence:<br> 4, 7, 12, 19, 28 <br> Please show working out
3241004551 [841]
                         4, 7, 12, 19, 28
1st difference    +3 +5 +7 +9
2nd difference      +2 +2  +2

This is a geometric sequence

The form is:
                  an² + bn + c
2a is always = to the second difference
2a = 2
a = 1

3a + b = 2nd term - 1st term
3(1) + b = 3
3 + b = 3
b = 0

a + b + c = 1st term
1 + 0 + c = 4
1 +c = 4
c = 3

nth term of sequence {substitute all we have found}
1n² + 0 + 3
n² + 3

The Split Ends Salon orders 10 cases of hand-made hairbrushes.
r-ruslan [8.4K]

Answer:

it would take 65 hours to produce all of the order.

Step-by-step explanation:

1. you already would figure out that 26 hours=4 cases or 6.5 hours per case of hairbrushes.

2. You would figure out that 26+26 is 52 so 52 hours for 8 cases

3. Then you remember u have 8 cases of hairbrushes now. Set up a mental equation where you can solve in your mind: if I need 10 cases, but have figured out I only calculated 8, how much more would I still need to meet the order?

4. After mentally solving the hypothetical problem, you then would conclude you needed 2 more cases from 8 to equal 10.

5. you then divide 26 hours per 4 cases and you get 13 hours for 2 cases.

6. finally you multiply 26+26+13 which you would get 65 as the answer

How many license plates can be made of the form XXXX?-YY?, where X is a letter of the alphabet and Y is a numeral? 0-9?
Alla [95]

Answer:  45,697,600

<u>Step-by-step explanation:</u>

There are 26 letters in the alphabet and numerals to choose from.  There is nothing that says that letters and numbers cannot be repreated. So,

   X  X  X  X  - Y  Y

= 26·26·26·26·10·10

= 26⁴(10)²

= 45,697,600
