Answer:
2 1/4 or 2.25
Step-by-step explanation:
2*3= 6
3/4*3= 2 1/4
Insert x = 7
so 3/(7+2) - sqr (7-3)
=3 / (9) - sqr (4)
= 1/3 - 2
=1/3 - 6/3
= -5/3
Answer:
All the left numbers of the Ratio go by 8's times tables and all the right numbers go by 5's times tables
Step-by-step explanation:
8x1= 8
8x2 =16
8x3 = 24
5x1= 5
5x2= 10
5x3= 15
Let me know if its right.
Hello!
<u>What is an x-intercept</u>:
⇒ <em>value of x</em> when the <em>value of y</em> equals '0'
x-intercept is <u>25/8</u>
<u></u>
<u></u>
<u>What is a y-intercept:</u>
⇒ <em>value of y</em> when the <em>value of x</em> equals '0'
y-intercept is <u>5</u>
<u></u>
Hope that helps!

First we find the common difference...to do this we subtract the first term from the second term. -7 - (-1) = -7 + 1 = -6
now we are going to find the 10th term
an = a1 + (n-1)*d <== formula for finding any term in arithmetic series
a1 = 1st term, d = common difference, n = term we want to find
now we sub
a10 = -1 + (10 -1) * -6
a10 = -1 + (9 * -6)
a10 = -1 - 54
a10 = - 55
now we will find the sum
Sn = (n (a1+ an)) / 2 <== formula for finding the sum
S10 = (10(-1 - 55))/2
S10 = (10(-56) / 2
S10 = -560/2
S10 = - 280
so the sum of the first 10 numbers is -280
