Here's an example
Y=5x + 10
if x is equal to 5 you would make it
Y=5(5)+10.
basically, just replace the x with what it's equal to.

tom had a platter of chocolate wafers. he ate 5 of them and then gave his brother 3 he then moved on to his baseball team of 8 m
Aloiza [94]

Tom started with total 72 chocolate wafers.

<u><em>Explanation</em></u>

The number of chocolate wafers taken by 8 members of the baseball team are in the sequence :  1, 3,5,7,9,11,13,15

The above sequence is <u>arithmetic sequence</u> with first term(a₁)= 1 and common difference (d) = 2

<u>Formula for Sum</u> of first n terms in arithmetic sequence is....

S_{n}= \frac{n}{2}[2a_{1}+(n-1)d]

So, the Sum of 8 terms in that sequence....

S_{8}= \frac{8}{2}[2(1)+(8-1)(2)]\\ \\ S_{8}= 4[2+7(2)]\\ \\ S_{8}=4(2+14)\\ \\ S_{8}=4(16)=64

That means, the total number of chocolate wafers taken by the baseball team members is 64.  Tom ate 5 and then gave his brother 3 chocolate wafers at first.

So, the total number of chocolate wafers at starting =64+5+3=72

Slope:<br> what is the slope?
Len [333]

Answer: -2

Step-by-step explanation:

So basically I located the y-intercept first. Where is that? At the point (0,-2). Now from there, I found the nearest point on an intersecting grid line, in this case it would be (-1,0). So from the y-intercept, I looked at how many spaces I would have to move to get to (-1,0). You would have to go up 2 spaces and to the left 1 space. This is also written as 2/-1. Simplify this and you get -2! Hope this helped!
