its 13 people by Thursday
Step-by-step explanation:
if Ethan send the email to 3 people on Monday that means he also had the email on Monday so that's 3+1=4 and the next day would be Tuesday that's 3 more people and 3+4=7 so by tuesday there would be 7 people then theres Wednesday that's 3 more people if you do 3+7=10 that's 10 by Wednesday then theres thursday 3 more people 10+3=13 that's how I got my answer to you
The factored form of the equation that has the zeros 4 and -7 is y = ( x - 4)( x + 7 ).
<h3>What is the factored form of an equation that has the zeros or roots 4 and -7?</h3>
Roots are simply the points where the graph intercepts with the x-axis. ( y = 0 )
That is, y = 0 the roots
Given the roots of the equation;
Now, at x = 4,
x = 4
x - 4 = 0
y = ( x - 4)
Also, at x = -7,
x = -7
x - ( - 7 ) = 0
x + 7 = 0
y = ( x + 7 )
Hence; for the equation with the given roots; 4 and -7 will be;
y = ( x - 4)( x + 7 ).
The factored form of the equation that has the zeros 4 and -7 is y = ( x - 4)( x + 7 ).

The relation between the Pattern A is the half of the Pattern B is given below. Then the correct option is C.
<h3>What are ratio and proportion?</h3>
A ratio is a collection of ordered integers a and b represented as a/b, with b never equaling zero. A proportionate expression is one in which two items are equal.
Molly is studying two number patterns.
Pattern A starts at 0 and has the rule “add 3”.
Pattern B starts at 0 and has the rule “add 6”.
The relation between the Pattern A and Pattern B is given below.
Pattern A = 1/2 x Pattern B
Then the correct option is C.

I would think that all but one point would be on the line. One way to approach this problem is to find the equation of the line based upon any two points chosen at random, and then determine whether or not the other points satisfy this equation. Next time, would you please enclose the coordinates of each point inside parentheses: (2.5,14), (2.25,12), and so on, to avoid confusion.
14-12
slope of line thru 1st 2 points is m = ---------------- = 2/0.25 = 8
2.50-2.25
What is the eqn of the line: y = mx + b becomes
14 = (8)(2.5) + b; find b:
14-20 = b = -6. Then, y = 8x - 6.
Now determine whether (12,1.25) lies on this line.
Is 1.25 = 8(12) - 6? Is 1.25 = 90? No. So, unless I've made arithmetic mistakes, (1.25, 5) does not lie on the line thru (2.5,14) and (2.25,12).
Why not work this problem out yourself using my approach as a guide?
