I REALLY NEED HELP!!! If someone can answer this quickly and correctly I will give them Brainliest. 1. What is the function rule
Rainbow [258]

Answer:

y= -4x + 3

Step-by-step explanation:

Because the slope is -4/1 which is the same as 4 and 3 is the y-intercept.

Here's the work;

We can just use the first two coordinates which are (0,3) and (1,-1) to get from the x-value 0 to 1 we add 1. and to get from the y-value 3 to -1 we subtract 4. Therefore the slope is -4 and the y- intercept (when x is zero) is 3. Pop that into slope intercept form to get y=-4x +3

Hope that helps and have a great day!

PLEASE HELP ASAP WITH MATH QUESTION<br> WHAT IS (-image down below-) EQUAL TO?????
PolarNik [594]

Answer:

1364

Step-by-step explanation:

∑ means that to add values

So n goes from 1 to 5 and you have to add them from 1 to 5

∑n=1 to 5 4^n = 4^1 + 4^2 + 4^3 + 4^4 + 4^5

4^n means that 4 is n times if 4^3 its mean that 4 is 3 times

= 4 + 16 + 64 + 256 + 1024

= 1364 Answer


I hope you got the idea. Thanks
