Step-by-step explanation:
Y=90° as its a right angled triangle
Answer:
x = -9 ; x = 7
Step-by-step explanation:
We have to find two numbers whose product is -63 and whose sum is 2
the two numbers are 9 and -7
(x+9)(x-7) = 0
x = -9
x = 7
Answer:
Hey there!
This can be modelled by an equation, y=2x+3.25
For one mile: y=2(1)+3.25, or y=5.25
For twenty miles: y=2(20)+3.25, or y=43.25
Hope this helps :)
Yes they represent a function
You can approach this question by writing the function as y=… as I did in the photo. Then rearrange to make x the subject. Lastly, swap the ys for xs and write as I did on the final line of my working. If you like I can explain how to rearrange the equation or answer any other questions but I think you should be able to see
