Answer:
w=+/-4.24 or whatever could be either since its squared
Step-by-step explanation:
subtract 25 so 5x^2=90. divide by 5 so w^2=18 then square root to get rid of the ^2 so w=+/-4.24
Answer:
21 3/4
Step-by-step explanation:
3 times 7 1/4 since the scale is 1:7 1/4. Good luck!! :)
Answer:
a.)x = negative 4 y + 19
Step-by-step explanation:
i got it right on e2020 lol
Step-by-step explanation:
Two lines that are perpendicular to each other has -1 as the product of thir gradient.
Since the gradient of the line y = 3 - x is -1, the gradient of the other line must be 1.
So y = x + c.
When x = 7, y = 1. 1 = 7 + c, c = -6.
Hence the equation of the line is y = x - 6.
Answer: x>-1
Step-by-step explanation: I know this because I solved this equation. I know that is not a good explanation but I know it is right.
