Looks like all you have to do is to translate this expression into symbols:
2.1*10^9
Answer:
The y intercept is -21
Step-by-step explanation:
y = (x - 3)(x + 7)
To find the y intercept, set x =0 and solve for y
y = (0-3) (x+7)
y = -3*7
y = -21
The y intercept is -21
Answer:
3x+4y=36
x=0, then 4y=36
from there you would divide 36 by 4(y) and y=9
and if y=0, then 3x=36
from there you would divide 36 by 3(x) and x=12
ANSWER: (12,0) (0,9)
Hope this helped! :) <3
