Do you still need help?!?
Answer:
280
Step-by-step explanation:
first make a proportion. 7 over 250= x over 10,000. cross multiply to get 250x=70,000. 70,000 divided by 250 which gets you 280.
Answer:
x = - 2
Step-by-step explanation:
y = 4 is the equation of a horizontal line parallel to the x- axis.
Thus a perpendicular line will be vertical and parallel to the y- axis.
The equation of a vertical line is
x = c
where c is the value of the x- coordinates the line passes through.
The line passes through (- 2, 1) with x- coordinate - 2, thus
x = - 2 ← equation of perpendicular line
80 million would be the answer
