Answer:
The coordinates are ( 4, -3).
Step-by-step explanation:
We can find the coordinates by solving the 2 equations
y = 1/4x-4
y = -1/2x-1
As both left sides of the equation are y we can say:
-1/2x-1 = 1/4x-4
-1/2x - 1/4x = -4 + 1
-3/4 x = -3
x = -3 * -4/3
x = 4.
- and y = 1/4(4) - 4 = -3.
Answer:
The answer to your question is: d) 0.46x10^-4
Step-by-step explanation:
(1.15x10⁻⁷) / (2.5x10⁻³)
First, divide 1.15 by 2.5 1.15 / 2.5 = 0.46
Second, subtract the power -7 - (-3) = -7 + 3 = -4
Finally, express the number 0.46 x 10⁻⁴
a) 4.6x10^-10
b) 0.46x10^-3
c) 4.6x10^-3
d) 0.46x10^-4
Answer:
