Answer:
The answer to your question is dAB = 10.63
Step-by-step explanation:
Data
A = (7, 3)
B = (-1, -4)
Process
To solve this problem, use the formula of the distance between two points, substitute the values and simplify.
Formula
dAB =
x1 = 7 y1 = 3 x2 = -1 y2 = -4
-Substitution
dAB =
-Simplification
dAB =
dAB =
dAB =
-Result
dAB = 10.63
Explanation:
For the function: x + 4y ≥ 0
Rewrite:
4y ≥ -x
y ≥ -x/4
As the inequality is "≥", the line should be solid.
Dashed line is used for "<" or ">" inequalities.
Points for y = -x/4 are (-4, 1), (0, 0), (4, -1). Use a ruler and graph a solid line through them and shade the portion above the line.
Answer:
Step-by-step explanation:
Let age of each twin be x
let age of sister be s
So we can write:
x + 4 = s
The product of the 3 siblings ages is 3482 more than sum. We can write:
This can be simplified as:
We replace s with "x + 4" and solve:
<u>Note:</u> To solve this cubic, we used technology
Thus, we can say the twins are 14 years old
