Answer:
is this even real math ?
Step-by-step explanation:
Answer:
Put a point at (-7,0) and another at (0,-2)
Step-by-step explanation:
2x+7y=-14
Plug in 0
2(0)+7y= -14
7y=-14
y=-2
same thing for x
2x+7(0)=-14
x=-7
Answer:
True
Step-by-step explanation:
3k-14=3(k-5)+1
3k-14=3k-15+1
3k-3k=14-15+1
0=14-15+1
-14=-15+1
-14=-14
Answer:
Step-by-step explanation:
There are a lot of typos in the question, so I can't choose the correct answer.
First magnitude...
d^2=5^2+3^2
d^2=25+9
d^2=34
d=√34
now for direction...
tanα=y/x
α=arctan(y/x) and we know y=5 and x=3 so
α=arctan(5/3)
α≈59.03624
So the vector of her ride is:
√34, 59.03624° or if you prefer...
√34, 59°2'10" (in standard angle position)
