Answer:
x=0;y=-2
Step-by-step explanation:
multiply first equation by 6: 18x-24y=48
Subtract 2nd equation from 1st: -19y=38
y=-2
Sub into 1st equation: 3x-4(-2)=8
3x+8=8
3x=0
Therefore, x=0;y=-2
Answer:
3^x -2x +14
Step-by-step explanation:
I will assume you mean 3^x in the function f(x)
f(x) = 3^x+ 10
g(x) = 2x - 4
(f - g)(x) = 3^x+ 10 - (2x - 4)
Distribute the minus sign
= 3^x+ 10 - 2x + 4
= 3^x -2x +14
Answer:i cant see it to answer it sorry
Step-by-step explanation:
Refer to the diagram shown below.
The vector has a magnitude of a and a direction of θ degrees south of west.
Use the Pythagorean Theorem to calculate a.
a² = (-530)² + (-200)² = 320900
a = √(320900) = 566.48 mi ≈ 566.5 mi
By definition,
tan θ = (-200)/(-530) = 0.3774
θ = tan⁻¹ 0.3774 = 20.68° ≈ 21°
Answer: about 566.5 mi; 21° south of west.
