Answer is B
Step-by-step explanation:
You have the side opposite the angle and the Hypotenuse so use soh
Sine(x) = opposite/Hypotenuse
Sine(x) = 9/19
X = sin-1(9/19) - - - - - here the - 1 is to the power of
X= 28,27371363
X= 23,3
Answer:
Lien: $26300 Her husband: $24700
Step-by-step explanation:
x+(x+1600)=51000
2x+1600=51000
2x=49400
x=24700
Her husband earned 24700
24700+1600=26300
Lien earned 26300
The length of the rectangle would be 21
Proportion to set it up would be 7/3 x X/9 cross multiply and solve for x which is 21

Step-by-step explanation:
Answer:
y = 2x + 1 --> linear
y = -4x + 7 --> non-linear
Not a solution for a linear system.
Step-by-step explanation:
for (a), y = 2x+1, substitute the x and y values. keep in mind, that in a linear pair, (x, y). So, for the first equation you get:
7 = 2x3 + 1. This is correct, because 6 + 1 is 7. Therefore, (a) is linear.
for (b), we have to substitute our values again. You get:
7 = -4x3 + 7, which is
7 = -12+7, which is not true. So, (b) is not linear.
This means that for the linear pair (3, 7), it does not satisfy both equations, which means that it is not a solution for the linear system.
