How many solutions does this linear system have y= 1/2x+4 x+2y=-8

Answer:

1 solution

Step-by-step explanation:

y = 1/2x + 4

x + 2y = -8

Solve the second equation for y.

2y = -x - 8

y = -1/2x - 4

The two equations in slope-intercept form are:

y = 1/2x + 4

y = -1/2x - 4

The system consists of two lines with different slopes, so they intercept at a single point which is the solution.

Answer: 1 solution

What is the error in this problem

dlinn [17]

Answer:

10). m∠x = 47°

11). x = 30.96

Step-by-step explanation:

10). By applying Sine rule in the given triangle DEF,

$\frac{\text{SinF}}{\text{DE}}=\frac{\text{SinD}}{\text{EF}}$

$\frac{\text{Sinx}}{7}=\frac{\text{Sin110}}{9}$

Sin(x) = $\frac{7\times (\text{Sin110})}{9}$

Sin(x) = 0.7309

m∠x = $\text{Sin}^{-1}(0.7309)$

m∠x = 46.96°

m∠x ≈ 47°

11). By applying Sine rule in ΔRST,

$\frac{\text{SinR}}{\text{ST}}=\frac{\text{SinT}}{\text{RS}}$

$\frac{\text{Sin120}}{35}=\frac{\text{Sin50}}{x}$

x = $\frac{35\times (\text{Sin50})}{\text{Sin120}}$

x = 30.96
