- Three people examine the system of linear equations shown.

1 answer:

4 0

Answer:

there are no solutions as the two straight lines represented by the two equations are parallel, so they have no point in common

Step-by-step explanation:

general equation of a straight line: ax + by + c = 0

the slope (or raise) of a straight line m is equal to -a/b (b=1 a=-2 in this exercise as the equation is 1y=-2x - 4)

so m1 = -2/1 = -1/2

and m2 = -2/1 = -1/2

there is also a geometrical explanation, but I am not sure if it could be too complex

BigorU [14]

Answer:

r = 11.623cm (aprox)

n = 6.153cm (aprox)

Step-by-step explanation:

Proportions:

9.8 ⇔ 4.3

n ⇔ 2.7

r ⇔ 5.1

n = 9.8*2.7/4.3 = 6.153 (aprox)

r = 9.8*5.1/4.3

r = 11.623 (aprox)

What is X and how do I find it??

rjkz [21]

Answer:

x ≈ 10.92

Step-by-step explanation:

Using the sine ratio in the right triangle

sin83° = $\frac{opposite}{hypotenuse}$ = $\frac{x}{11}$

Multiply both sides by 11

11 × sin83° = x, thus

x ≈ 10.92 ( to 2 dec. places )
