-28 < 2x - 10 < -10.....add 10 to all sections
-28 + 10 < 2x - 10 + 10 < -10 + 10....simplify
-18 < 2x < 0...divide all sections by 2
-18/2 < 2/2x < 0/2...simplify
-9 < x < 0 <===

Art [367]

Answer:

y< -3/2x-2

Step-by-step explanation:

if you look at the graph, you can see the line is dotted, which means it is not equal to. eliminate a and c. the shade is toward the bottom of the y, which then you could eliminate a because b says the y value is greater than, which isn't true. you could also check it by plugging in any value for x!

I need answers for them three
sergeinik [125]
These are the answers. You subtract 6 from -3 giving you n≥-9. Since n/3 is a fraction, in order to undo it we must multiply it to the other side, giving us n≤-63.

1. n≥-9
3. n≤-63

I hope it helped!

m∠R = 27.03°

Solution:

Given In ΔQRP, p = 28 km, q = 17 km, r = 15 km

To find the measure of angle R:

Law of cosine formula for ΔQRP:

r^{2}=p^{2}+q^{2}-2 pq \cos R

Substitute the given values in the above formula.

(15)^{2}=(28)^{2}+(17)^{2}-2 (28)(17) \cos R

225=784+289-952 \cos R

225=1073-952 \cos R

Switch the given equation.

1073-952 \cos R=225

Subtract 1073 from both side of the equation.

-952 \cos R=-848

Divide by –952 on both sides.

$ \cos R=\frac{106}{119}

$  R=\cos^{-1} \left(\frac{106}{119}\right)

R=27.03^\circ

Hence m∠R = 27.03°.
