Answer:

- 1

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - x - \frac{40}{17} ← is in slope- intercept form

with slope m = - 1

Parallel lines have equal slopes

Thus the slope of line d is - 1

9× 3 1/2=<br> Which choice is the most reasonable answer?
icang [17]

Answer:

31.5 or 63/2

Step-by-step explanation:

to do this, first you need to transform the <u>mixed number</u> <em>(3 1/2)</em> into an <u>improper fraction</u>, to get 7/2.

then you just multiply 9 by 7/2

9/1 (7/2)

63/2 = 31.5

<em>both of the answers in bold are correct</em>

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°.
