7x+12
8x+3

Because it is a horizontal line the two angles must add up to 180°

So add the two angles up together and set it equal to 180°
7x+12+8x+3=180
Add the two x’s 7x+8x=15x
Add the constants 12+3=15

You get 15x+15=180
Now subtract 15 from both sides
15x=165
Now divide by 15 to get x
X=11

I am Lyosha [343]

Answer:

y = -3x  

Step-by-step explanation:

(a) Slope

y = mx + b

Choose points (-3, 9) and (3, -9)

m = (-9 - 9)/(3 – (-3))

m = -18/(3 + 3)

m = -18/6

m = -3

(b) y-intercept

y = mx +b

Choose point (0,0).

0 = 0 + b

b = 0

=====

(c) Equation of line

y = mx + b

y = -3x

The worth of the bond is $307.50.

<h3>What is the worth of the bond?</h3>

The worth of the bond is the sum of the bond when it was bought and the interest earned on the bond.

Worth of the bond = interest rate + value when the bond was bought

Interest = 105% x $150

1.05 x $150 = $157.70

Worth of the bond = $157.70 + $150 = $307.50
