Answer:

Graph the equations

Step-by-step explanation:

x - y = 1

3x + 2y = - 12

Rewrite equations into y=mx+b form:

y = -1 + x

y = -6 - 1.5x

Graph it!

Hypotenuse = 45
Angle = 63
Height = h

To find h, use the sine of 63:

sin 63 = h/45

0.891 = h/45

h = 45 × 0.891

h = 40.095 feet

To the nearest tenth, 40.1 feet.

Hope this helps!

Ksju [112]
Jason is buying 2 hats and 3 scarves for each of his 4 children

so he is actually buying 8 hats and 12 scarves.

a hat costs 8.50 and a scarf costs 5.50

so you put it into a equation

8.50(h)+5.50(s) = P     h = hat, s = scarf, P = pay

8.50(8)+5.50(12) = P

68 + 66 = P

P = 134

hope this helps
