Answer:
there was a -12 integer change
Step-by-step explanation:
-22 + 10 = -12
The answer is c because if you do 7x60 you'll get 420 and 830-420=410 and 7x80 you'll get 560 and 970-560 is also 410.
Answer:
<I= 15degrees
Step-by-step explanation:
Using the cosine rule formulae;
j² = i²+k²-2i cos <J
j² = 37²+57² - 2(37)(57)cos <141
j² = 1369+ 3249- 4218cos <141
j² = 4618- 4218cos <141
j² = 4618-(-3,278)
j²= 7,896
j = √7,896
j = 88.86inches
Next is to get <I
i² = j²+k²-2jk cos <I
37² = 88.86²+57² - 2(88.86)(57)cos <I
1369 = 7,896.0996+ 3249- 10,130.04cos <I
1369 = 11,145.0996 - 10,130.04cos <I
1369 - 11,145.0996 = - 10,130.04cos <I
-9,776.0996=- 10,130.04cos <I
cos <I =9,776.0996 /10,130.04
cos<I = 0.96506
<I = 15.19
<I= 15degrees

Answer:
Step-by-step explanation:
<u>Covert equations in standard form into slope-intercept form of y = mx + b</u>
<h3>#1</h3>
<h3>#2</h3>
- 5x + 3y = 6 ⇒ 3y = -5x + 6 ⇒ y = -5/3x + 2
<h3>#3</h3>
- x - 2y = 2 ⇒ 2y = x - 2 ⇒ y = 1/2x - 1
<h3>#4</h3>
- 3x + 2y = -8 ⇒ 2y = -3x - 8 ⇒ y = -3/2x - 4
