Since 9 times 8 is 72, and 7200 is close to that number, a proper estimate would be 800.
Answer:
5)
<2 = 79°
<1 = 101°
<3 = 101°
6)
x = 5
y = 3
Step-by-step explanation:
5)
<2 = 79°
<1 = <3 = 180 - 79 = 101°
6)
4y - 6 = 2y
2y = 6
y = 3
2x + 4 = x + 9
x = 5
Answer:
4

Step-by-step explanation:
Answer:
y = 5x + 12
Step-by-step explanation:
Use the formula: y - y1 = m(x - x1)
Plug in all numbers into your equation: y - 7 = 5(x - -1)
Minus with a minus becomes a positive: y - 7 = 5(x + 1)
Distribute: y - 7 = 5x + 5
Add 7 to both sides: +7 +7
Answer: y = 5x + 12
