Answer:
r = - 3
Step-by-step explanation:
To find the common ratio r, divide consecutive terms
- 9 ÷ 3 = - 3
27 ÷ - 9 = - 3
- 81 ÷ 27 = - 3
Thus common ratio = - 3
Answer:
18
Step-by-step explanation:
⅓g + 6 = 12
⅓g = 6 Subtracted 6 from each side
g = 18 Multiplied each side by 3
18 games remain in the season.
Check:
⅓ × 18 + 6 = 12
6 + 6 = 12
12 = 12
Answer: x = 17.2
Step-by-step explanation:
So we can combine 8.7x and 1.9x as they are considered like terms.
So basically since they have the same base of x we can disregard the x when subtracting.
So its more like 8.7-1.9 which = 6.8
Now add the x back
So it is 6.8x = 116.96
Now we need to isolate the variable.
To do this we need to divide the 6.8 on both sides.
So x = 116.96/6.8
x = 17.2
Hello
<span>an equation for the line in point-slope form and general form is :
y = ax+b a : </span>slope ; the <span>Passing through (x' ; y')
</span>y' = ax'+b
y-y' =a(x-x') and : x' =8 y' = -4
calculate a :
let : y = ax+b .....(D)
....(D') y = (1/5)x+4
.(D) perpendicular to(D') : slope (D) × slope (D') = -1
slope (D') = 1/5
slop(D)×(1/5) = -1
slope (D) = -5
equation for the line : y-y' =a(x-x')
y+4 =(-5) (x-8)
