Answer:
b = 1
Step-by-step explanation:
-18+4b=7(4)+(7)-(6b)
-18+4b= 28 + (-42b)
4b-16=-42b+28
Add 42b to both sides.
4b-16+42b=-42b+28+42b
46b-18=28
Add 18 to both sides.
46b-18+18=28+18
46b=46
b= 46/46
b=1

Convert 3x-y+2=0 in rectangle form to polar form
Answer:
r ( 3cosθ - sinθ) = -2
Step-by-step explanation:
The equation so given is already in rectangular form, the task is to convert it to polar form.
3x - y + 2 = 0
To transform an equation from the rectangular to the polar coordinate:
x = r cosθ
y = r sinθ
Substitute the representations for x and y into the given equation:
3(r cosθ) - (r sinθ) + 2 = 0
3rcosθ - rsinθ = -2
The polar representation of the equation then becomes:
r ( 3cosθ - sinθ) = -2
Answer:
Isolate the variable by dividing each side by factors that don't contain the variable.

66.666666 repeated decimal
You would keep the 66 as is, and divide 2 by 3. That equals 0.66666666666 repeated, so the answer would be 66.666666 (rounded: 66.67)
Answer:
Possible
Step-by-step explanation:
The rule for triangle side lengths is that the two shortest sides must add up to the longest side so it is possible because
3+7 = 10
Two short sides = The longest side
