Write the standard form of the equation of the line described: through: (2,0), parallel to y=2/3x
podryga [215]
Parallel line has equal slopes, hence required line has slope of 2/3.
Required equation is y - 0 = 2/3(x - 2)
y = 2/3 x - 4/3
2/3x - y - 4/3 = 0
2x - 3y - 4 = 0

How do you solve this as a solution 9(2 + 3x) < 72
laila [671]

Answer:

x <2

Step-by-step explanation:

9(2 + 3x) < 72

Divide each side by 9

9/9 *(2 + 3x) < 72/9

2+3x < 8

Subtract 2 from each side

2+3x-2 < 8-2

3x<6

Divide each side by 3

3x/3 <6/3

x <2

Simplify completely the quantity 5 times x to the third power plus 10 times x to the 2nd power plus 15 times x all over 5 times
Novay_Z [31]
You would factor a 5x out of the numerator sine there is a 5x in 5x^3, 10x^2 and 15x. when you factor, it should be 5x( x^2+2x+3). The 5x on top and bottom would then cancel out, leaving x^2+2x+3 as you answer.
