Which equation is in point-slope form for the given point and slope?
grin007 [14]
The equation of a straight line is y=mx+b, where m is the slope of the line.
By substituting the given information into this equation, we get:
7=(2/3×1)+b 
Now solve to find b, the y intercept:
7=2/3+b
b=19/3
So the equation of the line is y=2/3x+19/3

Hm uh I dont get it help ?????..........
Angelina_Jolie [31]

Answer: A, D

Step-by-step explanation:

We know that the volume of a cone is V=\frac{1}{3} \pi r^{2} h, so we want to keep r^{2}hconstant.

A: r^{2}h=6^{2} \cdot 3=108

B: r^{2}h=5^{2} \cdot 6=150

C: r^{2}h=4^{2} \cdot 9=144

D: r^{2}h=3^{2} \cdot 12=108

Please i need to know if im correct with these questions
telo118 [61]

Answer: No Solution

<u>Step-by-step explanation:</u>

ln x - ln (x + 2) = 4             restrictions: x > 0  and  x + 2 > 0   →    x > 0

ln (\frac{x}{x + 2}) = 4

(\frac{x}{x + 2}) = e⁴

x = e⁴ (x + 2)

x = 54.5982 (x + 2)

x = 54.5982x + 109.1964

- 53.5982x = 109.1964

x = \frac{109.1964}{-53.5982}

x = -2.0373

-2.0373 is not greater than 0 so is not valid

**************************************************************************

Answer: 2.1972

<u>Step-by-step explanation:</u>

eˣ = 9

ln eˣ = ln 9

   x = ln 9

   x ≈ 2.1972

**************************************************************************

Answer: \frac{3}{2}

<u>Step-by-step explanation:</u>

log₂ (3x - 4) = -1

        3x - 4 = 2⁻¹

         3x - 4 = \frac{1}{2}

       <u>       +4 </u>   <u>+4 </u>

          3x     = 4\frac{1}{2}

          3x     = \frac{9}{2}

          \frac{3x}{3} = \frac{9}{2} * \frac{1}{3}

            x = \frac{3}{2}

**************************************************************************

Answer: 1.117519

<u>Step-by-step explanation:</u>

in the calculator, type in 1 ÷ 9.

Then hit the eˣ button.

 e¹⁾⁹

= e°¹¹¹¹¹¹

= 1.117519

rounded to 6 decimal places: 1.117519
