Find the value of x.<br><br> log 3 x = 4<br><br> A.) 7<br> B.) 12<br> C.) 27<br> D.) 81

lakkis [162]

Hello from MrBillDoesMath!

Answer:

Choice D, 81

Discussion:

By log 3x = 4 I presume that "3" is the base not a multiplier of x. Assuming it is the base, then the equation is equivalent to

x = 3^4

= 81

This is Choice D.

Thank you,

MrB

Which of the numbers listed below are solutions to the equation? Check all that apply. x2 = 81 A. 18 B. 40.5 C. -9 D. 162 E. 9 F

Murljashka [212]

X^2 = 81...take the square root of both sides, eliminating the ^2
x = (+-) sqrt 81
x = (+-) 9

answers are : -9 and 9

Write in standard form the equation of a line that is perpendicular to 2x-5y=7 and has the same y- intercept as the line 7x-2y=-

LekaFEV [45]

Answer:

5x + 2y = 9

Step-by-step explanation:

Find the slope of the line that is perpendicular to 2x - 5y = 7 :

m= $\frac{-5}{2}$

Find the y - intercept of the function:

b = $\frac{9}{2}$

substitute m= $\frac{-5}{2}$ and b = $\frac{9}{2}$ into y = mx + b :

y = $\frac{-5x}{2}$ + $\frac{9}{2}$

y = 5x + 2y = 9
