Your word equation can be rewritten as X-4 > 15. to solve, add the 4 to both sides, which leaves you with X > 19. To check it, you can plug in different numbers for X to see if X indeed needs to be less than 19 to make your equation true. Hope this helps!

Answer:

∠ YZX ≈ 19.7°

Step-by-step explanation:

using the sine ratio in the right triangle.

sin YZX = \frac{opposite}{hypotenuse} = \frac{XY}{YZ} = \frac{7.5}{22.3} , then

∠ YZX = sin^{-1} ( \frac{7.5}{22.3} ) ≈ 19.7° ( to 3 significant figures )

noname [10]

Answer:  log_39=2 is the logarithmic equation which is equivalent to3^2=9.


Step-by-step explanation:

According to the laws of logarithms

log_b\ x=n ,where b=base ,n,x all are positive

It can be written in exponential form such as

x=b^n

Now in the given question x=9 ,b=3 and n=2 such that it will equals to

log_39=2

Hence the logarithmic equation for 3^2=9 islog_39=2.

How to find the zeros of f(x)=5(2x-5)(5x+4)
Elenna [48]
If xy=0 we assume x and y equal 0

so

the zeros are wehre f(x)=0
0=5(2x-5)(5x+4)
set each to zero
5 is not equal 0 so we don't do that

0=2x-5
5=2x
5/2=x

0=5x+4
-4=5x
-4/5=x

zeroes at x=5/2 and -4/5
