log (sqrt(xy))/z is equal to
a) 1/2 logx + 1/2 logy - logz
b) 1/2 logx + logy - logz
c) 1/2 (logx + logy - logz)
d) 1/2 log xy/ logz
Answer:
A) [tex]\frac{1}{2}log(x)+\frac{1}{2}log( y)-log(z)[/tex]
Step-by-step explanation:
[tex]log\frac{\sqrt{xy}}{z}[/tex]
[tex]log\sqrt{xy}-log(z)[/tex]
[tex]log(xy)^\frac{1}{2}-log(z)[/tex]
[tex]\frac{1}{2}log(xy)-log(z)[/tex]
[tex]\frac{1}{2}(log(x)+log(y))-log(z)[/tex]
[tex]\frac{1}{2}log(x)+\frac{1}{2}log( y)-log(z)[/tex]
Therefore, A is correct

Find the image of NPQ under the translation of (x, y) + (x + 8, y + 1).
АВС
DEF
KLM
GHJ
Answer:
Triangle KLM
Step-by-step explanation:
Firstly, we need to write the coordinates of triangle NPQ
We have this as;
(-7,-6) for N
(-4,-3) for P
(-4,-6) for Q
Now, we are going to use the given translation formula;
(x + 8, y + 1)
N’ will be (-7+ 8, -6 + 1) = (1,-5)
P’ will be (-4+ 8, -3+1) = (4,-2)
Q’ will be (-4+ 8, -6+1) = (4,-5)
Now, we need to find the triangle with the exact given transformation coordinates calculated above;
We have the triangle as;
KLM
With K as (1,-5) ; L as (4,-2) and ; M as (4,-5)

Emma read the statement “the quotient of six and a number, x, is the same as negative two times the difference of x and 4.5.” She translated it as shown below.
6 x = negative 2 x minus 4.5
What errors did Emma make? Select two options.
She should have used division to represent the quotient of six and x.
She should not have included an equal sign.
She should have used parentheses to show that Negative 2 is multiplied by (x minus 4.5).
She should have subtracted the difference (x minus 4.5) from Negative 2.
She should have used parentheses to show that Negative 2 is multiplied by (4.5 minus x).
The errors Emma made from her translation are;
She should have used division to represent the quotient of six and x.She should have used parentheses to show that Negative 2 is multiplied by (4.5 minus x).The correct answer choice is option A and E
What errors did Emma make?quotient of six and a number, x, is the same as negative two times the difference of x and 4.5
6/x = -2 × (4.5 - x)
6/x = -2(4.5 - x)
Ultimately, Emma should have translated the statement in the form 6/x = -2(4.5 - x).

this equation in slope/y-intercept form in the blank
Answer:
y=-9x+6
Step-by-step explanation:
y-y1=m(x-x1)
y-(-3)=-9(x-1)
y+3=-9(x-1)
y=-9x+9-3
y=-9x+6
What is the slope of the line represented by the equation y = -2/3 - 5x
Answer:
-5
Step-by-step explanation:
equation of a line is y=m*x+b
m is the slope of that line
so for y= -5x -2/3 m would be -5
Answer:
The slope intercept form of a line takes the Form
y= mx + c
where M is the gradient and as you can see... Its the coefficient of "x"
From the equation given
y= -2/3 - 5x
The Slope(gradient) is -5.

in what ratio we increase 900 to get 1200
Answer:
4:3
Step-by-step explanation:
Let's say that the number we multiply to get to 1200 from 900 is x.
900x=1200
Now, we divide both sides by 900:
x=1200/900
x=4/3
The number is 4/3. In ratio form, this is 4:3
Answer:
3 : 4
Step-by-step explanation:
900 : 1200
= 30 x 30 : 30 x 40
= 30 : 40
= 3 x 10 : 4 x 10
= 3 : 4
