Answer 1

Answer: D

Explanation:

Area of triangle = [tex]\frac{1}{2} bh[/tex]

b = base lengthh = height

Area of ΔABC =

[tex]\frac{1}{2} CE * AB[/tex][tex]\frac{1}{2} BD * AC[/tex]

Since it's the same triangle, those two areas should equal each other:

[tex]\frac{1}{2} CE*AB=\frac{1}{2} BD*AC\\\frac{1}{2} *9*8=\frac{1}{2} *7*AC\\\frac{1}{2} *72=\frac{7}{2} AC\\36*2=7AC\\AC=\frac{72}{7} =10\frac{2}{7}[/tex]

I hope this is correct

if (x,y) is a solution to the equation 3(x+y)=y what is the value of x over y

Answers

Answer:

-2/3

Explanation:

3(x+y) = y

3x + 3y = y

3x = -2y

x = (-2/3)y

(-2/3)y/y = -2/3

Double check:

x = -2

y = 3

3(-2+3) = 3

3(1) = 3

3=3

[tex]\displaystyle\ 3(x+y)=y \\\\3x+3y=y\\\\ 3x=-2y\\\\\boxed{x=-\frac{2}{3} y \ \ or \ \ y=-1.5x}[/tex]

(root 8)^a = 4^b/3
If a and b are positive numbers in the equation
above, then what is the value of a/b ?

A. 4/9
B. 2/3
C. 3/2
D. 9/4

Answers

Answer:

4/9

Explanation:

√8^a=4^b/3.

You can rewrite √8^a as 8^a/2.

So then that would be, 8^a/2=4^b/3.

If both sides have the same base, we could then make the fractional exponents equal to each other. Since 2^3=8 and 2^2=4, we can make that possible.

2^3(a/2)=2^2(b/3).

2^3a/2=2^2b/3.

 So now 3a/2=2b/3.

Then we isolate the a, by multiplying 2/3 on both sides and are left with:

a=2/3*2/3*b

a=4/9*b

Then you divide both sides by b to get:

a/b=4/9.
