Part A,
I would assume the triangles are similar so
6y=4y+18
minus 4y both sides
2y=18
divide 2
y=9

Part B
sub for y
6(9)=54
the angle is 54

4. I actually forgot proofs, let me think
dunno this one
I would say cory is wrong



3rd attachment
5. since 8≠9, it is not a bisector of any sort nor is it equidistant from T and R
answer is point A is not on a bisector


4th attachment
it is not perpendicular in any way
if we assume that TXA=RXA, then the first and last options are right


5th attachment
7.
those 2 triangles are equal because of Side-angle-side
they have to be equal 2x=3x-5
minus 2x both sides
0=x-5
add 5
5=x
x=5

8.
it would be isocelseese
because the 2 sides are equal

Which scenario is modeled by the equation (x)(0.6) = $86.46?
belka [17]

Answer: A picnic table is on sale for 60 percent off. The original price of the picnic table is x, $144.10.


Step-by-step explanation:

Given equation: (x)(0.6)=\$86.46

To find x, divide 0.6 on both sides, we get

x=\frac{\$86.46}{0.6}\\\Rightarrow\ x=\frac{\$864.6}{6}\\\Rightarrow\ x=\$144.10

Also 0.6=0.6\times100=60\%

Thus, 60\%\ of\ \$144.10=\$86.46

So the best scenario modeled by the above equation is

"A picnic table is on sale for 60 percent off. The original price of the picnic table is x, $144.10."

Use the zero product property to find the solutions to the equation x2 – 15x – 100 = 0.
IrinaK [193]

Answer:

x= 20      x =-5

Step-by-step explanation:

x^2 – 15x – 100 = 0.

What two numbers multiply to -100 and add to -15

-20 * 5 = -100

-20 +5 = -15

(x-20) (x+5) =0

Using the zero product property

x-20 =0     x+5 = 0

x= 20      x =-5
