B. Isosceles. that is the correct answer
Answer:
(j+1)(2) is simplified into (2j+2)
Step-by-step explanation:
Multiply both parts of the equation by 2 to get your answer.
We will prove first that PRQ≡PSQ
We need 3 attributes from the each triangle:
QS=QR
PR=PS
PQ=PQ
from PRQ≡PSQ => angles RPQ and SPQ are equal
Let if be O=RS∩PQ
We will prove that triangles RPO≡SPO
We need 3 attributes from the each triangle:
RP=PS
PO=PO
angles RPQ and SPQ are equal
results that angles RPO and SPO are equal(Let's note them with x)
We also know that (as angles) POS≡ROS and POR≡SOQ as opposite angles
We now have than 4x=360 wich means x=90. And we proved the desired result.
You just need to put this explanation into the table. (most if the 3 attributes for each triangle)
Answer: the answer to this question is a triangle.
Step-by-step explanation:
If you sliced the pyramid to the base there would still be a triangle left.
Answer:
Step-by-step explanation:
I think the below is your full question:
<em>Mike makes seven dollars an hour working at the grocery store and $10 an hour delivering newspapers. He cannot work more than 20 hours per week. Graph two inequalities that Kishi can use to determine how many hours he needs to work at each job if she wants to earn at least $90 per week.</em>
Here is my answer:
Let x is the number of hours he works at the grocery store
Let y is the number of hours he works at the newspapers
We have two inequalities:
1/ x + y 
<=> y 
20 - x
2/ 7x + 10y 
<=> y 
3/4x + 12.5
Please look at the attached photo
The red line is y 20 - x
The blue line is: y 3/4x + 12.5
