First you have to combine like terms which you would combine 8j and j which would be 7j+3=17 then subtract 3 from 17 giving you 14. And after that your left with 7j=14 then divide 7 on both sides giving you 2 as your answer.
Answer:
DF = 3 , ∠B = 28° , ∠P = 105° , QR = 11.6 , ∠M=45°,LN = 8.5
Step-by-step explanation:
As ΔABC≅ΔDEF ,
DF = AC and ∠B = ∠E because corresponding parts of congruent triangles are equal.
∴DF = 3 and ∠B= 28°
In the next part,
as ΔLMN≅ΔPQR,
∠P = ∠L , QR = MN , ∠M = ∠Q , LN = PR as corresponding parts of congruent triangles are equal.
∴∠P = 105° , QR = 11.6 , ∠M = 45° , LN = 8.5
Here's how you solve this. So, x+y=2, right? Let's isolate x. x+y-y=2-y. x=2-y. NOW, if x=2-y, in 3x+2y=5, we can REPLACE x with 2-y and use it to solve for y! 3x+2y=5. 3(2-y)+2y=5. (3*2)+(3*-y)+2y=5. 6+(-3y)+2y=5. 6+(-y)=5. 6+(-y)-6=5-6. -y=-1. -y/-1=-1/-1. y=1.
So, if y=1, we can substitute that back into either equation--but let's go with the easier one, x+y=2. x+1=2. x+1-1=2-1. x=1. 1+1=2, so that works; let's check the other equation. 3(1)+2(1)=5. 3+2=5. 5=5. That's correct!
Answer: x=1, y=1
Answer:
D.
Step-by-step explanation:
r = 3
a1 = 2
Our explicit formula is an = a1 (r)^(n-1)
Simply plug in the terms
an = 2(3)^(n-1)
Answer:
Sorry but the correct answer is (x+3)2+(y−1)2=81
Step-by-step explanation:
Because the radius squared is the answer of the equation
