Answer:
Step-by-step explanation:
Answer:
a1 =0
a2 = -8
a3 = -16
a4 = -24
a5 = -32
a6 = -40
Step-by-step explanation:
a1 =0
an = an-1 -8
We subtract 8 each time
a1 =0
a2 = 0-8 = -8
a3 = -8 -8 = -16
a4 = -16 -8 = -24
a5 = -24-8 = -32
a6 = -32-8 = -40
Answer:
y = -3
Step-by-step explanation:
9x + 7y = -12
Let x = 1
9 (1) + 7y = -12
9 + 7y = -12
Subtract 9 from each side
9 -9 + 7y = -12-9
7y = -21
Divide each side by 7
7y/7 = -21/7
y = -3
Answer:
y = -3
Step-by-step explanation:
9x + 7y = -12
9(1) + 7y = -12
9 + 7y = -12
7y = -12 - 9
7y = -21 (divide both sides by 7)
y = -3
Answer: 44
Step-by-step explanation:
we will find RN and NQ, then add together to give us RQ.
To find RN;
RP= 17 PN = 15 and RN =?
using pythagoras theorem,
adj^2 = hyp^2 - opp^2
RN^2 = RP^2 - PN^2
?^2 = 17^2 - 15^2
?^2 = 17^2 - 15^2
?^2 = 289 - 225
?^2 = 64
? = √64
? = 8
RN=8
To find NQ,
PN = 15 PQ=39 and NQ=?
using pythagoras theorem
NQ^2 = PQ^2 - PN^2
?^2 = 39^2 - 15^2
?^2 = 1521 - 225
?^2 = 1296
? = √1296
? = 36
NQ= 36
RQ = RN + NQ
RQ= 8 + 36
RQ=44
