Using the inequity -16k-32>-48
Answers
Answer:
k<1
Step-by-step explanation:
1. Add 32 to both sides
-16k-32+32>-48+32
2. Simplify
-16k>-16
3. Reverse the sign (You only reverse the sign if you are DIVIDING BY a negative.)
-16k/-16 = k
-16/-16 = 1
You're left with k < 1
Your number line graph should be an open circle at 1 going to the left.

B.
x + (y + 5) = 6
C.
x = (x – 6) + 5
D.
(y + 5) + y = 6
Answers
(y + 5) + y = 6
shows the substitution method being used to solve the system of linear equations. So the correct option among all the options given in the question is option "D".
For a better explanation, let us first write down the two equations given in the question.
x + 5 = 6
and
x = y + 5
Now the thing that has been done is that the value of x in the first equation has been replaced by the value of x that is given in the second equation. this is actually the substitution method of solving equations.

Option B. 525 students.
Step-by-step explanation:
The school enrollment for Oakwood Elementary is shown in the graph.
The given graph is representing a linear function. So we will form the function first to calculate the enrollment in 2012.
Equation of the given line in the graph will be in the form of y = mx + c
where m is the slope and c = y- intercept
y-intercept = 300
this line passes through two ordered pairs (0, 300) and (1, 325)
Now the slope m =
m =
Therefore, equation representing the situation will be y = 25x + 300
Now we will put the value of x = year 2012 - year 2003 = 9 years
y = 25×9 + 300
y = 225 + 300
y = 525
Option B. 525 is the correct option.

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
