The line contains (9,y) and (-6,3) Then y is 13
<em><u>Solution:</u></em>
Given that a line contains (9, y) and (-6, 3)
Slope of line is 
To find: y
<em><u>The slope of line is given as:</u></em>
<em><u>Substituting the values in formula,</u></em>
Substitute 
2(-6 - 9) = 3(3 - y)
Multiplying the terms with terms inside bracket
-12 - 18 = 9 - 3y
Move the variable to one side
-30 = 9 - 3y
On solving we get,
3y = 30 + 9
3y = 39
Divide both sides by 3, we get
y = 13
Thus y = 13
Answer:
The following are some inequalities that represent the possible position of the playground.
2x ≥ -2 and x < -3
x + 3 ≤ 1 and –x > -3
x + 4 ≤ 2 and x + 4 > 7
2x – 1 ≥ -5 and 3x < 9
The city council planning for playground, that is more than 5 blocks from fountain and at least 2 blocks from center of park.
A solid dot on negative two points less than -2 and a circle dot on positive three points in the direction indicating greater than 3. So the right inequality is x + 3 ≤ 1 and –x > -3. That represents the possible position of ground.
Hence, the inequality x + 3 ≤ 1 and –x > -3 is the playground's possible position.
B + b + b + b + b + 2b = 7b (add all the variables up )
7 x 10 = 70 ( since b = 10 substitute)
Answer:
Solution given:
y=-1/2 x²
for
f(x)=-1/2 x².
differentiating each term with respect to x
f'(x)=-x
when
x=-4
f'(-4)=4>0 increasing
when
x=-2
f'(-2)=2 >0 increasing
when x=0
f'(0)=0 stationary point.
other points are decreasing
so
largest interval of increasing is
A.X<-2
