4)
Area=(base x height) / 2
area=24 in²
therefore:
(b*3b)/2=24 in²
3b²/2=24 in²
b²=(24*2)/3 in²
b²=16 in²
b=√(16 in²)= 4 in
answer: 4 in
5)
if x=9
x²+z=103
(9)²+z=103
81+z=103
z=103-81=22
if x=-9
(-9)²+z=103
81+z=103
z=103-81=22
Answer: 23
1)
n²-49=0
n²=49
n=⁺₋√49=⁺₋7
Answer: ⁺₋7
2)
x²+64=0
x²=-64
x²=⁺₋√-64 These numbers are not real.
Answer:no solution
3)
area=slide²
slide=+√area
slide=+√(144x²)=12x
answer: 12 x
Answer: 192 is the answer
Step-by-step explanation:
|-3 x 64|
3x4 is 12 then you add the one above the 6
next you do 3x60+1 and you get 190 so then you add the 2 that was left over to get 192 as your answer
Answer:
b is the inequality this number line represent
The point (-2, 5) is not included in the solution area
<h3>The graph of the inequalities</h3>
The system of inequalities is given as:
y > 5x + 5
y > -2x+1
See attachment for the graph.
Since the inequalities use the greater than symbol, then the lines of the inequalities would be a dotted line and the upper part would be shaded
<h3>The solution area</h3>
The point is given as:
(-2, 5)
The point (-2, 5) is not in the shaded area of the system of inequalities
Hence, the point is not included in the solution area
Mathematically, we have:
5 > 5 * -2 + 5 ⇒ 5 > -5 --- true
5 > -2 * -2 +1 ⇒ 5 > 5 --- false
Since both inequalities are not true, then the point is justified
