Hello :
<span> |6x + 7| ≥ −3 is right (true) for all reals : x because </span><span> |6x + 7| ≥ 0
</span><span>the set solution is : R
</span>in interval notation : ]-∞,+∞[
Answer:
1/2×4×3 =6
Step-by-step explanation:
The 1/2 will multiply the 4×3 which is 12
So therefore the answer is 1/2×6
when u reduce it u will get 6 as the answer
Answer:
32
hope this helps
have a good day :)
Step-by-step explanation:
First step to solve (v+6)(v-6)=0 is to use FOIL and dd the multiplication
v^2-6v+6v-36=0
v^2-36=0\ or v^2=36
we need to take the square root from both sides so
v=6 and v=-6
<span>v = {-6, 6}</span>
X = 0
<span>6y - 5x = 0 so it intersects x=0 at (0,0)
</span>
<span>x + 3y = 21
</span>so it intersect x=0 at (0,7)
multiply by 2
<span>2x + 6y = 42
subtracting 6y - 5x = 0
7x = 42
x = 6
so the third line intersects w second line at (6,5)
6. area of triangle = 1/2*base*height
= 1/2*7*6
=21
7. volume = volume of 2 cones
cone volume = 1/3*pi*radius^2*height
lower cone: radius=6, height=5
upper cone: radius=6, height=7-5=2
volume = 1/3*pi*6^2*(5+2)
=84pi
=263.89
