Steps:
1. Substitute the y in 4x + 10 with -5x-10
-5x-10= 4x + 10
2. Add 5x on both sides
-10= 9x + 10
3. Subtract 10 on both sides
-20= 9x
4. Divide by 9 on both sides
5. Your answer is
X= -20/9
Answer:
Step-by-step explanation:
Now we know that
sec²θ -tan² θ= 1 ,
So tan²θ =sec²θ - 1
So the left of the given equation will be
sec²20 + sec²40 +sec²80 - 3
So
1/cos²20+1/cos²49+1/cos²80 -3
Remember sec θ= 1/cosθ
So
= since secθ = 1/cosθ
we have
= 1.1324 + 1.7040 + 33.1634 - 3
= 35.9998 - 3
= 33
The question is incorrect
the correct question is
A local citizen wants to fence a rectangular community garden. The length of the garden should be at least 110 ft,and the distance around should be no more than 380 ft. Write a system of inequality that model the possible dimensions of he garden. Graph the system to show all possible solutionslet
x---------------> t<span>he length of the garden
</span>y---------------> the wide of the garden
we know that
x>=110
2x+2y <=380---------------> x+y <= 190
Part A) <span>Write a system of inequality that model the possible dimensions of he garden
</span>
the answer part A) is
x>=110
x+y <= 190
Part B) <span>Graph the system to show all possible solutions
using a graph tool
see the attached figure
the solution is the triangle show in the figure
</span><span>the possible solutions of y (wide) would be between 0 and 80 ft
</span>the possible solutions of x (length) would be between 110 ft and 190 ft
Answer: 2/3

(1/3)*X = 2-((2/5)*X)
t = (S/5)*r^2
1*x^3+3*x+0*x^2+4 = 0
g-(1/3) = 2/3
Answer:
x=2
Step-by-step explanation:
14x+3=31
Step 1: Subtract 3 from both sides.
14x+3−3=31−3
14x=28
Step 2: Divide both sides by 14.
14x/14=28/14
x=2
