3.5x-10>-3 add 10 to both sides
3.5x>13 divide both sides by 3.5
x>26/7
x=(26/7, +oo)
...
8x-9<39 add 9 to both sides
8x<48 divide both sides by 8
x<6
x=(-oo,6)
Since this is a compound inequality with AND the solution set will be the union of the two intervals found above.
x=(26/7, 6)
Answer:
To find the perimeter of this triangle, we add up all the sides together.
(8 · √3) + (8 · √3) + √384
But before we add them, let's simplify them.
(8 · 1.7) + (8 · 1.7) + 19.6
13.6 + 13.6 + 19.6
27.2 + 19.6
= <u>46.8</u>, is the perimeter of this triangle.
Now to find the area, we use the formula:
(formula for area of a triangle)
A = BH · 1/2
Where 'B' represents the base, 'H' stands for the height, and 1/2 means that you divide the product of the base and height by 2.
<u><em>What we know:</em></u>
- Base = 8 · √3 which equals <u>13.6</u>.
- Height = 8 · √3 which equals <u>13.6</u>.
Plug in the values into our formula:-
A = BH · 1/2
A = 13.6(13.6) · 1/2
A = 184.96 · 1/2
A = 184.96/2
A = <u>92.48</u>, is the area for this triangle.
Answer:
y = -4/3x -9
Step-by-step explanation:
Slope intercept form is
y = mx+b where m is the slope and b is the y intercept
8x+6y = -54
Subtract 8x from each side
8x+6y-8x = -8x-54
6y = -8x-54
Divide each side by 6
6y/6 = -8x/6 -54/6
y = -4/3x -9
