2 answers:

5 0

3(x – 4) ≥ 5x + 2

3*x - 3*4 ≥ 5x + 2

3x - 12 ≥ 5x + 2

3x - 5x ≥ 2 + 12

-2x ≥ 14

x ≤ 14 / -2 When dividing by a -ve number the sign reverses.

x ≤ -7

3(x-4) $\geq 5x+2$
Opening brackets;
3x-12 $\geq$ 5x+2
Putting like terms together;
3x-5x $\geq 2+12$
-2x $\geq 14$
x $\leq -7$

vova2212 [387]

(x + 9) multiplied 5 = 110. kim is 13 years old, so Jordan is 22. d < - 14. for the graph solution you draw a sign on the line and write under the sign - 14 and then you draw another line that starts from - 14 and goes to the left, so that means that d < - 14.

Steam and leaf plot help!!!! picture down below

Diano4ka-milaya [45]

I would say that the correct answer is C because if you look up on the chart thing, it tells you how you would see the graph. For example, when you have:

1| 03145
2| 4 6 3 7

Which one has the most value to it? It would be the 2| 4 6 3 7, because when you put them together, it makes 24, 26, 23, 27. Hope this helps.

(Two office buildings are 51 m apart. The height of the taller building is 207 m. The angle of depression from the top of the ta

Sholpan [36]

See the attached figure to better understand the problem

we know that

in the triangle ABC
tan 15=AC/BC--------> AC=BC*tan 15
BC=51 m
AC=51*tan 15------> AC=13.67 m

the height of the shorter building=207-AC----> 207-13.67----> 193.33 m
the height of the shorter building=193 m

the answer Part a) is
the height of the shorter building is 193 m

Part b) how does the angle of depression from the top of the taller building relate to the angle of elevation from the top of the shorter building

we know that

the angle of depression is equals to the angle of elevation
so

the answers are
A:They are congruent
D:They are alternate interior angles
