The right answer is option B. 138.7

Step-by-step explanation:

Given function is:

h(x) = 5.7-19x

To find h(-7), we have to put -7 in place of x

h(-7) = 5.7-19(-7)\\= 5.7+133\\=138.7

The value of function at -7 is 138.7.

What is 9y=2x for y I need help with this problem
mojhsa [17]
The first step for finding y is to divide both sides of the equation by 9.
9y ÷ 9 = 2x ÷ 9
When dividing 9 by 9 you must remember that any expression divided by itself equals 1.
y = 2x ÷ 9
Now write 2 ÷ 9 as a fraction.
y = \frac{2}{9}x
This means that the answer to your question is that y = \frac{2}{9}x.
Let me know if you have any further questions.

molecules refer to the smallest particle in a compound or an element, which possesses the chemical properties of that compound or element. They  are also made up of atoms which are held together by chemical bonds as result of exchange or sharing of electrons.
The Formula given in option D is an atom not a molecule because it is not sharing any bond with any other atom.

4.08 rounded to the nearest tenth
madam [21]
Hello!!!! 

Rounding becomes really easy if you know your places!
So, if you want to round 4.08 to the nearest tenth, all you would have to do is find the tenth place, in this case, the 8.
Since 8 is above 5, you can automatically round to 10.
So, your answer would be 5!
Hope I helped you!!!!! :)

Alja [10]

​Answer:

14.29cm

Step-by-step explanation:

Height of the building=10cm

Angle of depression=60°

We are therefore asked to find the distance from the stone to the

the foot of the building;Therefore we use Tan ratio which is opp/adj;

Let the distance from the stone to the foot of the building be x;

10/x=Tan60°

10/x=1.7/1

We then cross multiply to get 1.7x=10

x=10/1.7

=10*10/1.7*10

=100/17

=14.29cm.
