Answer:
h(-4) = -2
Step-by-step explanation:
h(x)=-2x-10
Let x = -4
h(-4)=-2*-4-10
=8-10
= -2
The equation would be a-44=64÷4

and 
Step-by-step explanation:
Given
See attachment
Required
Identify the vertical angles
Keynotes
- Vertical angles opposite one another
- Vertical angles are equal to one another
Using the keynote as a reference, we have the following observation from the attachment:
and
are opposite
and
are congruent
Hence:
and
are vertical
<em>(d) is correct</em>
To solve, first let’s define regrouping:<span>
<span>=> Regrouping involves carrying and borrowing during subtraction and addition of the given numbers.
So let us have the non-regrouping decimal number:
=> 8.4
Next, the other regrouping decimal
=> 5.7
So now let us show how it becomes 14.1:
8.4
+5.7
14.1
Starting from the right, 4 + 7 is equal 11, so bring down 1 and carry 1. Now 8+5 = 13, but 13 + carry 1 = 14
<span>Thus, the answer is 14.1</span></span></span>
