Answer:
29 hours
Step-by-step explanation:
If he earned $404.70 per 19 hours, you do 404.70/19 to figure out the amount he earns per hour. 404.7/19 is 21.3. He earns $21.3 per hour. to solve, you find how many times 21.3 goes into 617.7 or 617.7/21.3. That is 29. He needs to work 29 hours to earn $617.70
Functions are used to represent tables and equations
- The function that represents the number of imports is f(x) = 2x
- The function that represents the number of exports is f(x) = 2 + x
<h3>How to determine the import function</h3>
From the table, we can see that the values of the import is twice the number of months
This is represented as:
y = 2x
Rewrite as a function
f(x) = 2x
Hence, the function that represents the number of imports is f(x) = 2x
<h3>How to determine the export function</h3>
From the table, we can see that the values of the export is two more than the number of months
This is represented as:
y = 2 + x
Rewrite as a function
f(x) = 2 + x
Hence, the function that represents the number of exports is f(x) = 2 + x

Answer:
2x - y = 0
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 2x - 1 ← is in slope- intercept form
with slope m = 2
Parallel lines have equal slopes, thus
y = 2x + c ← is the partial equation
To find c substitute (1, 2) into the partial equation
2 = 2 + c ⇒ c = 2 - 2 = 0
y = 2x ← equation in slope- intercept form
Subtract y from both sides
0 = 2x - y , that is
2x - y = 0 ← equation in standard form
Answer:
Step-by-step explanation:
Focus on #7. Let's combine the first two matrices inside round parentheses.
We get
-2 - 1
4 + 3
and so the original problems becomes
-3 4
3( [ ] + [ ] )
7 2
Combining the two matrices, we get the following:
1 3
3([ ]) = [ ]
9 9
