Answer:
D
Step-by-step explanation:
money given by parents = $300
earning per hour = $8.5
0.2 × 8.5 = $1.7
y = saving for college
x = hours he worked
y = saving from wages + given by parents
y = 1.7x + 300
Answer:
Point (1,8)
Step-by-step explanation:
We will use segment formula to find the coordinates of point that will partition our line segment PQ in a ratio 3:1.
When a point divides any segment internally in the ratio m:n, the formula is:
Let us substitute coordinates of point P and Q as:
,
Therefore, point (1,8) will partition the directed line segment PQ in a ratio 3:1.

Step-by-step explanation:</h2>
If the graph of any function is an unbroken curve, then the function is continuous. Let's study the function at the the point [/tex]x=5[/tex]:
At this point the function has the following value:
, so the function in fact exists here, but let's find the limit here using:
So:
By factoring out this function we have:
Since then the function is continuous here.
Let's come back to our function:
If we factor out this function we get:
Notice that at x = 9 the denominator becomes 0 implying that at this x-value there is a vertical asymptote. The graph of this function is shown below and you can see that at x = 9 the function is not continous
Therefore, the answer is:
b. continous at every point exept
