Can you always draw a piecewise function without picking up your pencil.
Answer:
Yes
Step-by-step explanation:
A function is continuous on an interval if the graph has no breaks, jumps, or holes. You can draw it without picking up your pencil.

Suppose you have a line segment with endpoint (-1,2) and midpoint (3,4). Which of the following is the other endpoint of your segment?
Step-by-step explanation:
we know that midpoint of a segment is found from formula
x=(x1+x2)/2
and y=(y1+y2)/2
in this case x=3 and y=4 x2=-1 and y2=2
so x1=2x-x2 =2*3-(-1)=6+1=7
y1=2y-y2=2*4-2=8-2=6
the other endpoint is (7,6)

What is the slope of a line parallel to the given line?
Question Blank

What is the slope of a line perpendicular to the given line?
Question Blank
type your answer...
Answer:
Step-by-step explanation:
I'm still not exactly sure what the question really is, but the level suggests that it is
y = (6/7)x + 5
Any line that is parallel to this line has a slope of 6/7
Any line that is perpendicular to this line is a little more complicated.
slope of given line * slope of perpendicular line = - 1
6/7 * perpendicular slope = - 1
Multiply by 7
6*perpendicular slope = - 7
Divide by 6
perpendicular slope = - 7/6

An item is regularly priced at $15. Raina bought it at a discount of 65% off the regular price. How much did she pay
Answer:
She paid $5.25
Step-by-step explanation:
You would multiply 15 times 0.65 and then subtract that from 15 or you could multiply 15 times 0.35 because 100-65 is 35.

Dan had $10. He bought x pencils, each costing y cents .How much money did Dan have left?
Answer: Unknown...Well, just simplify.
Step-by-step explanation:
Since it says x and y, that is NOT a number. So the real question is, how can we solve the problem without numbers? Well that's pretty simple and easy. Since we don't know the number, we will just have to simplify. With no actual number, simplifying is basically the answer. Unless, you can find out the answer.
Dan has the amount of money left would be 10 - xy which is the form of an expression.
What is the algebraic expression?Algebraic expressions are mathematical statements with a minimum of two terms containing variables or numbers.
We have to determine the amount of money Dan has left.
We must only generalize since we don't know the exact quantity. Having no method of solving,
Dan had $10. He bought x pencils, each costing y cents which are given in the question.
quantity of pencils = x and cost of pencil = y
As per the given condition, the required solution would be:
⇒ remaining amount = 10 - quantity of pencils × cost of pencil
⇒ remaining amount = 10 - (x) × (y)
⇒ remaining amount = 10 - xy
Therefore, Dan has the amount of money left would be 10 - xy which is the form of an expression.

3_1/2 divided by 5/8
What is the answer
Answer:
28/5 or 5 3/5
Step-by-step explanation:
First you need to make the mixed number into an improper fraction, like this:
3 1/2 turns into 7/2
Next you will need to do the reciprocal of division and inverse operation:
7/2 times 8/5
Then solve it:
7/2 * 8/5 = 56/10
Last simplify:
28/5
or
5 3/5

Write the equation in slope-intercept form of the line given that the slope of the line is 5 and the line passes
through the point (3, 4)
Answer:
let's go...
Step-by-step explanation:
We should use this function to find the standard form the line :
[tex]y - y(given \: point) = (gradient) \times ( \: x - x(g \: p) \: ) \\ y - 4 = 5 \times (x - 3) \\ y - 4 = 5x - 15[/tex]
subtract the sides of the equation plus 4
[tex]y = 5x - 15 + 4 \\ y = 5x - 11[/tex]
And we're done buddy.
good luck ♥️♥️♥️♥️♥️.

) What is the distance between this pair of points?
(-5, 2) and (-5, 6)
Answer:
[tex]d=4[/tex]
Step-by-step explanation:
Distance Formula: [tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Simply plug in the 2 coordinates into the distance formula to find distance d:
[tex]d=\sqrt{(-5-(-5))^2+(6-2)^2}[/tex]
[tex]d=\sqrt{(-5+5)^2+(4)^2}[/tex]
[tex]d=\sqrt{(0)^2+16}[/tex]
[tex]d=\sqrt{0+16}[/tex]
[tex]d=\sqrt{16}[/tex]
[tex]d=4[/tex]

Stock Market At the beginning of the day the stock market goes down 50 3/4 points and stays at this level for most of the day. At the end of the day the stock market goes up 120 1/2 points from the at the beginning of the day. What is the total change in the stock market from the beginning of the day to the end of the day?
Answer:
69 3/4
Step-by-step explanation:
The stock market goes down to 50 3/4 at the beginning of the day
At the end of the day it goes up to 120 1/2
Therefore total change in the stock market from the beginning to the end of the day can be calculated as follows
= 120 1/2 - 50 3/4
= 241/2 - 203/4
= 279/4
= 69 3/4
Hence the total change in the stock market from the beginning to the end of the day is
69 3/4

what is the total cost of $16 if you include 5% GST and 20% tip
Answer:$20
Step-by-step explanation:
16 divided by 10 = 1.6 (10%)
1.6 times 2 = 3.2 (20%)
16 + 3.2 = 19.2
1.6 divided by 2 = 0.8 (5%)
19.2 + 0.8 = 20$

A line contains the points -1 , -4 and -6,11 what is the slope of a line that is parallel to this line
Answer: 3 I think !
Step-by-step explanation:
This is my question
[tex]f(x) = (x - 4)(x - 3) \\ g(x) = \frac{7}{(x - 4)(x + 4)} \\ f.g = (x - 4)(x - 3) \times \frac{7}{(x - 4)(x + 4)} \\ (x-4)s \: are \: simplified \\ f.g = \frac{(x - 3) \times 7}{x + 4} = \frac{7x - 21}{x + 4} \\ (f.g) (x) = \frac{7x - 21}{x + 4} [/tex]

What is the equation of the line that is perpendicular to y equals negative four x plus five and passes through the point four comma negative three ?
Answer:
y= 1/4x - 4
Step-by-step explanation:
use point slope form which is:
y - y1 = m(x - x1)
we know that the slope will be 1/4 because perpendicular is a negative reciprocal.
plug everything into point slope form:
y + 3 = 1/4 ( x - 4)
we distribute the 1/4 and then subtract the three and we get our answer
y= 1/4x - 4
