What are the coordinates of the image of the point (1-, 2) under a dilation of 3 with the origin
Answer:
The image of the point (1, -2) under a dilation of 3 is (3, -6).
Step-by-step explanation:
Correct statement is:
What are the coordinates of the image of the point (1, -2) under a dilation of 3 with the origin.
From Linear Algebra we get that dilation of a point with respect to another point is represented by:
[tex]\vec P' = \vec R + r\cdot (\vec P-\vec R)[/tex] (Eq. 1)
Where:
[tex]\vec R[/tex] - Reference point with respect to origin, dimensionless.
[tex]\vec P[/tex] - Original point with respect to origin, dimensionless.
[tex]r[/tex] - Dilation factor, dimensionless.
If we know that [tex]\vec R = (0,0)[/tex], [tex]\vec P = (1, -2)[/tex] and [tex]r = 3[/tex], then the coordinates of the image of the original point is:
[tex]\vec P' = (0,0) +3\cdot [(1,-2)-(0,0)][/tex]
[tex]\vec P' = (0,0) + 3\cdot (1,-2)[/tex]
[tex]\vec P' = (3,-6)[/tex]
The image of the point (1, -2) under a dilation of 3 is (3, -6).

The table below shows the relationship between the number of cars sold and the amount of money earned by the car salesperson. Is the amount of money earned, in dollars, proportional to the number of cars sold?
Answer:
No, it is not proportional.
Step-by-step explanation:
This can be determined by looking at the first two items in the chart. I have looked at them all to find a certain pattern, but there wasn't any. The salesman earns $250 for one car sale, and he also earns $600 for two car sales, while this seems like it's just adding a $100 bonus, if you look at the third item on the chart adds a $200 bonus. You could be thinking that this is just adding a $100 bonus for how many cars were sold before, but then you move onto the fourth item on the chart. Which would give you $1,300 if the pattern was continued, yet instead the amount listed is $1,076.

[tex] {3x}^{2} - x + 4 = 0[/tex]
Answer:
[tex] x = \dfrac{1}{6} + \dfrac{i\sqrt{47}}{6} [/tex] or [tex] x = \dfrac{1}{6} - \dfrac{i\sqrt{47}}{6} [/tex]
Step-by-step explanation:
Use the quadratic formula.
[tex] x = \dfrac{-b \pm \sqrt{b^2 - 4ac}}{2a} [/tex]
[tex] x = \dfrac{-(-1) \pm \sqrt{(-1)^2 - 4(3)(4)}}{2(3)} [/tex]
[tex] x = \dfrac{1 \pm \sqrt{1 - 48}}{6} [/tex]
[tex] x = \dfrac{1 \pm \sqrt{-47}}{6} [/tex]
[tex] x = \dfrac{1}{6} \pm \dfrac{i\sqrt{47}}{6} [/tex]
[tex] x = \dfrac{1}{6} + \dfrac{i\sqrt{47}}{6} [/tex] or [tex] x = \dfrac{1}{6} - \dfrac{i\sqrt{47}}{6} [/tex]

Mark starts a rock climb when he is 1 mile above sea level. He can climb at the rate of 1.5 miles per hour. Which of the following functions would express Mark's height above sea level over time?
A. f( x) = 1.5 x
B. f( x) = 2.5 x
C. f( x) = 1 + 1.5 x
Answer:
C.
Step-by-step explanation:
Its C because you start out at 1 mile above sea level, then each time Mark climbs he goes up 1.5 miles per hour. f(x)= 1(starting point) + 1.15x (miles per hour).
PLS ANSWER FAST PLS Last year, 320 students were members of Pine Hill Middle School clubs. This year, there was a 20% increase in memberships. How many students are members this year?
Answer:
384
Step-by-step explanation:
First find 20% of 320
320 x .2 = 64
So this year, there is an increase of 64 students.
Add that to last year's 320
320 + 64 = 384
dai is comparing how many trading cards he has with his friend maura. initially they find that dai has four more cards than twice the number maura has
Answer:
B) [tex]2n+4[/tex]
Step-by-step explanation:
The question states that Dai has 4 more cards than twice the number of cards Maura has.
"more" - add
"twice" - multiply by 2
Let n be equal to the number of cards that Maura has.
Let D be equal to the number of cards that Dai has.
When we translate this into an equation, we would get something that looks like...
[tex]D=2n+4[/tex]
Since Dai has four more cards than twice the number of cards Maura has, 2 times the number of cards Maura has plus four is equal to the number of cards Dai has. Hopefully this is easier to understand written like an equation!
Therefore, the expression would be [tex]2n+4[/tex].
I hope this helps!

Mr green Drove 100 mies in 2 hours he continues to drive the same speed how long will mr green take to drive 400 more miles
Answer:
It would take him 8 hours
Since every 50 miles takes 1 hour
━━━━━━━☆☆━━━━━━━
▹ Answer
8 Hours
▹ Step-by-Step Explanation
First, find the unit rate:
100 miles ÷ 2 hours = 50 mph
Now, we need to find the time it takes to drive 400 miles so we will divide:
400 miles ÷ 50 mph = 8 hours
If you are looking for total hours, you would add:
2 hours + 8 hours = 10 hours
If you are looking for how long it'll take to drive the 400 miles, it would just remain 8.
Hope this helps!

In the diagram shown, l is a transversal. For what value of x will m and n be parallel? Give you answer to the nearest tenth.
Answer:
x = 22.4
Step-by-step explanation:
If (3x + 4) and (5x - 3) are supplementary as same side interior angles of the transversal l, then lines m and n are parallel.
Thus,
(3x + 4) + (5x - 3) = 180
Solve for x
3x + 4 + 5x - 3 = 180
Collect like terms
8x + 1 = 180
Subtract 1 from both sides
8x = 180 - 1
8x = 179
Divide both sides by 8
8x/8 = 179/8
x = 22.375
x = 22.4 (to nearest tenth)
Thus, for lines m and n to be parallel, the value of x will be 22.4.
The photo shows an overhead view of airport runways. Determine whether each pair of lines appear to be parallel or perpendicular
Parallel or perpendicular
Lines 2 and 3
Lines 1 and 3
Lines 1 and 2
Answer:
Lines 2 and 3
Step-by-step explanation:
Lines 2 and 3 are parallel lines.
Lines 1 and 3 are perpendicular lines.
The lines 1 and 2 are perpendicular lines.
What are parallel lines?Lines in a plane that are consistently spaced apart are known as parallel lines. Parallel lines don't cross each other.
Given:
The photo shows an overhead view of airport runways.
Those lines that are perpendicular to each other that means create an angle of 90° at intersecting point are perpendicular lines.
Lines in a plane that are consistently spaced apart are known as parallel lines. Parallel lines don't cross each other.
From the diagram,
Lines 2 and 3 are parallel lines.
Lines 1 and 3 are perpendicular lines.
The lines 1 and 2 are perpendicular lines.
Therefore, lines 2 and 3 are parallel lines and lines 1 and 3 and lines 1 and 2 are perpendicular lines.

Addison works at a pet store. She worked less than 40 hours last week.
Create an inequality that represents the number of hours, n, Addison worked last week.
Answer:
Step-by-step explanation:
Let the number of hours she worked last week be n. If Addison worked less than 40 hours last week, this is expressed as:
n < 40 here < represents the less than sign. This means that Addison cannot work for any hour that is 40 and greater, she can only work for hours less than 40 e.g 39, 38hr etc.
The correct inequality expression is n< 40
