The city council is planning a long, narrow park with a playground at one end and a fountain at the other. They want the playgro

ipn [44]

Answer:

The following are some inequalities that represent the possible position of the playground.

2x ≥ -2 and x < -3

x + 3 ≤ 1 and –x > -3

x + 4 ≤ 2 and x + 4 > 7

2x – 1 ≥ -5 and 3x < 9

The city council planning for playground, that is more than 5 blocks from fountain and at least 2 blocks from center of park.

A solid dot on negative two points less than -2 and a circle dot on positive three points in the direction indicating greater than 3. So the right inequality is x + 3 ≤ 1 and –x > -3. That represents the possible position of ground.

Hence, the inequality x + 3 ≤ 1 and –x > -3 is the playground's possible position.

Two mechanics worked on a car. The first mechanic worked for

Dima020 [189]

X - the rate charged by the first mechanic
y - the rate charged by the second mechanic

The sum of the two rates was $155.
$x+y=155 \\
y=155-x$

The first mechanic worked for 10 hours, the second mechanic worked for 5 hours, and together they charged $1000.
$10x+5y=1000 \ \ |\div 5 \\
2x+y=200 \\
y=200-2x$

Set 155-x and 200-2x equal to each other:
$155-x=200-2x \\
-x+2x=200-155 \\
x=45 \\ \\
y=155-x=155-45=110$

The rate charged by the first mechanic was $45, and the rate charged by the second mechanic was $110.

Write the expressions for when you translate the graph of y = x+2 a) one unit up, b) one unit down, c) one unit to the left, d)

Aleksandr-060686 [28]

Answers and Step-by-step explanations:

Vertical transformations affect the entire function, while horizontal transformations influence only the x - only the x is altered. Vertical transformations include vertical stretches and shrinks, reflections over the x axis, and translations up and/or down. Horizontal transformations are horizontal stretches and shrinks, reflections over the y axis, and translations left and/or right.

a) "translate one unit up"; since we're translating <em>up</em>, we know this is a vertical translation, which will affect the entire function. So, the function will go from y = x + 2 to y = (x + 2) + 1 or y = x + 3.

b) "translate one unit down"; again, since we're translating <em>down</em>, we know this is another vertical translation, which will affect the entire function. So, our function goes from y = x + 2 to y = (x + 2) - 1 or y = x + 1.

c) "translate one unit to the left"; since we're translating to the <em>left</em>, we know that this will be a horizontal transformation, which will only affect the x. So our function goes from y = x + 2 to y = (x + 1) + 2 or y = x + 3. (Note that "left" will use a "+" sign because horizontal transformations are weird and "backward")

d) "translate one unit to the right"; again, since we're moving to the <em>right</em>, we know this is another horizontal transformation, which will only affect the x. So our function goes from y = x + 2 to y = (x - 1) + 2 or y = x + 1. (Again note that "right" uses "-" instead of "+" as we would think because horizontal transformations are weirdly "backward").

Hope this helps!
