Write the equation for the graph of y = | x | translated left 4 units

1 answer:

Lerok [7]3 years ago

Answer: y = |x+4|

Explanation:

Imagine that the graph of y = |x| is carved in stone so it cannot move. What we can move though is the xy axis. If we move the xy axis 4 units to the right, then this gives the illusion the V shaped curve is moving 4 units to the left. It goes opposite whatever movement you do to the xy axis.

If we replaced x with x+4, then this moves the xy axis 4 units to the right.

Therefore, going from y = |x| to y = |x+4| will have the V shaped curve moving 4 units to the left.

12 lunches cost $85

Explanation:
“Fancy lunch for $5 each” the key word: each, tells us that one lunch cost $5
Since he is buying 12 lunches you would need to multiple 5 by 12 to get 60 dollars.

The $25 is the amount of money to join the lunch club, so that mean you would need to add that to get the total money he spend.

Equation would be C=5(12)+25
12= lunches he bought

Answer:

Approximate maximum height is <em>5 ft</em>

$h(\frac{18}{32} )= 5 \ ft$

Step-by-step explanation:

$h(t)=-16t^{2} + 18t$ ---------- (1)

Differentiate equation (1) w.r.t <em>t </em>and equate it to zero (in order to determine maxima)

$h^{'}(t) = -32t+18$

$0= -32t+18$

$t=\frac{18}{32}$

Substitute this value in equation (1)

$h(\frac{18}{32} )=-16(\frac{18}{32} )^{2} + 18(\frac{18}{32} )$

$h(\frac{18}{32} )=-5+ 10$

$h(\frac{18}{32} )= 5 \ ft$

Brendan worked 7 11/12 hours on Saturday, on Sunday he worked 84% of the hours he worked on Saturday. How many total hours do he

Vesnalui [34]

Answer:

$14\frac{17}{30}$ hrs

Step-by-step explanation:

Given parameters:

Time worked on Saturday = $7\frac{11}{12}$

Unknown:

Total hours he worked last weekend = ?

Solution:

Since Brendan worked 84% of the time he worked on Saturday on Sunday;

Time worked on Sunday = $\frac{84}{100}$ x $\frac{95}{12}$ = $\frac{133}{20}$

Total time worked last weekend = Time worked on Saturday + Time worked on Sunday;

Total time worked = $\frac{95}{12}$ + $\frac{133}{20}$

Total time worked = $\frac{475 + 399}{60}$

Total time worked = $\frac{874}{60}$

Total time worked = $\frac{437}{30}$ = $14\frac{17}{30}$ hrs

olchik [2.2K]

Answer:

The amount of stock for which both brokers would charge the same commission is $2500.

Step-by-step explanation:

i) Let the amount of stock to be traded be worth $x

ii) therefore for both the brokers to charge the same commission we can write

1% of x = $25 $\RIghtarrow$ $\Rightarrow$ 0.01 $\times$ x = 25 $\therefore$ x = $\frac{25}{0.01} = 2500$

The amount of stock for which both brokers would charge the same commission is $2500.
