Try this method:
When a graph shifts right, replace 'x' with 'x' minus the number.
When it shifts down, subtract the number from 'y'.
So the final equation becomes: y = 4(x - 5)² - 18.
The answer is A.
The area of square TUVW is calculated as 3 times 3, giving 9 square units.
In terms of head lettuces, since 1 square unit accommodates 4 lettuces, 9 square units can house 9 times 4, totaling 36 lettuces.
For plot QRST, the area is determined by multiplying its length by its width: 12 times 6 equals 72 square units.
With 36 vegetables available for every 9 square units, we can partition 72 by 9 to yield 8 plots of 9 square units.
In total, this accounts for 8 times 36, resulting in 288 vegetables.
We can cultivate 8 types of vegetables, with each type yielding 36 vegetables.
To formulate a system of equations for Naomi and Hudson, who work at a dry cleaners where Naomi can iron 35 shirts per hour and Hudson can manage 20 shirts per hour, we know that together they worked 13 hours and completed a total of 395 shirts. Naomi, during her 13 hours, could potentially iron 455 shirts (13 x 35), meaning each hour Hudson worked lessens that number by 15 shirts. The difference of 60 shirts (455 - 395) indicates that Hudson worked for 3 hours and Naomi, therefore, for 10 hours. The resulting equation reflects this relationship: 35Y + 20X = 395.
Imagine having a pile of pennies and you want to determine if the count is odd or even without tallying them one by one. You can separate them into pairs by placing one coin in the left pile and one in the right.
If no coin is left unmatched, then the total number is even; if there is one coin remaining unpaired, the number is odd.
Let:
Lala represented as l
Polina represented as P
Goffy represented as G
The ratio for them is 6:5:3
Given that Polina's loudness measures 420 decibels, the total loudness can be computed as follows:
Total ratio=6+5+3=14
Thus, total loudness will be:
14/5×420
=1,176 decibels
