Is the graph a linear function, non linear function, or relation

serious [3.7K]

a LINEar function has well, the graph of a straight line, so this isn't that.

is it a relation? well, yes, because the y-value correlates with the x-value, so one depends or relates to the other.

is it a non-linear function? well, a function has to pass the <u>vertical line test</u>, meaning if we draw vertical lines they must touch the graph only once on their way down.... and in this case it seems they do, so it is non-linear clearly, and it's also a function.

Destiny and Guadalupe are shopping. Destiny buys 2 pairs of pants and 6 bracelets and pays $178.Guadalupe buys 3 pairs of pants

ziro4ka [17]

For the entirety of this problem, p will represent a pair of pants and b will represent a bracelet.

Step 1) Set up equations for Destiny and Guadalupe

Destiny: 178 = 2p + 6b

Guadalupe: 155 = 3p + 2b

I will be using substitution to solve this problem, but elimination can also be used.

Step 2) Solve Destiny's equation for p

178 = 2p + 6b

178 - 6b = 2p

89 - 3b = p

Step 3) Substitute the found value of p from Destiny's equation into Guadalupe's equation and solve for b

155 = 3(89 - 3b) + 2b

155 = 267 - 9b + 2b

155 = 267 - 7b

-7b = -112

b = 16

Step 4) Use the value of b found in step 3, plug that back into our equation from step 2 and solve for p

89 - 3(16) = p

89 - 48 = p

p = 41

one pair of pants = $16

one bracelet = $41

Hope this helps!! :)

A square lawn has a length of 8 feet and a width of 8 feet. Eight researchers each examine a randomly chosen

Goshia [24]

The best approximation to the number of seedlings that are at least 2 inches high in the <u>entire lawn</u> is:

D. <u>6,400</u>

<h3><em>Total</em><em> Seedlings Calculation</em><em>.</em></h3>

To identify the total number of seedling in the entire lawn, first you must add all the seedling counted by the researchers:

Counted seedlings = 82 + 87 + 95 + 99 + 102 + 106 + 111 + 115
<u>Counted seedlings = 697</u>

Now, you must divide 697 in the number of regions taken by the researchers ( in this case were 8), this to obtain the average:

Average seedlings by region = $\frac{697}{8}$
<u>Average seedlings by region = 87.125</u>

Now, how we know, the entire lawn has a length of 8 feet and a width of 8 feet, it means 64 regions of one feet by one feet, by this reason, we multiply the average of seedlings by the whole regions in the lawn:

Number of seedlings in the lawn = 87.125 * 64
<u>Number of seedlings in the lawn = 5576</u>

Taking into account the average of seedlings is 5576, the best approximates of seedlings that are at least 2 inches high in the entire lawn is <u>6400</u>.
