First solve for y

3x-y-2=1

subtract 3x from each side

-y-2=-3x+1

add 2 to both sides

-y=-3x+3

divide each side by -1

y=3x-3

To graph you could make a table:

x y

0 -3

graph that.... point and use rise over run for slope 3/1 and graph.

Mrs. Nguyen used 1.48 meters of netting to make 4 identical mini hockey goals. How much netting did she use per goal?

snow_tiger [21]

0.37 meters of netting

<h3>Further explanation</h3>

<u>Given:</u>

Mrs. Nguyen used 1.48 meters of netting to make 4 identical mini hockey goals.

<u>Question:</u>

How much netting did she use per goal?

<u>The Process:</u>

We will solve the problem of conversion or in other words the ratio or proportion.

Option A: the conversion

Mrs. Nguyen used 1.48 meters of netting to make 4 identical mini hockey goals.

Then for every 1 goal, she needs 0.37 meters of netting.

Because $\boxed{ \ 1 \ goal \times \frac{1.48 \ meters}{4 \ goals} = 0.37 \ meters \ of \ netting.}$

Option B: the ratio (or proportion)

In the ratio, we process as follows:

$\boxed{ \ 4 \ goals : 1.48 \ meters \ of \ netting \ }$

Both are divided by 4.

$\boxed{ \ 1 \ goals : 0.37 \ meters \ of \ netting \ }$

Thus, she uses 0.37 meters of netting per goal.

Alternative problem

How much netting did she use for 8 goals?

$\boxed{ \ 8 \ goal \times \frac{1.48 \ meters}{4 \ goals} = \ ? \ }$ meters of netting.

We cross out eight and four because they can be divided.

$\boxed{ \ 2 \times 1.48 \ meters = 2.96 \ meters \ of \ netting. \ }$

She uses 2.96 meters of netting to make 8 identical mini hockey goals.

Write the first trigonometric function in terms of the second for θ in the given quadrant.. sec θ, sin θ; θ in quadrant I

Grace [21]

We have sec = 1/cos

Then we also have cos^2 = 1 – sin^2

Also we have cos = sqrt (1 – sin^2)

Substitute the derived cosine function to sec then we have

Sec = 1/(sqrt(1-sin^2)

Find the first 3 iterates of the function f (x) = x - 4 when Xo = -11.

nikdorinn [45]

<h3>Answer: Choice A</h3>

-11, -15, -19

================================================

Explanation:

Plug x = -11 into the function.

f(x) = x-4

f(-11) = -11-4

f(-11) = -15

The output -15 is now the input to set up the next iteration.

f(x) = x-4

f(-15) = -15-4

f(-15) = -19

The first three iterates are -11, -15, -19
