C. f(x)=2/3x-2

<h2>Explanation:</h2>

Looking at the graph we realize that the y-intercept is given by:

b=-2

The Slope-intercept form of the equation of a line is given by:

y=mx+b

So, our equation becomes:

y=mx-2

So the only option that matches a negative y-intercept is C. Let's see that the slope m=2/3. Look at the y-intercept, if you increase x by 3 units, then y increases by 2 units and goes from x=-2 to x=0. In other words:

Change \ in \ x=\Delta x=3 \\ \\ Change \ in \ y=\Delta y=2 \\ \\ \\ m=\frac{\Delta y}{\Delta x}=\frac{2}{3}

For the Parabolay = (x – 7)2 – 3. the equation for the Line Of Symmetry is
devlian [24]

Answer:

x = 7

Step-by-step explanation:

y = (x – 7)^2 – 3

This equation is in vertex form

y = a(x-h)^2 +k

where (h,k) is the vertex

For a vertical parabola, the line of symmetry is x=h

x = 7

A sample of 20 joint specimens of a particular type gave a sample mean proportional limit stress of 8.41 mpa and a sample standa
nignag [31]

For this problem, the confidence interval is the one we are looking for. Since the confidence level is not given, we assume that it is 95%.

 

The formula for the confidence interval is: mean ± t (α/2)(n-1) * s √1 + 1/n


Where:

<span>
</span>

α= 5%


α/2 = 2.5%


t 0.025, 19 = 2.093 (check t table)


n = 20


df = n – 1 = 20 – 1 = 19

So plugging in our values:


8.41 ± 2.093 * 0.77 √ 1 + 1/20


= 8.41 ± 2.093 * 0.77 (1.0247)


= 8.41 ± 2.093 * 0.789019


= 8.41 ± 1.65141676

Answer: 48

first you do 2x3 then divided by 2 to get one of the small triangles which is 6/3= 2 then double that to get the other small triangle so you have 2+2=4
then you find the area of the rectangle which you do 8+3 to get the whole of the length so it’s then 11x4= 44
then add the 4 from the two triangles and you get the area as 48
i think this is right
