Write the equation of the line that is parallel to the line y=3/2 x +5 and goes through the point (0,7)

1 answer:

3 0

First, you know that the slope will be the same (3/2).
Plug in the points 0 for x and 7 for y in order to find b.
7=3/2*0+b
b=7
Then put the new slope and y-intercept into the equation:
y=3/2x+7

The weight distribution of parcels sent in a certain manner is normal with mean value 17 lb and standard deviation 3.3 lb. The p

Yakvenalex [24]

Answer: The value of c would be 26.514 lb.

Step-by-step explanation:

Since we have given that

Mean = 17 lb

Standard deviation = 3.3 lb

At 99% level of significance, z = 2.58

So, it becomes,

$Z=\dfrac{X-\mu}{\sigma}\\\\2.58=\dfrac{X-17}{3.3}\\\\2.58\times 3.3=X-17\\\\8.514+17=X\\\\X=25.514$

So, the weight c would be

$c=25.514+1\\\\c=26.514$

Hence, the value of c would be 26.514 lb.

G(x) = –16x + x2 in vertex form.

Citrus2011 [14]

Answer:

$g(x)=(x-8)^2-64$

Step-by-step explanation:

The given function is;

$g(x)=-16x+x^2$

This is the same as;

$g(x)=x^2-16x$

Add and subtract the square of half the coefficient of x.

$g(x)=x^2-16x+(-8)^2-(-8)^2$

Observe that the first three terms is a perfect square trinomial.

$g(x)=(x-8)^2-64$

The vertex form is $g(x)=(x-8)^2-64$

The vertex (8,-64)
