Answer : The correct option is, (B) y=\frac{t-d}{31}

Step-by-step explanation :

As we are given that the expression as:

12y+d=-19y+t

By solving the term we get the value of 'y'.

12y+d=-19y+t

We are taking like terms together.

12y+19y=t-d

Now we are adding like terms, we get:

31y=t-d

y=\frac{t-d}{31}

Therefore, the equation correctly rewritten to solve for y is, y=\frac{t-d}{31}

The mean of a set of data is 90. Five of the six data points are given as 92, 201, 54, 43, and 13. What is the value of the sixt
STatiana [176]
The first step is to multiply 90 x 6 = 540, this is because the data should have 6 terms and since the mean is 90 all terms should add to 540, then add the terms you already have 92 +201+54+43+13= 403 but you need to have 540 so the last number is the difference 540 - 403 = 137

Write the equation of the parabola with a focus at (-3, -5) and a directrix at y = -7.
lilavasa [31]

Answer:

The directrix is negative so the equation will be

x^2=4ay

x=-3

y=-5

a=x^2/4y

a=(-3)^2 /4*(-5)

a=9/20

x^2=4*(9/20)*y

x^2=9/5y

Step-by-step explanation:

The directrix always determine the equation to use. It is also important to notice the sign(-+).

In the diagram below, every pair of segments which do not intersect are parallel, and the measure of angle k is 89 degrees. What
solong [7]
From the figure shown:
Given that k=89, then:
c=g=k=o=s=w=89
b=f=j=n=r=v=89
d=h=l=p=t=x=180-89=91
a=e=i=m=q=u=91
thus the sum of <span> s,e,q,u,o,i,a will be:
</span>s+e+q+u+o+i+a
=89+91+91+91+89+91+91
=633°

Answer: 633°
