Use the given information to write an equation of each parabola.
The parabola has focus (-8.0) and vertex at the origin
Step-by-step explanation:
use y^2=4px
p is the distance from the vertex to the focus, which is 8 units left
y^2=4(-8)x
y^2=-32x
Use y²=4px where p is the distance from the vertex to the focus,
p = 8 to the left,
so p = -8
Plug that in:
y² = 4(-8)x
Sole / simplify / multiply:
y² = -32x

Answer: [tex]y = \frac{1}{3}x-2[/tex]
This is the same as writing y = (1/3)x - 2
Slope = 1/3
y intercept = -2
======================================================
Explanation:
We first need to determine the slope
[tex]m = \frac{y_2-y_1}{x_2-x_1}\\\\m = \frac{-3-3}{-3-15}\\\\m = \frac{-6}{-18}\\\\m = \frac{1}{3}\\\\[/tex]
Then we'll use this value of m, along with (x,y) = (15,3), to determine the y intercept b value.
[tex]y = mx+b\\\\3 = (1/3)(15)+b\\\\3 = 5+b\\\\3 - 5 = b\\\\-2 = b\\\\b = -2[/tex]
You could use the other point (-3,-3) as well
[tex]y = mx+b\\\\-3 = (1/3)(-3)+b\\\\-3 = -1+b\\\\-3 +1 = b\\\\-2 = b\\\\b = -2[/tex]
Either way, we end up with the same y intercept. You don't need to show both sets of steps when computing b. You only need to pick one set of steps.
Since m = 1/3 and b = -2, we go from y = mx+b to y = (1/3)x - 2 which is the same as writing [tex]y = \frac{1}{3}x-2[/tex]
Answer:
y = 7/18 - 11/6
Step-by-step explanation:
y2 - y1 / x2 - x1
-3 - 4 / -3 - 15
-7/-18
= 7/18
y = 7/18x + b
4 = 7/18(15) + b
4 = 35/6 + b
-11/6 = b

Find the slope intercept form of an equation of the line perpendicular to the graph y = 2/3x - 5/3 and passing through the point (0, 6).
The perpendicular slope is:
State the y value of the y-intercept of the perpendicular line:
The equation of the perpendicular line is:
Answer:
Perpendicular slope: -3/2
Y-value of the y-intercept: 6
Linear equation of the perpendicular line: y = -3/2x + 6
Step-by-step explanation:
Perpendicular lines have negative reciprocal slopes, which means that multiplying the slopes of both lines will result in -1.
Given the linear equation, y = 2/3x - 5/3, and the point, (0, 6):
Let m1 = slope of line 1
m2 = slope of the other line
Since the slope of y = 2/3x - 5/3 is 2/3, then the other line must have a slope of -3/2 because:
m1 × m2 = -1
[tex](\frac{2}{3}) (-\frac{3}{2}) = -1[/tex]
Therefore, the slope of the other line (m2) = -3/2.
The y-intercept is the y-coordinate of the point where the graph of the linear equation crosses the y-axis. The y-intercept is also the value of y when x = 0. The given point has coordinates (0, 6), which means that it is the y-intercept. Its y-coordinate, (b) = 6.
Therefore, given the slope m = -3/2, and the y-value of the y-intercept, b = 6, then the equation of the perpendicular line is: y = -3/2x + 6.

Find the ordered pair (x,y) that satisfies the system of equations
x + y = 15
x - y = 3.
Answer:
(9, 6)
Step-by-step explanation:
add equations together: (x + y = 15) + (x - y = 3) --> x + x + y - y = 15 + 3 --> 2x = 18
isolate the variable: 2x/2 = 18/2 --> x = 9, so the x-coordinate is 9
substitute 9 in x's place in one of the equations: 9 + y = 15
solve for y: y = 15 - 9 --> y = 6, so the y-coordinate is 6
combine x and y coordinates together: (9, 6)
In a parking lot there are only white cars, green cars, and red cars. If one car is selected at random from the lot, the probability that the selected car would be a green car is one sixth and the probability that it would be a red car is one eighth. What is the probability that it would be a white car?
Answer:
17/24
Step-by-step explanation:
With the understanding that the three given cars form three mutually exhaustive and disjoint sets i.e., they form the partition of sample space, the probability that the selected car would be white is [tex]\frac{17}{24}[/tex].
What is partition of a sample space?A collection of sets B1, B2, . . . , Bn is said to partition the sample space if the sets (i) are mutually disjoint and (ii) have as union the entire sample space.
In this question, we take three sets - set of all red cars, white cars and green cars.
A car can be either red, white or green. Thus they are mutually exclusive.
Also, let the cars in parking lot be the sample space. Every car we pick has to be of one of the three colors. This imply that the three sets of the three cars are mutually exhaustive.
P(selecting a red car) + P (selecting a green car) + P(selecting a white car) = 1
[tex]\frac{1}{8} + \frac{1}{6} + P(selecting\ a\ white\ car) = 1\\\\ P(selecting\ a\ white\ car) = \frac{17}{24}[/tex]

plz help me in this question
Step-by-step explanation:
option A is correct
as, point S lies on = -7, 4
and point T lies on = 5, 4
so, diameter is 12 so radius = diameter/2 = 12/2 = 6
and center is - 1 , 4 as the diameter lies on 4 in y axis

5x-2 = -2+5x. a) infinite solution b) no solution c) 1 solution
[tex]▪▪▪▪▪▪▪▪▪▪▪▪▪ {\huge\mathfrak{Answer}}▪▪▪▪▪▪▪▪▪▪▪▪▪▪[/tex]
The given equation is :
[tex]5x - 2 = - 2 + 5x[/tex]here, 5x is on both sides, so they cancel out. hence value of x can't be determined.
so, the equation have no solution.
correct choice is B.) no solution
5x -2 = -2 + 5x
Add 2 to both sides to get 5x = 5x
Because this is true then any value of x will still make the equation true.
This means there are infinite solutions.
Answer: a) infinite solution
