point)
O y=-6x - 15
O y = -6x - 20
y=-6x + 15
Oy=-6x + 20
What’s the answer
Answers
Answer:
y= -6x - 15
Step-by-step explanation:
First you need to plug in the x and y coordinates into the equation y = -6x and you should get (-3) = -6(-2). Then you do -6 x -2 which is 12 then subtract 12 from -3 and get -15.

The relationship between the variables x, y and z is an illustration of similar triangles
The values of x, y and z are 6, [tex]\sqrt{117}[/tex] and [tex]\sqrt{52[/tex]
How to determine the values of x, y and zRight triangles are triangles with an angle measure of 90 degrees, and we have the following equivalent ratio from the triangle
[tex]x : 9 = 4 : x[/tex]
Express as fraction
[tex]\frac x9 = \frac 4x[/tex]
Cross multiply
[tex]x^2 = 36[/tex]
Take the square root of both sides
[tex]x = 6[/tex]
The value of y is then calculated using the following Pythagoras theorem
[tex]y = \sqrt{9^2 + x^2[/tex]
This gives
[tex]y = \sqrt{9^2 + 6^2[/tex]
[tex]y = \sqrt{117[/tex]
The value of z is then calculated using the following Pythagoras theorem
[tex]z = \sqrt{4^2 + x^2[/tex]
This gives
[tex]z = \sqrt{4^2 + 6^2[/tex]
[tex]z = \sqrt{52[/tex]
Hence, the values of x, y and z are 6, [tex]\sqrt{117}[/tex] and [tex]\sqrt{52[/tex]

P=250(0.88)x
C
P=12(250)x
D
P=−250(0.12)x
Answers
250 - 250 * 12% = 250 * (1 - 12%) = 250 * 0,88
with x = fish number
=> P = 250 * 0,88 * x
Answer: A. P=250(0.12)x

12%= 0.12
250 x 0.12 = the amount decreased by each week

Equation of circle: (x - h)² + (y - k)² = r²"h" represents the x coordinate of the center point, "k" represents the y coordinate of the center point, and "r" represents the radius of the circle.

In a class of 28 students, 15 earned an A on the final exam, 10 earned an A for the entire course, and 7 earned an A for both final exam and the entire course. What is the probability that a randomly selected student in this class did not earn an A on the final exam and did not earn an A for the entire course?
Answers
Using it's concept, it is found that there is a 0.3482 = 34.82% probability that a randomly selected student in this class did not earn an A on the final exam and did not earn an A for the entire course.
What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.
In this problem, we have that 13 out of 28 students did not earn an A on the final course, and 21 out of 28 students did not earn an A for the entire course, hence:
[tex]p = \frac{13}{28} \times \frac{21}{28} = 0.3482[/tex]

Tell whether (2, 5) is a solution of the equation y = 2x + 1. Show your work. I’LL PUT YOU AS BRAINLIEST
Answers
Answer:
The solution of (2,5) indeed equals the solution of the equation y=2x+1
Step-by-step explanation:
to solve just plug in the values.
y=2(2)+1 which gives us the y value of y=5
to solve for x, plug in y. 5=2x+1.
subtract 1 from both sides, and you get 4=2x
then divide 2 on both sides to get x, which is 2. therefore this is true.

Find the surface area of a square pyramid with side length 3 km and slant height 4 km.
Answers
Answer:
The pyramid consists of 4 triangles having bases of 3 km and height of 4 km (measured along the face)
A = 4 * 3 / 2 * 4 = 24 km^2
Each triangle has an area of 1/2 * bottom length * height
3 cannot refer to the length of one of the isosceles triangles because a slant height of 4 km is given and is less than one such side
The surface area of the square pyramid is 24 km².
What is the surface area of a square pyramid with a slant height?The surface area of a square pyramid with a slant height can be determined by the product of the base perimeter with the slant height divided by two.
Mathematically, it can be expressed as:
Surface Area S.A = P × l/2
where;
Side length (a) = 3Base perimeter (P) = 4a = 4(3) = 12kmSlant length (l) = 4 kmSurface Area (S.A) = 12 × (4/2)
Surface Area (S.A) = 24 km²

Answers
Step-by-step explanation:
just add all the given angles and equate it with 540° and then find x
x/2 + x/2 + x - 25 + 100 + x - 15 = 540°
3x + 60 = 540°
3x = 540 - 60
x = 480/3
x = 160°
on checking, the given shape values of x-25 and x - 15 are both still obtuse angles thus the answer is correct.
