Step-by-step explanation:
Write the equation of the circle with center (-4, 8) and passes through the point (-2, -1)
Answer:
[tex](x+4)^2+(y-8)^2=85[/tex]
Step-by-step explanation:
The standard equation for a circle is given by:
[tex](x-h)^2+(y-k)^2=r^2[/tex]
Where (h, k) is the center and r is the radius.
We know that the center is (-4, 8). So, substitute -4 for h and 8 for k:
[tex](x-(-4))^2+(y-8)^2=r^2\\[/tex]
Simplify:
[tex](x+4)^2+(y-8)^2=r^2[/tex]
Now, we will need to find r.
We know that it passes through the point (-2, -1). So, we can substitute -2 for x and -1 for y and solve for r. So:
[tex](-2+4)^2+(-1-8)^2=r^2[/tex]
Evaluate:
[tex](2)^2+(-9)^2=r^2[/tex]
Square:
[tex]4+81=r^2[/tex]
Add:
[tex]r^2=85[/tex]
So, r squared is 85.
We don’t actually have to solve for r itself, since we will have to square it anyways.
So, we have:
[tex](x+4)^2+(y-8)^2=r^2[/tex]
Substituting 85 for r squared, we get:
[tex](x+4)^2+(y-8)^2=85[/tex]
And we have our equation.
Find the value of y (2y+5) (5x - 17) (3x-11)
Answer:
Hope it help, please give me BRAINLEST!
Step-by-step explanation:
2y + 5= |3y| + 3 = 3
x - 3= 2
[tex]\sqrt{x} + 2 = 2[/tex]
5x - 17= -3x = 2
3^(x )= 4
3 cos^(2)(x) + 2 cos(x)- 1 = 0
3x-11= [tex]\sqrt{x}[/tex] +3 = 8
2 = |3x|
x - 5= -3
What rule would you allow to test weather (x,y) is on line l
Answer:
Step-by-step explanation:
If a point (x, y) lies on a straight line, coordinates of the point will satisfy the equation.
Slope of a line passing through two points C(4, 5) and D(8, 10),
m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
m = [tex]\frac{10-5}{8-4}[/tex]
m = [tex]\frac{5}{4}[/tex]
Equation of the line passing through C(4, 5) and slope m = [tex]\frac{5}{4}[/tex]
y - y' = m(x - x')
y - 5 = [tex]\frac{5}{4}(x-4)[/tex]
y = [tex]\frac{5}{4}x-5+5[/tex]
y = [tex]\frac{5}{4}x[/tex]
If point B(4, 0) lies on the line CD,
0 = [tex]\frac{5}{4}(4)[/tex]
0 = 5
Which is not true.
Therefore, point B doesn't lie on line CD.

Traveling along a path from A to B, what is the ratio of the change in y to the change in x?
A. 5/3
B. 4/7
C. 3/5
D. 2/3
Answer:
Option C. is correct
Step-by-step explanation:
Slope of a Line
Suppose we know the line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the equation:
[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Please note the slope measures the ratio of the change in y to the change in x.
The points of the graph are A=(-3,-2) B=(7,4). Calculating the slope:
[tex]\displaystyle m=\frac{4-(-2)}{7-(-3)}[/tex]
[tex]\displaystyle m=\frac{6}{10}[/tex]
Simplifying by 2:
[tex]\displaystyle m=\frac{3}{5}[/tex]
Option C. is correct
What value of x satisfies the equation below? Explain
how you know
- 6x=
36
Answer:
-6 because -6 times -6 is a positive 36 negative times negative is positive
Step-by-step explanation:
Answer:
x = -6
Step-by-step explanation:
Okay so basically. The "-6" and the fact that the answer is a positive number shows that X must be a negative number. So let us set "-6" as a positive number. Divide 36 by 6 and the answer is = 6. Add a negative sign and X is -6.
passes through the points (−4, 2) and (12, 6)?
I'll assume you need to find the equation of the line that passes through those points.
Answer:
[tex]\displaystyle y-2=\frac{1}{4}(x+4)[/tex]
Step-by-step explanation:
Equation of a Line:
The equation of a line passing through points (x1,y1) and (x2,y2) can be found as follows:
[tex]\displaystyle y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]
The given points are (-4,2) and (12,6), thus:
[tex]\displaystyle y-2=\frac{6-2}{12+4}(x+4)[/tex]
Operating:
[tex]\displaystyle y-2=\frac{4}{16}(x+4)[/tex]
Simplifying, the equation in point-slope form is:
[tex]\mathbf{\displaystyle y-2=\frac{1}{4}(x+4)}[/tex]

Find the area of the triangle.
Choose the linear equation written in slope-intercept
form that matches each graph.
Answer:A
Step-by-step explanation:
The line touches the y axis at -1. The line then goes up 1 over 2 but since it’s on the bottom part of the graph it has the be negative. Y=-1/2X-1
Answer:
Slope = rise/run
= -1/2 (negative because the slope is decreasing)
y - intercept = -1
Option A
y = -1/2x-1
The following formula is for the area, A, of the curved surface area of a cone. A = pie x r x l, where r is the radius and l is the slant height of the cone.
Calculate the total surface area of a cone with radius 6cm and slant height 13cm
The volume V of gas varies inversely to the pressure P. The volume of a gas is 200 cm3 under pressure of 32 kg/cm2. What will be its volume under pressure of 40 kg/cm2?
Answer:
V = 160 cm³ when P = 40 kg/cm²
Step-by-step explanation:
V = k / P
Where,
V = volume
P = pressure
k = constant of proportionality
The volume of a gas is 200 cm3 under pressure of 32 kg/cm2
V = k / P
200 = k / 32
Cross product
200 × 32 = k
6,400 = k
k = 6,400
What will be its volume under pressure of 40 kg/cm2?
V = k / P
= 6,400 / 40
= 160
V = 160 cm³
If the US released 5.877 billion metric tons of carbon dioxide and 1 trillion pounds=0.4536 billion metric tons, how many trillions of pounds of carbon dioxide did the US release?
Answer: 12.96 trillion pounds
Step-by-step explanation:
From the question, we are informed that:
1 trillion pounds = 0.4536 billion metric tons
Therefore, if the US released 5.877 billion metric tons of carbon dioxide, the trillions of pounds of carbon dioxide that the US release will be:
= 5.877 / 0.4536
= 12.96 trillion pounds

9514 1404 393
Answer:
Same slope of 2Both are linearBoth are parallel to each otherStep-by-step explanation:
The y-intercepts are 0 and -7, so the vertical intercepts are not the same.
The one that is 0 represents a proportional relation; the one that is -7 represents a non-proportional relation. So, one is proportional and the other is not.
The x-coefficient is 2 in both cases, so the equations have the same slope of 2. Since the slopes are the same and the y-intercepts are different, the lines are parallel to each other.
Each is the equation of a line, so both functions are linear.

The sum of three consecutive numbers is 84. What is the largest of these numbers?
26
27
28
29
Answer:
29
Step-by-step explanation:
27 + 28 + 29 = 84
Answer:
D
Step-by-step explanation:
Let the first number be n.
Then the consecutive number will be (n+1).
And the second consecutive number will be (n+2).
We know that it totals 84. So, we can write the following equation:
[tex]n+(n+1)+(n+2)=84[/tex]
Let’s now solve for n. Combine like terms:
[tex]3n+3=84[/tex]
Subtract 3 from both sides:
[tex]3n=81[/tex]
Divide both sides by 3:
[tex]n=27[/tex]
So, our n or first term is 27.
This means that our sequence is: 27, 28, and 29.
So, our largest number is 29.
Hence, our answer is D.

What is the solution 8x-3(2x-4)=3(x-6)
Answer:
x = 30
General Formulas and Concepts:
Pre-Alg
Order of Operations: BPEMDASEquality PropertiesStep-by-step explanation:
Step 1: Define equation
8x - 3(2x - 4) = 3(x - 6)
Step 2: Solve for x
Distribute: 8x - 6x + 12 = 3x - 18Combine like terms: 2x + 12 = 3x - 18Subtract 2x on both sides: 12 = x - 18Add 18 to both sides: 30 = xRewrite: x = 30Step 3: Check
Plug in x to verify it's a solution.
Substitute: 8(30) - 3(2(30) - 4) = 3(30 - 6)Multiply: 240 - 3(60 - 4) = 3(30 - 6)Subtract: 240 - 3(56) = 3(24)Multiply: 240 - 168 = 72Subtract: 72 = 72The sum of two consecutive integers is two more than the third integer. Find the integers
Answer:
3, 4, 5Step-by-step explanation:
x - the first integer
x+1 - the next integer consecutive to x (the second consecutive integer)
x + x+1 - the sum of two consecutive integers
x+1+1=x+2 - the integer consecutive to x+1 (the third consecutive integer)
x+2 + 2 - two more than the third integer
x + x+1 = x+2 + 2
2x + 1 = x + 4
x + 1 = 4
x = 3
x+1 = 3+1 = 4
x+2 = 3+2 = 5
