Write an equation in point-slope form for the line that passes through each point with the given slope (-1,-2) m= 3
Answer:
y + 2 = 3(x + 1)Step-by-step explanation:
The Point-Slope form of equation of a line with slope of "m" and passing through point (x₁, y₁) is: y - y₁ = m(x - x₁)
m = 3
x₁ = -1
y₁ = -2
Therefore the equation:
y - (-2) = 3(x - (-1))

arcsin0=? arccos0=? arctan1=?
Answer:
arcsin0= 0 degrees
arccos0= 90degrees
arctan1= 45 degrees
Step-by-step explanation:
To get arcsin0, let the unknown value be x
sin x = 0
Take arcsin of both sides
arcsin(sinx) = arcsin 0
x = arcsin0
x = 0 degrees
Hence arcsin0 = 0degrees
For cos x = 0
Take arccos of both sides
arccos(cosx) = arccos 0
x = arcscos0
x = 90 degrees
Hence arccos0 = 90degrees
For tan x = 1
Take arctan of both sides
arctan(tanx) = arctan 1
x = arctan1
x = 45 degrees
Hence arctan1 = 45degrees

Which of the following points solves the system shown below?
y = 5x -9
y = -2x + 12
Choose from the following...
1) (1, -4) 2) (2,8) 3) (3,6) 4) (-3, 18)
Answer:
(3,6)
Step-by-step explanation:
Collect like terms
y -5x = -9
y + 2x = 12
Using elimination method
Subtract equation 2 from equation 1
y - 5x = -9
y + 2x = 12
---------------
0. -7x = -21
Divide both sides by -7
-7x = -21
---- -----
-7 -7
x = 3
Substitute x=3 into equation 1
y = 5(3) - 9
y = 15 - 9
y = 6
Solution is (x,y) = (3,6)
Write an equation of the line that passes through the given point and is parallel to the given line.
(4, 3); y = –x + 5
Remember that the standard form of a line equation is y = mx + b. Since you need a line that is parallel to y = 5x - 2, the first thing to do is use the same slope (m), which is 5 in this case.
The new line would look like this: y = 5x + b. I use "b" instead of -2, since we'll calculate a "b" for the new line by substituting the given point of (2, -1) into y = 5x + b.
-1 = 5*(2) + b
b = -11
The parallel line that goes through (2,-1) is y = 5x - 11
The new line is the blue, on the right. Note that it is parallel to the original (green) line and also intersects at (2, -1). (Each chart is is 0.5 unit).
Answer:

Consider all positive integers that are multiples of 10 and are less than or equal to 200. What fraction of those integers are multiples of 15?
A. 1/20
B. 3/20
C. 3/10
D. 2/5
E. 3/4
The fraction of those integers are multiples of 15 will be 3/10. Then the correct option is C.
What is Algebra?The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
Consider all positive integers that are multiples of 10 and are less than or equal to 200.
Let the number of the positive integer that are multiples of 10 be x. Then the equation will be
10x ≤ 200
Then the value of the x will be
x ≤ 20
The set of numbers is given below.
Set = 20 {10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 110, 120, 130, 140, 150, 160, 170, 180, 190, 200}
The set which is divisible by 15 will be
Set = 6 {30, 6,0 90, 120, 150, 180}
Then the fraction of those integers are multiples of 15 will be
⇒ 6 / 20
⇒ 3/10
The fraction of those integers are multiples of 15 will be 3/10. Then the correct option is C.

Rectangle ABCD is graphed in the coordinate plane. The following are the vertices of the rectangle: A(-2, 1),B(3,1), C (3,4) D(-2,4). What is the perimeter of rectangle ABCD?
Answer:
16 units
Step-by-step explanation:
Rectangle perimeter = width + width + height + height = 2 (width) + 2 (height)
To find the length of one of the sides of the rectangle, I am going to find the distance between points A and B.
The y-xoordinates are the same for A and B, so this is a horizontal line. This means we are measuring the width of the rectangle.
To find the distance, we take 3 - -2 = 5 units
So the width of the rectangle is 5 units.
We can do the same thing to find the height of the rectangle using B and C.
They have the same x-coordinates, so the distance between them will be the difference in the y-coordinates.
4 - 1 = 3, so the height of the rectangle is 3.
Finally, to find the perimeter, we do 2(5) + 2(3) = 16 units
The perimeter of the rectangle is 16 units.
I hope this helps!

Write an expression that is the product of two factors and is equivalent to - 2x - 16.
Which expression is the product of two factors and is equivalent to - 2x - 16?
O A. -2x-1-15
OB. -2(x-8)
OC. (8x - 1)-(10x-15)
OD -2(X + 8)
Answer:
D
Step-by-step explanation:
Our answer will be D. We can eliminate choices A and C since they are not products. In other words, they are not multiplying factors together; they are only adding or subtracting.
Answer B does not work, as when it is multiplied out, we get -2x + 16.
When we find the product of D, we distribute the negative and get the correct product, -2x - 16
