Answer:
y - 5 = -4(x + 1)
Step-by-step explanation:
The point-slope form is y - k = m(x - h). The point is (h, k): (-1, 5) and the slope is -4.
Here we have y - 5 = -4(x + 1)
The required point-slope form of the equation of the line is y - 5 = -4(x + 1).
Given that, To determine an equation in point-slope form for the line that passes through the point with the given slope. point: (-1, 5) and m=-4.
The slope of the line is a tangent angle made by line with horizontal. i.e. m =tanx where x in degrees.
Here,
The point-slope of the equation of the line is given by,
y - y₁ = m(x - x₁)
Put the values in the above equation of the line
y - 5 = -4 (x - (-1))
y - 5 = -4 (x + 1)
Thus, the required point-slope form of the equation of the line is y - 5 = -4(x + 1).

If I have a circle that is 12 in in diameter and it's cold and a half and then folded in half again what is the area of the resulting shape and what is how do I write out the equation
Answer:
A= πr^2/4Step-by-step explanation:
Step one:
given data
diameter of circle= 12 in
the radius is r=d/2=6in
the area of the circle is
A=πr^2
A=3.142*6^2
A=3.142*36
A=113.1in^2
If the circle is folded in half, the area will be A/2= 113.1/2= 56.55in^2
In the corresponding shape is folded again the area is A/4= 28.3in^2
The expression for the last shape is
A= πr^2/4

Solve this algebraic expression:
5x-2(3x)
Answer:
-x
Step-by-step explanation:
Simplifying
5x + 2 = 3x
Reorder the terms:
2 + 5x = 3x
Solving
2 + 5x = 3x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-3x' to each side of the equation.
2 + 5x + -3x = 3x + -3x
Combine like terms: 5x + -3x = 2x
2 + 2x = 3x + -3x
Combine like terms: 3x + -3x = 0
2 + 2x = 0
Add '-2' to each side of the equation.
2 + -2 + 2x = 0 + -2
Combine like terms: 2 + -2 = 0
0 + 2x = 0 + -2
2x = 0 + -2
Combine like terms: 0 + -2 = -2
2x = -2
Divide each side by '2'.
x = -1
Simplifying
x = -1
= -x

Tell whether the expression in the pair is equivalent.
(the asterisks '*' stand for multiplication)
vwx * yz and v * w * zxy
Answer:
Yes
Step-by-step explanation:
Let's say each letter was a different number. When it comes to multiplication the order doesn't matter, plus the numbers that are together are just number multiplied.
Example:
(1)(2)(3)*(4)(10)Equals 240
If you switch those around, no matter what it will equal 240
Answer: They are equivalent
Both expressions have one copy of v, w, x, y, and z in some order all being multiplied. We can multiply any two numbers in any order we want
a*b = b*a
For example,
2*3 = 3*2
Since both equal 6.
We can extend this idea out to more than two things being multiplied and the order still doesn't matter. This idea is the commutative property of multiplication.

1. Which of the following is the equation of a line that has a slope 5 and passes through the point
(3,- 7)?
Answer:
Hope this helps!
Step-by-step explanation:
Answer:
Step-by-step explanation:
Given
point (3,-7)
m = 5
Solution
y - y1 = m(x - x1)
y - (-7) = 5(x - 3)
y + 7 = 5x - 15
y = 5x - 15-7
y = 5x-22
Answer
The equation in point-slope form that passes through the point (3,-7)and has a slope of 5 is line Y=5x-22
Determine if the equations are parallel, perpendicular, or neither
y = 3x + 5 and y = -1/3x +6
Answer:
Answer: Perpendicular.
Step-by-step explanation:
If you multiply the slopes together you will get -1:
[tex]3 * -\frac{1}{3} = -1[/tex]
Parallel means they have the same slope, so that is easily ruled out here.
If 2 (3t - 10) + t = 40 + 4t, what is the value of 3t?
The value of 3t is given by the equation A = 75
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
2 ( 3t - 10 ) = 40 + 4t
On simplifying the equation , we get
6t - 60 = 40 + 4t
Subtracting 4t on both sides of the equation , we get
4t - 60 = 40
Adding 60 on both sides of the equation , we get
4t = 100
Divide by 4 on both sides of the equation , we get
t = 25
So , the value of 3t = 25 x 4
The value of 3t = 75
Hence , the equation , 3t = 75
