Answer:
y - 8 = -1/4(x - 4)Step-by-step explanation:
Perpendicular lines have negative-reciprocal slopes.
The line contains point P(4, 8)
Point slope form:
y - y₁ = m(x - x₁)Given line:
y = 4x - 7The slope of the perpendicular line is m = -1/4.
The line in point-slope form is:
y - 8 = -1/4(x - 4)Answer:
y - 8 = -1/4(x - 4)
Step-by-step explanation:
If two lines are perpendicular to each other, they have opposite slopes.
The first line is y = 4x - 7. Its slope is 4. A line perpendicular to this one will have a slope of -1/4, the reciprocal (opposite) of the given equation.
Plug this value (-1/4) into your standard point-slope equation of y - y₁ = m(x - x₁)
y - y₁ = -1/4(x - x₁)
To find x₁ and y₁, we want to plug in a value that we know is on this line: in this case, it is P (4, 8). Plug in the x and y values into the x₁ and y₁ of the standard equation.
y - 8 = -1/4(x - 4)
This equation is perpendicular to your given equation (y = 4x - 7) and contains point P (4, 8)

Does stencil two overlap exactly with the original image? Describe what you see. After the transformations are complete, what can you say about the points that make up stencil one and the points that make up the original image ? Explain
Answer:
No, stencil two does not overlap the original pattern exactly. Not all the points on stencil two coincide with the points on the original pattern. There is a subtle difference near the boundaries of the two shapes.

Step-by-step explanation:
Given
[tex](\frac{1}{4})^3[/tex]
Required: Evaluate
The options are not clear. So, I'll answer without considering the options:
[tex](\frac{1}{4})^3[/tex]
Apply law of indices:
[tex](\frac{1}{4})^3 = (\frac{1}{4}) * (\frac{1}{4}) * (\frac{1}{4})[/tex]
Remove brackets
[tex](\frac{1}{4})^3 = \frac{1}{4} * \frac{1}{4} * \frac{1}{4}[/tex]
Combine
[tex](\frac{1}{4})^3 = \frac{1*1*1}{4*4*4}[/tex]

14 = 3y - 4
Help me pls
Answer:
y = 6
Step-by-step explanation:
I'm going to assume you want to solve for y.
Step 1: Move all constants to 1 side, isolating y and its coefficient:
14 = 3y - 4
14 + 4 = 3y - 4 + 4
18 = 3y
Step 2: Divide both sides by 3 to solve for y:
3y = 18
3y / 3 = 18 / 3
y = 6
Final answer: y = 6

-0.75, -7/10, -1/2, 0.50, 3/5
Answer:
-0.75, -7/10, -1/2, 0.50, 3/5
Step-by-step explanation:
put all of them as a decimal first
3/5 = 0.6 (5)
-1/2 = -0.50 (3)
0.50 = 0.50 (4)
-7/10 = -0.70 (2)
-0.75 = -0.75 (1)

Need this fast
Answer:
920 square feet
Step-by-step explanation:
Top: 20 * 17 = 340
Side triangles: 8 * 15 / 2 = 60
2 side triangles: 60 * 2 = 120
Back rectangle: 8 * 20 = 160
Bottom rectangle: 15 * 20 = 300
All of them: 340 + 120 + 160 + 300 = 920
The surface area is the sum of the area of the two similar triangles and the area of the three rectangles. Then the surface area of the geometry will be 920 square feet.
What is Geometry?It deals with the size of geometry, region, and density of the different forms both 2D and 3D.
The surface area of the geometry will be
The surface area is the sum of the area of the two similar triangles and the area of the three rectangles.
The area of the rectangles will be
Area of rectangles = 8 x 20 + 15 x 20 + 17 x 20
Area of rectangles = 160 + 300 + 340
Area of rectangles = 800 square feet
The area of the triangles will be
Area of triangles = 2 x 1/2 x 15 x 8
Area of triangles = 120 square feet
Then the area of the geometry will be
Area of geometry = 800 + 120
Area of geometry = 920 square feet

Given the line y =2/3x-3
Write the equation of a line perpendicular to it that passes
through the point (4, -1)
Answer:
y= -3/2x + 5
Step-by-step explanation:
You do the opposite reciprocal of the original equation's slope.
Then you use the new slope from the point (4,-1) on the graph to find the y-intercept. Which is (0,5).
That gets your answer of -3/2x + 5.

what value of x is quadrilateral CDEF a parallelogram
Answer:
x = 2
Step-by-step explanation:
CDEF is a parallelogram.
CE and FD are its diagonals.
Diagonals of a parallelogram bisects each other.
Therefore,
10x - 5 = 4x + 7
10x - 4x = 7 + 5
6x = 12
x = 12/6
x = 2
Thus, for x = 2, CDEF is a parallelogram.
In the quadrilateral CDEF, the value of x is 2.
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
Quadrilateral CDEF is a parallelogram.
Here, CE and FD are its diagonals.
We know that;
Diagonals of a parallelogram bisects each other.
Therefore, We can formulate;
⇒ 4x + 7 = 10x - 5
Solve for x as;
⇒ 7 + 5 = 10x - 4x
⇒ 12 = 6x
⇒ x = 12/6
⇒ x = 2

how to change
a fraction into a percent
Answer:
[see below]
Step-by-step explanation:
If you are given a fraction, convert it into a decimal by diving the numerator by the denominator.
After converting it into a decimal, you multiply it by 100 to get the percent value. After that, you add the percent sign.
Example:
[tex]\text{Convert \frac{5}{10} into a percent.}[/tex][tex]\text{Convert } \frac{5}{10} \text{ into a percent.}\\\\\\\rightarrow \text{Step One: Convert into decimal.}\\\\\frac{5}{10}=0.5\\\\\rightarrow \text{Step Two: Multiply by 100 and then add percent sign.}\\\\0.5 * 100 = 50\\\\[/tex]
50%
[tex]\frac{5}{10}=50[/tex]%
Hope this helps.
Answer:
Divide the numerator into the denominator, then move the decimal 2 places to the right.
Step-by-step explanation:
Let's use 3/4 as an example.
Divide 3 into 4 and you get 0.75
Move the decimal 2 places to the right and you get 75
Then just add a percent sign (75%)
