Passes through (-6, -1) and parallel to. x - y = 4
what is the equation of the line?
Answer:
y = x + 5
Step-by-step explanation:
1) First, find the slope of the line [tex]x-y = 4[/tex]. We can do this by setting it up in slope-intercept form, represented by the equation [tex]y = mx + b[/tex]. Whatever [tex]m[/tex] or the coefficient of the x-term is will be the slope. Isolate y in the equation:
[tex]x-y = 4\\-y = -x+4\\y = x -4[/tex]
So, the slope of the given equation is 1. Parallel lines share the same slope, thus the slope of the new line will be 1 as well.
2) Now, use the point-slope formula [tex]y-y_1 = m (x-x_1)[/tex] to write the equation of the line in point-slope form. Substitute values for [tex]m[/tex], [tex]x_1[/tex], and [tex]y_1[/tex] in the formula.
Since [tex]m[/tex] is the slope, substitute 1 for it. Since [tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of one point the line passes through, substitute the x and y values of (-6, -1) into those places as well. Then, isolate y in the resulting equation to put the equation in slope-intercept form and find the answer:
[tex]y-(-1) = 1 (x-(-6))\\y + 1 = 1 (x + 6)\\y + 1 = x + 6\\y = x + 5[/tex]

If a right triangle has two legs a=7 and b=4, what is the length of the hypotenuse
Finding perimeter and area.
Answer:
1. P = 14cm; A = 10cm^2
2. P = 24cm; A = 12cm^2
3. P = 32cm; A = 63cm^2
4. P = 36cm; A = 80cm^2
5. P = 32cm; A = 60cm^2
6. P = 36cm; A = 81cm^2
7. P = 26cm: A = 30cm^2
8. P = 28cm; A = 49cm^2
9. P = 26cm: A = 42cm^2
Step-by-step explanation:
Formula to find perimeter for a rectangle:
length + width + length + width
l + w + l + w
Formula to find area for a rectangle:
length × width
l × w
1.
Perimeter (P): 5 + 2 + 5 + 2 = 14
Area (A): 5 × 2 = 10
2.
P: 6 + 2 + 6 + 2 = 24
A: 6 × 2 = 12
3.
P: 7 + 9 + 7 + 9 = 32
A: 7 × 9 = 63
4.
P: 10 + 8 + 10 + 8 = 36
A: 10 × 8 = 80
5.
P: 10 + 6 + 10 + 6 = 32
A: 10 × 6 = 60
6.
P: 9 + 9 + 9 + 9 = 36
A: 9 × 9 = 81
7.
P: 10 + 3 + 10 + 3 = 26
A: 10 × 3 = 30
8.
P: 7 + 7 + 7 + 7 = 28
A: 7 × 7 = 49
9.
P: 6 + 7 + 6 + 7 = 26
A: 6 × 7 = 42
Area will always have its units squared (cm^2) because the formula requires we multiply the numbers and therefore the units: cm × cm = cm^2

A right triangle is inscribed in a circle. Determine the area of the shaded region. Use
3.14 for \piπ and round to the nearest tenth.
Answer:
Step-by-step explanation:
[tex]\text{The radius of the circle is }r=\sqrt{3^2+3^2}\\ \\ r=\sqrt{18}\\ \\ \text{The area is }A=3.14r^2\\ \\ A=3.14(18)\\ \\ A=56.52\\ \\ \text{The area of the triangle is }A=6(6)/2\\ \\ A=18\\ \\ \text{The shaded area is the area of the circle minus the area of the triangle.}\\ \\ A=56.52-18\\ \\ A=38.52ft^2\\ \\ A\approx 38.5ft^2\text{ (rounded to nearest tenth)}[/tex]

An airplane company wants to make a model of an 87 foot airplane. The scale they are using is 2in=8ft. How many inches long with the model airplane be?
Question 2 options:
16 inches
21.75 inches
2 inches
10.875 inces
Answer:
B. 21.75 inStep-by-step explanation:
The length of the airplane = 87 feet
The scale
2in = 8ft ⇒ 1 ft = 2/8 in ⇒ 1 ft = 1/4 inThe length of the model:
87*1/4 in = 21 3/4 in = 21.75 inCorrect choice is B

The blue figure is a dilation image of the black figure. The origin is the center of dilation. Tell whether the dilation is an enlargement or a reduction. Then find the scale factor of the dilation.
Answer: Reduction, 1/5
Because the image is smaller than the pre-image, it would be a reduction. Then you would count the length of one side of the Images. The length of the pre-image is 20 and the new image is 4. Then you would make a ratio of the new image to the pre-image which is 4/20, which simplifies to 1/5.
Hope this helps!
The scale factor of the dilation will be 1/4.
What is Division method?Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications. For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.
Given that;
The blue figure is a dilation image of the black figure.
And, The origin is the center of dilation.
Now,
Since, The blue figure is a dilation image of the black figure.
And, The origin is the center of dilation.
Here, The length of black figure = 16 units
And, The length of blue figure = 4 units
So, The scale factor of the dilation = 4/16
= 1/4
