Find the equation of the line determined by the given information.
10.m= 1; P = (-7, 0)
Answers
Answer:
y = x + 7
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b ) a point on the line
here m = 1 and (a, b ) = (- 7, 0 ) , then
y - 0 = 1 (x - (- 7) ) , that is
y = 1 (x + 7) ← distribute by 1
y = x + 7 ← in slope- intercept form

Answer:
Total surface area of the tent that is in a shape like a triangular prism
= 255ft²
Step-by-step explanation:
Find the surface area of the triangles.
height = 5ft, base = 5ft
2 Triangles = 5 × 5 ÷ 2 × 2 = 25ft²
Now for the base.
height = 10ft, base = 5ft
base of triangular prism = 10ft × 5ft = 50ft²
And then, the last 2 rectangles.
height = 10ft, base = 9ft
2 Rectangles = 10ft × 9ft × 2 = 180ft²
Lastly, we add all these up.
25ft² + 50ft² + 180ft²
= 255ft²
Sorry, I am just dum, What would be the area of this triangle? It is in demos and that last line underlined was just added to complete the triangle or else there would be no bottom line for the triangle.
Answers
Answer:
A = 5 units²
Step-by-step explanation:
the area (A) of a triangle is calculated as
A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )
here b = AC = 5 and h = AB = 2 , then
A = [tex]\frac{1}{2}[/tex] × 5 × 2 = 2.5 × 2 = 5 units²

Assuming x and the number below are measured in degrees find re value of x and find the unknown angle measure in each triangle.
Answers
Answer:
x = 16°
4x-7 = 57°
3x+4 = 52°
5x-9 = 71°
Step-by-step explanation:
All angles of any triangle add up to 180°, so if we add up each equation and set it equal to 180 we can find x.
4x-7 + 3x+4 + 5x-9 = 180
Simplify by combining like terms.
12x-12 = 180
Then, do inverse operations to find x.
12x=192
x=16
Now that we found x, we can substitute 16 for x in each angle equation in the triangle.
4(16)-7 = 57
3(16)+4 = 52
5(16)-9 = 71

The standard diameter of a golf ball is 42. 67 mm. A golf ball factory does quality control on the balls it manufactures. Golf balls are randomly measured to ensure the correct size. One day, an inspector decides to stop production if the discrepancy in diameter is more than 0. 002 mm. What is the range of acceptable values? 42. 668 mm to 42. 670 mm 42. 668 mm to 42. 672 mm 42. 670 mm to 42. 672 mm 42. 670 mm to 42. 674 mm.
Answers
The maximum and minimum acceptable diameter of the golf ball in the factory will be 42.672 mm to 42.668 mm.
What is the range?The range is the difference between the maximum and minimum.
Given to us
The standard diameter of a golf ball is 42.67 mm.
The discrepancy in diameter is more than 0.002 mm.
As it is given to us that the standard diameter of the golf ball is 42.67 mm while the discrepancy in diameter is more than 0.002 mm.
Maximum acceptable diameter = 42.67 mm + 0.002 mm = 42.672 mm
Minimum acceptable diameter = 42.67 mm - 0.002 mm = 42.668 mm
Hence, the maximum and minimum acceptable diameter of the golf ball in the factory will be 42.672 mm to 42.668 mm.

Step-by-step explanation:
find the missing inside angle, V:
180° - 120°
60°
so now the total interior angle of triangle is 180°
m∠U + 60° + 50° = 180°
m∠U = 180° - 110°
m∠U = 70°

Can someone please help me out with this ??? I’d appreciate it so much
Answers
Answer:
(0, 1)
Step-by-step explanation:
So with the 2 equations you can either choose which to start with but you need to make the X or Y the opposite from the other equation.
1.
4x + 2y = 2 --> 1( 4x + 2y = 2)
3x - y = -1 --> 2( 6x - 2y = -2)
--
6x + 4x = 10x
2y - 2y = 0 (forced to get rid of)
2 - 2 = 0
Left with:
10x = 0 (Divide both sides by 10 to get X alone)
x = 0
-----------------------------------------------------------
(Choose any ORIGINAL equation)
4x + 2y = 2
4(0) + 2y = 2 (substitute)
Left with:
2y = 2 (divide both sides by 2 to get Y alone)
y = 1
-------------------------------------------------------------
Optional:
Chose the other equation (the oposite from above)
Substitute X and Y in 3x - y = -1
3(0) - (1) = -1
Left with: -1 = -1 (check)

Explain what is Translation, Rotation, and Reflection.
Answers
Answer:
A translation is a type of transformation that takes each point in a figure and slides it the same distance in the same direction.
A rotation means turning around a center.
A reflection is a transformation representing a flip of a figure.
Answer:
See below!
Step-by-step explanation:
Translation: "Sliding": moving a shape without rotating or flipping it.
The shape still looks exactly the same, just in a different place.
Rotation: A circular movement.
Rotation has a central point that stays fixed and everything else moves around that point in a circle.
A "Full Rotation" is 360°
Reflection: Coordinate plane: A point reflected across the x or y axis, or x and y axis.
Coordinate plane, Shapes: A shape that is reflected across the x or y axis, or x and y axis. (Staying at the same coordinates).
Slopes: A slope that is reflected across the x or y, or x and y axis.
