Answer:
1. f(a) = -2a + 3
2. 2f(a) = -4a + 6
3. f(2a) = -4a + 3
4. f(a+2) = -2a - 1
5. f(a) + f(2) = -2a + 2
Step-by-step explanation:
for each one, just plug whatever is inside the parentheses inside the equation as x. For example, f(a) = -2(a) + 3. The a replaces all the x's
Can someone please help me out with this ??? I’d appreciate it so much
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)
Hope this helps
Find the equation of the line determined by the given information.
10.m= 1; P = (-7, 0)
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

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.
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
Calculate the equation of the following line.
Answer:
point-slope form: [tex]y+1=\frac{-3}{2}(x-3)[/tex]
slope-intercept form: [tex]y=\frac{-3}{2} x+\frac{7}{2}[/tex]
Step-by-step explanation:
find the slope of the line using two points on the graph, and then you can get your equation in point-slope form. if you need it in slope-intercept form, you can re-arrange your point-slope form equation.

The sales tax for an item was $26.60 and it cost $380 before tax. Find the sales tax rate. Write your answer as a percentage.
Answer:
7% sales tax
Step-by-step explanation:
Given the following question:
Sales tax = $26.60
It costs $380 before tax
In order to find the answer, we simply find a random percentage of the original cost before tax.
[tex]\frac{7\times380}{100} =2660\div100=26.6=26.60[/tex]
7% sales tax rate.

Answer:
70
Step-by-step explanation:
180-120=60
180-(60+50)=70
Answer:
m∠U = 70°
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°

Each pepper or product of pepper costs $4.75
So the unit rate is 4.75/pepper
The unit rate is considered as the slope of the line, or also known as the constant or proportionality. As the Number of peppers increase, the price increases proportionally.
The constant of proportionality is 4.75

Explain what is Translation, Rotation, and Reflection.
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.

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
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.
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.
