-------------------------
x x
f= -x+3
7x
f= -x+3
7x
Answer:
A.
Step-by-step explanation:
f(x) = (3-x)/7
First we find x in terms of f(x:-.
7f(x) = 3 - x
x + 7f(x) = 3
x = 3 - 7f(x)
Now we replace x by f-1(x) and f(x) by x:
f-1(x) = 3 - 7x.

Find an equation for the perpendicular bisector of the line segment whose endpoints
are (8, 7) and (-4,3)
Answer:
y = -3x + 11.
Step-by-step explanation:
The slope of the given line segment is (3-7)/(-4-8) = -4/-12 = 1/3.
The midpoint of the line has coordinates (8-4)/2, (7+3)/2.
= (2, 5).
The slope of the perpendicular bisector = -1/ 1/3 = -3.
So it's bisector has equation:
y - y1 = m(x - x1)=
y - 5 = -3(x - 2)
y = -3x + 6 + 5
y = -3x + 11.
a line with the slope of -3 passes through (-8, p) and (2, 3p). Find the value of p
Answer:
To find the Slope: Slope Formula: m = y2 −y1 x2 −x1. Given points: P (6,2) and S(3,1) will be our (x1,y1) and (x2,y2) respectively. Hence x1 = 6,y1 = 2,x2 = 3,y2 = 1. Slope(m) = 1 −2 3 −6. ⇒ −1 −3 = 1 3.
Step-by-step explanation:
Answer:
p = -15
Step-by-step explanation:
[tex]-3=\frac{3p-p}{2-(-8)} =\frac{2p}{10}[/tex]
[tex]\frac{2p}{10} =-3[/tex]
[tex]2p=-3(10)[/tex]
[tex]p=\frac{-30}{2}[/tex]

Step-by-step explanation:
Answer:
1.) x = 90 (Right angle)
2.) x = 103 (Obtuse angle)
Step-by-step explanation:
All triangles' angles have a sum of 180°.<90° = Acute, 90° = Right, >90° = Obtuse[tex]1.)\\x+48+42=180\\x+90=180\\x=90\\\\2.)\\x+45+32=180\\x+77=180\\x=103[/tex]
What is the value of x in the equation 2(x−3)+9=3(x+1)+x?
a. x = −3
b. x = −1
c. x = 0
d. x = 3
Answer:
x=0
Step-by-step explanation:
1st Step(Plug in 0 for x): 2(0-3)+9=3(0+1)+x
2nd Step(Simplify): 2*(-3)+9=3*(1)+x
3rd Step(Multiply): -6+9=3+x
4th Step(Add): 3=3+x
5th Step(Subtract 3 from both sides): x=0
For any questions saying what is the value of x in the equation, just plug in one of the options from a,b,c,d. And work from there
4a+3=40 help please!!!!
4a + 3 = 40
---Subtract 3 from both sides

For her grandfather's birthday, Valeria is baking cupcakes. With every egg she can find, she can bake 6 cupcakes.
Write an equation that shows how the total number of cupcakes Valeria can bake, y, depends on the number of eggs she can find, x.
The equation that shows the total number of cupcakes that Valeria can bake will be y = 6x.
Number of cupcakes that can be baked with 1 egg = 6
Let the total number of eggs be represented by x.
Let the total number of cupcakes be represented by y.
Therefore, the total number of cupcakes will then be:
y = 6 × x
y = 6x
Therefore, the equation that shows the total number of cupcakes that Valeria can bake will be y = 6x.

you walk into a room.on the bed,there 2 dogs, 4 cat, a girrafe, 5 cows and a duck.there are also three chickens flying above the bed.how many legs are on the floor ?
Answer:
50 legs
Step-by-step explanation:
We know that a dog has 4 legs, a cat has 4 legs, a giraffe has 4 legs, a duck has 2 legs, and a chicken has 2 legs. So, we want to calculate [tex]2(4)+4(4)+1(4)+5(4)+1(2)+3(2)[/tex], right?
Wrong! It's a trick question! The chickens aren't on the floor, so they don't count. So, we really want [tex]2(4)+4(4)+1(4)+5(4)+1(2)[/tex].
We multiply it out to get [tex]8+16+4+20+2[/tex].
We add these up to get [tex]50[/tex].
So, our answer is [tex]\boxed{50}[/tex] legs.
Determine whether the ordered pair (0, 2) is a solution to the equation –2x + y = –1.
Answer:
Below.
Step-by-step explanation:
The ordered pair (0, 2) tells us that x = 0 when y = 2.
We just plug these values in the given equation and see if the left side = the right.
Left side = -2(0) + 2 = 2.
Right side = -1.
- so they are not a solution.
Select all that apply. To create perpendicular lines, I can transform a line by:
1. Rotating the line 270° around any point.
2. Translating the line horizontally.
3. Rotating the line 45° around any point, then rotating it another 45° around any point.
4. Translating the line vertically.
5. Reflecting the line over itself.
6. Rotating the line 45° around any point.
7. Reflecting the line over any point on the line.
8. Rotating the line 90° around any point.
Answer:
8. Rotating the line 90° around any point.
Step-by-step explanation:
Perpendicular lines intersect each other at a right angle. Therefore, the transformation should create an image that intersects the preimage at an angle of 90∘. Since a rotation changes the angle between the preimage and the image, it can create perpendicular lines.
