Answer (first one):
[tex]{x|-2\leq x\leq 8}[/tex]
Step-by-step explanation:
think of f(x) as y.
[tex]y>-2[/tex]
Now find the parts on the x axis that correspond with parts on the y value that are greater than -2.
[tex]x\geq -2 \\x \leq 8[/tex]
This would be all of the numbers between -2 and 8 (inclusive).
The reason it is inclusive is because the arrow ends are shaded in.

is 3 a solution of 5x - 3= 12? justify your answer
Answers
Answer:
x = 3
Step-by-step explanation:
Given
5x - 3 = 12 ( add 3 to both sides )
5x = 15 ( divide both sides by 5 )
x = 3
As a check
Substitute x = 3 into the left side of the equation and if equal to the right side then it is a solution.
5(3) - 3 = 15 - 3 = 12 = right side
Thus x = 3 is the solution
-140 = -2(8r + 6) sorry prob just a few more questions i think
Answers
Answer:
r=8
Step-by-step explanation:
so first distribute -2
so you get -140=-16r-12 then add 12 to both sides to get -16r by itself
so you have -128=-16r divide both sides by -16
the - cancel each other out so you get 8=r

Answers
Answer:
C=6p
Step-by-step explanation:
The cost (c) will be by itself since that is the answer you are looking for. 6p is grouped together because for every pound you pay $6. For example if you had 2 pounds of chocolate. You would multiple $6 by 2 and your cost would equal $12
Answer:
c=6p

Answer:
It takes Sharon 1 hour to paint by herself.
Step-by-step explanation:
if it takes 1 hr and 30 mins for the two to finish it together that means that's the average of both Mel and Sharon's time.
So multiply 1 hr and 30 mins by 2 (since there are two people)
that gives us 3 hrs, in which we subtract Mel's two hours.
It takes Sharon 1 hour to paint by herself.

21+ 6m=3(m-1) not sure what to do here
Answers
Answer:
M=-8
Step-by-step explanation:
21+6m=3(m−1)
Step 1: Simplify both sides of the equation.
21+6m=3(m−1)
21+6m=(3)(m)+(3)(−1)(Distribute)
21+6m=3m+−3
6m+21=3m−3
Step 2: Subtract 3m from both sides.
6m+21−3m=3m−3−3m
3m+21=−3
Step 3: Subtract 21 from both sides.
3m+21−21=−3−21
3m=−24
Step 4: Divide both sides by 3.
3m/3=-24/3
M=-8
Answer:
m = - 8
Step-by-step explanation:
Given
21 + 6m = 3(m - 1) ← distribute
21 + 6m = 3m - 3 ( subtract 3m from both sides )
21 + 3m = - 3 ( subtract 21 from both sides )
3m = - 24 ( divide both sides by 3 )
m = - 8

help asap with domain and range.
Answers
Answer:Overall, the steps for algebraically finding the range of a function are:
Write down y=f(x) and then solve the equation for x, giving something of the form x=g(y).
Find the domain of g(y), and this will be the range of f(x).
If you can't seem to solve for x, then try graphing the function to find the range.

Insert two arithmetic means between 21 and 33
Answers
Answer:
25 and 29
Step-by-step explanation:
let the two arithmetic mean be b and c respectively.
U(1)=21 and since it is the first term then, a=21
2nd term that is U(2)=b
3rd term that is U(3)=c
4th term that is U(4)=33
Now U(2)=(a+d) that is b
U(3)=(a+2d) that is c
U(4)=(a+3d) that is the 4th term
find d using the 4th term
a+3d=33
21+3d=33
3d=33-21
3d=12
d=12÷33
d=4
therefore
b= a+d ( second term)
b=21+4
b=25
then
c=a+2d ( 3rd term )
c=21+2×4
c=21+8
c=29
The two arithmetic means between 21 and 33 are 25 and 29.
What is the arithmetic mean?The sequence in which every next number is the addition of the constant quantity in the series is termed the arithmetic progression.
let the two arithmetic mean be b and c respectively.
U(1)=21 and since it is the first term then, a=21
2nd term is U(2)=b
3rd term is U(3)=c
4th term that is U(4)=33
Now U(2)=(a+d) that is b
U(3)=(a+2d) is c
U(4)=(a+3d) that is the 4th term
find d using the 4th term
a+3d=33
21+3d=33
3d=33-21
3d=12
d=12÷33
d=4
The second term will be:-
b= a+d ( second term)
b=21+4
b=25
The third term will be:-
c=a+2d ( 3rd term )
c=21+2×4
c=21+8
c=29
Therefore, the two arithmetic means between 21 and 33 are 25 and 29.

Answers
Answer:
(-1/2,15/2)
Step-by-step explanation:
let(-4,7)=(x1,y1)
(3,8)=(x2,y2)
Then,
Using midpoint formula,
Midpoint(x,y)=((x1+x2)/2,(y1+y2)/2)
=((-4+3)/2,(7+8)/2)
=(-1/2,15/2)
Thus,midpoint(x,y)=(-1/2,15/2)

1. Given line segment RB and on it is point C, if RB = 45 and CB = 3x - 12 and RC = 2x + 9, what is the value of x?
2. Using the same problem and values above, what is the length of line segment RC?
3.Use the coordinate plane/graph for the third problem.
Find the distance between A and D. Round your answer to the nearest hundredth place. *
Answers
Answer:
Step-by-step explanation:
1). If a point C is lying on a line segment RB,
Then RB = RC + CB
Since, RB = 45, CB = 3x - 12 and RC = 2x + 9
45 = (2x + 9) + (3x - 12)
45 = (2x + 3x) - 3
48 = 5x
x = [tex]\frac{48}{5}[/tex]
x = 9.6
2). Since, RC = 2x + 9
RC = 2(9.6) + 9
= 19.2 + 9
= 28.2 units
3). Distance between the two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by the formula,
d = [tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Distance between the points A(2, -2) and D(-2, 2) will be,
[tex]AD=\sqrt{(2+2)^2+(-2-2)^2}[/tex]
= [tex]\sqrt{16+16}[/tex]
= [tex]4\sqrt{2}[/tex]
= 5.657
≈ 5.66 units
