Answer:
In general, a relationship f (x) = y is a function only if, for each value of x that you plug into it, you get only one value for y.
Step-by-step explanation:
Sometimes the only way to tell if a given relationship is a function or not is to try various values for x to see if they yield unique values for y.
Please simplify! 1+x-1+12x=12x-3
Answer:
x = - 3
Step-by-step explanation:
1 + x - 1 + 12x = 12x - 3
Subtract 12x from both sides.
1 + x - 1 = - 3
Combine like terms on the left side.
x = - 3
Answer:
1+x-1+12x=12x-3
Step-by-step explanation:
x+12x-12x=-3-1+1
x=-3
If LMP = (6x+5), NMP = (4x +18) and NML = 163°, find the measure of PMN. im sorry i dont understand geometry at all can someone help?
Answer:
PMN = 74°
Step-by-step explanation:
1. 6x + 5 + 4x + 18 = 163°
2. Combine like terms
3. 10x + 23 = 163°
4. Subtract 23 from both sides.
5. 10x = 140°
6. Divide 10 from both sides.
7. x = 14°
8. Now substitute the x in the equation for PMN with 14.
9. 4(14) + 18
10. Simplify
11. 56 + 18
12. Answer: 74°
Please I need help....
Answer:
1. D
"n" represents the figure. For example, the equation for figure 3 would be [tex]\frac{3(3+1)}{2}[/tex] which is equal to 6 (the amount of blocks in the figure).
2. D
In the sample equations, the 9 represents figure 9. There are consistently 3 blocks in each row with an additional block at the top of the figures. So, the equation for figure 4 would be 1+(3x4) which is equal to 13. Therefore, the equation for figure 9 would be 1+(3x9).
3. A
P represents the perimeter and the n represents the figure number (like in question 1). The correct equation for the pattern would be P=4n+8. To check it, we can plug the numbers from figure 2. The equation would look like this: 16=4(2)+8
4. B
To find the answer to this problem, we just have to work backwards. We must "divide a number by 5" so we start out with [tex]\frac{n}{5}[/tex]. "n" represents the number that we do not know yet. Then we must "add 4 to the result" so the equation will now look like this: [tex]\frac{n}{5} + 4[/tex]. The problem also states that the answer is 9. Now, the final equation looks like this: [tex]\frac{n}{5} + 4=9[/tex].
If you need to, guess and check is a good way to complete multiple choice questions (until you're able to get help). I recommend asking your teacher for a more in depth explanation if you still don't understand.

The first aircraft has 89 more seats than the second aircraft. The third aircraft has 31 fewer seats than the second aircraft. If their total number of seats is 418, find the number of seats for each aircraft.
Answer:
I think number 1=209
number 2=120
number 3=89
Step-by-step explanation:
x= 1st aircraft
y=2nd aircraft
z=3rd aircraft
x=y+89
y=z+31
z=y-31
x+y+z=418
y+89+z+31+y-31=418
2y+89+z=418
2y+z=329
2y+(add z)
2y+y-31=329
3y=360
y=120
x=120+89=209
z=120-31=89

Step-by-step explanation:
M is the midpoint of segment AB and M (-4,-5) and A (-2,-9) find the endpoint B.
(-6, -1) b) (4,-1) c) (-2,4) d) (4,2)
The midpoint of a line segment divides a line segment into two equal parts. (T/F).
Answer:
(-6, -1)
Yes, the midpoint of a line segment divides the segment into two equal parts. True.
Step-by-step explanation:
Going from A(-2, -9) to M(-4, -5), x decreases by two units from -2 to -4; if we now go from M(-4, -5) to B, we expect that x will decrease by two more units, from -4 to -6. Thus, the x-coordinate of B is -6.
y increases by 4 from -9 to -5 (4 units) under the same circumstances. To find the y-coordinate of B, we add 4 to -5, obtaining y = -1.
The endpoint B is thus (-6, -1).
Kira owes Mark $5, and Mark owes Kira $7. Which of the following statements means the same thing?
Answer:
Mark owes Kira $2.
Step-by-step explanation:
The correct answer is “Mark owes Kira $2” because first Kira owes $5 to the Mark and then Mark gives $7 to Kira. Here it can be seen that Mark is giving $2 extra and $5 is the amount which he is refunding. So the net amount $2 that the Mark gives to Kira. Therefore, the statement “Mark owes Kira $2” is justified and correct.

The sum of the angles of a triangle is 180
70+60+8x+2 = 180
Combine like terms
132 +8x = 180
Subtract 132 from each side
132+8x-132= 180-132
8x = 48
Divide each side by 8
8x/8 = 48/8
x = 6

2/5 as a decimal show all work
Answer:
0.4
Step-by-step explanation:
to convert from a fraction to a decimal, we first have to make the denominator 100
we know that 5 goes into 100 20 times ;
100 ÷ 5 = 20 ;
then we have to multiply the numerator by 20 as well because we have multiplied the bottom by 20 ;
[tex]\frac{2}{5}[/tex] [tex](\frac{20}{20})[/tex]
2 x 20 = 40 ;
= [tex]\frac{40}{100}[/tex]
then to convert this into a decimal, divide the numerator by the denominator
40 ÷ 100 = 0.4

help!! Find the equation of the line shown
Answer:
[tex]\boxed{\bold{\huge{\boxed{y = 2x}}}}[/tex]
Step-by-step explanation:
Slope(m):
To find the slope , we need to take any two coordinates from the line.
The coordinates are (0,0) and (5,10)
Slope = [tex]\sf \frac{rise}{run}[/tex]
Slope = [tex]\sf \frac{y2-y2}{x2-x1}[/tex]
Slope = [tex]\frac{10-0}{5-0}[/tex]
Slope = [tex]\frac{10}{5}[/tex]
Slope = 2
Y-intercept(b):
Y-intercept is the point where x = 0 and that point is the origin.
So, y-intercept = 0
Slope-intercept equation:
[tex]\sf y = mx+b[/tex]
Where m = 2 and b = 0
[tex]\sf y = 2x+0[/tex]
[tex]\sf y = 2x[/tex]
