what is the answer to the question 1/2n+5=3?
9 - 6(x+1) = 2(x-4) + 27
Solve each equation and show all your work.
6x - 5 = 2x + 7
3z - 2 = 5z + 19
5x - 15 + 2x = 4x + 12
35x + 2 = 7
Answer:
x = 3
z = (-21)/2
x = 9
x = 1/7
Step-by-step explanation:
Solve for x:
6 x - 5 = 2 x + 7
Subtract 2 x from both sides:
(6 x - 2 x) - 5 = (2 x - 2 x) + 7
6 x - 2 x = 4 x:
4 x - 5 = (2 x - 2 x) + 7
2 x - 2 x = 0:
4 x - 5 = 7
Add 5 to both sides:
4 x + (5 - 5) = 5 + 7
5 - 5 = 0:
4 x = 7 + 5
7 + 5 = 12:
4 x = 12
Divide both sides of 4 x = 12 by 4:
(4 x)/4 = 12/4
4/4 = 1:
x = 12/4
The gcd of 12 and 4 is 4, so 12/4 = (4×3)/(4×1) = 4/4×3 = 3:
Answer: x = 3
____________________________________
Solve for z:
3 z - 2 = 5 z + 19
Subtract 5 z from both sides:
(3 z - 5 z) - 2 = (5 z - 5 z) + 19
3 z - 5 z = -2 z:
-2 z - 2 = (5 z - 5 z) + 19
5 z - 5 z = 0:
-2 z - 2 = 19
Add 2 to both sides:
(2 - 2) - 2 z = 2 + 19
2 - 2 = 0:
-2 z = 19 + 2
19 + 2 = 21:
-2 z = 21
Divide both sides of -2 z = 21 by -2:
(-2 z)/(-2) = 21/(-2)
(-2)/(-2) = 1:
z = 21/(-2)
Multiply numerator and denominator of 21/(-2) by -1:
Answer: z = (-21)/2
________________________________________
Solve for x:
5 x + 2 x - 15 = 4 x + 12
Grouping like terms, 5 x + 2 x - 15 = (5 x + 2 x) - 15:
(5 x + 2 x) - 15 = 4 x + 12
5 x + 2 x = 7 x:
7 x - 15 = 4 x + 12
Subtract 4 x from both sides:
(7 x - 4 x) - 15 = (4 x - 4 x) + 12
7 x - 4 x = 3 x:
3 x - 15 = (4 x - 4 x) + 12
4 x - 4 x = 0:
3 x - 15 = 12
Add 15 to both sides:
3 x + (15 - 15) = 15 + 12
15 - 15 = 0:
3 x = 12 + 15
12 + 15 = 27:
3 x = 27
Divide both sides of 3 x = 27 by 3:
(3 x)/3 = 27/3
3/3 = 1:
x = 27/3
The gcd of 27 and 3 is 3, so 27/3 = (3×9)/(3×1) = 3/3×9 = 9:
Answer: x = 9
__________________________________________
Solve for x:
35 x + 2 = 7
Subtract 2 from both sides:
35 x + (2 - 2) = 7 - 2
2 - 2 = 0:
35 x = 7 - 2
7 - 2 = 5:
35 x = 5
Divide both sides of 35 x = 5 by 35:
(35 x)/35 = 5/35
35/35 = 1:
x = 5/35
The gcd of 5 and 35 is 5, so 5/35 = (5×1)/(5×7) = 5/5×1/7 = 1/7:
Answer: x = 1/7

A field's length l(x), in feet, can be represented by the expression x+10 and its width w(x), in feet, can be represented by the expression x+15. Which function represents its area?
A) x^2+25x+150
B) 4x+50
C) 2x+25
D) x^2+10x+150
Answer:
A) x^2+25x+150
Step-by-step explanation:
Area = length x width
A = (x + 10) x (x + 15)
A = x^2 + 25x + 150

−x+y=−5
What is the value of the x-intercept?
What is the value of the y-intercept?
Remember when finding the x-intercept you cover up the y (put 0 in for y) and solve for the x value.
Answer:
see below
Step-by-step explanation:
−x+y=−5
To find the x intercept, let y=0 and solve for x
-x +0 = -5
-x = -5
x=5
The x intercept is 5
To find the y intercept, let x=0 and solve for y
0 +y = -5
y = -5
The y intercept is -5

Answer:
Add the information, and find the second number.
Step-by-step explanation:
"She throws them 8.49 m/s high"
8.49 + ? = ?
"Her friend catches them 2.89 m/s higher"
8.49 - 2.89 = 5.60
The reason why you must subtract is because it is asking how high it is in the air, going up and down.
8.49 + 5.60 = ?
8.49 + 5.60 = 14.09
Which means, it was in the air for 14.09 m/s.
Consider the diagram.
Lines AC and RS can best be described as
intersecting.
parallel.
perpendicular.
skew.
Answer:
Scew option D
Step-by-step explanation:
I have the same test
When lines are not parallel, and they do not intersect, such lines are said to be skewed.
Line AC and RS are skew.
From the diagram, we have two planes.
Plane x Plane yLine AC is on plane x, while line RS is on plane y.
This means that both lines are non-coplanar
Planes x and y are not parallel; so lines AC and RS are not parallel.
Using the condition of skewness stated above, we can conclude that line AC and RS are skew.
See attachment for plane x and plane y

Let the graph of g be a horizontal shrink by a factor of 1/6 and a reflection in the x-axis, followed by a translation 2 units down of the graph of f(x)=x^2. write a rule for g.
Answer:
Step-by-step explanation:
A function s is the HORIZONTAL SHRINK of a function h by a factor k
if s(x) = h(kx)
It is called a shrink, because for k > 1 that has the effect of compressing
the function h towards the y-axis.
I find the problem statement a little confusing because
using k = 1/6 would result in stretching, not shrinking.
Therefore my guess is that the author means k = 6.
A function r is a REFLECTION of a function h in the x-axis
if r(x) = -h(x).
The reason is that r looks like a mirror image of h,
where the mirror is the x-axis.
A function t is a TRANSLATION 2 units down of a function h
if t(x) = h(x) - 2.
The graph of t looks like h, except shifted down 2 units.
Applying the definitions to your function f:
g(x) = -f(6x) - 2 = -36x^2 - 2

you start hiking at an elevation that is 550 meters below sea level.you increase your elevation by 45 meters.what is the new elevation? write an addition and evaluate.
Answer:
-550+45=(-505)
Step-by-step explanation:
You are at -505 meters below sea level
Answer:
You are now 38 m below base camp.
Step-by-step explanation:
Consider the provided information.
You start hiking at an elevation that is 80 meters below base camp.
Now your initial location is 80 m below base camp, that can be represents as: -80
Now you increase your elevation by 42.
So you go up by 42.
In other words, you get the equation -80+42 = -38.
Since, a negative value is below the base camp, this means that you are now 38 m below base camp.
