What is the answer to this math question “X - 3 = 6”
Answer: x = 9
Step-by-step explanation:
x can be equal to 9.
Lets plug in 9 to the variable x, in this equation, x -3 = 6.
x - 3 = 6
9 - 3 = 6 (plugged in 9 for x)
So, x = 9.
Answer:
x-3=6
The correct answer is x=9
Step-by-step explanation:
9-3=6

Step-by-step explanation:
The medians of TUV are TX, UY, and VW. They meet at a single point Z.
(In other words, Z is the centroid of TUV.)
Suppose UZ=8, VW=33, and ZX=5.
Find the following lengths.
Note that the figure is not drawn to scale.
Answer:
TZ = 10 units
UY = 12 units
ZW = 11 units
Step-by-step explanation:
Point Z is the centroid of ΔTUV.
Since, centroid of a triangle is located on each median so that it divides each median in the ratio of 2 : 1
Therefore, TZ = 2(ZX)
TZ = 2(5) = 10 units
UY = UZ + ZY
= UZ + [tex]\frac{1}{2}(UZ)[/tex]
= [tex]\frac{3}{2}UZ[/tex]
= [tex]\frac{3}{2}\times 8[/tex]
= 12 units
ZW = [tex]\frac{1}{3}(VW)[/tex]
= [tex]\frac{1}{3}(33)[/tex]
= 11 units

what is the y intercept of a line that passes through (1,-7) and (5,-25). How do I find it.
Answer:
y- intercept = - 2.5
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (1, - 7) and (x₂, y₂ ) = (5, - 25)
m = [tex]\frac{-25+7}{5-1}[/tex] = [tex]\frac{-18}{4}[/tex] = - 4.5 , then
y = - 4.5x + c
To find c substitute either of the 2 points into the equation
Using (1, - 7), then
- 7 = - 4.5 + c ⇒ c = - 7 + 4.5 = - 2.5
y- intercept c = - 2.5

Given:
The increase in pressure P is the linear function of the depth d.
[tex]P(d)=0.445d+14.7[/tex]
The cost of dinner is $300 and $10 per students.
To find:
The initial value and rate of change and their interpretation.
Find the cost function C where n is the number of students.
Solution:
The slope intercept form of a linear function is
[tex]f(x)=mx+b[/tex] ...(i)
where, m is rate of change and b is y-intercept or initial value.
We have,
[tex]P(d)=0.445d+14.7[/tex] ...(ii)
From (i) and (ii), we get
[tex]m=0.445,b=14.7[/tex]
The initial value is 14.7. It means, the pressure at sea level is 14.7 pounds psi.
Rate of change is 0.445. It means, the pressure is increasing by 0.445 pounds psi for every feet.
The cost of dinner is $300 and $10 per students.
Let C(n) be the total cost for dinner and n be the number of students.
Fixed cost = $300
Additional cost for 1 student = $10
Additional cost for n student = $10n
Now,
Total cost = Fixed cost + Additional cost
[tex]C(n)=300+10n[/tex]
Therefore, the required cost function is [tex]C(n)=300+10n[/tex].

Derek bought a cloth for rs 950 .He spent rs 150 for stitching a shirt and sold it at a gain of rs 375 . Find the selling price of the shirt
Answer:
$1473
Step-by-step explanation:
cost of cloth= rs.950
He spent rs.150 for stitching a shirt
total cots= 950+150
total cost=1100
gain= rs.375
we know that
gain= selling price- cost price
substitute
375= selling price- 1100
selling price= 1100+373
selling price=$1473
Hence the selling price is $1473

What is an equation of the line that passes through the point (6,7) and is parallel to the line 2x-3y=92x−3y=9?
Answer:
y = ²/₃x + 3Step-by-step explanation:
y=m₁x+b₁ ║ y=m₂x+b₂ ⇔ m₁ = m₂
{Two lines are parallel if their slopes are equal}
Changing to slope-intercept form:
2x - 3y = 9 {subtract 2x from both sides}
-3y = -2x + 9 {divide both sides by (-3)}
y = ²/₃x - 3 ⇒ m₁=²/₃ ⇒ m₂=²/₃
The line y=²/₃x+b passes through point (6, 7) so the equation:
7 = ²/₃×6 + b is true
7 = 4 + b
b = 3
Therefore equation in slope-intercept form:
y = ²/₃x + 3
The equation of the line passing through the point (6, 7) parallel to the line is y = 2/3x + 3
The equation in slope - intercept form :
2x - 3y = 9
-3y = 9 - 2x
Divide both sides by - 3
y = - 3 + 2/3x
Using the points (6, 7)
7 = c + 2/3(6)
7 = c + 12/3
7 = c + 4
c = 7 - 4 = 3
c = 3
The equation of the parallel line is thus :
y = 2/3x + 3Learn more : https://brainly.com/question/18106342

Answer:
Option A. – 3
Step-by-step explanation:
From the question given above, the following data were obtained:
y = 3/4
xy² = 9/16
(x – 4) =?
Next, we shall determine the value of x. This can be obtained as follow:
y = 3/4
xy² = 9/16
x(3/4)² = 9/16
x (9/16) = 9/16
Divide both side by 9/16
x = 9/16 ÷ 9/16
x = 1
Finally, we shall determine the value (x – 4). This can be obtained as follow:
(x – 4)
x = 1
(x – 4) = 1 – 4
= – 3

Answer:
(-2, -4)
Step-by-step explanation:
Since both equations are equal to y, you can set them equal to each other:
[tex]\frac{3}{2}x-1=\frac{1}{2}x-3[/tex]
Next, solve for x:
[tex]\frac{3}{2}x-1=\frac{1}{2}x-3\\x-1=-3\\x=-2[/tex]
Finally, substitute the solution for x in one of the equations (or both) to find y:
[tex]y=\frac{3}{2}(-2)-1\\y=-3-1\\y=-4[/tex]
[tex]y=\frac{1}{2}(-2)-3\\y=-1-3\\y=-4[/tex]
Therefore, the solution to the system of equations is (-2, -4).
