If triangle PML ~ triangle TRQ, find QR.
im stuck on the same problem
The measure of QR, from the triangle TRQ is 16 units.
What are similar triangles?Two triangles are similar if the angles are the same size or the corresponding sides are in the same ratio. Either of these conditions will prove two triangles are similar.
Given that, triangle PML is similar to triangle TRQ.
From the given triangles.
ML/QR =PM/TR
(7x-9)/(2x+2) = 35/14
(7x-9)/(2x+2) = 5/2
2(7x-9)=5(2x+2)
14x-18=10x+10
4x=28
x=7
Then, QR=2x+2=16 units
Therefore, the measure of QR is 16 units.

Using the graph, determine the equation of the axis of symmetry
Answer:
-5 or (-5,0)
Step-by-step explanation:
The axis of symmetry of a parabola is a vertical line that divides the parabola into two congruent halves. The axis of symmetry always passes through the vertex of the parabola . The x -coordinate of the vertex is the equation of the axis of symmetry of the parabola.
The solution is : the equation of the axis of symmetry is x= -5 or (-5,0).

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: 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:

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

hello i would like help and the answer to this please; what is the nth term rule of
-5 -4 -1 4 1 1 20 31
Answer:
The nth term of the given sequence
[tex]a_{n} = a_{n-1} + (2n-1)[/tex]
Step-by-step explanation:
Explanation:-
Given sequence -5,-4,-1,4,11,20,31
a₀ = -5
a₁ = a₀ +1 = -5 +1 = -4
a₂ = a₁ + 3 = -4+3 = -1
a₃ = a₂ + 5 = -1 +5 = 4
a₄ = a₃ + 7 = 4 + 7 =11
a₅ = a₄ + 9 = 11+9 = 20
a₆ = a₅ + 11 = 20+11 = 31
a₇ = a₆ + 13 = 31 +13 =44
and so on
The nth term of the given sequence
[tex]a_{n} = a_{n-1} + (2n-1)[/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
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
