Step-by-step explanation:
Answer:
x = 8 and x = 7
Step-by-step explanation:
(6)
Since the triangles are similar then the ratio of corresponding sides are equal, that is
[tex]\frac{ST}{MN}[/tex] = [tex]\frac{RS}{LM}[/tex] , substitute values
[tex]\frac{x}{4}[/tex] = [tex]\frac{4}{2}[/tex] ( cross- multiply )
2x = 16 ( divide both sides by 2 )
x = 8
(7)
Since the prisms are similar then the ratio of corresponding sides are equal, that is
[tex]\frac{x}{35}[/tex] = [tex]\frac{2}{10}[/tex] ( cross- multiply )
10x = 70 ( divide both sides by 10 )
x = 7
The price of Stock A at 9 A.M. Was $15.59 Since then, the price has been increasing at the rate of $0.12 each hour. At noon the price of Stock B was $16.34 It begins to decrease at the rate of $0.11 each hour. If the two rates continue, in how many hours will the prices of the two stocks be the same?
Answer:
Prices of the two stocks A and B become same in 42 hours
Step-by-step explanation:
Let t denotes number of hours in which the prices of the two stocks A and B become same.
Price of stock A = $15.59
Increase in price per hour = $0.12 t
Price of stock B = $16.34
Decrease in price per hour = $0.11 (t - 3)
(since price of stock A starts increasing per hour after 9 A.M. and price of stock B starts decreasing per hour after 12 noon that is 3 hours after 9 A.M.)
To find number of hours in which the prices of the two stocks A and B become same, solve [tex]15.59+0.12t=16.34+0.11(t-3)[/tex]
[tex]15.59+0.12t=16.34+0.11(t-3)\\15.59+0.12t=16.34+0.11t-0.33\\0.12t-0.11t=16.34-0.33-15.59\\0.01t=0.42\\t=42[/tex]
So, prices of the two stocks A and B become same in 42 hours

Which formula represents this sequence 2,8,14...?
Answer:
[tex]a_{n}[/tex] = 6n - 4
Step-by-step explanation:
There is a common difference between consecutive terms in the sequence, that is
8 - 2 = 14 - 8 = 6
This indicates the sequence is arithmetic with n th term
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 2 and d = 6 , thus
[tex]a_{n}[/tex] = 2 + 6(n - 1) = 2 + 6n - 6 = 6n - 4
Thus the formula representing the sequence is
[tex]a_{n}[/tex] = 6n - 4

Step-by-step explanation:
Answer:
IF YOU HAVE TO SOLVE FOR Y THEN TAKE X AS ANY NUMBER YOU WANT.
SUPPOSE X=2
PUT THE VALUE IN THE EQUATION THEN U WILL GET-
Y+2(2)=5
= Y+4=5
= Y=5-4
= Y=1
THIS IS JUST ONE EXAMPLE BUT THERE CAN BE INFINITIVE NUMBER OF ANSWERS FOR THIS QUESTION.
I WILL SHOW U ONE MORE EXAMPLE.
IF X=1
THEN THE EQUATION WILL BE-
Y+2(1)=5
Y+2=5
Y=5-2
Y=3
SO HERE WE GOT Y=1&3
AND ALSO Y CAN HAVE INFINITE SOLUTIONS (THIS IS ON THE BASIS OF THE PROPERTY OF LINEAR EQUATION, I.E., A LINEAR EQUATION CAN HAVE INFINITIVE SOLUTIONS)

What is the equation in slope-intercept form of the line that passes through the points ( -4, 47) and ( 2 , -16)?
ANSWER CHOICES BELOW...ANSWER CORRECTLY PLZ TAKING INTERIM NOW
Answer:
C
Step-by-step explanation:
Slope intercept form equation is y=mx+b
M=Slope
Slope equation is y2-y1 over x2-x1
So -16 - 47 over 2- (-4)
-63 over 6
Divide by 3 to simplify
= -21 over 2
Keep that as your answer for slope because a mixed number can't be used for slope but an improper fraction is perfectly fine
To find b use one point given (I chose to use (2, -16)
Plug that in and your slope to find b
-16= -21/2 (2) +b
-16= -21+b
+21 +21
5=b
Now plug that in and youre done
Y= -21/2x + 5

select the construction that guaranties A is a reflection of point A across line BC
Answer:
I think it's Axial Symmetry.
Step-by-step explanation:
You draw a perpendicular line to the line BC through A.You get your compass and set it to the distance between the point A and the line BC. Using that distance on your compass, put the point of your compass on the point where the perpendicular line and BC intersect. Mark the distance on the perpendicular line. The reflection is the point you mark on the perpendicular line.hurry !!! i’m so confused!

What is an equation of the line that passes through the point
(-6, – 7) and is perpendicular to the line 6x + 5y = 30?
HELP!!!
Answer:
(y+7)=5/6(x+6)
Step-by-step explanation:
For this problem we need to use Point-Slope Form to write an equation.
We already have the point, (-6,-7), so all we need now is the slope, which we know is perpendicular to the line 6x+5y=30.
First, let's find the slope of 6x+5y=30 by converting it into Slope-Intercept Form, which is y=mx+b. m is the slope.
6x+5y=30
5y=-6x+30
y=-6/5x+6
So the slope of this line is -6/5, but we need the slope of the line is perpendicular to this line.
When a line is perpendicular to another, their slopes are negative reciprocals to one another, or opposite reciprocals. For example, a line that is perpendicular to another line that has a slope of 3/4 will have a slope of -4/3. Flip the numerator and denominator to find the reciprocal and add a negative.
x
So the negative reciprocal of -6/5 is 5/6, so that is our slope.
Now we can assemble our equation, here is the Point-Slope Form:
[tex](y -y_{1}) =m(x-x_{1})[/tex]
again, m is our slope.
[tex]y_{1}[/tex] and [tex]x_{1}[/tex] represent the coordinates of the point that this line passes through, (-6, -7).
Let's plug in the y, x, and m values:
(y-(-7))=5/6(x-(-6))
Simplify:
(y+7)=5/6(x+6)
That is our final answer.

An equation is formed of two equal expressions. The unknown number is 1.
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
Let the unknown number be represented by x.
The given statement can be written in the form of an equation as shown below.
Twice of a number → 2xSum of twice a number and six → 2x + 6Four-time the sum of twice a number and six → 4(2x + 6)Four-time the sum of twice a number and six is thirty-two→ 4(2x + 6) = 32
The given equation can be solved as shown below.
4(2x + 6) = 32
Open the parenthesis by multiplying 4 inside the parenthesis,
8x + 24 = 32
Subtract 24 on both sides of the equation,
8x + 24 - 24 = 32 - 24
8x = 8
Divide both sides of the equation by 8,
8x/ 8 = 8/8
x = 1
Hence, the unknown number is 1.

X = 20 degrees
Step-by-step explanation:
so we know that a triangle equals 180 degrees.
We already have 70 degrees so there are 110 degrees left.
Y is a right angle making it a 90 degree angle
110-90 equals 20 making x a 20 degree angle.
How many solutions does the following equation have?
23y+50+27y=50y+50
Find the acute angle between the lines whose slopes are 2 & 1\3.
Answer:30 degrees
Step-by-step explanation:There are a couple of ways to do this.
This is the straightforward, “follow-your-nose” way. Find a point on each line. (Say, (1,2) on the line with slope 2 and (-1,1) on the line with slope -1. Then the angle in the triangle formed by the origin (0,0) and these other two point is the desired angle. One can find the cosine of angle in the triangle using the Law of Cosines, since the lengths of all of the sides can be found directly from the distance formula and the coordinates of the points. Finally, use arccosine to get from the cosine of the angle to the angle itself.
There is also a “slick” way, which relies on remembering the subtraction formula for tangents. tan(u-v) = [tan(u) - tan(v)] / [tan(u) + tan(v)]. Consider u as the angle between the positive x-axis and the line with slope -1, and v as the angle between the positive x-axis and the line with slope 2. Then the requested angle is u-v. We know tan(u) = -1 and tan(v) = 2, so substituting into the subtraction formula for tangents allows us to find tan(u-v). Finally, use arctangent of that value to find u-v.

1. Point M is on PQ, PM has a length of 7 units, and point N is the midpoint of MQ. If the length of NQ
is 4 units, how long is PQ?
PA
A 3 units
B. 11 units
C. 15 units
D. 18 units
Answer:
C. 15 units
Step-by-step explanation:
PM = 7 units
p..............M..........N............Q
7 unit 4 unit
NQ = 4 units
Given that
N is midpoint of MQ
it means N divides MQ into two equal parts
thus
MN = NQ = 4 units
now
we have to find length of PQ
p..............M..........N............Q
7 unit 4 units 4 unit
PQ = PM + MN + NQ
PQ = 7 units + 4 units + 4 units = 15 units
thus, correct answer is option c 15 units
