Answer:
The number is 4
Step-by-step explanation:
Let the number be n
Twice the number : 2*n = 2n
Half the number : 1/2 n
[tex]2n+ \frac{n}{2}=10\\\\\frac{2n*2}{2}+\frac{n}{2}=10\\\\\frac{4n}{2}+\frac{n}{2}=10\\\\\frac{5n}{2}=10\\\\5n=10*2\\\\5n=20\\\\n=\frac{20}{5}\\\\[/tex]
n = 4
What is the image point of (7,-5)after a translation right 3 units and down 1 unit?
Answer:
(10, - 6)
Step-by-step explanation:
P = (7, - 5)
T(P) = [x +3, y + (-1)]
T(P) = [7 +3, - 5+ (-1)]
T(P) = [7 +3, - 5 -1]
T(P) = (10, - 6)
The translated coordinates of the points (7,-5) will be (10, 2).
What are transformations?Two-dimensional figures can be transformed mathematically in order to travel about a plane or coordinate system.
Dilation: The preimage is scaled up or down to create the image.
Reflection: The picture is a preimage that has been reversed.
Rotation: Around a given point, the preimage is rotated to create the final image.
Translation: The image is translated and moved a fixed amount from the preimage.
The image point of (7,-5)after a translation right 3 units and down 1 unit will be,
= [(7+3), (3-1)].
= (10, 2).

Given a point P on a line with slope m; find the y-coordinate of the point with the given x-coordinate,
P(2,-5)
m=6
X = 3.5
Answer:
y = 4
Step-by-step explanation:
find full equation by plugging in P
y = mx + b
y = 6x + b
-5 = 6(2) + b
-5 = 12 + b
b = -17
y = 6x - 17
find y-value by plugging in x-value to equation
y = 6(3.5) - 17
y = 21 - 17
y = 4
find the measure of angle a
Answer:
[tex]\angle A = 40^o[/tex]
Step-by-step explanation:
Notice that angle A is identified with the algebraic expression "7 + 3 x", while the other acute angle is identified with the expression "5 x - 5"
We know that the third angle is a right angle (90 degrees),
and also that the sum of the internal angles in a triangle must give 180 degrees, so we have:
[tex]\angle A + \angle B+ 90^o = 180^o\\(7+3\,x)+(5\,x-5)=180^o-90^o\\7+3\,x+5\,x-5=90^o\\8\,x+2 = 90^o\\8\,x=88^o\\x=11^o[/tex]
Now that we know x, we can give the answer for what angle A is:
[tex]\angle A= 7^o+3\,x\\\angle A =7^o+3\,(11^o)\\\angle A = 7^o+33^o\\\angle A = 40^o[/tex]

Charlotte works in a calling center making appointments for a local lawn care service. She earns $40 each full workday plus an additional $2 for each appointment that she schedules. Today, Charlotte needs to earn at least $75
_______Write an inequality to describe this situation. In two or more complete sentences, describe the solution set of this inequality and what it means for Charlotte.
Answer:
40 + 2x ≥ 75
Step-by-step explanation:
X equals 18 or above. This means that in order to meet her goal of $75 dollars, Charlotte needs to schedule at least 18 appointments.
Answer:
A=
2x+40=75
B=
Charlotte would have to schedule 18 appointments.
First you have to subtract 40 from 75 which equals 35
Second you divide 35 by 2 which equals 17.5
Since Charlotte can't schedule 17 1/2 appointments so you round up to 18

R
Points R, T, S, and Q are
collinear
coplanar
both collinear and coplanar
neither collinear nor coplanar
Answer:
Option (4)
Step-by-step explanation:
Coplanar points-
If two or more points are in the same plane, points are called to be coplanar points. Three points in space are always coplanar.
Collinear points-
If two or more points are on a straight line, points are collinear.
Two points are always collinear.
From the diagram attached,
Points R,T,Q and S are neither coplanar nor collinear.
Therefore, Option (4) will be the answer.

Answer:
Answer of 15(i) is the picture . 15(ii) and 17 are solved
Step-by-step explanation:∆ABC where B=90°
→D is mod point of BC so CD=BD
To Prove:
→BC^2=4(AD^2-AB^2)
PROOF:--
In ∆ABD by pythagorus theorem we get,
AD^2=AB^2+BD^2
SO
➡️BD^2= AD^2-AB^2. (1)
NOW ,
BC= BD+CD
BC= 2BD (AS D IS MID POINT)
SQUAREING BOTH SIDES
BC^2= 4BD^2
BY EQUATION 1 WE GOT BD^2 = AD^2-AB^2
Putting this value
➡️BC^2= 4(AD^2-AB^2)
HENCE PROVED
-------------------------------------------------------------------------
17.
Construction : Draw AE ⊥ BC
Proof : In ∆ABE and ∆ACE, we have
AB = AC [given]
AE = AE [common]
and ∠AEB = ∠AEC [90°]
Therefore, by using RH congruent condition
∆ABE ~ ∆ACE
⇒ BE = CE
In right triangle ABE.
AB2 = AE2 + BE2 ...(i)
[Using Pythagoras theorem]
In right triangle ADE,
AD2 = AE2 + DE2
[Using Pythagoras theorem]
Subtracting (ii) from (i), we get
AB2 - AD2 = (AE2 + BE2) - (AE2 + DE2)
AB2 - AD2 = AE2 + BE2 - AE2 - DE2
⇒ AB2 - AD2 = BE2 - DE2
⇒ AB2 - AD2 (BE + DE) (BE - DE)
But BE = CE [Proved above]
⇒ AB2 - AD2 = (CE + DE) (BE - DE)
= CD.BD
⇒ AB2 - AD2 = BD.CD
Hence Proved.

RS = 6y+2, ST=3y +7, and RT=13y-23 What is the value of y? y =________ Find STand RT. ST =_______ RT =_______
Answer:
y = 8, ST = 31 and RT = 81Step-by-step explanation:
Given RS = 6y+2, ST=3y +7, and RT=13y-23, the vector formula is true for the equations given; RS+ST = RT
Om substuting the expression into the formula;
6y+2+3y +7 = 13y - 23
collect the like terms
6y+3y-13y+2+7+23 = 0
-4y+32 = 0
Subtract 32 from both sides
-4y+32-32 = 0-32
-4y = -32
y = -32/-4
y = 8
Since ST = 3y+7. we will substitute y = 8 into the exprrssion to get ST
ST = 3(8)+7
ST = 24+7
ST = 31
Similarly,
RT = 13y-23
RT = 13(8)-23
RT = 104-23
RT = 81
Hence y = 8, ST = 31 and RT = 81

The expression that allows you to calculate the distance between two points is:
d(A; B) = √[(Xb - Xa)² + (Yb - Ya)²]Bringing to our problem:
d(A; B) = √[(9 - 0)² + (14 - 2)²]
d(A; B) = √[9² + 12²]
d(A; B) = √[81 + 144]
d(A; B) = √[225]
d(A; B) = 15PLEASE HELP! I will mark as brainliest if you help me. Solve for x. −ax + 2b > 8
Answer:
x < ( 8 - 2b ) / -a
Step-by-step explanation:
For this problem, we simply will solve the inequality for x.
-ax + 2b > 8
-ax > 8 - 2b
x < ( 8 - 2b ) / -a
Note, the comparison is flipped since a negative multiplicand was used to isolate x.

The segment JL has a definite length of [Drop Down 1]. Segments JK and KL have both definite lengths of [Drop Down 2] and [Drop Down 3], respectively. Both segments are [Drop Down 4]. JL=5x-9, JK=3x and KL=1x+4
Answer:
[tex]JL=56[/tex] [tex]JK=39[/tex] [tex]KL=17[/tex]
Step-by-step explanation:
Your question is not well presented/formatted; however, I can deduce that the question requires that you calculate the following lengths;
JK, KL and JL
Given that
[tex]JL=5x-9[/tex]
[tex]JK=3x[/tex]
[tex]KL=1x+4[/tex]
The relationship between the given parameters is:
[tex]JL = JK + KL[/tex]
Substitute 5x - 9 for JL; 3x for JK and 1x + 4 for KL
[tex]5x - 9 = 3x + 1x + 4[/tex]
Collect Like Terms
[tex]5x - 3x - 1x = 9 + 4[/tex]
[tex]x = 13[/tex]
Now that the value of x has been solved, we can easily get the numeric values of JK, KL and JL by substituting 13 for x
So;
[tex]JL=5x-9[/tex]
[tex]JL=5*13-9[/tex]
[tex]JL=65 - 9[/tex]
[tex]JL=56[/tex]
[tex]JK=3x[/tex]
[tex]JK=3 * 13[/tex]
[tex]JK=39[/tex]
[tex]KL=1x+4[/tex]
[tex]KL=1 * 13+4[/tex]
[tex]KL=13+4[/tex]
[tex]KL=17[/tex]
Hence;
[tex]JL=56[/tex] [tex]JK=39[/tex] [tex]KL=17[/tex]
To estimate the percentage of defects in a recent manufacturing batch, a quality control manager at Toshiba selects every 12th laptop that comes off the assembly line starting with the ninth until she obtains a sample of 110 laptops. What type of sampling is used?
a. Simple random
b. Stratified
c. Convenience
d. Systematic
e. Cluster
Answer:
D) systematic
Step-by-step explanation:
Systematic sampling. With systematic random sampling, one creates a list of every member of the population, and from the list, one can randomly select the first sample element from the first Nth elements on the population list. Thereafter, we select every Nth element on the list. Selection is done according to a random starting point but with a fixed, periodic interval. This interval, which is called the sampling interval, is calculated by dividing the population size by the desired sample size.
