Answer:
The answer is
[tex]( \frac{1}{2} \: , \: \frac{13}{2} )[/tex]Step-by-step explanation:
The midpoint M of two endpoints of a line segment can be found by using the formula
[tex]M = ( \frac{x1 + x2}{2} , \: \frac{y1 + y2}{2} )[/tex]where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
(3,4) and (-2,9)
The midpoint is
[tex]M = ( \frac{3 - 2}{2} , \: \frac{4 + 9}{2} )[/tex]We have the final answer as
[tex]( \frac{1}{2} \: , \: \frac{13}{2} )[/tex]Hope this helps you
Solve the system: y = 3x + 5 and x = -2y - 4 Answer in this format: (x,y) NO spaces in your answer Enter Answer were BUITIONSWER
Answer:
-2,-1
Step-by-step explanation:
Solve the following system:
{y = 3 x + 5 | (equation 1)
x = -2 y - 4 | (equation 2)
Express the system in standard form:
{-(3 x) + y = 5 | (equation 1)
x + 2 y = -4 | (equation 2)
Add 1/3 × (equation 1) to equation 2:
{-(3 x) + y = 5 | (equation 1)
0 x+(7 y)/3 = -7/3 | (equation 2)
Multiply equation 2 by 3/7:
{-(3 x) + y = 5 | (equation 1)
0 x+y = -1 | (equation 2)
Subtract equation 2 from equation 1:
{-(3 x)+0 y = 6 | (equation 1)
0 x+y = -1 | (equation 2)
Divide equation 1 by -3:
{x+0 y = -2 | (equation 1)
0 x+y = -1 | (equation 2)
Collect results:
Answer: {x = -2 , y = -1

Find the percent of change in the perimeter.
Answer:
-30%
Step-by-step explanation:
currently, the perimeter is: 4 + 6 + 4 + 6 = 20 in.
when the width of 4 in is decreased by 3 in, the new width become (4-3) in = 1 in
therefore, the new perimeter is: 1 + 6 + 1 + 6 = 14 in
the change in perimeter is: 20 in - 14 in = 6 in
now, the percent of change in perimeter will be:
[tex]\frac{change- in -perimeter}{original -perimeter} *100 = \frac{6}{20}*100 = 30[/tex]%
BUT because this change is a DECREASE, you have to put a NEGATIVE sign before the value to inducate that it's a decrease, so
change in perimeter = -30%

Hey can someone explain this please!
Answer:
x = [tex]\frac{7}{2}[/tex]
Step-by-step explanation:
Given
[tex]\frac{5}{4}[/tex] + [tex]\frac{x}{2}[/tex] = 3 ( multiply through by 4 to clear the fractions )
5 + 2x = 12 ( subtract 5 from both sides )
2x = 7 ( divide both sides by 2 )
x = [tex]\frac{7}{2}[/tex]
Amy ran a race in 20.7 seconds. Katie finished the race 0.258 second before Amy. How long did it take Katie to run the race?
Answer: 20.442 seconds
Step-by-step explanation:
From the question, we are informed that Amy ran a race in 20.7 seconds and that Katie finished the race 0.258 second before Amy.
To know how long it took Katie to run the race, we subtract 0.258 seconds from 20.7 seconds. This will be:
= 20.7 - 0.258
= 20.442 seconds

A person of height 1.6m up to the eye level is standing at a point 2m away from the bank of the river and found an angle of elevation of 30°. find the width of the river.
Step-by-step explanation:
tan30° = Height of person / (Distance away from river bank + river's width) = 1/√3.
Therefore 1.6m / (2m + x) = 1/√3
By cross multiplication, 1.6√3 = 2 + x.
Hence, x ≈ 0.77m.
The map below shows the length of a proposed land bridge at Phil Hardberger Park. The length of the land bridge is represented by PH
in the map below.
P(2,55)
H(32, 15)
On the map, each unit represents 1 yard. To the nearest yard, what is the actual length of the land bridge from P to H?
A 50 yards
B. 150 yards
C. 78 yards
D. 234 yards
Answer:
A. 50 yards.Step-by-step explanation:
Given the coordinates of the length of PH as P(2,55) and H(32, 15), to get the actual length of the land bridge from P to H, we will use the formula for calculating the distance between two points.
D = √(x₂-x₁)²+(y₂-y₁)²
PH = √(32-2)²+(15-55)²
PH = √(30)²+(-40)²
PH = √900+1600
PH = √2,500
PH = 50
Hence the actual length of the land bridge from P to H to the nearest yard is 50 yards.
Round 5.05870925358 to 4 decimal places.
Answer:
5.0587
Step-by-step explanation:
First, you have to count to the fourth number after the decimal;
That number is 7, the number after it is the one that will help you round.
Since that number is 0 you round down to 7.
Answer:
5.0587
Step-by-step explanation:
So we look at 5.05870
we count to four after the decimal place and land on the seven, next we look at the digit behind to seven to determine if we can round (remember 5 or more round the score, four or less let it rest).
Find the measures of the labeled angles.
(x+81)° 4x°
(* +81) =
(Type a whole number.)
Answer:
108°
Step-by-step explanation:
The two given angle are vertical angles, which means they are congruent.
(x +81)° = 4x°
81 = 3x . . . . . . . subtract x, divide by °
27 = x . . . . . . . . divide by 3
(27 +81)° = 108° . . . . find the angle measure
The two marked angles have measures of 108°.
Tim is choosing between two cell phone plans that offer the same amount of free minutes. Sprint’s plan charges $39.99 per month with additional minutes costing $0.45. Verizon’s plan costs $44.99 with additional minutes at $0.40. How many additional minutes will it take for the two plans to cost the same?
Answer:
100 minutes
Step-by-step explanation:
Sprints = $39.99 +&0.45
Verizon= $44.99+$0.40
Step 1: Equate the values
[tex]39.99 + 0.45m = 44.99 + 0.40m[/tex]
Step 2 :Collect like terms and simplify
[tex]0.45m - 0.40m = 44.99 - 39.99 \\ 0.05m = 5[/tex]
Step 3 :Divide both sides of the equation by 0.05
[tex] \frac{0.05m}{0.05} = \frac{5}{0.05} [/tex]
Step 4 :Simplify
[tex]m = 100 \\ = 100 \: minutes[/tex]
PLEASE HELP ASAP I NEED THIS DONE ASAP!!!
Answer:
The value of x is 12.
Step-by-step explanation:
Given that perimeter is found when all sides are added together. So we can assume that all side lengths add together will give you 134 imches :
[tex]x + 2x + 5 + 6x - 17 + 3x + 2 = 134[/tex]
[tex]12x - 10 = 134[/tex]
[tex]12x = 134 + 10[/tex]
[tex]12x = 144[/tex]
[tex]x = 144 \div 12[/tex]
[tex]x = 12[/tex]
Answer:
X=12
Step-by-step explanation:
x+2x+5+6x-17+3x+2=134
12x-10=134
12x=144
x=12

Now move the center of rotation, R, to a different position on the coordinate plane.
Next, move the slider bar to rotate pentagon ABCDE. How many times does the
pentagon map back onto itself in this situation? What does this tell you about the
location of the center of rotation?
Answer: If the center of rotation is changed, the pentagon maps back onto itself only one time, when the value of a is 360 degrees that is, when the pentagon completes a full rotation. (just a heads up if your going to copy and paste, change it up a bit because this is word for word :) hope it helped!)
Answer:
If the center of rotation is changed, the pentagon maps back onto itself only one time, when the value of α is 360°—that is, when the pentagon completes a full rotation.

Jake has a can that contains 80% orange
juice and the rest water. The can has 1 liter
of water.
Write an equation using one variable that
can be used to find the total number of
liters of orange juice and water in the can.
How many liters of orange juice are
present in the can?
Answer:
equation 0.8C+1=C
4 liters of orange juice
Step-by-step explanation:
C for can
0.8 as 80%
1 for liters of water
0.8C+1=C
subtract 0.8C
1=0.2C
if 1 liter=20% of a can then 80% is 4 liters

Factorise 6^3+11x^2-12x-5
PLEASE ANSWER URGENT
Answer:
(x - 1)(3x + 1)(2x + 5)
Step-by-step explanation:
Given
6x³ + 11x² - 12x - 5
The sum of the coefficients = 6 + 11 - 12 - 5 = 0
Hence x = 1 is a root and (x - 1) a factor
Dividing 6x³ + 11x² - 12x - 5 by (x - 1) using Synthetic division
1 | 6 11 - 12 - 5
↓ 6 17 5
-------------------------
6 17 5 0 ← remainder
Quotient = 6x² + 17x + 5
Thus
6x³ + 11x² - 12x - 5 =(x - 1)(6x² + 17x + 5) = (x - 1)(3x + 1)(2x + 5)
What is the product of the polynomials below (7x^3+4x)(x^2+2)
Answer:
7[tex]x^{5}[/tex] + 18x³ + 8x
Step-by-step explanation:
Each term in the second factor is multiplied by each term in the first factor, that is
7x³(x² + 2) + 4x(x² + 2) ← distribute both parenthesis
= 7[tex]x^{5}[/tex] + 14x³ + 4x³ + 8x ← collect like terms
= 7[tex]x^{5}[/tex] + 18x³ + 8x
15x+5y=10
5x-7y=12
