Answer:
C
Step-by-step explanation:
x + y = 2
Subtract x from both sides;
y = -x + 2
3x - 4y = 27
Substitute y;
3x - 4(-x + 2) = 27
Distribute;
3x + 4x - 8 = 27
7x - 8 = 27
Add 8 to both sides;
7x = 35
Divide both sides by 7;
x = 5

Find the distance between points F(5, 3) and G(2, -7). Round to the nearest hundredth.
Answer:
10.44 units (nearest hundredth)
Step-by-step explanation:
Distance between 2 points
[tex] = \sqrt{(y1 - y2)^{2} + {(x1 - x2)}^{2} } [/tex]
Distance between F and G
[tex] = \sqrt{(3 - ( - 7))^{2} + (5 - 2)^{2} } \\ = \sqrt{ {(3 + 7)}^{2} + {3}^{2} } \\ = \sqrt{ {10}^{2} + 9 } \\ = \sqrt{109} \\ = 10.44 \: units \\ (nearest \: hundredth)[/tex]

Find the distance between (-5,3) and (2,-1).
Answer:
distance = sqrt( 65 ) ~= 8.06
Step-by-step explanation:
To find the distance between two points, we can use the distance formula.
distance = sqrt( [x2 - x1]^2 + [y2 - y1]^2)
distance = sqrt( [-5 - 2]^2 + [3 - -1]^2)
distance = sqrt( [-7]^2 + [4]^2)
distance = sqrt( 49 + 16 )
distance = sqrt( 65 ) ~= 8.06
Cheers.
Answer: d=8.06
Step-by-step explanation:
To this the distance between two points, you would need the distance formula.
Distance Formula: [tex]d=\sqrt{(x_{2}-x_{1} )^2+(y_{2} -y_{1} )^2}[/tex]
Since we have two given points, all we have to do is plug them in.
[tex]d=\sqrt{(2-(-5) )^2+(-1 -3 )^2}[/tex] [parentheses]
[tex]d=\sqrt{(7)^2+(-4 )^2}[/tex] [exponent]
[tex]d=\sqrt{49+16}[/tex] [add]
[tex]d=\sqrt{65}[/tex] [square root]
[tex]d=8.06[/tex]
Now we know that the distance is d=8.06.

the coordinate of point T are (6,12). The midpoint of ST is (3,-8). Find he coordinates of point S. the other endpoint is?
Answer:
(0, -28)
Step-by-step explanation:
Midpoint coordinates are equal to average of the value of endpoint coordinates.
One of End points is T (6,12), the other one is S (x, y) and the midpoint is (2, -8)
So midpoint formula applied to both coordinates:
3 = (6+x)/2 ⇒ 6 = 6+ x ⇒ x = 6 - 6 ⇒ x = 0-8 = (12 + y)/2 ⇒ -16 = 12 + y ⇒ y = -16 - 12 ⇒ y = - 28Point S has coordinates of (0, -28)

is this statement true or false? If AB+BC=AC, then AB=BC
Answer:
true
Step-by-step explanation:
The given statement AB+BC=AC, then AB=BC is false for the line segment.
What is a line segment?A line section that can connect two places is referred to as a segment.
In other words, a line segment is just part of a big line that is straight and going unlimited in both directions.
The line is here! It extends endlessly in both directions and has no beginning or conclusion.
If AC is the line segment and B is in between AC somewhere then the given statement AB+BC=AC, then AB=BC is not necessarily true.
As the two diagrams below;
Diagram 01) →
Here B is the midpoint of AC so AB = BC
Diagram 02) →
Here B is not the midpoint of AC so AB ≠ BC
Hence "The given statement AB+BC=AC, then AB=BC is false for the line segment".

Answer:
43,51, 86
Step-by-step explanation:
The sum of the angles of a triangle are 180
x+ x+8+2x = 180
Combine like terms
4x+8 = 180
Subtract 8 from each side
4x+8-8= 180-8
4x= 172
Divide each side by 4
4x/4 = 172/4
x=43
x+8 = 43+8 = 51
2x = 43*2 = 86
I got you, bro!
Answer:
x = 43
The angle measures of the triangle, in order from least to greatest, are 43, 51, and 86.
Step-by-step explanation:
4x + 8 = 180
Subtract 8 from both sides.
4x = 172
Divide.
x = 43
Find the value of x.
(2x + 4)
(3x + 1)
Answer: x= 17°
Step-by-step explanation:
The interior angle of a triangle adds up to 180 degrees. It indicates that it is a right triangle so it already has a 90 degree angle and if you add it to the two other angles they have to equal 180 degrees.
(2x + 4 ) ( 3x + 1) + 90 = 180
5x + 95 = 180
-95 -95
5x = 85
x = 17

A group of workers took 123.6 hours to
complete a job. A smaller group of workers
will complete the same job, but it will take
them 1.15 times as long as it took the first
group. How long did it take the smaller group
to complete the job?
Answer:
137.814 hours
Step-by-step explanation:
We simply need to multiply the time by the multiplier given in order to find the time it took for the smaller group
123.6 hours is the time and 1.15 is the multiplier
123.6x1.115=137.814 hours

c)Paul Allen developed object-oriented programming.
d)John McCarthy led a team that developed FORTRAN.
Question is based upon our General knowledge in the field of IT and programming languages[tex].[/tex]
Let's see the choices:
1) It is true that Bill Gates founded teh Microsoft, but Guido Von Rossum is the founder of python. So, this is incorrect option.
2) Bjarne Stroustrup is the creater of C++ programming language, and also published the Annotated C++ reference manual. So, this is correct✓.
3) Paul Allen was the one who co-founded the Microsoft cooperation along with Bill Gates. So, this is also incorrect.
4) John McCathy invented or founded LISP, which came after FORTAN, So he isn't the founder of FORTAN. So, this is also Incorrect.
So, correct option is Option B
