System of Equations

y=x-5
3x+y=7

Solve?

Answers

$\sf{y=x-5}$
$\sf{3x+y=7}$

Lets solve this by substitution.

Lets plug in y=x-5 into 3x+y=7

So:

$\sf{y=x-5}$
$\sf{3x+y=7}$

Plugging it in:

$\sf{3x+(x-5)=7}$

Solve for x by simplifying that:

$\sf{3x+x-5=7}$

$\sf{4x-5=7}$

Add 5 on both sides

$\sf{4x=12}$

Divide by 4 on both sides

$\sf{x=3}$

Now simply plug x=3 back into any equation and solve for y

So:
$\sf{y=x-5}$

$\sf{y=3-5}$

Simplify that:

$\sf{y=-2}$

So we are left with our final answer which is
$\boxed{\bf{(3,-2)}}$

Y=x-5
-y=3x-7
Add them together
0=4x-12
12=4x
X=3
Y=-2

Hello can anyone help me on the next four math questions please ?1)5(x+2)
2) 4(2x+3)
3) 8(x+2)
4) 5(7x+4) thanks !!!

Answers

5(x + 2)
= 5(x) + 5(2)
= 5x + 10

4(2x + 3)
= 4(2x) + 4(3)
= 8x + 12

8(x + 2)
= 8(x) + 8(2)
= 8x + 16

5(7x + 4)
= 5(7x) + 5(4)
= 35x + 20

$5(x+2)=5x+10\n4(2x+3)=8x+12\n8(x+2)=8x+16\n5(7x+4)=35x+20$

2. If y varies inversely as x and
y = 3 when x = 5, find x when y = 2.5

Answers

Answer:

Step-by-step explanation:

From the law of variation,

y <> 1/x, where <> is the constant of proportionality. Therefore

y = k/x where k is a constant

3 = k/5 and k = 15

To find x when y = 2.5(5/2)

Go back to the second equation

y = k/x

5/2 = 15/x

When you cross multiply

5x = 30.

Divide through by 5,

x = 6.

4. Use the diagram to fill in the blank. Given AB is perpendicular bisector of the CD then AB contains: A) The atc of the circle
B) Then center of the circle
C) The chord of the circle
D) The central angle of the circle

Answers

Line segment AB, which is perpendicular bisector of the chord CD in the circle, contains center of the circle.

What is the property of perpedicular bisector of chord?

Chord is the straight line sement which is made inside the circle by joining two points of that circle.

The bisector of the chord in a circle is always a passes from center of the circle and is a perpendicular line to that chord.

Here, the line segment AB is perpendicular bisector of the CD which is the chord of the circle.
As the perpendicular bisector of the chord in a circle is passes from center of the circle. Thus the line segment AB contains center of the circle.

Hence, line segment AB, which is perpendicular bisector of the chord CD in the circle, contains center of the circle.

F + 1/3 = 5/6 Find f.

Answers

f + 1/3 = 5/6
f = 5/6 - 1/3
f = 1/2

The answer is: f = 1/2 or f = 0.5.

f=1/2
all you have to do is subtract 1/3 from both sides to get 1/2
