Answer:
We would multiply the first equation by -3 to eliminate the x-term.
Step-by-step explanation:
Given the system of equations
y = x+2 Equation 1
3x+3y = 6 Equation 2
Multiply the Equation 1 by -3
-3y = -3(x+2) ⇒ -3y = -3x-6 ⇒ -3x+3y = 6
Thus, equation 1 becomes
-3x+3y = 6
Now, adding equation 2
-3x+3y = 6
+
3x+3y = 6
________
0x + 6y = 12
6y = 12
y = 2
Therefore, we would multiply the first equation by -3 to eliminate the x-term.

What is an equation of the line that passes through the points (-6, -3) and
(-3, -5)?
Answer:
y = − 2 /3 x − 7
Step-by-step explanation:
Use the slope formula and slope-intercept form y = m x + b to find the equation.
❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤
Hey buddy ....
I really appreciate God to give me this chance to help u.
Let's see what to do...
-----------------------------------------------------------
First we need to find the slope of the line using this equation :
Suppose a = ( - 6 , - 3 ) , b = ( - 3 , - 5 )
[tex]slope = m = \frac{y(b) - y(a)}{x(b) - x(a)} \\ [/tex]
Just need to put the coordinates in the equation:
[tex]slope = \frac{ - 5 - ( - 3)}{ - 3 - ( - 6)} \\ [/tex]
[tex]slope = \frac{ - 5 + 3}{ - 3 + 6} \\ [/tex]
[tex]slope = \frac{ - 2}{ - 3} \\ [/tex]
[tex]slope = \frac{3}{2} \\ [/tex]
====================================
We have this equation as the point-slope form of the linear functions :
[tex]y - y(one \: \: of \: \: the \: \: given \: \: points) = (slope) \times ( \: x - x(o \: o \: f \: t \: g \: p) \: ) \\ [/tex]
Now just need to put the slope and one the given points ( a or b ) in the above equation:
I like to use a ( you can use b bro )
[tex]y - ( - 3) = \frac{3}{2} \times (x - ( - 6) \: ) \\ [/tex]
[tex]y + 3 = \frac{3}{2} \times (x + 6) \\ [/tex]
[tex]y + 3 = \frac{3}{2} x + 9 \\ [/tex]
Subtract sides 3
[tex]y + 3 - 3 = \frac{3}{2} x + 9 - 3 \\ [/tex]
[tex]y = \frac{3}{2} x + 6 \\ [/tex]
And this is the equation of the line.
So we're done.....

Take care dude ❤❤❤❤❤

Question 24
In A DEF, the bisector of ZF divides the opposite sides into segments that are
4 and 9 in. long. The side of the triangle adjacent to the 4 in segment is 6 in.
long. To the nearest tenth of an inch, how long is the third side of the triangle?
A.13.5
B.27
C.6
D.13
Answer:
1).
Sqrt (7 x 12) = 9.165
2).
Altitude = Sqrt (14 x 8) = 10.583
3).
If FG is the angle bisector of angle F in triangle DEF,
DF/EF = DG/EG
6/EF = 4/9
EF = 13.5 in long.
4).
In triangle QRS, XY is parallel to SR.
SX/XQ = RY/YQ
3/2x = 4.5/7.5
9x = 22.5
x = 2.5
The length of QS
= SX + 2x
= 3 + 5
= 8

Solve for x...............
Answer:
x=26
Step-by-step explanation:
let take the 3rd angle of the triangle y
2x + 76 + y = 180 ( angle sum property)
y = 180 ‐ 76 ‐ 2x
y = 104 ‐ 2x
5x ‐ 2 + y = 180 ( linear pair)
5x‐2+104‐2x = 180 ( y = 104 ‐ 2x)
3x+102=180
3x=180‐102
x=78/3
x=26

In a drawer, a dentist keeps 11 mint, 4 grape, and 5 orange flavored toothpastes, What is the theoretical probability of randomly selecting a grape toothpaste?
Answer:
The probability of randomly selecting a grape toothpaste is 4:20.
Step-by-step explanation:
I hope this helps and I hope u have an Amazing Day!
Answer:
The theoretical probability of selecting a grape toothpaste is 4/20.
Step-by-step explanation:
There are 20 toothpastes in total, you want to find out about the grape. The chances of you picking grape is out of 20, so it's 4/20 since there's only 4 grape.

A sum of money is to be divided among three girls, Anna, Barbara and Chrissy in the ratio 5 : 3 : 2. If Barbara received $400 less than Anna, calculate the amount of money each girl received.
Answer:
Anna received $1000
Barbara received $600
Chrissy received $400
Step-by-step explanation:
Let us solve the problem
∵ The ratio of Anna, Barbara, and Chrissy is 5: 3: 2
∵ Barbara received $400 less than Anna
→ That means Anna - Barbara is 400, find the difference between their ratio
∵ The difference between their ratio = 5 - 3 = 2
→ By using the ratio method
→ Anna : Barbara : difference
→ 5 : 3 : 2
→ A : B : 400
→ By using the cross multiplication
∵ A × 2 = 5 × 400
∴ 2A = 2000
→ Divide both sides by 2
∴ A = 1000
∴ Anna received $1000
∵ B × 2 = 3 × 400
∴ 2B = 1200
→ Divide both sides by 2
∴ B = 600
∴ Barbara received $600
Let us use the ratio between Anna and Chrissy to find the amount of Chrissy
→ Anna : Chrissy
→ 5 : 2
→ 1000 : C
→ By using cross multiplication
∵ 5 × C = 2 × 1000
∴ 5C = 2000
→ Divide both sides by 5
∴ C = 400
∴ Chrissy received $400
