#1: Solve the linear system below using the elimination method. Type your
answer as an ordered pair in the form (#,#).*
5x + 3y = 1
-5x – 7y = 31
The given linear system is:
[tex]\displaystyle \left \{ {{5x+3y=1} \atop {-5x-7y=31}} \right.[/tex]
Linear systems can be solved using either elimination or substitution. However, the question is asking to solve using elimination, so I will use that method.
When eliminating, you can either eliminate x or y. In this system, x is much easier to eliminate. The x variable in the first equation is 5x, and in the second equation, it is -5x. Since 5 and -5 cancel each other out, you don't need to do anything other than add.
[tex]5x+3y=1\\-5x-7y=31[/tex]
[tex]\displaystyle 3y-7y=1+31\\-4y=32[/tex]
Lastly, you need to leave the variable y alone. The variable is currently -4y or -4 times y. To remove it, you need to do the opposite of it, which is dividing by -4.
Divide both sides by -4:
[tex]\displaystyle\frac{-4y}{-4} =\frac{32}{-4}[/tex]
[tex]\displaystyle y=-8[/tex]
Now that you have the value of y, substitute it into one of the equations to find x. I will be substituting it into the first equation.
[tex]\displaystyle 5x+3y=1 \rightarrow 5x+3(-8)=1[/tex]
Open the parentheses and multiply:
[tex]5x-24=1[/tex]
Move 24 to the other side to leave the variable alone:
[tex]5x-24+24=1+24[/tex]
You will be adding since you're "removing" it by doing the opposite of it.
[tex]5x=25[/tex]
Lastly, divide both sides by 5 to leave x alone.
[tex]\displaystyle \frac{5x}{5} =\frac{25}{5}[/tex]
[tex]x=5[/tex]
[tex]\displaystyle (x,y) \rightarrow (5, -8)[/tex]
The answer is (5, -8).

1.628 > 1.63
I don’t understand math I’m sorry-
Answer:
So that's actually not true. When comparing decimals you should compare each digit. Remember adding a 0 at the end does not change the value of the decimal. So lets look at it up and down:
remember line up the decimal to decimal
1.628
1.630
the first digit is the same. Both of these numbers are also before the decimal.
let's look at the second digit.
1.628
1.630
they are also the same. Both of these are also right after the decimal point.
now let's look at the third digit.
1.628
1.630
In this case, the bottom number has a higher value. Since 3>2, the bottom number is the overall biggest. Or you could look at it and say "Oh! 30 is bigger than 28!" I hope this helps you, and if this wasn't what you were looking for, oops

Is 4 x 2/3 greater than 4?
Answer:
No
Step-by-step explanation:
4 is larger than 1, and 2/3 is less than 1, so if you multiply 4 by anything less than 1 you get a product that is less that the first factor.

GEW has angle measures given by m<=5x+6 m<=3x and m
Answer:
(D) 24°
Step-by-step explanation:
(5x + 6)° + (3x)° + (142 - 4x)° = 180°
5x + 6 + 3x + 142 - 4x = 180
4x + 148 = 180
4x = 32
x° = 8°
m∠E = 3×8° = 24°

f(x) has been

Answer:
f(x) has been translated to the right one and down five.
Step-by-step explanation:
Given
[tex]g(x)=f(x-1)-5[/tex]
Required
Determine the transformation
Taking the analysis one at a time
The relationship between f(x) and f(x - h) is that f(x) is translated h units to the right
So, when f(x) becomes f(x-1), it is as a result of f(x) being translated 1 unit to the right
The relationship between f(x) and f(x) - h is that f(x) is translated h units downwards
So, when f(x - 1) becomes f(x - 1) - 5, it is as a result of f(x - 1) being translated 5 units downwards.
Hence, option 2 answers the question

A family wishes to determine the distance from their home to the nearest park. On a coordinate grid, the house sits at (0, 0), and the park at (16, 11). Using 1 unit = 10 yards, which vector represents the path from the house to the park, and what is the actual distance between them?
components: (16,11), distance: 19.42 yards O components: (16,11), distance: 194 16 yards O components: (120,110), distance: 19.42 yards O components: (160,10), distance: 194.16 yards
Answer:
components: LeftAngleBracket 16, 11 RightAngleBracket distance: 194.16 yards
Step-by-step explanation:
get her done!!! Correct on Edge 2020
The vector represents the path from the house to the park is components: {16,11} and actual distance between them is 194.16 yards. So, option A is correct.
What is the Pythagoras theorem?The Pythagoras theorem states that the square of the longest side must be equal to the sum of the square of the other two sides in a right-angle triangle.
|AC|^2 = |AB|^2 + |BC|^2
In order to find the length of a point to another point that has different y and x points, we will use the pythagorean theorem
(a^2 + b^2 = c^2)
Here, 16 and 11 are the distances from her house,
16^2 + 11^2 = c^2
c^2 = 377
c = 19.416...
Now, we have to convert this to yards;
19.416 x 10 = 194.16 yards
Hence, the vector represents the path from the house to the park is components: {16,11} and actual distance between them is 194.16 yards.
So, option A is correct.

What is true for the equation x=0, x=28, the equation has no solution or the equation has infinitely many solutions
Step-by-step explanation:
Part 1: 4x + 7 = 3(2x - 5)4x+7=3(2x−5)
4x+7=6x-154x+7=6x−15
7=6x-15-4x7=6x−15−4x
7=2x-157=2x−15
7+15=2x7+15=2x
22=2x22=2x
22=2x / 222=2x/2
x=11x=11
Part 2: Sam is not correct because he messed up the second step. He added 2x on both sides to get 7x, instead he should have subtracted.
If n ∥ m, which of the following statements are true? Select all that apply.
Answer:
B. m<3 = 100°
C. m<2 + m<4 = 80°
Step-by-step explanation:
Given that n is parallel to m, the following are the measure of each numbered angles:
m<1 = 60° (vertical angles are congruent)
m<2 = 20° (corresponding angles are congruent)
m<3 = 180 - (m<CAB + m<1) (sum of ∆)
m<3 = 180 - (20° + 60°)
m<3 = 100°
m<4 = 60° (corresponding angles are congruent)
Therefore, the following statements are TRUE:
B. m<3 = 100°
C. m<2 + m<4 = 80°
