Answers
Answer:
(3, 2)
Step-by-step explanation:
y = 5x - 13
3x + 5y = 19
~Substitute since we know what "y" equals
3x + 5(5x - 13) = 19
~Simplify
3x + 25x - 65 = 19
28x - 65 = 19
~Solve for x
28x = 84
28x/28 = 84/28
x = 3
~Solve for y using what we got for x
y = 5(3) - 13
y = 15 - 13
y = 2
Best of Luck!
Answer:

28x=84
84/28=3

A game field is 360 feet long. The practice field is 2/5 shorter than the practice field. How long is the game field?feet
Explain your reasoning.
Answers
Answer:
The practice field is 144 feet long.
Step-by-step explanation:
360 x 2/5 = 144
(You would multiply these numbers NOT divide!)
To check my math:
2/5 = 0.4
144/360 = 0.4
By doing the above check, I know the two equations are the same. By seeing this I can know that the answer is correct.

{(y=7x+6),(4x-3y=16):}
Answers
Answer:
(−2, −8)
Step-by-step explanation:
Write the problem as a mathematical expression.
y = 7x + 6
4x − 3y = 16
Replace all occurrences of y in 4x − 3y = 16 with 7x + 6. 4x − 3 (7x + 6) = 16
y = 7x + 6
Simplify 4x − 3 (7x + 6).
−17x − 18 = 16
y = 7x + 6
Solve for x in the first equation.
Move all terms not containing x to the right side of the equation.
−17x = 34
y = 7x + 6
Divide each term by −17 and simplify.
x = −2
y = 7x + 6
Replace all occurrences of x with −2 in each equation.
Replace all occurrences of x in y = 7x + 6 with −2. y = 7 (−2) + 6
x = −2
Simplify 7 (−2) + 6.
y = −8
x = −2
The solution to the system is the complete set of ordered pairs that are valid solutions.

The result can be shown in multiple forms.

Let |r| = 17 at an angle of 40° and |s| = 14 at an angle of 160°. Which expression represents |r + s|?
ty :3
Answers
Answer:
B
Step-by-step explanation:
I got it right on edge2020, 160-40= 120
120/2 = 60 because the angle was gonna be half way between the two angles
The expression that represent | r+s| is Option B
What is a Vector ?A vector is an object that has both magnitude and direction.
It is given that
|r| = 17 at an angle of 40 degree
|s| = 14 at an angle of 160 degree
| r + s| = ?
The magnitude will be determined by the cosine law
and the angle will be 60 degree , obtained from the figure attached with the answer.
[tex]\rm |r + s| = \sqrt{ 17^2 + 14 ^2 -2 * 14 *17 cos 60[/tex]

D. Infinite solutions.
Step-by-step explanation:
Since they give us the equation for (y) we just implement that equation in place of (y) in the second equation
15x+3y=27 now becomes
15x+3(-5x+9)=27
Distribute the 3
15x-15x+27=27
15x and -15x cancel out
27=27
Infinite solutions since both sides are exactly equal.

12y=17-9x and -4y-3x=31 solve by elimination
Answers
Answer:
0 ≠ 110
No solution
Step-by-step explanation:
Solve by Addition/Elimination
12y = 17 − 9x and −4y − 3x = 31
Reorder 17 and −9x. 12y = −9x + 17
−4y − 3x = 31
Add 9x to both sides of the equation.
12y + 9x = 17
−4y − 3x = 31
Reorder the polynomial.
9x + 12y = 17
−4y − 3x = 31
Reorder the polynomial.
9x + 12y = 17
−3x − 4y = 31 9x + 12y = 17
Multiply each equation by the value that makes the coefficients of x opposite.
9x + 12y = 17
(3) ⋅ (−3x − 4y) = (3) (31)
Simplify (3) ⋅ (−3x − 4y).
Apply the distributive property.
9x + 12y = 17
3 (−3x) + 3 (−4y) = (3) (31)
Multiply −3 by 3. 9x + 12y = 17
−9x + 3 (−4y) = (3) (31)
Multiply −4 by 3. 9x + 12y = 17
−9x − 12y = (3) (31)
Multiply 3 by 31. 9x + 12y = 17
−9x − 12y = 93
Add the two equations together to eliminate x from the system.
9x+12y=17
+−9x−12y=93
0=110
Since 0 ≠ 110, there are no solutions. No solution
