Solve the following system of equations:
y = 5/4x - 2
y = -1/4x + 19
x = ? and y = ?
Answers
Answer:
1. y= 5 /4 x −2
2.x=−4y+76
The value of a and y in the system y = (5/4)x - 2 and y = -(1/4)x + 19 are,
14 and 31/2 respectively.
What are the solutions of a linear system of equations?If a system of equations only contains two linear equations with two variables, the system's equation can be graphed, the graph will have two straight lines, and the intersection point(s) of those lines will be the system's solution.
There are only three matching forms of solution for a given system of equations because there are only three different ways that two straight lines in the plane can graph.
Given,
y = (5/4)x - 2 and y = -(1/4)x + 19.
Multiplying both the equations by 4 we have,
4y = 5x - 8 and 4y = - x + 76.
Subtracting the second equation from the first we have,
0 = 6x - 84.
6x = 84.
x = 14.
Replacing 'x' in any of the equations,
4y = 5(14) - 8.
4y = 70 - 8.
4y = 62.
y = 31/2.

Solve the system of equations by substitution. Write your solution as an ordered pair
4x+8y=20
x=3y-20
Answers
Answer: (-5,5)
Step-by-step explanation:
graphing the two equations on a calculator gets the point (-5,5)
4(3y-20)+8y=20: substitute the second equation into the first equation (hence the name solving by substitution)
12y-80+8y=20: distribute 4 to 3y and 4 to 20
20y-80=20: combine like terms (12y+8y)
20y=100: add 80 to 20
y=5: divide 100 by 20 and you get 5

x - 5 ≥ - 2 represents a line with a close circle on 3 and going towards infinity.
What are inequalities and their types?Inequality is a relation that compares two numbers or other mathematical expressions in an unequal way.
The symbol a < b indicates that a is smaller than b.
When a > b is used, it indicates that a is bigger than b.
a is less than or equal to b when a notation like a ≤ b.
a is bigger or equal value of an is indicated by the notation a ≥ b.
Given, x - 5 ≥ - 2.
x ≥ - 2 + 5.
x ≥ 3.
This represents a line with a close circle on 3 and going towards infinity.

If Angle 3 were not included, the answer would be A, 360°
Step-by-step explanation: When the lines a, b, & c are parallel, the line intersecting them forms angles that are vertical, supplementary and/or corresponding and congruent.
Here, angles 4 and 5 are supplementary. No need to know their exact measurements. Together, their sum is 180°
Angles 1 and 2 are also supplementary, another 180°
But we don't know the measure of angle 3, so getting an exact sum is impossible here.

Answer: x=−2 and y=−5
Step-by-step explanation: 2x−y=1;12x−5y=1
Multiply the first equation by -6,and multiply the second equation by 1.
−6(2x−y=1)
1(12x−5y=1)
Becomes:
−12x+6y=−6
12x−5y=1
Add these equations to eliminate x:
y=−5
Then solvey=−5for y:
y=−5
Now that we've found y let's plug it back in to solve for x.
Write down an original equation:
2x−y=1
Substitute−5foryin2x−y=1:
2x−(−5)=1
2x+5=1(Simplify both sides of the equation)
2x+5+−5=1+−5(Add -5 to both sides)

What is the equation of a line passing through point (2, 3) and has a y-intercept of -5?
Answers
Use y1-y2/x1-x2 to find the slope
Use the points (0,-5) and (2,3)
-5-3/0-2
= -8/-2
= 4
Use y=mx+b where m is the slope and b is the y-intercept
So y=4x-5
