The solutions to systems of equations are the variable mappings such that all component equations are satisfied—in other words, the locations at which all of these equations intersect. To solve a system is to find all such common solutions or points of intersection.
A group of equations comprising one or more variables is known as a system of equations. The variable mappings that satisfy each component equation, or the points where all of these equations cross, are the solutions of systems of equations.
Calculating the unknown variables while keeping the equations balanced on both sides is the process of solving a system of equations. Finding the value of the variable that makes the condition of all the provided equations true is how we solve an equation system. There are several ways to solve a system of equations, including

Find the equation of the line that
is parallel to y = 2x + 5 and
contains the point (2, -4).
y = 2x + [?]
Answer:
y=(9,-8)
Step-by-step explanation:
2(2,-4) will give you (4,-8)
therefore y=(4,-8)+5
4+5 which is 9 and nothing will be added to -8
y=(9,-8)
Answer:
y=2x-8

Answer:
(-6.5, 3)
7.2units
Step-by-step explanation:
Given the coordinate
A =(-26, -15)
B = (13, 21)
Midpoint of A and B is expressed as;
X = -26+ 13/2
X = -13/2
X = -6.5
Y = -15+21/2
Y = 6/2
Y = 3
Hence the required midpoint is (-6.5, 3)
b) The distance between the coordinate (-6.5, 3) and (0,0) is expressed as;
D = √(-3)²+(0+6.5)²
D = √9+42.25
D = √51.25
D = 7.2units
Hence the distance between the midpoint and the base camp is 7.2units

Answer:
Value of a in term of x = 8/x
Step-by-step explanation:
Given:
14 = ax + 6
Find:
Value of a in term of x
Computation:
⇒ 14 = ax + 6
Step 1; Subtract 6 from both side
⇒ 14 - 6 = ax + 6 - 6
We get step 2
⇒ 8 = ax
Divide x from both side and we get step 3
⇒ 8 / x = ax / x
Step 4
⇒ 8/x = a
Step 5
⇒ a = 8/x
Value of a in term of x = 8/x
The distance from city a to city b is 1400 miles and from city a to city c is 500 miles. Estimate how many miles farther city b is from city a than city c is
Answer:
900 miles
Step-by-step explanation:
Given that:
Distance from City A to city B = 1400 miles
Distance from City A to City C = 500 miles
Miles farther city B is from city A than city C is ;
Distance from A to B - Distance from A to C
1400 miles - 500 miles
= 900 miles

Answer:
mean: 13
range: 15
there is no mode
median: 13.5
Step-by-step explanation:
mean= 14+9+20+5+17+13 = 78
78÷6= 13
range = highest number minus the smallest number
20-5 = 15
the mode is the number that occurs the most
median= 13+14= 27

if p and q vary inversely and p is 17 when q is 15, determine q when p is equal to 5
Answer:
Step-by-step explanation:
q = 51
Writing these statements symbolically, we get p = k/q. This is inverse variation.
Solving for k, we get k = pq. Thus the governing equation is k = pq, or k = (17)(15) = 255.
We then have a specific equation: p = 255/q, or q = 255/p.
If p is 5, q is q = 255/5 = 51

solve for x.
hint: use your knowledge of parallel lines. what do you know about these angles? are they congruent or supplementary?
Answer:
x = 11
Step-by-step explanation:
The given angles are supplementary which means their sum is 180
8x - 6 + 98 = 180 add like terms
8x + 92 = 180 subtract 92 from both sides
8x = 88 divide both sides by 8
x = 11

to rent a certain meeting room, a college charges a reservation fee of $18 and an additional fee of $6 per hour. The chemistry club wants to spend at most $72 on renting the room. what are the possible numbers of hours the cemetery club could rent the meeting room? use t for the number of hours. write your answer as an inequality solved for t.
Answer:
t ≤ 9 hours
Step-by-step explanation:
Reservation fee = $18
Additional fee per hour = $6
Let x = number of hours
At most in inequality means ≤ less than or equal to
The inequality is
18 + 6t ≤ 72
6t ≤ 72 - 18
6t ≤ 54
t ≤ 54/6
t ≤ 9 hours
