Answer:
- there are no solutions (lines do not intersect)
- there is one solution (lines intersect at one point)
- there are an infinite number of solutions (lines overlap—are the same line)
Step-by-step explanation:
"A system of linear equations" covers a lot of territory. In Algebra 1, it usually means two linear equations in two unknowns. Each of those equations will graph as a line on a coordinate plane.
A solution is a point that satisfies all the equations. That is, it is a point that is on all the lines described by the system of equations.
The geometry of lines on a plane comes into play with regard to solutions.
- The lines may be parallel, hence never intersect. (<em>No points</em> will be on all the lines.)
- The lines may intersect at <em>one point</em>.
- The lines may be the same line, overlapping, identical, coincident, consisting of <em>all the same points, an infinite number</em>.
Answer:
Step-by-step explanation:
a = 4
b= 1
c = 2
d =2
Leftside of equation:
No. of H molecules = 4
No. of Cl molecules = 4
No. of O molecules = 4 *4 + 8 =16 + 8 = 24
No. of P molecules = 2
Right side of equation:
No. of H molecules = 4
No. of Cl molecules = 4
No. of O molecules = 2*5 + 2 *7 = 10 + 14 = 24
No. of P molecules = 2
The locations specified in the order regarding the shape will be B. longest side AC; smallest angle ∠C.
<h3>How to express the information?</h3>
From the information given, in the triangle where A = 59°, B is unknown, and C = 41°. Therefore, the value of B will be:
= 180° - (59° + 41°)
= 180° - 100°
= 80°
Therefore, the locations specified in the order regarding the shape will be longest side AC; smallest angle ∠C.
In conclusion, the correct option is B.

Answer:
50 – (3x + 4y + 25)
Step-by-step explanation:
To see how much change she is gonna receive we need to find how much she spent on the items and add them all up:
The calculator was $25
The price of pens and notebooks are unknown so they are represented with x and y respectively.
With given information we can write the following equation to see the change she will receive:
50 – (3x + 4y + 25)
