A solution to a system of equations are where the two lines cross over each other.
System A the graph shows one line which means the two lines are on top of each other. This means any point on the lines are a solution so there are infinite number of solutions.
System B, the lines cross at one point is there is only one solution which is at (-3,2)
System C the two lines are parallel to each other and never cross so there are no solutions.
Step-by-step explanation:
(i) Infinite solution
If there is only one line then it is a infinite solution.
(ii) One solution
Both are intersecting each other.
Solving
-x - 1 = x + 5
-x - x = 5 + 1
-2x = 6
x = 6/-2
x = -3
y = -x + 5
y = -3 + 5
y = 2
(iii) No solution
Because they are parallel to each other

Find the equation for the line with the given properties. Express the equation in slope-intercept form.
Slope = 7; containing the point (7,-1). What is the equation of the line?
y =
Answers
y - (-1) = 7(x-7)
y+1 =7x -49
y = 7x -49-1
y = 7x -50
Answer:
y = 7x - 50
Step-by-step explanation:
the standard form for a line equation is
y = ax + b
a is the slope.
b is the intercept with the y-axis (x=0).
we know, a = 7
so,
y = 7x + b
to get b we use the point (x = 7, y = -1)
-1 = 7×7 + b = 49 + b
b = -50
=>
y = 7x - 50

A and B are supplementary angles. If A=(3x-17) and B = (2x-23), then find the measure of B
Answers
Answer:
B = 65°
Step-by-step explanation:
Two "supplementary" angles add up to 180 degrees.
Therefore:
A + B = 180
(3x - 17) + (2x - 23) = 180
"Combine like terms" on the left side: the Xs and the numbers.
3x + 2x - 17 - 23 = 180
5x - 40 = 180
Add 40 to both sides:
5x = 220
And divide 5 on both sides:
x = 44
But we're looking for B, which is
(2x - 23) = 2(44) - 23 = 88 - 23 = 65
B = 65°
1. 2x < 10, x = -3

Answer:
I think it is C but it could also be A
Step-by-step explanation:
So here is my explanation. The perfect answer would be {all real numbers p<=345} however because that isn't stated let me explain the answers. A states that there could be 0-345 students however it also states that there could be a fraction of a student (its some wierd thing my Algebra teacher taught me). B states that f(p) is between that but that doesn't make sense. C states all positive intergers less than 345 which means a positive whole number. That means that it is all whole students less than 345 which makes sense however I am iffy cause I think it means there cannot be 345. D states all greater than 0 which exceeds the 345 limit.

Which value of × makes 7+5(x-3)=27+5(x−3)=22, a true statement?
Choose 1 answer:
a=4
b=5
c=6
d=7
Answers
Answer:
Option c = 6Step-by-step explanation:
Given,
7+5(x-3)=27+5(x−3)=22
(Taking one of the equation)
=> 7 + 5(x - 3) = 22
=> 7 + 5x - 15 = 22
=> 5x = 22 + 15 - 7
=> 5x = 30
[tex] = > x = \frac{30}{5} [/tex]
=> x = 6 (Option c)
Answer:
Solve the equation for x:
7 + 5(x - 3) = 225(x - 3) = 15x - 3 = 3x = 3 + 3x = 6Correct choice is c

y - 8= 4/5 ( x-0)
y -8 = 4/5 x
