Answer:
1 solution
Step-by-step explanation:
A system of linear equations has no solution when the graphs are parallel.
One x- value of the solution is : -2 or -8
<h3>What is an equation?</h3>
An Equation is an algebraic statement that shows that two quantities are equal.
Analysis:
for one x-value of a solution, f(x) = g(x)
+ 7x -24 = -3x - 40
+7x +3x -24 +40 = 0
+ 10x +16 = 0
+8x +2x +16 = 0
x(x+8) +2(x+8) = 0
(x+2)(x+8) = 0
x = -2 or -8
In conclusion, the values of x are -2 or -8

Step-by-step explanation:
Total initially in bookstore = 45
Sold 13copies, remaining copies = 45-13= 32
Sold 23 copies again, remaining copies = 32-23 = 9
Copies left = 9

Step-by-step explanation:
Answer:
Vertex angle = 124°
Step-by-step explanation:
m<BAC = m<BCA (base angles of isosceles ∆ are congruent)
7x + 1 = 5x + 9
Collect like terms
7x - 5x = -1 + 9
2x = 8
divide both sides by 2
x = 4
Vertex angle = 180 - ((7x + 1) + (5x + 9)) (sum of triangle)
Plug in the value of x
Vertex angle = 180 - ((7*4 + 1) + (5*4 + 9))
Vertex angle = 180 - (29 + 29)
Vertex angle = 124°
