The given expression 7y - 15 + 2y and 9y - 15 are equivalent.
What is equivalent expression?
Two algebraic expressions are said to be equivalent if their values obtained by substituting the values of the variables are same, even they look different.
According to the given question.
We have two expressions
[tex]7y - 15 + 2y ...(i)[/tex]
And, [tex]9y - 15 ...(ii)[/tex]
The expression (i) can be written as
[tex]7y - 15 + 2y[/tex]
[tex]=(7y + 2y)-15[/tex] (adding the like terms)
[tex]= 9y -15[/tex]
Hence, the given expression 7y - 15 + 2y and 9y - 15 are equivalent.

change 4x - 5y = 10 into slope intercept form and graph
Answer:
Slope intercept form: y = 4/5x - 2
Step-by-step explanation:
(subtract 4x from both sides) -5y = -4x + 10
(divide everything by -5) y = 4/5x - 2
To graph, place a point at (0,-2), and then travel up 4 and over right 5 (or down 4 and to the left 5) to place the next point, then draw a line through the points

7. 24.25
8. 28.00111604 or 28
Step-by-step explanation:
30 +90 =120 180-120=60
Sin A = a/c, so a = cSin A. Also Cos A = b/c, so b = cCos A so Sin30=14/c=28
Cos30=b/28 b=24.25
now 14^2+24.25^2=c^2 which gives 28.00111604 or 28
