Answer:
Yes, the two expressions are equivalent
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.

Reggie is deciding when to go bowling with his friends. Friday night is glow-bowling night,
with 5 glow-bowling games for $22.50. But the early-bird special on Saturday morning offers
8 games for $30. How much more does glow-bowling cost per game?
Answer:
glow bowling costs $0.75 more per game
Step-by-step explanation:
1. divide $22.50 by 5 games to find the price per game for glow-bowling, which comes out to $4.50
2. divide $30.00 by 8 games to find the price per game for the early-bird special, which comes out to $3.75
3. subtract $3.75 (early-bird bowling) from $4.50 (glow-bowling) and it = $0.75
4.50-3.75=0.75
Answer: The answer is 0.75

m - 7 = -10
Answer:
m=-3
Step-by-step explanation:
m - 7 = -10
Ok so,
in order to get m by itself you just need to do the opposite of -7 which is +7 so you have to add 7 to both sides. On the left, both of the 7's cancel out and on the right -10 + 7 = -3. So, now it should look like this.
m=-3
To check you just need to plug in -3 into the question

Here the question wants to find the range of function. Your answer is incorrect because you are confusing between range and domain.
What is domain?Domain is the set of all x-values. That means any values that are part of x are subset of domain itself. We can find domain two ways which are
Relation methodGraph methodBut we are not talking about domain as we are looking for the range of function.
What is range?Range is the set of all y-values. In the relations or ordered pairs (x, y). Our y is the range. Range can also be called Co-Domain or Output. But of course, we are not talking about finding range using relation method. We are going to find range by looking at the graph.
The range starts from minimum value to maximum value. If there is another point between minimum value and maximum, just ignore it.
Here is a diagram or easier way to understand.
[tex] \boxed{minimum} \Longrightarrow \boxed{maximum}[/tex]
From the graph, our minimum is -5 and our maximum is -1. Notice that there is another opened point at -2 which we are supposed to ignore. Because both minimum and maximum are closed dots. Hence, we use >= or <= only.
Therefore the solution should be
[tex] - 5 \leqslant y \leqslant - 1[/tex]
Answer[tex] - 5 \leqslant y \leqslant - 1[/tex]
......the correct answer is A
For point-slope form, if one of the points is negative then would it become positive. For example, the point I have is (-4,3) and the slope is 1/3, if I'm doing point slope form would the 4 be positive, two negatives equal a positive, right? Then the answer would be y-3=1/3(x+4)
Answer:
yes

Step-by-step explanation:
Frank, = F
Grey = G
Hala = H
Inez = I
3 children sitting in the back seat :
Using combination formula :
4C3
nCr = n! /(n-r)! r!
4C3 = 4! / 1! 3!
4C3 = 4 / 1 = 4
The 4 Possible combinations are :
