<h3>I'll teach you how to solve 4m^2 - 10= -6</h3>
-----------------------------------------------------
Add 10 to both sides:
4m^2-10+10= -6+10
Simplify:
4m^2= 4
Divide both sides by 4:
4m^2/4= 4/4
Simplify:
m^2= 1
For x^2 = f(a) the solutions are x = 
- :
m= 
, m= -
Simplify:
m = 1, m = -1
Your Answer Is m = 1, m = -1
plz mark me as brainliest :)
A) 3 9/20
b) 4 3/20
c) 3 8/15
d) 6 1/15
e) 8 1/21
f) 8 11/21
g) 18 33/40
h) 21 1/40
22a) Matts' weekly fee is $7.50. We know this is by looking at the Y-axis. If he doesn't sell any books at the beginning of the week, his earnings are at -$7.50. We can assume that he pays that much for internet fee.
22b) Matt makes $1.50 for each book he sells. We know this because if you look at (5,0) and then the next one (6, 1.5), we see that his Y-value has increased by $1.50, which is equal to one book because 6 - 5 = 1 book.
22c) y = 1.5x - 7.5
22d) I'm going to assume that question means $30 in profit. Let's plug in the 30 in the equation. 30 = 1.5x - 7.5. Simplify.
Matt has to sell 25 books to make $30
