Answer:
The slope is 9
The y intercept is (0,7)
Step-by-step explanation:
y=9x+7
The equation is written in slope intercept form
y = mx+b where m is the slope and b is the y intercept
The slope is 9
The y intercept is (0,7)
Answer: the number of tiles will be 49
Step-by-step explanation:
Let x represent the number of tiles that Joshua can buy at either stores.
one store for $0.99 per tile but he he will have to rent a tile saw for $25. Let the total cost of buying x tiles in this store be y. Therefore
y = 0.99x + 25
At another store, he can buy a tile for $1.50 per tile and borrow a tile saw for free. Let the total cost of buying x tiles in this store be z. Therefore
z = 1.5x
To determine the number of tiles for which both costs will be the same, we will equate y to z. It becomes
0.99x + 25 = 1.5x
1.5x - 0.99x = 25
0.51x = 25
x = 25/0.51
x = 49
Answer:
6
Step-by-step explanation:
Using the sine ratio in the right triangle
let x = hypotenuse and sin45° = 
, then
sin45° = 
= 
and
= ( cross- multiply )
× x = 6
Divide both sides by
x = 6
These how many that are left there are 27 pens
