Answer:
25%
Step-by-step explanation:
First find the difference in price= $8-$6 = $2
Now, find percentage decrease in the price of sandwich.
Percentage decrease= (difference in price/ original price) *100
= 
*100
=
Percentage decrease=25%
In 8, 9, 10, all the triangles are similar, meaning corresponding sides have the same ratio.
8. hypotenuse / (short side) = 25/x = x/9
x² = 25*9 = 5²×3²
x = √(5²×3²) = 5*3 = 15
9. (long side) / (short side) = x/7 = 9/x
x² = 7*9
x = √(9*7) = 3√7
10. (short side) / (long side) = x/48 = 48/64
x = 48²/64 = 36
Answer:
y=x+20
or
y= 1x + 20
Step-by-step explanation:
The formula for slope is y= mx+ b
m is the slope and b is the y-intercept (where the line touches the y-axis
