Answer:
the slope is 3/2
Step-by-step explanation:
You can substitute it for 5.
2/5 = 0.4 = 40%
5/10 = 0.5 =50%
Answer:
107
Step-by-step explanation:
f(x)=7x^(2)-5
f(4) means that x=4
f(4)=7*4^(2)-5
= 7 * 16 -5
= 112 -5
= 107
Answer:
$58.85
Step-by-step explanation:
Take 7% out of 55 and add it to the total.
The page count will be 10 when the two students will reach the same count.
Step-by-step explanation:
Given,
Typing speed of Annie = 3 pages per hour
Pages already typed by Annie = 4
Let,
x be the number of hours.
y be the total pages typed.
y = 3x+4 Eqn 1
Typing speed of Whitney = 1 page per hour
Pages already types by Whitney = 8
y = 1x+8 Eqn 2
For same number of pages;
Eqn 1 = Eqn 2

Dividing both sides by 2

Putting x=2 in Eqn 1

Putting x=2 in Eqn 2

The page count will be 10 when the two students will reach the same count.
