Answer:
- 7 / 4
Step-by-step explanation:
( x1, y1 ) = ( 1, 10 )
Here,
x1 = 1
y1 = 10
( x2, y2 ) = ( 5, 3 )
Here,
x2 = 5
y2 = 3
Formula : -
Slope = ( y2 - y1 ) / ( x2 - x1 )
Slope = ( 3 - 10 ) / ( 5 - 1 )
Slope = - 7 / 4
Proper fraction = - 7 / 4
Answer:
B. The rate of increase is 4%
D. 2100 represents the initial deposit.
Step-by-step explanation:
Look at the equation modeling the savings account.
A = 2100(1.04)
1.04 represent the percent the current account is of the previous one.
That is a 4% increase, which remains the same, so B is one of the correct answers.
2100 was the original deposit, so D is correct as well.
Knowing this, B and D are correct.
Answer:
7.2 liters of water must be added to create a 10% bleach solution.
Step-by-step explanation:
18 liters times 14%, or 18 * 0.14, is 2.52. If we want bleach to be 10% of our solution, we can just multiply this number by 10 because 10% times 10 is 100%!! 2.52 * 10 is 25.2. To find how many liters of water you need to add you just find the difference. To do this you subtract your original from your new solution, so 25.2 - 18 = 7.2 liters of water need to be added.
Use the substitution method
f(4)=4-6
=-2
Answer :-2
the corresponding angles are congruent, the consecutive interior angles are supplementary (=180 degrees), alternate interior angles are congruent and alternate exterior angles are congruent. Hope this helps!
