Answer:
24 gallons
Step-by-step explanation:
"Mia has filled 3/4 (three quarters) of the fish tank with water. How many gallons has she put in the tank to fill it 3/4 full? Let g be the number of gallons. Then:
(3/4)(32 gallons) = number of gallons Mia put into the tank: 24 gallons
The only solution is (4, -1/2).
The first one is wrong, because of you substitute X and Y or in this case (12, -5/2) into 3x+2y, you get 31=11, Which is an untrue mathmatical statement.
The second one is right, for the same reason. If you substitute X and Y you will get 11=11. which is a true statement.
The third one is wrong, because you have found a true statement.
The fourth one is wrong because you found an untrue statement.
Point-slope form is a different type of way to write a linear equation than slope-intercept (y=mx+b). Point-slope is in this form: y-ypoint=m(x-xpoint)
Point-slope uses a point and the slope (namesake) to make an equation and can be converted to slope-intercept form. For example, if (4, 2) is my point and 2 is my slope, then point-slope form would be y-2=2(x-4). (This can then be solved for y to get slope-intercept)
Remember to use the same point when plugging in for your x and y in the equation, never use two different points.
<h3>
Answer: 69.1 cm</h3>
Work Shown:
C = 2*pi*r
C = 2*3.14*11
C = 69.08
C = 69.1
This is the approximate distance around the circle, aka the perimeter.
Answer:
-8
Step-by-step explanation:
7y+48 = y
-6y = 48
y = -8
