Can anyone help me on this one? i cant identify the "A, B ,C".
"Given the following linear equations in two variables, identify the values of A,B, and C."
Step-by-step explanation:
The standard form of linear equation:
Ax + By + C = 0Convert each equation into standard form:
#53x = 183x + 0y - 18 = 0A = 3, B = 0, C = - 18#6y/2 = - 50x + 1/2y + 5 = 0A = 0, B = 1/2, C = 5is -2x+3 the same as 2x-3
Answer:
no they are different numbers, however their signs are inverted
Step-by-step explanation:
Answer:
no
Step-by-step explanation:
-2x+3 is not the same as 2x-3 because, let's say we set each equation equal to something...
-2x+3 = 10 2x-3 = 10
-3 -3 +3 +3
------------------ -----------------
-2x = 7 2x = 13
x = [tex]\frac{7}{2}[/tex] x = [tex]\frac{13}{2}[/tex]
x = 3.5 x = 6.5
As we can see, these equations are not the same, because, when we set them equal to the same value, the answers are different.

Average 8, 14, and 11
Answer:
Step-by-step explanation:
you add 8,14, and 11 to get 33 then you divide it by 3, because there are 3 numbers meaning the average is 11.
If that makes, all you have to do is add up all the numbers then divide by the amount of numbers you see to find the average of the numbers.

The base area of a box is 36 square inches. If the volume of the box is 108 cubic inches, what is the height of the box?
The height of a box that has a base area of 36 sq. in. and a volume of 108 cubic inches is: 3 inches.
Recall:
The formula for the volume of a box = base area × height
Given the following dimensions:
base area of box = 36 sq. in.
Volume = 108 cubic inches.
Required: height of the box
Plug in the given values into the formula for the volume of a box
108 = 36 × height
Divide both sides by 36
height = 108/36
height = 3 inches

The ratio of taxis to buses to bikes
is 12:5:18.
How many buses are there if there
are 72 bikes?
Answer:
20 buses
Step-by-step explanation:
Using the given ratio, we can see that for every 12 taxis, there are 5 buses and 18 bikes.
To get from 18 bikes to 72 bikes, we multiply by 4. Therefore, to figure out the number of buses, we multiply it by 4.
5 * 4 = 20

Given the graph below. What is the axis of symmetry (vertex)of the parabola?
Answer:
Answer:
safe speed for the larger radius track u= √2 v
Explanation:
The sum of the forces on either side is the same, the only difference is the radius of curvature and speed.
Also given that r_1= smaller radius
r_2= larger radius curve
r_2= 2r_1..............i
let u be the speed of larger radius curve

In a snail race, the winning snail traveled 5.85 cm in 3/4 of a minute. How fast was the snail traveling per second?
Answer:
0.13 cm per second
Step-by-step explanation:
Lets convert the minutes to seconds:
3/4 minutes = 3/4(60) = 45 seconds
The snail traveled 5.85 cm in 45 seconds
To find out the speed per second, we set up a proportion:
[tex]\frac{5.85}{45} = \frac{x}{1}[/tex] where 45 and 1 represent the number of seconds, and 5.85 and x represent the distance in that set of time
Let's solve for x, or the distance in 1 second:
[tex]\frac{5.85}{45}=\frac{x}{1}\\\\\\\frac{5.85*1}{45x}\\\\\\x = \frac{5.85}{45}\\\\\\\\\\x = 0.13[/tex]
The snail travels 0.13 cm per second.

4) Eric bought a canoe for $333.75. He bought a life vest for $134.87 and an ore paddle for $67.89
The sales tax was 5.25%. What was his total cost?
Answer:
His total cost is $564.68
Step-by-step explanation:
333.75 + 134.87 + 67.89 = 536.51
536.51 x 0.0525 = 28.17
536.51 + 28.17 = 564.68
