Answer:
the place value of 4 is 4 × 1000 = 4000 as 4 is at thousand's place. (iv) Here, we also see that the place value of the digit 0 in a number is always zero, whatever may be its position.
Step-by-step explanation:
Answer:
<h2>-8</h2>
Step-by-step explanation:
6y - 8 = c + 6y <em>subtract 6y from both sides</em>
6y - 6y - 8 = c + 6y - 6y
-8 = c
The equation has an infinite many solutions if when we get a true equation with no variable y.
Therefore c = -8
Every one of the answers is correct except 3.4
In the quadratic equation y = ax² + bx + c, the axis of symmetry can be determined with
x = -b/2a
Solution:
Identify the coefficient of the quadratic equation y = 3x² - 6x - 4
a = 3
b = -6
c = -4
The axis symmetry will be
x = -b / 2a
x = -(-6) / 2(3)
x = 6/6
x = 1
The axis of symmetry is x = 1
For the model, every 2 feet would equal 3 inches or every foot would equal 1.5 inches.
You can divide to see how many 2 feet are in 14 feet.
Since there are 7, you can multiply by 3 to see how many inches the model is.
The train model is 21 inches tall.
