Answer:
I would use either a dotted half note for the first measure (equivalent to 3 beats), or use a half note and a quarter note. In the second measure I would use a half note.
Step-by-step explanation:
step 1. properties of equality have an "=" in the equation.
step 2. properties of inequality have a <, <=, >=, or a >.
The length of the line segment using the percentage are as follows:
25% length = 1 cm
50% length = 2cm
100% length = 4 cm
75% length = 3 cm
<h3>How to find length with the percentage?</h3>
The line segment 8 cm is 200% . This means it is double of 100%.
Therefore the length can be calculated using the percentage as follows;
100% length = 8 / 2 = 4 cm
Hence,
75% length = 75 / 100 × 4 = 3 cm
Hence,
25% length = 25 / 100 × 4 = 1 cm
50% length = 50 / 100 × 4 = 2cm

Answer:
y = 2x - 3
Step-by-step explanation:
Take any tow point from the line
(x₁ , y₁) = (1 , -1) & (x₂ , y₂) = (0 , -3)
![= \frac{-3-[-1]}{0-1}\\\\=\frac{-3+1}{-1}\\\\=\frac{-2}{-1}\\\\=2](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7B-3-%5B-1%5D%7D%7B0-1%7D%5C%5C%5C%5C%3D%5Cfrac%7B-3%2B1%7D%7B-1%7D%5C%5C%5C%5C%3D%5Cfrac%7B-2%7D%7B-1%7D%5C%5C%5C%5C%3D2)
m = 2 & (1, -1)
y - y₁ = m(x -x₁)
y - [-1] = 2(x - 1)
y + 1 = 2x - 2
y = 2x - 2 - 1
y = 2x - 3
