Step-by-step explanation:
<h3>Factorize : 9x² - y² </h3>
<h3>Applied Formula = a²- b² = (a + b ) (a - b)</h3>
<h3>9x²- 1 y² : </h3>
<h3> = (3x)²– (y)² [ (3x)² = 9x² ]</h3>
<h3> = (3x+y) (3x–y)</h3>

Answer:
1.y= -2x+3 slope -2
2. y= -4/5x-6 slope -4/5
3. y= 1/3x=4 slope 1/3
4. y= x+8 slope 1
5. y= 4x slope 4
6. y= 3/2x+7 slope 3/2
7. y= 3/2x+5 slope 3/2
8. y= -1/5x-3 slope -1/5
Step-by-step explanation:
move variable to the right
change the signs
divide both sides
reorder the terms
Answer:
Step-by-step explanation:
Im pretty sure this 3d object is a prism but the formula for it should be V=B(base area) x h(height) so V= 120 x 10 = 1200in^3
The total number of students is 50
The number of students that named lacrosse as their favorite sport is given as:
From the circle graph, 38% chose lacrosse.
So, the proportion of students that represent lacrosse is:
Substitute 19 for lacrosse
Multiply both sides by 100
Divide both sides by 38
Rewrite as:
Hence, the total number of students is 50
