Answer:
1 meter =1,000 millimeters. So, the scale is:
7 mm:1,000 mm Divide both sides by 7
1 mm:142 6/7 mm - This is the scale that Tess used.
Step-by-step explanation:
Answer:

Step-by-step explanation:
a² - b² ← is a difference of squares and factors as
= (a - b)(a + b)
Given
9x² - 16 ← a difference of squares
= (3x)² - 4² → with a = 3x and b = 4
= (3x - 4)(3x + 4)
Answer:
5x+6= 10x-8
14= 5x
x= 2.8
Step-by-step explanation:
Answer:
vertex (5,2)
axis of symmetry: x=5
Step-by-step explanation:
vertex (h,k)
y = a(x - h)² + k
f(x)=(x-5)²+2 a = 1 h = 5 k = 2
vertex (5 , 2)
The axis of symmetry always passes through the vertex of the parabola. The x -coordinate of the vertex is the equation of the axis of symmetry of the parabola.
x = 5
