Answer:
1st one is 9x-2
2nd is -3x -2
3rd one (put 1 instead of x in the given functions then calculate values and multiple )6
Answer:
B
Step-by-step explanation:
B
the vertex is (-5,-2) which eliminates A and C. D says that the x intercepts are both positive which is obviously incorrect making B the correct answer
.15x = 75
Divide both sides by .15 you get 500 minutes
Answer:
C.) -7x - 5y = -48
Step-by-step explanation:
slope AB = (y2 - y1)/(x2-x1)
= {4-(-1)}/{4-(-3)} = 4+1/4+3 = 5/7
slope of BC = -1 ÷ 5/7 = -1 × 7/5 = -7/5
taking -7x - 5y = -48
-5y = 7x -48
y = 7x/-5 - 48
y = -7/5x -48
Solution:
Let me define pyramid first.A pyramid is a Polyhedron , whose base can be any polygon and it's faces are triangular which meet at a point called vertex.
Volume of Pyramid = 
Side of base which is an equilateral triangle= 4 cm
Area of whole pyramid = 12 square cm
Area of Equilateral triangle having side 4 cm=
cm²
So, Area of three triangle which are faces of pyramid = (12 - 4 √3)cm²
Area of triangle = 
12 - 4 √3= 
Height =
Height=(6-2√3) cm
Volume of pyramid = Area of Equilateral triangle which is it's Base × Height of Pyramid
=4√3 × (6-2√3) cm³
=(24 √3 -24)
= 24 (1.732-1)
=24 × 0.732
=17.568 cm³
