Answer:
20 2 x 20 =40 per min
Step-by-step explanation:
we know u desperate hehe lol
but
Y= -2x²-3x+2, (form y = ax² +b .x + c
The parabola opens downward & hence it's Vertex is a MAXIMUM.
We know that the axis of symmetry is -b/2a ==>3/(-4) ==>
x= - 3/4 (axis of symmetry. At x=-3/4 , y = 25/8 = 3.125
Hence the axis of symmetry is x= - 3/4 & the vertex is at (-3/4, 25/8)
- 4x^2y * 3xy^3
multiply the numbers : 4*3 = 12
-12x^2xy^3y
apply exponent rule : x^2x = x^2+1 = x^3
-12x^3y^3y
apply exponent rule again : y^3y = y^1+3 = y^4
answer : -12x^3y^4
Answer:
∠7 = 95°
Step-by-step explanation:
∠1 and ∠4 are vertical angles so they are equal.
so:
3x + 10 = 4x - 15
simplify:
x = 25°
∠4 = 4(25) - 15 = 85°
∠8 = ∠4 because they are corresponding angles
∠7 = 180° - 85° = 95° because they are supplementary angles (add together to = 180°)
