Answer:
x = -23
x = -33
Step-by-step explanation:
-10(x+5) + 9x = -73
-10x - 50 + 9x = -73
x - 50 = - 73
x = -73 + 50
x = -23
-5(x + 8) + 2x = 59
-5x - 40 + 2x = 59
-3x - 40 = 59
-3x = 59 + 40
-3x = 99
x = 99/-3
x = -33
Answer:
(1.36 × 
) - (4 × 
) = 132000kg
1.32 × kg = 1320000
Answer:
5 different triangles
Step-by-step explanation:
we know that
The number of diagonals of an n-sided polygon is given by the formula :
where
n is the number of sides
In this problem
n=5
substitute
see the attached figure to better understand the problem
The number of different triangles that can be formed by the sides of the polygon and its diagonals is equal to 5
so
Triangles
AEB
EDC
BCD
ACD
EBC
see the attached figure
Answer:
16
Step-by-step explanation:
correct on Edg
Find the derivative of the curve to find the line slope at the given point
sqrt(xy) + 4 dy/dx = 39
0.5(xy)^(-0.5) * (y + x dy/dx) + 4dy/dx= 0
No need to amplify simply plug in the given point ( 1,9)
0.5 ( 1 * 9)^(-0.5)* ( 9 + dy/dx) + 4dy/dx = 0
Solve for dy/dx
1/6( 9 + dy/dx) = -4dy/dx
9 + dy/dx = -24 dy/dx
-25dy/dx = 9
dy/dx = -9/25
as your question implies , you know the rest of the steps.
