What’s 17=2x+3x+7 so I can no do homework

Mathematics
1 answer:
Nimfa-mama [501]3 years ago
7 0

Answer:

17=2x+3x+7

We move all terms to the left:

17-(2x+3x+7)=0

We add all the numbers together, and all the variables

-(5x+7)+17=0

We get rid of parentheses

-5x-7+17=0

We add all the numbers together, and all the variables

-5x+10=0

We move all terms containing x to the left, all other terms to the right

-5x=-10

x=-10/-5

x=2

2(x-3)=5(x-3)+10<br><br><br> Need urgent help
ArbitrLikvidat [17]

Step-by-step explanation:

2(x-3)=5(x-3)+10

=> 2x - 6 = 5x - 15 + 10

=> -6 + 15 -10 = 5x - 2x

=> 5x -2x = 15 - 6 - 10

=> 3x = 15 - 16

=> 3x = -1

=  > x =  \frac{ - 1}{3} (ans)

Find an equation for the line tangent to the curve at the point defined by the given value of d²y/dx².​
mars1129 [50]

Answer:

Step-by-step explanation:

Given:

x = 2cost,

t = (1/2)arccosx

y = 2sint

dy/dx = dy/dt . dt/dx

dy/dt = 2cost

dt/dx = -1/√(1 - x²)

dy/dx = -2cost/√(1 - x²)

Differentiate again to obtain d²y/dx²

d²y/dx² = 2sint/√(1 - x²) - 2xcost/(1 - x²)^(-3/2)

At t = π/4, we have

(√2)/√(1 - x²) - (√2)x(1 - x²)^(3/2)
