Answer:

y = 500x + 1000

Step-by-step explanation:

The standadrd equation of a line is expressed as y = mx+b

m is the slope

is the y-intercept

Using the coordinate points (0, 1000) and (6, 4000)

Slope = y2-y1/x2-x1

Slope  = 4000 - 1000/6-0

Slope m = 3000/6

Slope m = 500

Since the line cut the y axis at y = 1000, hence the intercept b = 1000

Get the required equation;

Reall that y = mx+b

y = 500x + 1000

X = cos(2t) and y = sin(2t) <br> Find the second derivative
Elodia [21]
Dy/dx = (dy/dt) / (dx/dt)
dy/dt = 2cos(2t)
dx/dt = -2sin(2t)

dy/dx = 2cos(2t)/-2sin(2t) = -cot(2t)

d^y/dx^2 = d(-1/tan(2t))/dx = (tan(2t) * 0 - (-1)*2sec^2(2t))/tan^2(2t) = 2sec^2(2t)/tan^2(2t) = 2csc^2 (2t)

Solve the equation. show all work.<br><br> 3x - 10 = 5x + 22
inysia [295]
<span>Simplifying 3x + 10 = 5x + 22 Reorder the terms: 10 + 3x = 5x + 22 Reorder the terms: 10 + 3x = 22 + 5x Solving 10 + 3x = 22 + 5x Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-5x' to each side of the equation. 10 + 3x + -5x = 22 + 5x + -5x Combine like terms: 3x + -5x = -2x 10 + -2x = 22 + 5x + -5x Combine like terms: 5x + -5x = 0 10 + -2x = 22 + 0 10 + -2x = 22 Add '-10' to each side of the equation. 10 + -10 + -2x = 22 + -10 Combine like terms: 10 + -10 = 0 0 + -2x = 22 + -10 -2x = 22 + -10 Combine like terms: 22 + -10 = 12 -2x = 12 Divide each side by '-2'. x = -6 Simplifying x = -6</span>

at the mall, myla bought a shirt for $25.36, a hat for $5.09 and a belt for $11.45. how much did she spend altogether?
malfutka [58]

The summation of the money Myla spend altogether is $41.9

As in the given problem  we can see Myla bought

a shirt for $25.36 and

a hat for  $5.09  and

a belt for $11.45.

Hence we need to know the cummulative price she spend altogether.

To get the total price we should add the price of shirt hat and belt.

Summing all the prices we get

$25.36+$5.09+$11.45=$41.9

As all the quantities are given in one currency thus we can add them by simple addition formula.

Thus she spend $41.9 altogether at the mall.

Solve for x.<br><br> 7x+15=2x+19<br><br> A)x=9/34<br> B)x=4/9<br> C)x=4/5<br> D)x=20
Rufina [12.5K]
<span>7x+15=2x+19
Subtract 2x from both sides
5x+15=19
Subtract 15 from both sides
5x=4
Divide 5 on both sides
Final Answer: C.) x= 4/5</span>
