Swap the sides so that all the terms of the variables are on the left side

x2+3=y

Subtract 3 from both sides

x2=y-3

What is the slope of the line passing through the points (-3,4) and (4,-1)

Serhud [2]

Answer:

slope = - $\frac{5}{7}$

Step-by-step explanation:

Calculate the slope m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (- 3, 4) and (x₂, y₂ ) = (4, - 1)

m = $\frac{-1-4}{4+3}$ = - $\frac{5}{7}$

I need help pls is only 1 question

Yanka [14]

Answer:

$T = 1300$

Step-by-step explanation:

Given

$Radius, r = 9\ in$

$Height, h = 14\ in$

See attachment

Required

Determine the total surface area, T

T is calculated using:

$T = 2\pi r(r + h)$

Substitute values for r and h

$T = 2\pi * 9(9 + 14)$

$T = 2\pi * 9(23)$

Remove bracket

$T = 2\pi * 9*23$

$T = 2\pi * 207$

Take $\pi = 3.14$

So, we have:

$T = 2 * 3.14 * 207$

$T = 1299.96$

$T = 1300$ --- approximated.

Hence, the surface area is 1300 square inch

See this solution/explanation (answer is '7 meters'):

1. According to the condition 'y' means the height, and 'x' - the length from the start of the lift hill.

2. The phrase 'height of 343 meters' means y=343.

3. From the another side y=x³. If to substitute 343 instead of 'y': 343=x³, - it is possible to find the value of 'x'.

x=7 [m] - how far from the start of the lift hill...
