Find a point-slope form for the line that satisfies the stated conditions. Slope , passing through (-5,4)

I really need this question answered

By:

I don't see a value for the slope. We need that to set the equation, otherwise I can write an unlimited number of equations that pass through (-5,4).

I'll assume a slope so that you can see how the procedure would work. I like 6, so we'll assume a slope of 6.

The equation for a straight line has the form y = mx + b, where m is the slope and y is the y-intercept, the value of y when x = 0. We want a line that has slope 6, so:

y = 6x + b

We need to find b, so substitute the point (-5,4) that we know is on the line:

4 = 6*(-5) + b and solve for b

4 = -30 + b

b = 34

The line is y = 6x + 34

The mass of the part of a metal rod that lies between its left end and a point x meters to the right is 4x2 kg. (See this exampl
Ganezh [65]

Answer:

A) 32 kg/m

B) 48 kg/m

C) 72 kg/m

Step-by-step explanation:

We are given mass is; m = 4x²

Linear density is the derivative of mass with respect to the position x. So linear density is;

ρ = dm/dx

Differentiating 4x²,we have; ρ = 8x

A)at x = 4; ρ = 8(4) = 32 kg/m

B) at x = 6; ρ = 8(6) = 48 kg/m

C) at x = 9; ρ = 8(9) = 72 kg/m

I would round:
1.78 to 2
4.25 to 4
So: 4+2=6

Multiply:<br>(x+y)by (x+y)<br>a+b by a^2-b^2<br>(a+5) by (a^2-2a-3)<br>(a^2-ab+b^3) by (a+b)​
Law Incorporation [45]

Answer:

Multiply:

(x+y)by (x+y)

: \implies(x + y)(x + y)

: \implies \: x(x + y) + y(x + y)

: \implies {x}^{2}  + xy + xy +  {y}^{2}

: \implies{x}^{2}  + 2xy +  {y}^{2}

Multiply:

a+b \:  by  \: a^2-b^2

: \implies( {a}^{2}  +  {b}^{2} ) \times (a + b)

: \implies \:  {a}^{2} (a + b) -  {b}^{2} (a + b)

: \implies \:  {a}^{3}  +  {a}^{2} b -  {ab}^{2} -  {b}^{3}

Multiply:

(a+5) by (a^2-2a-3)

: \implies{(a + 5) \times ( {a}^{2} - 2a - 3) }

: \implies \: a({a}^{2} - 2a - 3) + 5( {a}^{2} - 2a - 3)

: \implies(a \times  {a}^{2}  - a \times 2a - a \times 3) + (5 \times  {a}^{2}  - 5 \times 2a - 5 \times 3)

: \implies{a}^{3} -  {2a}^{2} - 3a + 5 {a}^{2}   - 10a - 15

: \implies{ {a}^{3} +  {3a}^{2}   - 13a - 15}

Multiply:

(a^2-ab+b^3) by (a+b)

: \implies{(a + b) \times ( {a}^{2}  - ab +  {b}^{3} )}

: \implies \: a( {a}^{2} - ab +  {b}^{3}) + b( {a}^{2}  - ab +   {b}^{3}  )

: \implies {a}^{3} -  {a}^{2} b + a {b}^{3}  + {a^2b} -  {ab}^{2}  +  {b}^{4}

: \implies{ {a}^{3}+ab^3 - ab^2+ {b}^{4}  }

Answer:

17 cubes

Step-by-step explanation:

first we do the volume of the rectangular prism to get 135/64.then we do the area of the cube to get 1/8  and now to get how many cubes it fills the prism. 135/64 divide by 1/8 you get 16.8 round off you get 17
