Answer:

There's no solution to this equation, when 2 equations have the same slope but different y-intercepts, they're parallel. This means they never intercept and there is NO solution and we can't solve for x.

Write an expression in factored form to represent the volume in the canister not occupied by the tennis balls.

olya-2409 [2.1K]

Answer:

$\implies V=\pi r^2(h-4 r)$

Step-by-step explanation:

Volume of the canister LESS the volume of 3 tennis balls:

$V=\pi r^2h-3\left(\dfrac43\pi r^3\right)$

Expand brackets:

$\implies V=\pi r^2h-4\pi r^3$

Factor:

$\implies V=\pi r^2(h-4 r)$

A point with an ordinate –1.3 belongs to the graph of the equation x – xy = 46. Find the abscissa of this point.

Neko [114]

Substitute -1.3 for y into equation

x - x(-1.3) = 46
x + 1.3x = 46
2.3x = 46
x = 20 ← abscissa of the point

HELP PLEASE!! Multiply. (2x−7)(x+4) Enter your answer in the box.

Answer:

2 $x^{2}$ +x-28

Step-by-step explanation:

To solve binomial multiplication problems you can use the FOIL method. FOIL means first, outside, inside, last, which tells you what order to multiply the terms.

Multiply the first terms,

(2x-7)(x+4)

2 $x^{2}$

Then the outside terms,

(2x−7)(x+4)

Next the inside terms,

(2x−7)(x+4)

-7x

Finally the last terms,

(2x−7)(x+4)

-28

To find the answer put all of the products together and simplify

2 $x^{2}$ +8x-7x-28

2 $x^{2}$ +x-28
