AURORKA [14]3 years ago
7 0
Answer: r=(-189)

first you subtract both sides by 8 and get -21=r/9

then you multiply 9 with each side and get -189 = r

you can check by rewriting the problem with -189 as r and solving the equation

never [62]

Answer:

x=6.25\\y=-1.25

Step-by-step explanation:

3x+5y=10\\x+3y=1\\\\

Second equation times 3:

3x+9y=3

1st equation minus equation above:

-4y=7\\y=-7/4

Insert to equation:

3x+\frac{-35}{4}=10\\12x-35=40\\12x=75\\x=75/12=6.25

Solve the quadratic equation y^2-2y-35=0
soldier1979 [14.2K]

Hello,

To solve we need to factor y^2-2y-35:

(y-7)(y+5)=0

Now solve for :

(When will (y-7)(y+5)equal zero?)

When y-7=0 or y+5=0

Solve for the 2 equations above and;

y= 7,-5

Hope this helps, have a great day!

The oblique prism below has an isosceles right triangle base. An oblique right triangular prism is shown. The triangular bases h
balandron [24]

The volume of the geometry that is oblique prism is \rm 0.5x^3 + x^2. Then the correct option is A.

<h3>What is Geometry?</h3>

It deals with the size of geometry, region, and density of the different forms both 2D and 3D.

Given

The oblique prism below has an isosceles right triangle base.

The triangular bases have 2 sides with a length of x.

The distance from the 2 triangular bases is (x + 3).

The vertical height of the prism is (x + 2).

The volume of the oblique prism will be

\rm Volume = Area\ of \ triangle * Vertical\ Height \\\\Volume = \dfrac{1}{2} (Base)^2 * Vertical \ Hetght\\\\Volume = \dfrac{1}{2} x^2 (x + 2)\\\\Volume =  \dfrac{1}{2} x^3 + x^{2} \\\\

The volume of the oblique prism is \rm 0.5x^3 + x^2.

Thus, option A is correct.

More about the geometry link is given below.
