Find the value of each variable. 3x 2y 34
nikklg [1K]

X= 30

Y=28

Step-by-step explanation:

It's a right-angle triangle. So, 3 x 30 will give you a 90 degree angle.

180-90=90

That means the next 2 angles should add to 90.

2x28=56

56+34=90

Hope this helps!

20y-10x=5 in slope intercept form can you explain the steps
Studentka2010 [4]

Given:

The equation is

20y-10x+5

To find:

The slope intercept form of the given equation.

Solution:

The slope intercept form of a linear equation is

y=mx+b

Where, m is slope and b is the y-intercept.

We have,

20y-10x=5

We need to isolate y. Add 10x on both sides.

20y-10x+10x=5+10x

20y=5+10x

Divide both sides by 20.

\dfrac{20y}{20}=\dfrac{5+10x}{20}

y=\dfrac{5}{20}+\dfrac{10x}{20}

y=\dfrac{1}{4}+\dfrac{x}{2}

y=\dfrac{1}{2}x+\dfrac{1}{4}

Therefore, the slope intercept form of the given equation is y=\dfrac{1}{2}x+\dfrac{1}{4}.

2X to the second power minus 4X equals three in standard form
Elena-2011 [213]

Answer:

2x^2-4x=3

standard form of a quadratic equation =ax^2+bx+y=0

so you would bring the 3 over to the other side making the solution 2x^2-4x-3=0

Describe how to transform the quantity of the fifth root of x to the seventh power, to the third power into an expression with a
MrRa [10]

Fifth root of x  is x^1/5  as an exponential expression. .  This to the 7th power is

x ^(1/5 * 7) which is  x^(7/5).  Bringing this to the third power is  x^ (21/5) which is your answer.
