Answer:

Step-by-step explanation:

Add '-5' to each side of the equation.

5 + -5 + Y = -4 + -5 + -4x

Combine like terms: 5 + -5 = 0

0 + Y = -4 + -5 + -4x

Y = -4 + -5 + -4x

Combine like terms: -4 + -5 = -9

Y = -9 + -4x

Simplifying

Y = -9 + -4x

Y=-13x

Answer:

y= -4x-9

Step-by-step explanation:

first you distribute the -4: y+5= -4x-4

then you subtract 5 from both sides to isolate the variable but keep the equation balanced: y= -4x-9

What is the value of x?

Elden [556K]

Answer:

x = 8

Step-by-step explanation:

Since the triangle is right use Pythagoras' identity to solve for x

The square on the hypotenuse is equal to the sum of the squares on the other two sides, thus

x² + 6² = 10²

x² + 36 = 100 ( subtract 36 from both sides )

x² = 64 ( take the square root of both sides )

x = $\sqrt{64}$ = 8

A square fits exactly inside a circle with each of the vertices being on the circumference of the circle. The square has sides l

NNADVOKAT [17]

Answer: The value of x is 5.970.

Step-by-step explanation:

Given: The square has sides length of X cm.

Let r be the radius of the circle.

The square fits exactly inside a circle with each of the vertices being on the circumference of the circle.

Then diagonal of square = diameter of circle

i.e. $\sqrt{2}x= 2r$ [Diagonal of square = $\sqrt{2}$ (side)]

i.e. $r=\dfrac{x}{\sqrt{2}}$

area of circle = $\pi r^2$

i.e. $56=\frac{22}{7}(\frac{x}{\sqrt{2}})^2$

$56=\frac{22}{7}\times\frac{x^2}{2}\\\\\Rightarrow\ x^2= \dfrac{7}{11}\times56\\\\\Rightarrow\ x^2=35.636\\\\\Rightarrow\ x=\sqrt{35.636}\approx5.970$

Hence, the value of x is 5.970.

2(x+16)= 6x please help me :)

jeka94

Let solve:

$2(x+16) = 6x\\2x + 32 = 6x\\32 = 4x\\4x = 32\\x = 8$

Thus <u>x = 8</u>

<u></u>

Hope that helps!
