x² - 4x = 12

x² - 4x - 12 = 0

x² + (2x - 6x) - 12 = 0

x² + 2x - 6x - 12 = 0

x (x + 2) - 6 (x + 2) = 0

(x - 6) (x + 2) = 0

Then the solutions are x = 6 or x = -2.

What is the y-intercept for the graph of this line? 3x - 5y = 6 - 6
photoshop1234 [79]

The right side of the equation is 6-6 which equals 0.

So the equation could be written as 3x-5y = 0

Since the right side of the equation is zero both the x and y intercepts are (0,0)

Value of x? with work
valentinak56 [21]

Given:

The figure of a circle.

Measure of arc = 176°

Measure of angle = (27x+7)°

To find:

The value of x.

Solution:

We know that the measure of central angle is equal to measure corresponding intercepted arc and the measure of central angle is twice of the measure of subtended angle on that arc.

So, the measure of arc is twice of measure of subtended angle on that arc.

m(arc FH)=2\times m\angle FGH

176^\circ=2\times (27x+7)^\circ

\dfrac{176^\circ}{2}=(27x+7)^\circ

88^\circ=(27x+7)^\circ

Now,

88=27x+7

88-7=27x

\dfrac{81}{27}=x

3=x

Therefore, the value of x is 3.

State the domain and range of the following relation<br> x^2+y^2=16
Vlada [557]

The domain and range is  [-4, 4] and [0, 4]

<h3 /><h3>What is Domain and range?</h3>

The domain of a function is the set of values that we are allowed to plug into our function.

The range of a function is the set of values that the function assumes.

x² + y² = 16

y = √16 - x²

For domain under root should not be negative quantity,

16 - x²≥0

16≥x²

So, x≤4 or x≥4

Thus, the domain is  [-4, 4]

Range:

y is maximum at x=0, y=4

y is minimum at x=4, y=0

Thus, range = [0, 4]
