Answer:

Square root property

Step-by-step explanation:

The given equation is :

[tex]x^2+6=31[/tex]

We need to write the most appropriated technique to solve the above equation.

Subtracting both sides of the above equation by 6 such that,

[tex]x^2+6-6=31-6\\\\x^2=25[/tex]

Now taking square root on both sides we get :

[tex]x=\sqrt{25}[/tex]

The square root property is used here, such that the value of x is :

[tex]x=\pm 5[/tex]

The product of the given numbers is 1.61 × 10⁸.

Scientific notation is a way of writing a large number or small number with many digits in a simpler form using the power of 10.

For example, 30,000 can be written as 3 × 10⁴.

Given that,

We have to multiply the numbers (2.3 x 10¹) (7 x 10⁶).

The numbers in scientific notation uses exponents.

So we have to use the product rule of exponents here.

(2.3 x 10¹) (7 x 10⁶) = (2.3 × 7) × (10¹ x 10⁶)

                              = 16.1 × (10¹ x 10⁶)

We have the product rule, xᵃ . xᵇ = xᵃ⁺ᵇ

So the product is,

(2.3 x 10¹) (7 x 10⁶) = 16.1 × (10¹⁺⁶)

                              = 16.1 × 10⁷

                              = 1.61 × 10⁸

Hence the product in scientific notation is 1.61 × 10⁸.

Step-by-step explanation:

The coefficient for both 5x and 5y is 5; therefore, use the distributive property to rewrite the sum as 5(x + y).

Answer:

Step-by-step explanation:

Answer:

y = 2/3x +4

Step-by-step explanation:

The y intercept is where the line crosses the y axis

y intercept =4

We can find the slope using two points on the line

(0,4) and (3,6)

m = (y2-y1)/(x2-x1)

   = (6-4)/(3-0)

   = 2/3

The equation of a line in slope intercept form is

y = mx+b where m is the slope and b is the y intercept

y = 2/3x +4

Answer:

y = 2/3x +4

Step-by-step explanation:

let the 2 unknown be a and b

X = 0, Y = 4 -> 4 = 0*a+b -> b = 4

Y =0, X = -6  -> 0 = -6*a + 4 -> a = -4/-6 = 2/3

-> y = 2/3x +4

Answer:

Yes, lines CD & AB are perpendicular

Step-by-step explanation:

AB slope: y = -12/8x + 7

CD slope: y = 6/9x - 6

Once the slopes are simplified:

AB: -3/2

CD: 2/3

Answer:AB =10

Step-by-step explanation:

Answer:

Step-by-step explanation:

The linear functions are the ones that can have at most 1 x-intercept. Specifically, slant lines and vertical lines have this characteristic.

The quadratic function doesn't have this characteristic because there are cases where it intercepts x-axis at two points (concave down).

Additionally, the exponential function doesn't have any x-intercept, because its range is restricted.

Therefore, the right asnwer is the linear function

The function that  could have at most 1 x-intercept is y = 2x + 4.

It is the function that can have at most 1 x-intercept. When slant lines and vertical lines should contain the attributes.

The quadratic function doesn't have this attribute since there are cases where it intercepts the x-axis at two points  that represent concave down.

Moreover, the exponential function doesn't have an x-intercept, since its range is restricted.

Therefore, it should be a linear function.
