Step-by-step explanation:

the gradient = (12-4)/(0+4)=8/4=2

Answer:

gradient = 2

Step-by-step explanation:

Calculate the gradient m using the gradient formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 4, 4) and (x₂, y₂ ) = (0, 12)

m = [tex]\frac{12-4}{0+4}[/tex] = [tex]\frac{8}{4}[/tex] = 2

An expression is defined as a set of numbers, variables, and mathematical operations. The given expression can be written in the form of xⁿ as x⁻⁰°⁶⁶.

In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.

The given expression  [tex]\dfrac{1}{x^{\frac23}}[/tex] can be written in the form of xⁿ using the exponential property 1/x=x⁻¹. Therefore, the expression can be rewritten as,

[tex]\dfrac{1}{x^{\frac23}}\\\\= x^{-\frac23}[/tex]

= x⁻⁰°⁶⁶

Hence, the given expression can be written in the form of xⁿ as x⁻⁰°⁶⁶.

Step-by-step explanation:

You have to use the inverse operation of -6 to get x by itself. So you have to add 6 to each side to get rid of the -6. And -12+6=-6. So, x=6.

Answer:

X is -6

Step-by-step explanation:

You have to add 6 to both sides like -6+6 and -12+6

-12+6=-6 which is the answer because -6-6 is -12

First convert each equation into the standard y = mx + b form by solving:

y = -0.5x + 1

y = 4x - 4

Now look at the graphs to see which represents lines of both equations, in this case it is the last one (D).

Answer:

(x + 4)(5x - 4)

Step-by-step explanation:

[tex]5x^2 + 16x – 16 \\ = 5x^2 + 20x - 4x– 16 \\ = 5x(x + 4) - 4(x + 4) \\ = (x + 4)(5x - 4)[/tex]

Answer:

 (5x - 4) • (x + 4)

Step-by-step explanation:

Multiply the coefficient of the first term by the constant   5 • -16 = -80

Find two factors of  -80  whose sum equals the coefficient of the middle term, which is   16 .

Rewrite the polynomial splitting the middle term using the two factors found in step 2 above,  -4  and  20  

                    5x2 - 4x + 20x - 16

Add up the first 2 terms, pulling out like factors :

                   x • (5x-4)

             Add up the last 2 terms, pulling out common factors :

                   4 • (5x-4)

Add up the four terms of step 4 :

                   (x+4)  •  (5x-4)

            Which is the desired factorization

Answer:

B.   y = 10(2)^x

Step-by-step explanation:

y = ab^x

to find "b" divide the function at x = 3 by the function at x = 2

80 = ab^3

——————

40 = ab^2

This results in

2 = b

to find "a" plug pickany value of x

using x = 2

40 = a(2²)

40 = a(4)

a = 10

With a = 10 and b = 2 the exponential function y = ab^x is

y = 10(2)^x

Answer:

The first one

Step-by-step explanation:

The absolute value of a negative number is the same number but positive if that makes sense. ( ex absolute value of -5 is 5 )

The absolute value of a positive number is literally that number ( ex. absolute value of 6 is 6 )

Thus, the absolute value of 1 is 1 and the absolute value of -99 is 99

99 is greater than 1 which means that the absolute value of -99 is greater than the absolute value of 1

Thus, the answer is the first one

Answer: D trust me it is 100

Step-by-step explanation:

The maximum area the goat can graze is 100Tt ft2​, the correct option is D.

Given

A goat is tethered to a rope that is 10 ft. long.

The area of the circle is equal to the pie times of the square of the radius of the circle.

The maximum area that the goat can graze in the area of the circle that can be formed due to its circular movement.

The length of the rope represents the radius of the circle, so that;

[tex]\rm Area \ the \ goat \ can \ graze =r^2 \times Tt\\\\ Area \ the \ goat \ can \ graze =(10)2 \times Tt\\\\Area \ the \ goat \ can \ graze =100 \ Tt\\[/tex]

Hence, the maximum area the goat can graze is 100Tt ft2​.
