Answer:

D) 5

Step-by-step explanation:

Isolate the variable, y. Note the equal sign, what you do to one side, you do to the other. Divide 2 from all terms within the equation:

(2y)/2 = (10x - 8)/2

y = (10x)/2 - (8)/2

y = 5x - 4

Note the slope-intercept form:

y = mx + b

y = y

x = x

m = slope

b = y-intercept.

In this case, 5 is in place of m, or your slope.

D) 5 is your answer.

Answer:

=5(d)

Step-by-step explanation:

in the equation y=mx+c:m is the gradient

2y=10x-8

divide by 2y on both sides to make y on the other side

y=5x-4

m=slope=gradient

Find the greatest common factor of the monomials.<br><br> 20x², 36x =
Goshia [24]

Answer:

i think its -4

Step-by-step explanation:

Simplifying

-20x2 = 36x

Solving

-20x2 = 36x

Solving for variable 'x'.

Reorder the terms:

-36x + -20x2 = 36x + -36x

Combine like terms: 36x + -36x = 0

-36x + -20x2 = 0

Factor out the Greatest Common Factor (GCF), '-4x'.

-4x(9 + 5x) = 0

-4.

The graph of the function f(x)=3(2)^x -4 passes through the points (0,-1), (1,2), (2,8) and (3,20)

<h3>What are exponential functions?</h3>

When the expression of function is such that it involves the input to be present as exponent (power) of some constant, then such function is called exponential function.

here usual form is specified below. They are written in several such equivalent forms.

The equation of the function is given as:

f(x)=3(2)^x -4

Set x = 0, 1, 2 and 3

f(0)=3(2)^0 -4 = -1\\f(1) = 3(2)^1 - 4 = 2\\f(2) = 3(2)^2- 4 = 8\\\\f(3) = 3(2)^3 - 4 = 20

This means that the graph of the function f(x) = 3(2)^x -4 passes through the points (0,-1), (1,2), (2,8) and (3,20).
