The equation 7x + 3x - 18 = 6(x+3) is 9

<h3>What is equation?</h3>

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

given:

7x + 3x - 18 = 6(x+3)

7x + 3x - 18 = 6x+18      [Distributive Property]

10x-18= 6x+18               [Addition Property of Equality]

10x-6x= 18+18               [Combine Like Terms ]

4x=36                            [Subtraction Property of Equality]

4*x=36                            [Multiplication Property of Equality]

x=36/4                           [Division Property of Equality]

x=9

HELP NOW ASAP HURRY i don't got all day!!!!!!!!!!!!!
Anarel [89]

Answer:

15 3/4t^2 + 5 1/4

Explanation:

h(t)=-16t^2+400

We can add 400 then - 64 and show as 8^2

= h(t)=-16t^2+400 - 8^2  

But we also need to change 16t^2;

We divide 64 into 16 = 16/64 =0.25

and show 16t^2 changes by 0.25 = 1/4

15 3/4t^2 + 400-64

Can now look like

15 3/4t^2 + 5 1/4

As 5 1/4 = 64 x 5 1/4 = 336

Which points do the graph of f and g have in g(x)=log2x and g(x)=log10x
Pie

Logarithmic are inverse of exponential functions. The point where graph of f and g intersect is (0, ∞)

<h3>Logarithmic function</h3>

Logarithmic are inverse of exponential functions. Given the following functions;

g(x)=log2x and g(x)=log10x

The point where the graphs intersect is the point where g(x) = g(x)

Equate

log2x = log10x

2x = 10x

The value of x that made them equal is 0

Determine the value of g(x)

g(0) = log2(0)

g(0) = ∞

Hence the point where graph of f and g intersect is (0, ∞)

The equation of the line of best fit of a scatter plot is y = 12x + 7. What is the slope of the equation? −12 −7 12 7
BabaBlast [244]
Well,

Slope-intercept form is given as follows:
y = mx + b

In this equation, "m" is the slope, and "b" is the y-intercept.

y = 12x + 7

We can clearly see that the 12 in the equation is the "m" in the general slope-intercept form.

Therefore, the slope of the equation is 12.
