Answer:

The answer is 4

Step-by-step explanation:

2x + 5 = 13

Now, Subtract 5 from both side we get,

2x + 5 - 5 = 13 - 5

2x = 8

Then, Divide both side by 2 we get,

2x/2 = 8/2

x = 4

Thus, The answer is 4

Answer:

x = 4

Step-by-step explanation:

2x + 5 = 13

We must solve to find the value of 'x'. Take  5 to the right hand side to find x.

2x  = 13 - 5

2x = 8

Take 2 in the '2x' to the right hand side to finally solve and find the value of x.

x = 8 ÷ 2

x = 4

<em>[ Note: when you take a term to the other side of equation, the sign will be the opposite of what it was before. Fore example of 2x was positive on the left hand side of the equation, it will be negative on the right hand. Same goes with multiplications and divisions. If 2x was multiplied with another term on the left hand, it will divided when shifted to the right hand. ]</em>

What the expression (4f-3+2g)-(4g+2)
galben [10]
For this question you can say: 
4f -3 +2g - 4g -2
so now you can simplify and find the answer:
4f -3 -2g -2 = 4f -2g -5
and that's the answer :)))

Question 12(Multiple Choice Worth 1 points)
daser333 [38]

The equation of a line is y=-1/4x-7, (option 1)

<h3>What is the equation of a line? </h3>

A straight line's general equation is y = mx + c, where m denotes the gradient and y = c denotes the point at which the line crosses the y-axis.

<h3>How do you find the equation of a line?</h3>

Write the equation in the form y = mx + b to find the slope m and the y-intercept. This will allow you to graph the equation using the slope and y-intercept.

Given:-

Equation of the line is y=4x+8 

The point through which the line passes (-8,4).

here the slope of the line is m1=4

To find the perpendicular line we know the formula

m1*m2=-1

By putting the value of m1 we get m2= -1/4

By using the one-point formula of the line we have

=>(y-y1)=m2*(x-x1)

By putting the values of y1 and x1 we get

(y1,x1)=(-8,4)

=>(y+8)=-0.25*(x-4)

y+0.25x+7=0

Hence the desired equation of the line is y=-1/4x-7
