The sum of 3 times a number and 7 is 25

hammer [34]

Mathematically written:

3 * x + 7 = 25

3x + 7 = 25

3x = 25 - 7

3x = 18

x = 18 / 3

x = 6

Proof:

3 * 6 + 7 = 25

18 + 7 = 25

25 = 25 → both sides of the equation are equal, our answer is correct

Notes:

A number - Is an unknown number, called a variable, which in this case is substituted by the letter x.

Hope it helped,

PLEASE HELP ASAP!!! CORRECT ANSWER ONLY PLEASE!!!

Answer: $tan(V)=2.92$

Step-by-step explanation:

For this exercise you need to remember the following Trigonometric Identity:

$tan\alpha =\frac{opposite}{adjacent}$

You must observe the figure given in the exercise.

You can notice that the given triangle UVW is a Right triangle (because it has an angle that measures 90 degrees).

So, you can identify in the figure that:

$\alpha =V\\\\opposite=UW=35\\\\adjacent=VW=12$

Knowing these values, you can substitute them into $tan\alpha =\frac{opposite}{adjacent}$ :

$tan(V)=\frac{35}{12}$

Now you must evaluate:

$tan(V)=2.916$

Finally, rounding to the nearest hundreth, you get:

$tan(V)=2.92$

What are the slope and the y-intercept of the linear function that is represented by the table?

Hunter-Best [27]

Answer:

Slope is -2/5 and y-intercept is -1/3

Step-by-step explanation:

To get the slope, we pick any two points and apply the slope formula

The slope formula is;

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

To get the slope, we select any two points

That will be;

(-3/4, -1/30) and (1/4,-13/30)

Substituting these in the slope formula, we have:

m = (-13/30 + 1/30)/(1/4 + 3/4)

m = 12/30 = -2/5

Generally, the equation of a straight line is;

y = mx + b

m is slope and b is the y-intercept

We already have the slope, to get the y-intercept, we select any of the points

-3/5 = -2/5(2/3) + b

= -3/5 + 4/15 = b

b = (-9 + 4)/15 = -5/15 = -1/3

Slope is -2/5 and y-intercept is -1/3
