The measure of two complementary angles are represented by x+5 and 4x - 15 find the value of x

Answers

Based on the calculations, the value of x will be equal to 20°

First and foremost, we should note that the total angles in a complementary angles equal to 90°.

In this case, we have to add the two angles that we are give and then equate them to 90°. This will be:

(x + 5°) + (4x - 15°) = 90°

x + 5° + 4x - 15° = 90°

Collect like terms

x + 4x = 90° - 5° + 15°

5x = 100°

x = 100°/5

x = 20°

Therefore, based on the calculations, the value of x is 20°

brainly.com/question/17253605

complementry angles sum up to 90.
so, (x+5)+(4x-15)=90
x+4x+5-15=90
5x-10=90
5x=90+10
x=100/5
x=20

What is the positive solution of x2 – 36 = 5x?

Answers

The equation x^2 - 36 = 5x is a quadratic equation and can be solved thus: x^2 - 36 = 5x x^2 - 5x - 36 = 0 x^2 + 4x - 9x - 36 = 0 x(x + 4) - 9(x + 4) = 0 (x - 9)(x + 4) = 0 x - 9 = 0 or x + 4 = 0 x = 9 or x = -4 Therefore, the positive solution of x^2 - 36 = 5x? is 9.

short answer is 9 for anyone who wants it.

Yes the full answer is -4, 9 but the question asks for the POSITIVE SOLUTION so the answer is just 9

What is the slope of any line parallel to the line 2x −3y = 7?

Answers

Slope means which represents the steepness of a line and the slope of any line parallel to the line $2x-3y=7$ is $(2)/(3)$ .

What is the slope of the line?

The slope is used to describe the steepness and direction of lines.

Here the given lines are

$2x-3y=7$

Rearrange the equation into the form $y=mx+c$ where $m$ is the slope and $c$ is the y-intercept.

$y=mx+c\n-3y=-2x+7\n-(-3y)=-(-2x+7)\n3y=2x-7\ny=(2x)/(3)-(7)/(3)$

The slope of the equation is

$m=(2)/(3)$

Hence, the slope of any line parallel to the line $2x-3y=7$ is $(2)/(3)$ .

To know more about slope

#SPJ2

the slope of paralel lines are the same.

therefore to find the slope of a paralel line to 2x −3y = 7, you need to find the slope of this line :)

to do that, we just need to change this into the line equation format, which is y = mx + b (y is the y point, x is the x point, m is the slope, and b is the y intercept)

2x - 3y = 7

7 = 2x - 3y

7+ 3y = 2x

3y = 2x - 7

y = (2/3)x - (7/3)

so the slope is 2/3

any paralel line will have an equation of y = (2/3)x + b

HELP ASAP PLEASE!!!Explain how to tell if a point is a solution for a system of equations.

Answers

Explanation:

When you put the solution values into each equation, the equation becomes a true statement. If all equations become true statements, the point is a solution to the system.

_____

For example, consider the system of equations ...

x + y = 6
x - y = 4

The point (x, y) = (5, 1) is proposed as the solution. When we put those values into the equations, we get ...

5 + 1 = 6 . . . . . true

5 - 1 = 4 . . . . . .true

(x, y) = (5, 1) is the solution to this system of equations. (Since it is a system of two independent linear equations in an equal number of unknowns, we know there is only one solution.)

If the points show below are collinear, what can you conclude about the lengths AB, BC, and AC? SOMEONE PLEASE ANSWWR THIS WILL GIVE BRAINLIEST!!!!

Answers

Answer:

$\sf\nAB+BC=AC$

Explanation:

$\sf\n\textsf{This is because the lengths of line segments AB, BC and AC are the distances}\n\textsf{between the points A,B and C respectively. And since A, B and C are collinear,}\n\textsf{these distances must add up to the total distance between A and C.}$

$\textsf{Here is a simple explanation:}\n\rightarrow \textsf{Suppose you are standing at point A and you want to walk on point C. You }\n\textsf{\ \ \ \ can either walk directly to point C (along line segment AC), or you can}\n\textsf{\ \ \ \ first walk to point B and then from point B to point C (along line segments}\n\textsf{\ \ \ \ AB and BC).}$

$\rightarrow \textsf{The total distance you walk in either case is the same. So, AB+BC=AC.}$
