Step-by-step explanation:

because i pay attention in math class

The equation y = x has the positive slope.

Slope of a line is the ratio of the change in y coordinates to the change in the x coordinates of two points given.

Slope can also be defined as the tangent of the angle that the line is making with the positive X axis.

Given three equations which are in the form of slope intercept form of the equation of a line.

Slope intercept form of a line is y = mx + d, where m is the value of the slope and d is the value of the y intercept.

y intercept is the y coordinate of the point on the line where it touches the Y axis. The x coordinate will be 0 there.

Equations given are

y = -x + 0 ⇒ Slope = -1

y = x ⇒ Slope = 1

y = -4 ⇒ Slope = 0

So y = x has the slope equal to 1 which is positive.

Hence the equation y = x has the positive slope.

Answer:

Angle O = 72°, Angle M = 18°, Angle N = 90°

Step-by-step explanation:

According to the angle sum theorem, all interior angles of a euclidean triangle always add up to 180°.

given 5(Angle M) = Angle N, and 4(Angle M) = Angle O, you can substitute these equations into the equation defined by this theorem, Angle M + Angle N + Angle O = 180°

. Angle M + 5(Angle M) + 4(Angle M) = 180°

10(Angle M) = 180°.

then you divide. Angle M = 18°

with this statement. you can substitute this into the other equations to get the other answers.

5(18°) = Angle N, 4(18°) = Angle O.

90° = Angle N, 72° = Angle O.

Answer:

1 and 1/3

Step-by-step explanation:

Fx equals 4x-6

Add six to both sides

6 equals 4X

Divide both sides by 4

2/3 equals x

Then GX equals f (2x)

Two times 2/3 is 1 and 1/3

The value of g(x) when f(x) = 4x − 6 and g(x) = f(2x) will be; 1/3

Function is a type of relation, or rule, that maps one input to specific single output.

We have been given that  f(x) = 4x − 6 and g(x) = f(2x), then;

We have to Add six to both sides;

f(x) = 4x − 6

6 = 4X

Now Divide both sides by 4;

2/3 =  x

Then G(X ) is equals to f (2x)

Now, 2( 2/3 ) =  1 /3

The value of g(x) when f(x) = 4x − 6 and g(x) = f(2x) will be; 1/3

Answer:70

Step-by-step explanation:

there should be about 30 people simple math bro. Then for money its 78$

answer: n=7

work:

6n-14=3n+7

6n-14 (+14) = 3n+7 (+14)   add 14 to both sides

6n=3n+21

6n(-3n)=3n(-3n)+21    subtract 3 from both sides

3n=21

3n/3= 21/3    divide by 3 on both sides

n=7

Answer: n = 7

Step-by-step explanation; Simplifying

6n + -7 = 14 + 3n

Reorder the terms:

-7 + 6n = 14 + 3n

Solving

-7 + 6n = 14 + 3n

Solving for variable 'n'.

Move all terms containing n to the left, all other terms to the right.

Add '-3n' to each side of the equation.

-7 + 6n + -3n = 14 + 3n + -3n

Combine like terms: 6n + -3n = 3n

-7 + 3n = 14 + 3n + -3n

Combine like terms: 3n + -3n = 0

-7 + 3n = 14 + 0

-7 + 3n = 14

Add '7' to each side of the equation.

-7 + 7 + 3n = 14 + 7

Combine like terms: -7 + 7 = 0

0 + 3n = 14 + 7

3n = 14 + 7

Combine like terms: 14 + 7 = 21

3n = 21

Divide each side by '3'.

n = 7

Simplifying

n = 7

Answer:

the answer is 103

Step-by-step explanation:62°+15°=77° degrees

Then it is 180° - 77° degrees

180°-77°=103°

The measure of the third angle of a given triangle is 103°.

Given that the measure of two angles is 62° and 15°.

We need to find the measure of the third angle.

The angle sum property of a triangle states that the sum of interior angles of a triangle is 180°.

Let the measure of the third angle be x.

Now,  62°+15°+x=180°

⇒x=180°-77°

⇒x=103°

Therefore, the measure of the third angle is 103°.

Answer:

a. 19/20

B. -5.78

Step-by-step explanation:

Dividing by a fraction is the same as multiplying by its reciprocal. i.e. [tex]\frac{-\frac{2}{3} }{-\frac{8}{9} } =-\frac{2}{3} *-\frac{9}{8} = \frac{3}{4}[/tex] to add to 1/5, change both denominators to 20.

[tex]\frac{3}{4} * \frac{5}{5} = \frac{15}{20}[/tex]

[tex]\frac{1}{5} *\frac{4}{4} =\frac{4}{20}[/tex]

[tex]\frac{15}{20} +\frac{4}{20} = \frac{19}{20}[/tex]

B. Convert all to decimals, then work from the inside out because of the parentheses. -1.6 + 4 = 2.4, 2.4(-0.3) = -0.72, -0.72 - 6.5 =  -5.78
