Answer:

The equation is already in slope intercept form, -3/2 is the slope and 12 is the y intercept.

Is this a trick question?

Step-by-step explanation:

May I have brainliest please? :)

Answer:

[tex]m=-\frac{2}{3}[/tex]

Step-by-step explanation:

Taking any two points on the line to find the slope

Let us find the slope between the two points we took from the line graph

[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\left(x_1,\:y_1\right)=\left(6,\:-3\right),\:\left(x_2,\:y_2\right)=\left(-6,\:5\right)[/tex]

[tex]m=\frac{5-\left(-3\right)}{-6-6}[/tex]

[tex]m=-\frac{2}{3}[/tex]

Step-by-step explanation:

24*60%= 14.4

Answer:

14.4

Step-by-step explanation

3/5 x 24

3/5 x 24/1

3/5 x 24/1=3x24

                   5 x 1

= 3 x 24

  5 x 1

72

5 x 1

72/5

what you do after that is you divide 72 and 5

72/5 = 14.4

so you answer is 14.4

hope this is right

square root of 770 is 27.748873851

in between would be.... square root of 25= 5

                                        square root of 36= 6

Step-by-step explanation:

2x+4y=8

3x-4y=12

2x+4y+3x-4y=8+12

cancel +4y and -4y

therefore 2x+3x=20

5x=20

x=20/5

x=4

Sibstituting x=4 in 2x+4y=8

2x+4y=8

2*4+4y=8

8+4y=8

4y=8-8

y=0/4

y=0

x=4

y=0

Answer:

180 días.

Step-by-step explanation:

Resolvemos esta pregunta utilizando el método mínimo común múltiple

Buscamos y enumeramos los múltiplos de cada número hasta encontrar el primer múltiplo común.

Este primer múltiplo común es el mínimo común múltiplo.

Múltiplos de 15:

15, 30, 45, 60, 75, 90, 105, 120, 135, 150, 165, 180, 195, 210

Múltiplos de 60:

60, 120, 180, 240, 300

Múltiplos de 90:

90, 180, 270, 360

Por lo tanto,

MCM (15, 60, 90) = 180

Por lo tanto, el número de días que mi pago se concede es de 180 días.

Answer:

B

Step-by-step explanation:

The system of the equation that has only one solution is; 5x-4y=8 and  3x+2y=8.

A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.

We have to determine;

Which system of equations has only one solution

As per the question,  a system of linear equations can have one solution if there is only one point that makes every equation in the system true.  It implies that there is one point that can satisfy all of the equations at the same time.

The system of equations has only one solution is;

5x-4y=8

3x+2y=8

from equation 1

5x-4y=8

5x=8+4y

[tex]x=\frac{8+4y}{5}[/tex]

Putting the value of x in equation 2

3x+2y=8

[tex]3(\frac{8+4y}{5})+2y=8[/tex]

[tex](\frac{24+12y}{5})+2y=8[/tex]

24+12y+10y=[tex]5*8[/tex]

24+22y=40

22y=40-24

22y=16

y=[tex]\frac{16}{22}[/tex]

y=[tex]\frac{8}{11}[/tex]

Putting the value of b in equation 1,

3x+2y=8

3x+2[tex]\frac{8}{11}[/tex]=8

3x=8-[tex]\frac{16}{11}[/tex]

3x=[tex]\frac{88-6}{11}[/tex]

[tex]x=\frac{82}{33}[/tex]

Therefore, the system of equation which has exactly one solution are;

5x-4y=8 and  3x+2y=8.

Answer:

The slope of a line that is perpendicular to the line

y = -1/8x +3​ will be: 8

Step-by-step explanation:

Given the equation

y = -1/8x +3​

comparing the equation with the slope-intercept form

[tex]y=mx+b[/tex]

Here,

so the slope of the line is -1/8.

As we know that the slope of the perpendicular line is basically the negative reciprocal of the slope of the line, so

The slope of the perpendicular line will be:

[tex]\frac{-1}{\frac{-1}{8}}=8[/tex]      ∵ [tex]\mathrm{Apply\:the\:fraction\:rule}:\quad \frac{1}{\frac{b}{c}}=\frac{c}{b}[/tex]

Therefore, the slope of a line that is perpendicular to the line

y = -1/8x +3​ will be: 8

y-intercept: (0, 1)

Line of symmetry calculation: x = -b/2a = -(-2)/2(2) = 0.5

Answer:

No

Step-by-step explanation:

Because 15 is with a different number other then 180, then it isn't linear, or graphable. It won't be a function if you have the same number with different numbers. The input and output won't make sense.

Step-by-step explanation:

Given the expression what Lizzet said was correct

[tex]6^3\times \:\:3^6=18^8[/tex]

No, she is not right. Let me solve the expression

Let us solve the expression

[tex]6^3\times \:\:3^6[/tex]

[tex]=\left(3\times \:2\right)^3\times \:3^6[/tex]

[tex]\mathrm{Apply\:exponent\:rule}:\:\:\:\left(ab\right)^c=a^cb^c[/tex]

[tex]=3^3\times \:2^3\times \:3^6[/tex]          ∵  [tex]\left(3\times \:2\right)^3=3^3\times \:2^3[/tex]

[tex]\mathrm{Apply\:exponent\:rule}:\:\:a^b\times \:\:a^c=a^{b+c}[/tex]

[tex]=2^3\times \:3^{3+6}[/tex]                 ∵  [tex]3^3\times \:3^6=\:3^{3+6}[/tex]

[tex]=2^3\times \:3^9[/tex]

Therefore, the correct expression will be:

[tex]6^3\times \:\:3^6=2^3\times \:\:3^9[/tex]

which can be further simplified such as:

[tex]6^3\times \:\:3^6=2^3\times \:\:3^9[/tex]

             [tex]=8\times \:19683[/tex]

             [tex]=157464[/tex]

Answer:5f+6g+12

Step-by-step explanation:

Just did it and got it right

The value of equivalent expression is,

⇒ 5f + 6g + 12

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

We have to given that;

The expression is,

⇒ 10f - 5f + 8 + 6g + 4

Now, We can simplify as,

⇒ 10f - 5f + 8 + 6g + 4

Combine like terms,

⇒ 5f + 6g + 12

Thus, The equivalent expression is,

⇒ 5f + 6g + 12

Answer:

x = 31.5

Step-by-step explanation:

The triangle on the left has 2 congruent sides and is therefore isosceles.

Thus the 2 base angles are congruent with measure

[tex]\frac{180-54}{2}[/tex] = [tex]\frac{126}{2}[/tex] = 63

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

The triangle on the right is also isosceles with base angles of measure x

63° is an external angle of the triangle on the right, thus

x + x = 63

2x = 63 ( divide both sides by 2 )

x = 31.5
