Answer:

y=14

Step-by-step explanation:

because I solved it and got 14 ......

The value of y in the solution to the system of equations given is 20.

Linear equations are equations which are in the form of ax + by + c = 0, where a, b, and c are real numbers and also coefficients of both the variables, x and y, must not be equal to zero.

There are infinitely many solutions for a linear equation in two variables.

System of linear equations in two variables consist of two or more equations which are linear in two variables.

System of equations given here are,

3y = 18x + 6 and y = 2x + 14

We are solving this by substitution method.

Substituting y = 2x + 14 in 3y = 18x + 6, we have,

3 (2x + 14) = 18x + 6

Applying distributive property on the left hand side of the equation,

(3 × 2x) + (3 × 14) = 18x + 6

6x + 42 = 18x + 6

42 - 6 = 18x - 6x

36 = 12x

x = 3

Substituting x = 3 in y = 2x + 14,

y = (2 × 3) + 14

y = 20

Hence, the value of y in the solution to the system of linear equations 3y=18x+6 and y=2x+14 is 20.

Answer:

[tex] \boxed{ \ - \frac{3}{45} }[/tex]

Step-by-step explanation:

10 3/9 - 10 2/5

we need to convert mixed fractions to improper fractions

[tex]10 \frac{3}{9} = \frac{10 \times 9 + 3}{9} = \frac{93}{9} [/tex]

[tex]10 \frac{2}{5} = \frac{10 \times 5 + 2}{5} = \frac{52}{5} [/tex]

Now, we have 93/9 - 52/5

We need to equate the denominators, before subtracting them.

[tex] \frac{93}{9} - \frac{52}{5} = \frac{93 \times 5}{45} - \frac{52 \times 9}{45} [/tex]

[tex] \frac{465}{45} - \frac{468}{45} [/tex]

[tex] \frac{ - 3}{45} [/tex]

[tex] \boxed{ - \frac{3}{45} }[/tex]

The result of 10 3/9- 10 2/5 is - 3/45

Answer:

x = 3

Step-by-step explanation:

A line with a slope of 0 is a horizontal line parallel to the x- axis with equation

x = c

where c is the value of the x- coordinates the line passes through.

the line passes through (3, - 3 ) with x- coordinate 3 , then

x = 3 ← equation of line

Answer:

f(x) = -3

Step-by-step explanation:

it will be a constant function because if the slope = 0, the y value is not changing

so the equation of the line, f(x) = ax+b, will be f(x) = 0x+b

f(x) = b, b is the y value here

Step-by-step explanation:

convert to fraction form a/b

25 1/3 - 17 5/6

[tex]25 \frac{1}{3} = \frac{25 \times 3 + 1}{3} = \frac{76}{3} [/tex]

[tex]17 \frac{5}{6} = \frac{17 \times 6 + 5}{6} = \frac{107}{6} [/tex]

Now, we have 76/3 - 107/6

[tex] \frac{76}{3} - \frac{107}{6} [/tex]

[tex] \frac{76 \times 2}{6} - \frac{107}{6} [/tex]

Answer:

no solution

Step-by-step explanation:

-2y-3y+8=8-5y-12

-2-3y=-5y

-5y+8=8-5y-12

inverse operation: add 5y to both side

-5y+8=8-5y-12

+5y        +5y

-5y+5y=0, so it cancels out both -5ys

8=8-12

8=-4

there is no value for y to make the equation true, so there is no solution
