Answer:

Hi, I think y is equal to 42

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

Answer

if x=3 find y

y- x^3+x^2+9

Step-by-step explanation:

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

Answer:

You start with the decimals place since you can't go any further than another whole number.

10.1, 10.2, 10.3, 10.4, 10.5, 10.6, 10.7, 10.8, 10.9 and so on, in the tenths hundredths and thousandths place.

There can be only rational numbers or decimals

Answer:

I think its 256

Step-by-step explanation:

The LCM of 128 and 256 is 256. Steps to find LCM. Find the prime factorization of 128 128 = 2 × 2 × 2 × 2 × 2 × 2 × 2; Find the prime factorization of 256.

Answer:

256

Step-by-step explanation:

1- Find the prime factorization of 128

128 = 2 × 2 × 2 × 2 × 2 × 2 × 2

2- Find the prime factorization of 256

256 = 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2

3- Multiply each factor the greater number of times it occurs in steps i) or ii) above to find the LCM:

LCM = 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2

4- LCM = 256

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:

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{ \sf{7 \frac{1}{2} }}[/tex]

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]
