Both problems are similar, so we can work the general case first.

For ax +by = c, you can solve for y to put the equation into slope-intercept form.
  by = -ax +c . . . . . . subtract the x-term
  y = (-a/b)x +c/b . .. divide by the coefficient of x

The slope is the x-coefficient, -a/b; the y-intercept is c/b. The function is an odd-degree polynomial function, so its domain and range are both "all real numbers."

2x+3y=18
Slope-intercept form: y = (-2/3)x +6
Domain: all real numbers
Range: all real numbers
Slope: -2/3
Y-intercept: 6

3x-4y > 16
Slope-intercept form: y < (3/4)x -4
Domain: all real numbers
Range: all real numbers
Slope: 3/4
Y-intercept: -4

_____
You will note that the inequality symbol in y < (3/4)x -4 is reversed from that in 3x -4y > 16. That is because in solving for y, we divided by -4. When you multiply or divide an inequality by a negative number, you must reverse the sense of the inequality.

If one diagonal of a rhombus is 15 meters long and it’s area is 157.5 square meters, find the measures of the other diagonal
ycow [4]

Answer:

The other diagonal measures 21m

Step-by-step explanation:

In this question, we are tasked with calculating the length of the second diagonal of as Rhombus given the measure of the surface area of the rhombus and the length of the other diagonal

Mathematically, for a rhombus having two diagonals d_{1} and d_{2} , the area of the rhombus can be calculated mathematically using the formula below;

A = 1/2 ×d_{1} × d_{2}

From the question, we can identify that A = 157.5m^{2} and d_{1} = 15m

we input these in the formula;

157.5 = 1/2 × 15 × d_{2}

315 = 15 d_{2}

d_{2} = 315/15

d_{2} = 21m

Answer:

11

Step-by-step explanation:

LN = LM + MN

=> 22 = 3z + 1 + 3z + 1

20 = 6z

z =  10/3

LM = (10/3)*3+1 = 11

What is an equation of the line that passes through the point (2,−6) and is parallel to the line x−2y=8?
lorasvet [3.4K]

Answer:

y = x/2 - 7

Step-by-step explanation:

First, we need to find the slope of the given equation: x - 2y = 8

Subtract x from both sides

x - 2y = 8

- x        - x

-2y = 8 - x

Divide both sides by -2

-2y/-2 = (8 - x)/-2

y = -4 + x/2

The slope of this equation is 1/2

So the equation of our parallel equation is y = x/2 + b

We have to find b, so plug in the given coordinates

-6 = 2/2 + b

-6 = 1 + b

Subtract 1 from both sides

-6 = 1 + b

- 1    - 1

b = -7

Plug it back into the original equation

y = x/2 - 7
