what is the equation of a line parallel to the line 2x-3y=6 and that passes through the point (-6,12)

Brrunno [24]

Hello from MrBillDoesMath!

Answer:

y = (2/3)x + 16

Discussion:

Given line:

2x - 3y = 6 => add 3y to both sides

2x = 6 + 3y => subtract 6 from both sides

2x -6 = 3y => divide both sides by 3

y =(2/3)x - 2

The slope of this line, m, (2/3) and any line parallel to the given line has the same slope. We are looking for the line with slope (2/3) passing through (-6, 12)

y = (2/3)x + b => substitute (x,y) = (-6, 12) in the equation

12 = (2/3)(-6) + b => add (2/3)(6) = 12/3 = 4

12 + 4 = (2/3)(-6) + (2/3)(6) + b => as (2/3)(-6) + (2/3)(6) = 0

12 +4 = 0 + b =>

b = 16

Hence the equation of the parallel line through ( -6,12) is

y = mx + b

=(2/3)x + 16

Check: is (-6,12) on this line? Does 12 = (2/3)(-6) + 16 = -4 + 16 = 12? Yes!

Thank you,

MrB

Which of the algebraic expressions are not linear expressions? Select all that apply. a. 3x - 2 b. -9y c. -7x^2^ + 4x d. -1/2x^2

Sedaia [141]

Answer:

c, d and e

Step-by-step explanation:

A linear expression is an expression in which sum of exponents of variables is at most 1 in each of its terms.

Option a: $3x - 2$

Here, the exponent of the variable is 1.

So, it is a linear expression.

Option b: $-9y$

Here, the exponent of the variable is 1.

So, it is a linear expression.

Option c: $-7x^2 + 4x$

Here, the highest exponent of the variable is 2.

So, it is NOT a linear expression.

Option d: $-\frac{1}{2} x^2$

Here, the exponent of the variable is 2.

So, it is NOT a linear expression.

Option e: $8xy$

Here, sum of exponents of variables is 2.

So, it is NOT a linear expression.

Hence, c, d and e are NOT algebraic expressions.

I don't know how to do #86-#88. Any help?

SOVA2 [1]

86 and 87 utilize the Pythagorean theorem. Where those tangent lines meet the circle forms a right angle. So you have a side length of 6 and a hypotenuse of 22. So the missing side length is 21.16. For 87, its the same thing, but you have the 2 legs but are missing the hypotenuse.

3. What is the slope of the line passing through (15,-5) and (3, -8)?

Andrej [43]

M= -8 - -5/ 3 - 15= -8+5/3-15= -3/-12 = 3/12 = 1/4

The slope is 1/4.
The slope formula is m=y2-y1/x2-x1. I plugged in -8=y2, -5=y1, 3=x2, and 15=x1. Then I solved it.
