Answer:

3y=3x+ c

Step-by-step explanation:

-3= x1 and 3 = y1

-6= x2 and 2= y2

y2-y1/ x2-x1 = 2-3/ -6+3 = -1/-3 =1/3 (the gradient)

y =1/3x +c

multiplying both sides by 3

3y= 3x +c in the form of y= mx + c

Answer:

E started with 26 books, sold 13 books, bought 17 more books, and ended with 30 books

Step-by-step explanation:

E has _ books: x

E Sells 1/2 of that _ books: x/2

E buys 17 books and now had 30: (x/2) + 17 = 30

30 - 17 = 13

13 x 2 = 26

x/2 = 26

13 + 17 = 30       <-- checking work

My guess is that x = 13

Step-by-step explanation:

a:

g(10) = -3(10)+1

g(10) = -29

b:

g(x) = 16

-3x + 1 = 16

-3x = 15

x = -5

CHECK:

g(-5) = -3(-5) + 1

g(-5) = 15 + 1

Answer:

Line m is not parallel to Line n.

Line m is perpendicular to Line k

Step-by-step explanation:

1. Calculate slopes of n and m. N = -2 and M = -7/4. The two slopes aren't the same thus they are not parallel

2. Slope of m = -7/4 and k = 4/7. By definition of perpendicular these two fit the description. (to be perpendicular, k = -1/m

Answer:

18x^2 + 66x

Step-by-step explanation:

Apply the distributive property of multiplication:

6x (3x +11) becomes 18x^2 + 66x

The equivalent expressions for given expressions is 18x²+66x.

The given expression is 6x(3x +11).

Equivalent expressions are equivalent expressions  that work the same even though they look different. If two algebraic expressions are equivalent, then the two expressions have the same value when we plug in the same value for the variable.

The equivalent expressions for given expressions can be determined as follows

Using distributive property 6x(3x +11)

= 18x²+66x

Therefore, the equivalent expressions for given expressions is 18x²+66x.

Answer:  See below

y=(4/3)x-5

y = -5x+1

Step-by-step explanation:

The basic form of an equation of a straight line in slope intercept form is y=mx+b, where m is the slope and b the y intercept (the value of y when x=0):

1) slope=4/3, y-intercept=-5 .

y = mx + b:  y=(4/3)x-5

2) slope =-5, y-intercept =1.

y = mx + b:  y = -5x+1
