ANYONE get this?? HElp if you can!!Solve each given equation and show your work. Tell whether it has one solution, an infinite number of solutions, or no solutions, and identify each equation as an identity, a contradiction, or neither. a) -2x + 16 + 5x = 9x + 20 - 6x - 4b) 3x – 14 + 4x = 30 + 5xc) 2x + 6 = -x + 10 + 3x – 4

You buy the same number of brushes, rollers, and paint cans. Write an expression in simplest form that represents the total amount of money you spend forpainting supplies... Brush cost $3.99, Paint cost $21.79 and Paint roller cost $6.89

Answers


If you buy ' N ' of each item, then you'll pay  3.99N  for brushes,
21.79N  for cans of paint, and  6.89N  for rollers.

The question assures us that you bought the same number of
each item.  So your total bill at the hardware store checkout is

                      3.99N + 21.79N + 6.89N

                 =  N (3.99 + 21.79 + 6.89)

                 =        32.67 N .
 

Help meh PleAse Which function has the greatest rate of change?

A. 14x – 2y = 8

B. y = 6x – 5

C.
x y
−2 −7
−1 −2
0 3
D.
The Graph is Letter D.

Answers

Rate of Change is the same as Slope.

A.

\sf14x-2y=8

Convert to slope-intercept form.

Subtract 14x to both sides:

\sf-2y=-14x+8

Divide -2 to both sides:

\sf~y=7x-4

So the rate of change here is 7.

B.

\sf~y=6x-5

This is already in slope-intercept form, so the rate of change here is 6.

C.

Take any two points on the graph and plug them into the slope formula.

Let's take (-1, -2) and (0, 3).
               x1  y1        x2 y2

\sf~m=(y_2-y_1)/(x_2-x_1)

Plug in the numbers:

\sf~m=(3-(-2))/(0-(-1))

Subtract:

\sf~m=(5)/(1)

Divide:

\sf~m=5

So the rate of change here is 5.

D.

Take any two points on the line and plug them into the slope formula.

Let's take (0, -2) and (1, 3)
               x1 y1        x2 y2

\sf~m=(y_2-y_1)/(x_2-x_1)

Plug in the numbers:

\sf~m=(3-(-2))/(1-0)

Subtract:

\sf~m=(5)/(1)

Divide:

\sf~m=5

So the rate of change here is 5.

Therefore, A has the greatest rate of change.

Find the slope of the following line:
y=2/3x +4

Answers

y = 2/3*x + 4We knowy = mx+ c, m = gradientTherefore, x = 2/3In these questions, the "coefficient" (or multiplier) of x is equal to the gradient.
Slope-intercept form is

y = mx + b

where,
m is the slope
b is the y-intercept

So for the line:
y = 2/3x + 4

2/3 is the slope
4 is the y-intercept

The slope of y = 2/3x + 4 is 2/3

chris is on a vacation at a lake house for the weekend and decided to rent a canoe for the day. they charge $10 service free plus $38 per hour and he can spend at most $200 how many hours can he rent the canoe

Answers

10 +38h < =200

subtract 10 from each side

38h < =190

divide by 38

h<=5

Answer:  They can rent at most 5 hours

$200 - the $10 fee leaves you  with $190 to spend with $38 per hour

divide 190 by 38 to get 5

you can rent the canoe for 5 hrs
