7 picture frames cost $15 at Harris Teeter. At Food Lion, 9 picture frames cost $17. Which is the better buy?

Answer:

f (-3) = 7

Step-by-step explanation:

f (-3) = 4 (-3) + 5

       = -12 + 5

       = -7

Answer:

x = - 9

Step-by-step explanation:

Given

- (5x - 4) = 49 ← distribute the parenthesis by - 1

- 5x + 4 = 49 ( subtract 4 from both sides )

- 5x = 45 ( divide both sides by - 5 )

x = - 9

Answer:

Richard got $30

Step-by-step explanation:

To find how much money Richard got, use cross multiplication:

[tex]\frac{5}{2}=\frac{75}{x}[/tex]

5x = 150

x = 30

Richard got $30.

Answer:

48

Step-by-step explanation:

by doing LCM

Answer:

4 arrangements

Step-by-step explanation:

The greatest number that both 8 and 12 are divisible by is four. If you were to split them up into four arrangements, each one would have two pink roses (8/4=2) and three white roses (12/4=3) with no leftovers :) so visually it would look like WWWPP WWWPP WWWPP WWWPP

Answer:

Step-by-step explanation:

The only way to compare these is to get them into the same format. Then, we will see which is larger. The way to convert a decimal to a percent is to move the decimal 2 places to the right.

0.3 = 30%

30% > 26%

Answer:

[tex]\frac{3}{4}[/tex]

Step-by-step explanation:

To find the slope, you need to find any 2 points on the line.

In this case, there is a point at (0, 0), and a point at (4, 3).

Formula for slope: [tex]m = \frac{rise}{run}[/tex]

The rise is the change in the y axis from point 1, in this case (0, 0), to point 2, in this case (4, 3). The run is the change in the x axis from point 1 to point 2.

You can subtract the point 1 values from point 2 to get the rise and run:

[tex]m = \frac{3 - 0}{4 - 0} = \frac{3}{4}[/tex]

Answer:

The answer is 2x+48

Step-by-step explanation:

1: Distribute

6(3x+4)-4(2x-6)-8x

18x + 24 - 4(2x-6)-8x

2: Distribute

18x + 24 - 4(2x-6)-8x

18x + 24 - 8x + 24 - 8x

3: Add the numbers

18x + 24 - 8x + 24 - 8x

18x + 48 - 8x - 8x

4: Combine like terms

18x + 48 - 8x - 8x

2x+48

Solution:

2x+48

Answer:

-1 1/5

Answer:

y=0

Step-by-step explanation:

y=2x-6 (add 6 to both sides)

6=2x (divide 2 to both sides)

3=x

-----------------------------------------------------------------------------------------------------------------

y=2(3)-6

y=6-6

y=0

Answer:

vertex = (- 1, - 7 )

Step-by-step explanation:

Given a parabola in standard form, f(x) = ax² + bx + c (a ≠ 0 )

Then the x- coordinate of the vertex is

[tex]x_{vertex}[/tex] = - [tex]\frac{b}{2a}[/tex]

f(x) = - x² - 2x - 8 ← is in standard form

with a = - 1 and b = - 2, then

[tex]x_{vertex}[/tex] = - [tex]\frac{-2}{-2}[/tex] = - 1

Substitute x = - 1 into f(x) for corresponding y- coordinate

f(- 1) = - (- 1)² - 2(- 1) - 8 = - 1 + 2 - 8 = - 7

vertex = (- 1, - 7 )

Answer:

slope= -5/2

slope= -1

slope=1/2

10. slope=-1/3

-5y=7x+20

y=-7/5x-4

11. slope=-7/5

y=-5x+3

12. slope = -5

Answer:

-3x² +6x -1 = 0

Step-by-step explanation:

x2 - 2x + = 4(x2-2x +1)-3

x² - 2x = 4x²-8x +4 - 3

x²-4x²-2x+8x = 4-3

-3x² +6x = 1

-3x² +6x -1 = 0

Answer:

13. r = 7.5cm

14. r = 3.25in

15. r = 1.5 ft

16. r = 4m

Step-by-step explanation:

d/2 = r

Divide the diameter by 2 to get the radius

Answer:

Hey buddy, here is your answer. Hope it helps you .

Step-by-step explanation:

13. Radius= diameter/2

= 15/2

= 7.5cm

14. 6.5/2

= 3.25 in.

15. 3/2

=1.5 ft

16. 8/2

=4 m

This is what I got. I don't see anything in the equation that has "i" in it.

If it is supposed to be (-7-4i)(8-6) foil the problem.

-56+42-32i+24i  combine like terms

the answer is -14-8i
