To rewrite the expression ab+a+b+1, Jozelle first writes (ab+a) + (b+1). What property justifies this?

Answer:

11 cars/day

Step-by-step explanation:

What we know:

After two days, Car-Mart has 43 cars left. After 3 days, it is 32. After five, 10 cars.

Saying that, subtract 32 from 43 to get your rate of 11 cars sold a day.

I can further deduce they started with 76 cars. On day 1 they had 65 cars. On day 4 they had 21 cars. They will have sold all of their cars after day 6.

Answer

x = 2 or x = -2

Option A

Step-by-step explanation:

By shifting it down(we are going 8 units below the origin on the y-axis), we have the equation as;

y = 2x^2 - 8

To find the root, we equate zero

0 = 2x^2 - 8

2x^2 = 8

x^2 = 8/2

x^2 = 4

x = square root of 4

x = +2 or -2

Answer: is A x=y=-2 and x=2

➩ [tex]x=2,-\frac{2}{3}[/tex]

Step-by-step explanation:

[tex]\sqrt{4x^2}=x+2[/tex]

➨ We can also solve by completing both squares, however. Since we can pull out the square root.

[tex]\sqrt{4x^2}=|2x|[/tex] ➩ Define of Absolute Value/Square Root

➩ [tex]\sqrt{x^2}=|x|[/tex]

Thus, our new equation is ➩ [tex]|2x|=x+2[/tex]

To solve an absolute-value equation, let there be two conditions.

➨ Where x ≥ 0

[tex]2x=x+2\\[/tex]

Move x to another side

[tex]2x-x=2\\x=2[/tex]

➨ Where x < 0

[tex]-2x=x+2\\-2x-x=2\\-3x=2\\x=\frac{2}{-3}\\x=-\frac{2}{3}[/tex]

Answer:

x=7 y=6

Step-by-step explanation:

x =  7      hous worked by Lillian

y  = 6      hours worked by Jacob

Step-by-step explanation:

Let call  " x  "  and  "  y  "  numbers of hours Lillian and Jacob worked respectively, then according to problem statement we have:

They both combined a total of 13 hours, therefore

x  +  y  =  13    ⇒   y  = 13  -  x

And the number of ironed shirts was  295  then we have

25*x  +  20*y  =  295

We need to solve that system of equations for   x     and    y   then

25*x   +  20 * ( 13 - x ) = 295

25*x   +  260  -  20*x   =  295

5*x  =  295  -  260

5*x  =  35

x  = 35/5

x  =  7

And  y  =  13  -  x    ⇒   y  =  13 - 7

y  =  6

Answer:

05 units up and down

Step-by-step explanation:

hope this hepled luv!

The phrase that best describes the translation from the graph y = 2x^2 to the graph of y = 2x^2 + 5 is "5 units up".

Let the functions f(x) and g(x) be two real functions.

And g (x) = f (x) + k, where k is real numbers.

The function can be sketched by shifting f (x), k units vertically.

The direction of shift can be found by the value of k:

if k > 0, the base graph shifts k units up, and

if k < 0, the base graph shifts k units down.

Adding a constant term to a function vertically shifts its graph up or down, depending on the sign of the constant.

In this case, the constant term is positive (+5), which means that the graph of y = 2x² + 5 is shifted upward by 5 units compared to the graph of y = 2x².

Therefore, the correct phrase is "5 units up".

Step-by-step explanation:

All of the triangles are similar, so the ratio of short side to long side is the same for all.

  4/8 = k/4

  k = 16/8 = 2 . . . . multiply by 4 and simplify

The value of k is 2.

Solve perimeter of both rectangles and add

Answer:

238 meters

Step-by-step explanation:

Perimeter? The equation is P = 2 ( l * w )

So lets cut this irregular shape into 2 rectangles.

I added a picture to show you.

So on rectangle is 7 by 11 and the other is 7 by 6.

So lets find the perimeter of the larger rectangle first.

P = 2 ( 11 * 7 )

P = 2 ( 77 )

P = 154

Now the smaller one

P = 2 ( 7 * 6 )

P = 2 ( 42 )

P = 84

Now to find the full perimeter, add both perimeters together

P = 154 + 84

P = 238

238 meters

then add three to both sides:

-2t-3+3>5+3

simplify:

SOrry dont know buddy

Step-by-step explanation:

Answer/Step-by-step explanation:

The equation that relates the proportional quantities would take the following form ---› [tex] y = kx [/tex], where,

y = amount of Grape juice (dependent variable)

x = amount of Apple juice (independent variable)

k = constant of proportionality (y/x)

✔️Using any of the given pair, say, (5, 8),

Constant of proportionality = [tex] k = \frac{y}{x} = \frac{8}{5} = 1.6 [/tex]

Substitute k = 1.6 in [tex] y = kx [/tex].

An equation that represents the proportional relationship would be:

[tex] y = 1.6x [/tex]

Or

[tex] y = \frac{8}{5}x [/tex]

How the equation would change if:

y = amount of Apple juice (dependent variable)

x = amount of Grape juice (independent variable)

The constant of proportionality would change, that is using a pair, say, (8, 5),

[tex] k = \frac{y}{x} = \frac{5}{8} = 0.625 [/tex]

Substitute k = 0.625 in [tex] y = kx [/tex].

The equation would now be:

[tex] y = 0.625x [/tex].

Or

[tex] y = \frac{5}{8}x [/tex]
