C(t) = $2t + $8

This tells us that the basic cost of the pizza is $8, with no toppings, and that each topping costs an additional $2.

To graph this, plot a dot at (0,$8). Now move y our pencil point 1 unit to the right and then 2 units up. Plot a dot at this new location. Now draw a straight line connection (0, $8) and this new location (which is (1, $10) ).

Solve x2 + 2x = 4 for x by completing the square. x equals plus or minus square root of 5 plus 1 x equals plus or minus square r

steposvetlana [31]

Answer:

x equals plus or minus square root of 5 minus 1

Step-by-step explanation:

we have

$x^{2} +2x=4$

Divide by 2 the coefficient of the x-term

$2/2=1$

squared the number

$1^2=1$

Adds both sides

$x^{2} +2x+1=4+1$

$x^{2} +2x+1=5$

Rewrite as perfect squares

$(x+1)^{2}=5$

take the square root both sides

$x+1=(+/-)\sqrt{5}$

$x=(+/-)\sqrt{5}-1$

therefore

x equals plus or minus square root of 5 minus 1

umka21 [38]

If each person got 1/6 then there is still 2/6 left over, =1/3. In fraction strips, we would do

1/6 1/6 1/6 1/6 1/6 1/6 for the overall tomato and then 1/6 1/6 for the remaining piece of the tomato.

Gerber Product's Gerber Mixed Cereal for Baby contains, in each serving, 60 calories and 11 grams of carbohydrates†. Gerber Mang

yulyashka [42]

Answer:

Gerber mixed cereal for baby 1 servings and Gerber mango tropical fruit dessert 2 servings

Step-by-step explanation:

calories = 60 + 80 + 80 = 220

grams of carbohydrates = 11 + 21 +21 = 53

this is probably easy to guess, but the way to do it it's the following

first see the units you need, for example in 53g

to get that 3 with the numbers you have to sum ( 21, 11) you need to sum 3, 13, etc, numbers (because you only have ones)

then you look at the tens in 53, and you finish to figure out that you can only sum 3 numbers, and that, to get that 5, they need to be two 21 and one 11.

that means the only way to get that amount of carbs is with 1 serving of Gerber mixed cereal for babyand and 2 servings of Gerber mango tropical fruit dessert.

Then you need to check that the amount of calories in that servings it's the required too. 60 + 80 + 80 = 220
