Answer:

B. -111

Step-by-step explanation:

y = -4x^2 - 3x + 4

x = 5

y = -4(5)^2 - 3(5) + 4

y = -4(25) - 15 + 4

y = -100 - 15 + 4

y = -111

...............................................................................................................................................

Please, write -4x^2 (not 04x2).

Then the quadratic model is y = -4x^2 - 3x + 4.

Now substitute 5 for x: y(5) = -4 (5)^2 - 3(5) + 4

Simplifying, y(5) = -4(25) - 15 + 4 = -100 - 11 = -111.

Answer:

All you need to remember is the rules

Step-by-step explanation:

Let us remember

a to the m power x a to the nth power is = a to the m+n power. (add the exponents)

And

a to the m power ÷ a to the nth power is = a to the m-n power. (subtract the exponents) So

14 to the -4 power x 14 to the 7 power= 14 to the -4+7 which is equal to 14 to the 3rd power

Ella has 1/3 as many trading cards as Kip. Adira has 3 more than 50% of the number of cards that Kip has. Kip has 18 cards.

Answer:

3e = k

2a - 6 = k

k = 18

we can plug in k first for each equation

3e = 18

e = 6

2a - 6 = 18

a = 12

k = 18

e = 6

a = 12
