(-9, 3) will be x2 and y2

The formula is

Distance = $\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Substitute in all the variables.

$\sqrt{(-9-1)^2+(3-(-2))^2}$

Solve.

$\sqrt{(-10)^2+5^2}$

Which of the binomials below is a factor of this trinomial? 10x^2+27x-28

Mumz [18]

Option A is correct i.e 2x+7 is a factor of trinomial $10x^2+27x-28$

Step-by-step explanation:

We need to find the factor of the trinomial $10x^2+27x-28$

Factoring:

$10x^2+27x-28\\=10x^2-8x+35x-28\\=2x(5x-4)+7(5x-4)\\=(2x+7)(5x-4)$

So, the factors are (2x+7) and (5x-4)

So, Option A is correct i.e 2x+7 is a factor of trinomial $10x^2+27x-28$

Noor wants to spend less than \$20$20dollar sign, 20 on condiments. Each kilogram of salt costs \$1.50$1.50dollar sign, 1, point

ludmilkaskok [199]

Answer:

1.5 S + 2.5 P < 20

Step-by-step explanation:

We are given that each kilogram of salt costs \$1.50$1.50dollar sign, 1, point, 50, and each kilogram of pepper costs \$2.50$2.50dollar sign, 2, point, 50.

How can we express the total cost of the number of kilograms of salt and pepper Noor can buy on her budget?

Hint #22 / 3

The cost of SSS kilograms of salt is 1.5 S, point, 5, S, and the cost of P kilograms of pepper is 2.5 P, point, 5, P. Therefore, the total cost of buying some kilograms of salt and pepper is 1.5 S +2.5 P, point, 5, S, plus, 2, point, 5, P.

We are also given that Noor wants to spend less than \$20 dollar sign, 20 on groceries. Let's use this condition to create the appropriate inequality.

The following inequality represents the number of kilograms of salt and pepper Noor can buy on her budget:

Hint; (S) (P) make sure to write the letters CAPITAL or u would get it wrong if u write small letter s or p. (S) (P)
