Answer:

∠ b = 23°

Step-by-step explanation:

Complementary angles sum to 90° , then

a + b = 90° , that is

67° + b = 90° ( subtract 67° from both sides )

∠ b = 23°

Factor the following polynomial completely. 2x2 – 10x – 28

erastovalidia [21]

Answer:

2(x - 7)(x + 2)

Step-by-step explanation:

Given

2x² - 10x - 28 ← factor out 2 from each term

= 2(x² - 5x - 14) ← factor the quadratic

Consider the factors of the constant term (- 14) which sum to give the coefficient of the x- term (- 5)

The factors are - 7 and + 2 , since

- 7 × 2 = - 14 and - 7 + 2 = - 5 , thus

x² - 5x - 14 = (x - 7)(x + 2) and

2x² - 10x - 28 = 2(x - 7)(x + 2)

PLEASE HELP ME!!!

Answer:

$350 * D \geq 1400$

$D\ge 4$

This means that the family must travel for at least 4 days.

Step-by-step explanation:

Given

$Rate = 350\ miles\ daily$

$Distance = 1400\ miles\ (atleast)$

Required

Determine and solve the inequality

The number of days is represented with D

So:

On any D number of days, the family would have covered a distance of 350 * D miles

If the total distance is at least 1400, then the inequality is:

$350 * D \geq 1400$

[The term "At least" is used to represent greater than or equal to]

$350 * D \geq 1400$

Divide through by 350

$\frac{350 * D}{350} \ge \frac{1400}{350}$

$D \ge \frac{1400}{350}$

$D\ge 4$

This means that the family must travel for at least 4 days.
