The ordered pair is (-2, -3)

Step-by-step explanation:

Step 1: To find whether an ordered pair is a solution, substitute values of x and y and see whether it satisfies the equation.

(-3, -2) ⇒ 7 × -3 - 5 × -2 = -21 + 10 = -11 ≠ 1

(-2, -3) ⇒ 7 × -2 - 5 × -3 = -14 + 15 = 1

(0, 4) ⇒ 0 - 5 × 4 = 20 ≠ 1

(4, 0) ⇒ 7 × 4 - 0 = 28 ≠ 1

So the ordered pair is (-2, -3)

The area (in square inches) of a rectangle is given by the polynomial function A(p) = p2 + 9p + 20. If the length of the rectang

boyakko [2]

Answer:

$Width = p + 4$

Step-by-step explanation:

Given

$Area = p^2 + 9p + 20$

$Length = p + 5$

Required

Determine the width

The area of a rectangle is:

$Area = Length * Width$

This gives:

$p^2 + 9p + 20= (p+5)* Width$

Expand

$p^2 + 4p + 5p + 20= (p+5)* Width$

Factorize

$p(p + 4) + 5(p + 4)= (p+5)* Width$

$(p + 5) (p + 4)= (p+5)* Width$

Divide both sides by p + 5

$p + 4= Width$

$Width = p + 4$

Suppose you just flipped a fair coin 8 times in a row and you got heads each time! What is the probability that the next coin fl

Svetllana [295]

Answer:

The probability is 1

Step-by-step explanation:

Given

Number of flips = 8

Outcomes = 8 heads

Required

Probability of getting a head in the next row

This problem can be attributed to experimental probability and it'll be solved using experimental probability formula, which goes as follows;

$Probability = \frac{Number\ of\ Occurence}{Total\ Trials}$

Let $P(Head)$ represents the probability of getting a head in the next row;

$P(Head)= \frac{Outcome\ of\ head}{Total\ Flips}$

$P(Head)= \frac{8}{8}$

$P(Head)= 1$

Hence, the probability of obtaining a head in the next flip is 1

What is P = 2a + 2b for a

stiks02 [169]

The answer to b is:

b = p/2 - a

the answer to a is:

a= p - 2b/2

Solve for p in the literal equation 5p+2r=q

Katen [24]

5p+2r=q

Move variable to the right
5p=q -2r
Divide both sides of the
equation by 5

q - 2
p =— — r
5 - 5

The final solution for
p is

q - 2
p =— — r, rER, qER
5 - 5
