Consider the line y=5/7x+7. Find the equation of the line that is parallel to this line and passes through the point (-5,-2). Fi
butalik [34]

Step-by-step explanation:

m=5/7

m1=m2=5/7

L;y-(-2)=5/7(x-(-5)

y+2=5/7(x+5)

7y+14=5X+25

7y-5x=11 is parallel lines

m1*m2=-1 is perpendicular lines

m2=-1*7/5

m2=-7/5

L;y+2=-7/5(x+5)

5Y+10=-7x-35

5y+7x=-45 is perpendicular lines

Doc Brown’s DeLorean has three crucial systems that are required for a successful trip: combustion engine, time circuits, and fl
Nesterboy [21]

Step-by-step explanation:

The total probability that the DeLorean makes the trip is:

P = P(engine) × P(at least 1 time circuit) × P(at least 2 capacitors)

P = P(engine) × (1 − P(0 time circuits)) × P(at least 2 capacitors)

P = 0.94 × (1 − ₄C₀ 0.75⁰ 0.25⁴) × (₃C₂ 0.8² 0.2¹ + ₃C₃ 0.8³ 0.2⁰)

P = 0.94 × (1 − 0.25⁴) × (0.384 + 0.512)

P = 0.83895

The reliability of the DeLorean is approximately 83.9%.

I need help with this questions, please help ill mark brainliest..
Natasha_Volkova [10]

Answer:

Options (1), (3) and (5)

Step-by-step explanation:

Equation that represents the relationship between the three sides of a triangle is,

a² + b² = c²

Where c = longest side of the triangle

If the length of the given sides satisfy the equation, triangle formed by the sides will be a right triangle.

Option A.

27 in, 36 in, 45 in

(45)² = (27)² + (36)²

2025 = 729 + 1296

2025 = 2025

True.

Option 2.

18 in, 22 in, 28 in

(28)² = (18)² + (22)²

784 = 324 + 484

784 = 808

False.

Option 3

10 in, 24 in, 26 in

(26)² = (10)² + (24)²

676 = 100 + 576

676 = 676

True.

Option 4

20 in, 21 in, 31 in

(31)² = (20)² + (21)²

961 = 400 + 441

961 = 841

False.

Option 5

28 in, 45 in, 53 in

(53)² = (28)² + (45)²

2809 = 784 + 2025

2809 = 2809

True.

Therefore, Options (1), (3) and (5) will be the correct options.
