Find the distance from point A (-1/4,5)

to the line - x + 2y = 14. Round your answer to the nearest tenth.

Answers

Answer:

1.7 (units).

Step-by-step explanation:

1) if the point A has (-0.25;5) and the equation of the given line is -x+2y=14 (Ax+By+C=0), then the required distance can be calculated according to the formula:

[tex]d=\frac{Ax_0+By_0+C}{\sqrt{A^2+B^2} }[/tex]     , where A, B and C belong to the given line, x₀, y₀ - coordinates of the given point;

2) A=-1, B=2, C=-14 and x₀=-0.25, y₀=5, then according to the formula above:

[tex]d=|\frac{0.25+5*2-14}{\sqrt{4+1}}|=\frac{3.75}{\sqrt{5}}=\frac{3.75}{2.2}=1.7[/tex]

WHAT ARE CONGRUENCE LINES

Answers

Answer:

Line segments are congruent if they have the same length. However, they need not be parallel. They can be at any angle or orientation on the plane. ... Rays and lines cannot be congruent because they do not have both end points defined, and so have no definite length.

We can use the Pythagorean Theorum to find out the missing side because we have a 90 degree right angle and 2 sides already given to us.

The Pythagorean Theorem states that a^2 + b^2 = c^2

a in this case would be the shortest side,

b in this case would be the 2nd longest side,

c is the hypotenuse.

[tex]a^{2} + b^{2}= c^{2} \\a^{2} + 15^{2} = 17^{2}[/tex]

Subtract the linear expressions. (−2.6x+4.2)−(3.9x+2.5) What is the difference? Enter your answer in the box.

Answers

Answer:

-13x/2+1.7

Step-by-step explanation:

The difference of the given expression is - 6.5 x + 1.7.

Given that, (−2.6x+4.2)−(3.9x+2.5).

What is the subtraction of expressions?

To subtract an algebraic expression from another, we should change the signs (from '+' to '-' or from '-' to '+') of all the terms of the expression which is to be subtracted and then the two expressions are added.

Now, (−2.6x+4.2)−(3.9x+2.5)

= (-2.6x-3.9x)+4.2-2.5

= - 6.5 x + 1.7

Therefore, the difference of the given expression is - 6.5 x + 1.7.

Question 1 (2 points)

What is the product of 0.51 0.24? (2 points)

1) 0.1224

2) 1.124

3) 11.24

4) 1124

Answers

Answer:

0.52 x 0.24 means "about a half times 0.24". Given the multiple choice answers, the correct answer is therefore 0.1224 (since this is the only one smaller than 0.24).

Proof:

0.50 × 0.24 = 0.12

0.01 × 0.24 = 0.0024

And therefore 0.51 × 0.24 = 0.12 + 0.0024 = 0.1224

A rental car company charges $54.35 per day to rent a car and $0.09 for every mile driven. Jayden wants to rent a car, knowing that: • He plans to drive 425 miles. • He has at most $310 to spend. Use the drop-down menu below to write an inequality representing d, the total number of days Jayden can rent the car while staying within his budget.​

Answers

The inequality representing d, the total number of days Jayden can rent the car while staying within his budget is 54.35d + 38.25 ≤ 310

Given:

Charge per day = $54.35

Charge per mile = $0.09

Total miles = 425 miles

Amount to spend = at most $310

let

d = number of days

The inequality:

54.35 × d + 0.09 × 425 ≤ 310

54.35d + 38.25 ≤ 310

54.35d ≤ 310 - 38.25

54.35d ≤ 271.75

d ≤ 271.75 / 54.35

d ≤ 5 days

Therefore, the total number of days Jayden can rent the car while staying within his budget is 5 days
