Answer:

<em>m</em> = 2

General Formulas and Concepts:

<u>Algebra I</u>

Slope-Intercept Form: y = mx + b

  • m - slope
  • b - y-intercept

Perpendicular lines have a negative reciprocal slope.

Step-by-step explanation:

<u>Step 1: Define</u>

y = -1/2x + 4

<u>Step 2: Identify</u>

Slope <em>m</em> = -1/2

<u>Step 3: Solve</u>

<em>Reciprocate and multiply by negative</em>

<em>m</em> = 2

Solve. 2 (x - 1/2) = 3 (5 - 2x) show the steps in your solution.
viktelen [127]

Question 1.). Solve:

2 (x - 1 / 2) = 3 (5 - 2x)

Simplify both sides of equation:

2( x - 1 / 2 ) = 3(5 - 2x )

(2) (x) + (2) ( -1 / 2 ) = (3) (5) + (3) ( -2x )


Distribute:

2x + - 1 = 15 + -6x

2x - 1 = -6x + 15


Add 6x to both sides:

2x - 1 + 6x = -6x + 15 + 6x

8x - 1 = 15


Add 1 to both sides:

8x - 1 + 1 = 15 + 1

8x = 16


Divide both sides by 8:

8x / 8 = 16 / 8

Answer: 2 (x - 1 / 2) = 3 (5 - 2x) ==========> x = 2











Question 2.).

M =======> Amount Malik need

Solution: =========> m ≥ 5

Inequality ========> 8 + 7 + 10 + m ≥ 30

25 + m ≥ 30

Interpretation ==========> Malik needs at least, $5 .00 to get to, $30.00 or more.

Is the solution reasonable ===========> YES





Hope that helps!!!!! : )

Answer:

The third side is sqrt(77)

Step-by-step explanation:

Since this is a right triangle we can use the Pythagorean theorem

a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse

2^2 + b^2 = 9^2

4+ b^2 = 81

Subtract 4 from each side

b^2 = 81-4

b^2=77

Take the square root of each side

sqrt(b^2) = sqrt(77)

b = sqrt(77)

The third side is sqrt(77)

butalik [34]
Half of the people bought tickets at $1.50, $1.50 times 15 equals $22.50

The other half bought them at the regular price of $2.75, $2.75 times 15 equals $41.25

When we combine the two money totals, we end up with a grand total of $63.75
