PLEASE HELP

Mathematics

part A-

3t + .80m = 18 (t - tickets) (m - meals)

we already know m = 15 so our equation would turn into

3t + .80(15) = 18

3t + 12 = 18


part B-

3t + 12 = 18

subtract 12 from both sides

3t + 12 = 18

-12 -12

then, 3t= 6

and, we know 3 goes into 6 two times meaning t=2


part C- Erica purchased 2 movie tickets last month

15 meals x $0.80 = $12.
$18 - $12 = $6.

If one movie ticket is $3 then she must have purchased 2 with $6.

Part A - 15x0.8=18-x=x

Part B-
15 x 0.8 = 12
18- 12=6

Part C- 2

Solve the equation 5x-2x^2+1
Pani-rosa [81]

Answer:

Step-by-step explanation:

If you call "5x-2x^2+1" an "equation," then you must equate 5x-2x^2+1 to 0:

5x-2x^2+1 = 0

This is a quadratic equation.  Rearranging the terms in descending order by powers of x, we get:

-2x^2 + 5x + 1 = 0.  Here the coefficients are a = -2, b = 5 and c = 1.

Use the quadratic formula to solve for x:

First find the discriminant, b^2 - 4ac:  25 - 4(-2)(1) = 25 + 8 = 33

Because the discriminant is positive, the roots of this quadratic are real and unequal.

                                                             -b ± √(discriminant)

Applying the quadratic formula   x = --------------------------------

                                                                         2a

we get:

      -5 ± √33           -5 + √33

x = ----------------- = --------------------- and

           2(-2)                     -4

                                  -5 - √33

                                 ---------------

                                         -4

Write an equation of the line in slope-intercept form: y-intercept of 2, x-intercept of 4
zvonat [6]

Answer:

\sf y=-\dfrac12x+2

Step-by-step explanation:

y-intercept is when x = 0, so (0, 2)

x-intercept is when y = 0, so (4, 0)

\sf slope=\dfrac{change\:in\:y}{change\:in\:x}=\dfrac{0-2}{4-0}=-\dfrac12

Slope-intercept form of linear equation:  \sf y=mx+b

(where m is the slope and b is the y-intercept)

Given:

  • \sf m=-\dfrac12
  • b = 2

\sf \implies y=-\dfrac12x+2
