olga2289 [7]3 years ago
6 0

Answer:

  • 3x² + 5x + 1 = 0 simplified
  • x = (-5 ± \sqrt{13})/6 roots

Step-by-step explanation:

<u>Given quadratic formula</u>

  • 3x² + 5x - 5 = - 6

<u>Standard form</u>

  • ax² + bx + c = 0

<u>Simplifying</u>

  • 3x² + 5x - 5 + 6 = 0
  • 3x² + 5x + 1 = 0

<u>Solving</u>

  • x = (-5 ± \sqrt{5^2 -4*3*1})/(2*3)
  • x = (-5 ± \sqrt{13})/6

Which side of DEF is the longest ? Please help
Minchanka [31]

∠D= 87°, ∠E = 50°

Sum of three angles in a triangle is 180°

∠F = 180 - (∠D + ∠E)

∠F = 180 - (87 + 50)

∠F = 180 - 137

∠F = 43°

Side opposite to greatest angle is the longest side.

Among angle D, E and F, angle D is the greatest angle

So side opposite to angle D is the longest side which is EF

Option B is the answer

Need help please would really be greatful
Rainbow [258]

Answer:

122°  

Step-by-step explanation:

The formula for finding the sum of all angles in a polygon is:

(n-2) * 180°

n is the number of angles

Here n = 7, so the sum of all angles is

(7-2) * 180°  = 900°

x = 900 - 128 - 130 - 120 - 115 - 145 - 140 = 122°

Make me the brainliest ;)

Sal's Sandwich Shop sells wraps and sandwiches as part of its lunch specials. The profit on every sandwich is $2, and the profit
Volgvan

Answer:

  • See below

Step-by-step explanation:

<u>Given equation:</u>

  • 2x + 3y = 1470

<u>Change to slope-intercept form:</u>

  • 2x + 3y = 1470, isolate y
  • 3y = -2x + 1470, divide all terms by 3
  • y = -2/3x + 490

The slope is -2/3 and y-intercept is 490

<u>Functional notation, change y to f(x)</u>

  • f(x) = -2/3x + 490

To graph the line, plot the intercepts and connect with the line.

<u>If the total is $1593 for the next month, the function would be:</u>

  • 2x + 3y = 1593

<u>Changing to slope-intercept:</u>

  • y = -2/3x + 531

The slopes are same, therefore the lines are parallel.

The difference is the y-intercept, it is greater in the next month.

The graphs are attached, with intercepts shown.
