Answer:

The slope is: A. -2

Step-by-step explanation:

Given points: (5, -11), (-9, 17)

Use the equation for slope:

m = y - y1 / x - x1

m = -11 - 17 / 5 - (-9)

m = -28 / 14

m = -2

Hope this helps! Have an Awesome Day!! :-)

Kryger [21]

Answer:

<h2>125 tickets for an adult</h2><h2>and 175 tickets for a student</h2>

Step-by-step explanation:

$a-\text{number of the tickets for an adult}\\s-\text{number of the tickets for a student}\\\\(1)\qquad a+s=300\\(2)\qquad4.5a+3s=1087.5\\------------\\(1)\\a+s=300\qquad\text{subtstitute}\ s\ \text{from both sides}\\a=300-s\\\\\text{Put it to (2):}\\\\4.5(300-s)+3s=1087.5\qquad\text{use distributive property}\\\\(4.5)(300)+(4.5)(-s)+3s=1087.5\\\\1350-4.5s+3s=1087.5\qquad\text{subtract 1350 from both sides}\\\\-1.5s=-262.5\qquad\text{divide both sides by (-1.5)}\\\\\boxed{s=175}$

$\text{Put the value of}\ s\ \text{to (1):}\\\\a=300-175\\\\\boxed{a=125}$

ASHA 777 [7]

Answer:

16666.25

Step-by-step explanation:

For rounded values, the minimum value they could have been rounded from is the given value less half its least-significant digit.

That means the minimums are ...

a: 340 ⇒ 340 -5 = 335

b: 49.8 ⇒ 49.8 -0.05 = 49.75

Then the minimum product would be ...

(335) × (49.75) = 16666.25

egoroff_w [7]

Here to solve the equation we need to plug in the value y as given. -5x+2(7x)=9. -5x+14x=9. 9x=9. X=1.
