Answer:

x=80, y=15

Step-by-step explanation:

The angle on the opposite side of 100 will be equal to x

We know it is 180-100 so x=80

We know 6y=90

therfore y = 90/6 which equals 15

so y=15 and x=80

<em>ANSWER:</em>

<u>since the angles have to all equal 360 </u><em><u>x = 80. and 6y= 90.</u></em>

What is f(-3) for the function f(a). =-2ax2-5a+4
Nataly_w [17]

The value of function f(x). =-2ax² -5a + 4 at a = -3 will be -23a + 2.

<h3>What is a function?</h3>

The machine will only accept specified inputs, described as the function's domain, and will potentially produce one output for each input.

For example y = sinx ,  y = x + 3 ets.

Given,

f(x)  = - 2ax² -5a + 4

x = -3

f(-3) =  - 2a(-3)² -5a + 4

f(-3) = -18a - 5a + 4

f(-3) = 23a + 2

Hence the value of function f(x). =-2ax² -5a + 4 at a = -3 will be -23a + 2.

QUICKKKK EXPERTS/ACE (and people that know it for sure comment) Brainiest Marked to the first correct answer
Olin [163]
I worked them out separately if I'm correct, then the order is:

x+5y=-2
x+5y=4  These are Inconsistent

y=3x+4
-2x+y=4   These are Consistent independent

3x+y=4
-6x-2y=-8 These are coincident

Inconsistent lines=No solution
Coincident lines=exactly on top of each other
Consistent Independant= Solution, as they cross each other. 

~Hope this helps!
