<span>2x-3y=-8   /* 2    -------> 4x -6y = -16
9x+2y=-5  /*3    --------> 27x +6y = -15

</span>4x -6y = -16
<span>27x +6y = -15
</span>
31x        = -31
x = -1

2x-3y=-8 
2*(-1) - 3y = -8
-2 - 3y = -8
-3y = -6
y = 2

x= -1, y = 2

(-1,2)

Check:
2(-1)-3*2=-8   -----> - 2 - 6 = -8 ----> -8 = -8 True
9x+2y=-5  -------> 9(-1) +2*2 = -5 ------> - 5 = -5 True

So, solution is (-1,2).

Question 1 of 15
Mrac [35]

The function y = - 50x + 75 is linear. So, the correct option is (A).

<h3>Define linear function.</h3>

The formula for a linear function is f(x) = mx + b, where m and b are real values. Isn't it resembling the slope-intercept form of a line, represented by the equation y = mx + b? Yes, this is the case as the graph of a linear function is a line. Here,

The line has a slope of m and a y-intercept of b.

The independent variable is "x."

The dependent variable is "y" (also known as f(x)).

Consider the equation y = - 50x + 75

Compared to the linear function equation, we get

m = -50

b = 75

So, the function is a linear function with a constant change. The function will be linear at all points.

Find the measure of the angle HELP PLSSS URGENT!
Alecsey [184]

Answer:

It is 40 degrees

Step-by-step explanation:

The 2 lines, x and y are forming 90 degrees, and since we know that part of that complementary angle is 50 degrees, we would do:

50+x=90

-50    -50

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

x=40

If f(x)=-7x-3 and g(x)=√x-16 what is (f °g)(-2)
schepotkina [342]

Answer:

Not possible

Step-by-step explanation:

The notation (f °g)(-2) means f(g(-2)). You will substitute -2 into g(x) then substitute the value or equation that results into f(x).

g(-2) = √x - 16 = √-2 - 16

This is not possible because the value of -2 cannot be found in a square root. Square roots do not compute real roots for negative numbers.
