Two lines, A and B, are represented by equations given below: Line A: y = x − 2 Line B: y = 3x + 4 Which of the following shows

the solution to the system of equations and explains why? (1 point) a (−3, −5), because the point does not lie on any axis b (−3, −5), because the point satisfies both equations c (−4, −8), because the point satisfies one of the equations d (−4, −8), because the point lies between the two axes

The solution to the system of equations is (-3, -5) because the point satisfies both equations

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

A linear function is in the form:

y = mx + b

Where m is the slope (rate of change) and b is the y intercept

Line A:

y = x − 2  (1)

Line B:

y = 3x + 4   (2)

Solving both equations simultaneously gives:

x = -3, y = -5

The solution to the system of equations is (-3, -5) because the point satisfies both equations

Lines K and N are perpendicular If the slope of line K is -6, what is the slope of Line N
djverab [1.8K]

line N has slope m = \frac{1}{6}

given a line with slope m then the slope of a line perpendicular to it is

m_{perpendicular} = - \frac{1}{m}


thus line N has slope - \frac{1}{- 6} = \frac{1}{6}

I’m a bit confused here
alekssr [168]
Y= -x and y= -1/x
Are one-one
y= -x, inverse x= -y
Identify function
hence, inverse of y= -x in y= -x
similarly in the case of y= -1/x
so option (D) I and II, only

What is the value of the discriminant?<br> 2K2 = 10k - 2
Phoenix [80]

Answer:

84

Step-by-step explanation:

Given a quadratic equation in standard form, ax² + bx + c = 0 : a ≠ 0

Then the discriminant is Δ = b² - 4ac

2k² = 10k - 2 ( subtract 10k - 2 from both sides )

2k² - 10k + 2 = 0 ← in standard form

with a = 2, b = - 10 and c = 2, thus

b² - 4ac = (- 10)² - (4 × 2 × 2) = 100 - 16 = 84

What 2 numbers can be added to make 16 as well as multiplied to make -36
Sladkaya [172]

Answer:

18 and -2

Step-by-step explanation:

Let x = 1st no.

y = 2nd no.

(1)    x + y = 16            (2)     xy = -36

           y = 16 - x                 x(16 - x) = -36

                                           16x - x^{2} = -36\\x^{2}  - 16x - 36 = 0\\

                                           (x - 18)(x + 2) = 0

                                               x = 18   or x = -2

          y = 16 - 18 = -2

         y = 16 -(- 2) = 16 + 2 - 18

The two numbers are 18 and -2
