Question 10(Multiple Choice Worth 1 points)

Mathematics

y = x − 6

y = 3x + 4

y is isolated in both equations, thus, you can set x - 6 and 3x + 4 equal to each other to solve for x.

x - 6 = 3x + 4

-2x - 6 = 4

-2x = 10

x = -5

Substitute -5 for x into either of the original equations to find y.

y = x - 6

y = -5 - 6

y = -11

Plug both x- and y-values into each original equation to check whether these values satisfy both equations.

y = x - 6 --> -11 = -5 - 6 --> -11 = -11 --> True

y = 3x + 4 --> -11 = 3(-5) + 4 --> -11 = -15 + 4 --> -11 = -11 --> True

Answer:

(−5, −11), because the point satisfies both equations.

we are given

Line A: y = x − 6

Line B: y = 3x + 4

so, we can solve it

we can set them equal

and then we can solve for x

y=x-6=3x+4

now, we can solve for x

-2x=10

x=-5

now, we can find y

y=-5-6

y=-11

so, we will get intersection points as

(x,y)=(-5,-11)

so, option-A........Answer

Which orderd pair is a solution to this equation? -2x-y=4
nevsk [136]
To find the ordered pair solution, you need to find the zero(s) (which are the x-values for which y is equal to zero). This is called the Zero Product Property. Here's the math:

-2x-y=4             convert the equation into slope form

-y=2x+4            multiply both sides by -1

y=-2x-4             convert into factored form

y=-2(x+2)          now, we need to find what x equals that makes y equal zero

0=-2(x+2)          replace y with zero

0/-2=x+2           divide both sides by -2

-2=x                  x=-2 when y=0

Therefore, the zero of the equation (aka the solution) is the ordered pair (-2,0). 

Answer: (-2,0)

If you have access to a graphing calculator, you can just convert the equation to y=mx+b form and enter it as a function. The solution is wherever the graph intercepts the x-axis. Hope this helps!

Find the maximum/minimum value of the function y = x2 - (5/3)x + 31/36.
AysviL [449]

Answer:

A

Step-by-step explanation:

Given a parabola in standard form, y = ax² + bx + c ( a ≠ 0 ), then

minimum/ maximum value is the y- coordinate of the vertex.

The x- coordinate of the vertex is

x_{vertex} = - \frac{b}{2a}

y = x² - \frac{5}{3} x + \frac{31}{36} ← is in standard form

with a = 1 and b = - \frac{5}{3} , thus

\frac{x}{vertex} = - \frac{-\frac{5}{3} }{2} = \frac{5}{6}

Substitute this value into y

y = (\frac{5}{6} )² - \frac{5}{3} (\frac{5}{6} ) + \frac{31}{36}

   = \frac{25}{36} - \frac{25}{18} + \frac{31}{36} = \frac{1}{6}

Since a > 1 then the vertex is a minimum, thus

minimum value = \frac{1}{6} → A

The real picture of my previous question is this​
Anastaziya [24]

Answer:

x = 120

Step-by-step explanation:

Assuming you require to find the value of x

The sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

Here n = 6 , then

sum = 180° × 4 = 720°

Sum the interior angles and equate to 720

140 + 150 + 90 + x + 130 + 90 = 720 , that is

x + 600 = 720 ( subtract 600 from both sides )

x = 120
