-2x + y =3
use 5 number and put it in above equation to find y, I will use -2,-1,0,1,2
x      y
-2   -1
-1    1
 0    3
 1    5
 2    7

Then draw the graph, find another point in the graph which intersect the slope, 
lets say i found (-3,-3)which is on the slope
to prove it, i put (-3,-3) in the equation -2x + y = 3
and i got 
3 = 3
Thus it is correct.

What is the radius of a sector of a circle with the central angle of measure 45 and whose area is 9/8 pi cm^2
larisa86 [58]

The radius of the sector of the circle with the given area is: B. 3.

<h3>What is the Area of a Sector?</h3>

Area of sector of a circle = ∅/360 × πr².

Given the following:

Area of sector = 9/8 π cm².

∅ = 45 degrees

Plug in the values into the formula

9/8π = 45/360 × πr²

1.125 = 0.125 × r²

1.125/0.125 = r²

9 =  r²

r = 3 cm

FIND VOLUME OF THE PYRAMID pls fast JUST ANSWER DONT EXPLAIN
cluponka [151]

Answer:

V = 211.56 mm

Step-by-step explanation:

The volume of a pyramid :

V = 1/3(Lenght * width * height)

Length = 9mm

Width = 8.2 mm

Height = 8.6 mm

Hence, we have ;

V = 1/3(9 * 8.2 * 8.6)

V = 1/3 * 634.68

V = 211.56 mm

For the function f(x) = -4x - 5, what are the outputs for the inputs -4, 1, 3, and 11?
Anika [276]

We have to find the output values for the given input values of the function given as,

  • f(x) = -4x - 5

Here, x = Input value of the function

And f(x) = Output values

By substituting the input values of x as,

For x = -4,

f(-4) = -4(-4) - 5

      = 16 - 5

      = 11

For x = 1,

f(1) = -4(1) - 5

    = -4 - 5

    = -9

For x = 3,

f(4) = -4(3) - 5

     = -17

For x = 11,

f(11) = -4(11) - 5

     = -44 - 5

     = -49

       Therefore, Option (A) will represent the output values for the given input values.
