Answer:

y=-1

Step-by-step explanation:

We have been given an equation y=-2x+1. We are asked to complete the given table using our given equation.

We can see that our given table has two columns namely x and y.

To find the value of y for given values of x, we need to substitute the given x value in our equation.

Substituting x=0 in our equation we will get,

y=-2*0+1

y=0+1

y=1

Therefore, the value of y for first row is 1 and ordered pair will be (0,1).

Substituting x=-3 in our equation we will get,

y=-2*-3+1

y=6+1

y=7

Therefore, the value of y for 2nd row is 7 and ordered pair will be (-3,7).

Substituting x=1 in our equation we will get,

y=-2*1+1

y=-2+1

y=-1

Therefore, the value of y for 3rd row is -1  and ordered pair will be (1,-1).

We are given the equation of a line

y = -2x + 1

We have to find the value of y at three different values of x i.e. at x =0, -3 and 1

In order to find the value of y at any given x, simply replace x by that number.

So, for x=0, we will replace x by 0 to find the value of y. So y will be:
y = -2(0) + 1
y = 1
This can be expressed as an ordered pair as (0,1)

Similarly for x=-3, we get:
y = -2(-3) + 1 = 6 + 1
y = 7
This can be expressed as an ordered pair as (-3, 7)

And, finally for x=1, we get:
y= -2(1) + 1 = -2 + 1
y= -1
This can be expressed as an ordered pair as (-1, -1)

What is the total surface area of the rectangular pyramid whose net is shown?
Lunna [17]

Answer:

95 in.²

Step-by-step explanation:

Total surface area of the rectangular pyramid = 4(area of triangle) + area of rectangle

Area of triangle = ½*base*height

base = 5 in.

height = 7 in.

Area of triangle = ½*5*7 = 17.5 in.²

Area of rectangle = Length*width = 5*5 = 25 in.²

Plug in the values

Total surface area of the rectangular pyramid = 4(17.5) + 25

= 95 in.²
