Answer:

When x = -2 P ( -2 ; 5)

When x = -1 Q ( -1 ; 2)

When x = 0 R ( 0 ; 1)

Step-by-step explanation:

y = x² + 1

When x = -2

y = ( -2)² + 1 y = 5 point P ( -2 ; 5)

When x = - 1

y = ( -1)² + 1 y = 2 point Q ( -1 ; 2 )

When x = 0

y = (0)² + 1 y = 1 point R ( 0 ; 1 )

Answer the following questions. Make sure to show all your work.

a) Since the corresponding y-value is -0.6, hence the point (-0.8, -0.6) is a solution to the system of equations

b) since the corresponding x-value is not 1/3, hence the point (1/3, 2) is not a solution to the system of equation

In order to show if the given point corresponds to the given function, we will have to substitute the value of x into the function to see if we will have its corresponding y-value

For the point (-0.8, -0.6), substitute x = -0.8 into both functions as shown:

f(x) = 2x + 1

f(-0.8) = 2(-0.8) + 1

f(-0.8) = -1.6 + 1

f(-0.8) = -0.6

Simiarly;

y = -3(-0.8)- 3

y = 2.4 - 3

y = -0.6

Since the corresponding y-value is -0.6, hence the point (-0.8, -0.6) is a solution to the system of equations

For the point (1/3, 2), substitute x = 1/3 into both functions as shown:

x = (y+2)/2

x = (2+2)/2

x = 4/2

x = 2

Simiarly;

x + 2 = 3

x = 3-2

x = 1

Since the corresponding x-value is not 1/3, hence the point (1/3, 2) is not a solution to the system of equations

Match the base to the corresponding height. Base (b) Height (h) b b h b

antiseptic1488 [7]

Answer: See the diagram below

=================================================

Explanation:

The base is always perpendicular to the height, meaning the two form a 90 degree angle (aka right angle).

In column 1, refer to the figures as 1, 2 and 3 (working top to bottom).

In column 2, refer to the figures as A, B, C

Figure 1 matches with figure B

Figure 2 matches with figure C

Figure 3 matches with figure A.

These matches are of course the base with the proper height.
