Complete question:
y = 2x² + 2x - 3
x = -2 -1 0 1 2
Answer:
<u>Complete table of values</u>
x: -2 -1 0 1 2
y: 1 -3 -3 1 9
Step-by-step explanation:
Given;
y = 2x² + 2x - 3
To complete the table of values of the equation above, we substitute the value of x into the given equation and solve for y.
when, x = -2
y = 2(-2)² + 2(-2) - 3
y = 8 - 4 - 3
y = 1
when x = -1
y = 2(-1)² + 2(-1) - 3
y = 2 - 2 - 3
y = -3
when x = 0
y = 2(0)² + 2(0) - 3
y = 0 - 0 - 3
y = -3
when x = 1
y = 2(1)² + 2(1) - 3
y = 2 + 2 - 3
y = 1
when x = 2
y = 2(2)² + 2(2) - 3
y = 8 + 4 - 3
y = 9
<u>Complete table</u>
x: -2 -1 0 1 2
y: 1 -3 -3 1 9

Required expression for one-eight of the sum of a number and three is
<u>Solution:
</u>
Given that unknown value is represented by variable x.
Need to create algebraic expression for One-eight of the sum of a number and three.
Let’s first find one eight of the number that is 1/8th of x =
Now on adding three we get
Hence required expression for one-eight of the sum of a number and three is
C
A line with undefined slope is a vertical line parallel to the y-axis, passing through all points with the same x-coordinate.
For this reason it's equation is x = c
where c is the value of the x-coordinate the line passes through
For (- 3, 5 ) the x-coordinate is - 3, hence
x = - 3 → is the equation of the line
Answer:
2/3
Step-by-step explanation:
7/9 - 2/8 x 4/9
Reduce the fraction.
7/9 - 1/4 x 4/9
Reduce the numbers:
7/9 - 1/9
Subtract the fractions.:
6/9 > 2/3
