960 dollars because 5 times 3 is 15. 15 times 8 is 120. 120 times 8 is 960
Part 1.
The slope is found by the change in Y over the change in X.
In the picture they are finding the difference between the X and Y of each point. They have x1 - y1 over x2-y2, when it should be y2-y1 / x2 - x1.
Part 2:
Slope = Change in Y over change in X:
(4 - 6) / (0 - -2) = -2 / 2 = -1
Slope = -1
Using the point (0,4) tells you the Y-intercept, which is the Y value when x is 0. The Y intercept is added to the slope when writing the equation of a line in point slope form.
The equation is y = -x +4
Part 3:
Find two points on the line by replacing X with 0 and solving for Y and then replace Y with 0 and solve for X. This gives you the X and Y intercepts. Once you have those two points, put them on a graph and then draw a straight line through both dots.
Answer:
option 3
Step-by-step explanation:
Larger the value of '' a '' makes the parabola narrow.
A positive value of '' a '' which is close to 0 makes the parabola wide.
<em><u>To find the widest graph , find the smallest </u></em><em><u>a</u></em><em><u>. (or </u></em><em><u>a</u></em><em><u> closest to zero)</u></em>
option 1
option 2
option 3
option 4
Positive and negative value of ' a ' decides the direction the parabola opens.
But we have to find the widest parabola irrespective of the direction.
So we will find the smallest ' a '

Answer:
perimeter = 4x³ + 3x² + 2
Step-by-step explanation:
perimeter = sum of the lengths of the sides
perimeter = 2x³ + 3x³ - x² - x³ + 4x² + 2
perimeter = 4x³ + 3x² + 2
