Answer:
Step-by-step explanation:
We want to find a quadratic that passes through the points:
In intercept form.
First, note that the first two given points are the <em>x</em>-intercepts of our quadratic. Intercept or factored form is given by:
Where <em>p</em> and <em>q</em> are the <em>x</em>-intercepts, and <em>a</em> is the leading coefficient.
So, we will substitute -4 and 2 for <em>p</em> and <em>q: </em>
Simplify:
Next, the third point (6, -20) tells us that <em>y</em> = -20 when <em>x</em> = 6. So:
Solve for <em>a: </em>
Thus:
Hence, our equation in intercept from is:
Answer:
Minus a ? I dont get it. While a linear equation is a equation between two variables that gives a straight line when plotted on a graph.
Answer:
The length is 42 inches and the width is 14 inches
Step-by-step explanation:
You know the width is 1/3 of the length, and the length is basically the longer side of a rectangle. The width is y-4, so multiply using distributive property to get 3y-12.
You now know that the 2y+6 is equal to 3y-12, so you add 12 to both sides using additive property of addition to get 2y+18=3y.
Then you subtract 2y from both sides to get the unit value of y.
Y is equal to 18.
Then you can plug 18 into the y's to get
2(18)+6 which is 36+6 = 42
18-4 = 14
There you go.
The length is the longer side which is 42 inches and the width is 14 inches
Hope this helps!
11/6+3 is 29/6. 2/(29/6) is 12/29, which is the answer.
