The area for the trapzoid is 102.3
Answer:
It does not intersect the x axis
Step-by-step explanation:
If there are no real roots the quadratic does not intersect the x axis
If there is one root it touches the x axis
2 real roots it crosses twice
Well, let's first square 3.5x10^4 which is 1,225,000,000
Scientific notation is when you put a decimal place after the first digit and then say the answer is that multiplied by 10 to a power. This power is the number of digits that come after the first. In this case, the power should be 9 (if you count the 225 and all the 0's, you'll count 9 numbers).
Thus the answer is 1.225x10^9
Answer : -9/10
-4/5 times 9/8 = -36/40
Then simplify that you get -9/10
You can graph that by looking at the y-intercept first. That's where you start to put a point in the coordinate plane or graph.
So go down 1 below 0.
Next, look at the slope.
We know that y = -2x - 1 is in slope intercept form (y = mx+b)
So -2 is our slope. It will be -2/1 because we need a fraction to graph the rise over run and all whole numbers can be a fraction by making 1 as their denominator.
Look at the attachment.
Starting from -1 (y-intercept), go down 2 (-2) then right 1 (1).
To complete the line above, keep the same value and reverse their sign/symbol. So -2/1 will be 2/-1. It goes up 2 then left 1.
I hope you understand and find this answer the most helpful! :)
