Answer:
x = 20
Step-by-step explanation:
I don't see a y in the diagram.
The 3 angles x, 90 and (4x - 10) lie on the line EF and sum to 180°, so
x + 90 + 4x - 10 = 180, that is
5x + 80 = 180 ( subtract 80 from both sides )
5x = 100 ( divide both sides by 5 )
x = 20
from the equation<span> x^2 - 6x + 7 = 0 </span>, b is equal to -6. The form should become y = (x-(b/2)^2) + c. (<span>b/2)^2 is equal to 9. Hence,
</span>
0 = (x - 3)^2 -9 + 7
<span>0 = (x - 3)^2 -2
</span>2 = <span>(x - 3)^2
x should be equal to -1.5858 and -4.4142</span>
Point slope is a really easy form for linear equations. It lets you plug in the numbers from a cordinate that the line passes through on the graph and the slope directly. Here is the point slope equation:
(The (2) and (1) next to the x's and y's are suposed to be underneath them. There is also supposed to be an extra parentheses at the end.)
You would replace y(1) with the y value, x(1) with the x value, and m with the slope. For example, if you have a line that crosses through the point (6, 10) with a slope of 3, this is how you would write the equation of the line in point slope form:
Now, for this problem, we have the point (1, 4) with a slope of 2. This is the point slope form for the given point and slope:
The values of y1 and x1 are the values we plugged into this equation, 4 and 1.
Answer:
See below
Step-by-step explanation:
Lets do the long division:-
- x - 5
-------------------
x + 4 ( -x^2 - 9x - 20
-x^2 - 4x Subtract:-
------------
-5x - 20
-5x - 20
The quotent is -x - 5 with no remainder so the graph will be a straight line with negative slope of -1, and y-intercept at (0, -5).
Answer:
200 is 10 times as much as 20 and 1 tenth of 2,000
Step-by-step explanation:
Divide 200 by 10 and you'll get 20 and multiply it by 10 to get 2,000.
