I'm pretty sure the answer would be D... A triangle has three angles, and three sides. it already has to angles used and one left I guess...
Answer:
-21
Step-by-step explanation:
GIven data
We are given the equation of a line as
Y=-2x-21
let us compare this with the general equation of a line
y=mx+c
from the comparison, we can see that the intercept is -21
Therefore, the intercept is -21
Answer:
- equation: w +(2w -3) = 18/2
- length = 5 cm
- width = 4 cm
Step-by-step explanation:
Let w represent the width in cm. Then the length is 2w-3, 3 cm less than twice the width. The perimeter is twice the sum of these, so the sum of length and width is half the perimeter:
w + (2w -3) = 18/2
3w -3 = 9 . . . . collect terms
3w = 12 . . . . add 3
w = 4 . . . . divide by 3
2w-3 = 2·4 -3 = 5 . . . . length
The equation is w + (2w -3) = 18/2; the length is 5; the width is 4.
For this case we must find the point that Harold used to arrive at the following equation:
Starting from the fact that the equation of the point-slope form of a line is given by:
If we compare the standard equation with Harold's, we see that the slope of the line is 
In addition, it is observed that 
and 
Then, the correct option is: Harold used the point (7,0)
ANswer:
When Harold wrote his equation, the point was used (7,0).
Answer:
<em>x = 5/3 </em>or<em> x = -3</em>
Step-by-step explanation:
3x² + 4x - 15 = 0
Factor left side.
(3x - 5)(x + 3) = 0
Set factors equal to 0.
3x - 5 = 0
3x = 5
x = 5/3
x + 3 = 0
x = -3
