Answer:
P (5 , 10)
Step-by-step explanation:
point A (1,4) and point D (7,13), AP/PD = 2:1
P (x,y) : x = x₁ + (a/(a+b) * (x₂-x₁)) y = y₁ + (a/(a+b) * (y₂-y₁)) .... a=2 b=1
x = 1 + 2/(2+1) * (7-1) = 5
y = 4 + 2/(2+1) * (13-4) = 10
P (5 , 10)
Answer:
x/8x+8 domain is the set of all real numbers except -5/3
Answer:
undefined
Step-by-step explanation:
To find the slope of the line between two points, use the slope formula
.
and
represent the x and y values of one point the line passes through, and
and
represent the x and y values of another point the line also passes through. Therefore, use the x and y values of the points (0,3) and (0,4) to find the slope. Substitute them into the formula in the right order:
However, we can't divide 1 by 0. Therefore, the slope is undefined. (You could also graph the points to see that they form a vertical line, and all vertical lines have an undefined slope.)
Answer:
Step-by-step explanation:
<ACB = <ECD
These 2 angles are vertically opposite and are equal.
<B = <D
They are both right angles are therefore equal.
The answer is the AA postulate.
A
Note
ASA is a congruence postualate. If S is between two angles that can be shown to be corresponding and equal, then you will have 2 congruent triangles.
SSS if three sides of 1 triangle = 3 sides of a second triangle, then the 2 triangles are congruent. If the the three sides of one triangle are in a ratio with 3 sides of the other triangle, then the triangles could be similar, but that is not the case here.
SAS this is the terminology for congruence as well. We don't know enough to use it for similarity. Some sort of ratio would have to be mentioned to do that.
You are intended to use AA as your answer.
