In the first question,
Since D is the midpoint of line segment AC.
therefore, AD=DC.
In triangles, ABD & CBD.
Since, AB is congruent to CB and BD is a common side between those two triangles.
Therefore, AD is congruent to DC.
Finally, in triangles DEA & DEC
Since, ED line segment is a common side between those triangles and the measure of angle EDA is as the same of angle EDC which are equal to 90 degrees and AD is congruent to DC.
Therefore, triangle EDA is congruent to triangle EDC ( you have to take care of the triangle order letters in congruence) and EC is congruent to EA.
Answer:
D is the answer for the question
Answer:
y=3x4-3
Step-by-step explanation:
find the equation of the line parallel to the line −3x+4y=4 passing through the point (4,0).
The equation of the line in the slope-intercept form is y=3x4+1.
The slope of the parallel line is the same: m=34.
So, the equation of the parallel line is y=3x4+a.
To find a, we use the fact that the line should pass through the given point: 0=(34)⋅(4)+a.
Thus, a=−3.
Therefore, the equation of the line is y=3x4−3.
Answer: y=3x4−3.
Answer:
$29.75
Step-by-step explanation:
What you need to do is divide 51 by 12 to get 4.25.
Then you are going to multiply 4.25 by 7 to get 29.75.
You want to find your unit rate first.
Answer:
Step-by-step explanation:
Important Information:
Circumference of a cirlce=
Diameter=
Method:
The first step in working out the circumference of this cirlce is to work out the diameter. You can work this out by multiplying the radius of 12 by 2, this gives you 24cm. This is because the radius is half of the diameter.
The next step is to work out the circumference. You can do this by multiplying pi by the diameter of 24, this gives you or 75.4cm (1 d.p).
Step by Step:
1) Multiply 12 by 2.
2) Multiply pi by 24.
