Answer:
Step-by-step explanation:
He had the incorrect slope for the second line, his line has a positive slope of one while the equation has a slope of negative 1.
x+y=1
y=-x+1
He graphed x+1 instead of -x+1
If he graphed them correctly the lines would intersect when the equations were equal
2x+4=-x+1
3x+4=1
3x=-3
x=-1, making y=2x+4 become
y=2(-1)+4
y=2
So the solution was supposed to be the point (-1,2)
Answer:
You could prove that ΔAMC and ΔBMD are congruent by AAS
Step-by-step explanation:
Step 1: Given
step 2: Vertical Angles Thm (the two triangles connect at a point)
Step 3: AAS (This is because segment AC is congruent to segment BD, Angle A is congruent to angle B, and ∠AMC is congruent to ∠BMD making the triangles congruent by Angle angle side.
Step 4: CPCTC
Hope I helped! And plus... LA is not a Congruence theorem and It would not be HL because there is only one congruent side given.
The first figure will create a cylinder
Answer:
so x = 5 is not true statement
Step-by-step explanation:
well to prove x = 5 you need to get get alone or solve for x
3x = 10-5 --> 3x = 5
now you need to get x alone do this by dividing 3 by both sides
3x = 5 --> x = 5/3
x = 1.6
Since the 9 is greater than or equal to 5, we'll round our number up by adding 1 to the 3 in the hundreds place, making it a 4. And also by changing all digits to the right of this new 4 into zeros.
And our rounded number would be 400
