Answer:
the possible line of best fit equation is;
y = 10x + 24
Step-by-step explanation:
Here, we want to get the approximate line of best fit
Mathematically, we have the general line of best fit as
y = mx + b
where m is the slope and b is the y-intercept
By joining the given lines, we can see that the y-intercept values fall a little below 30
This means that the possible y-intercept value is 24
Now, to get the slope value, we select any two points and use the slope equation
We can have (3,50) and (6,80)
Using the slope equation;
m = (y2-y1)/(x2-x1) = (80-50)/(6-3) = 30/3 = 10
The equation is thus;
y = 10x + 24
Answer:
The coordinates of triangle A"B"C" will become
A( 5,-3 ) B( 9,6 ) C( -12 ,-4 )
Step-by-step explanation:
Original vertices of triangle ABC are ;
A ( -3, 5 ) B( 6, 9 ) C ( -4, -12 )
after reflection over x-axis
A( -3,-5 ) B( 6, -9 ) C( -4,12 )
when the triangle is rotated
x coordinates becomes -y while y coordinates becomes x
The coordinates of triangle A"B"C" will become
A( 5,-3 ) B( 9,6 ) C( -12 ,-4 )
Well starting with just the first statement b is congruent to c by vertical... yes. because they are formed by the intersection and non adjacent. so A and C are still okay.
answer choice B on the other hand b is congruent to h by corresponding that is not true.. one they are not corresponding and two they are supplementary because they are same side exterior angles. so you can eliminate B.
now the next line in answer choice a.. c and e are supplementary by ss interior... yes that is correct.
now the next line in answer choice c.. d and h are supplementary.. that is wrong.. d and h are corresponding and therefore are congruent so you can eliminate answer choice C.
just checking the rest.. e and h are congruent by vertical.. correct.. and finally substitution to finish the proof. So A is the correct proof.
Step-by-step explanation:
option C
4=9+y
y=4-9= -5
